Geneva Debut: 2010 Toyota Auris HSD [Video]

Toyota has announced that the 2010 Toyota Auris HSD, or Hybrid Synergy Drive, will officially go on sale in Europe later this spring. The car uses a 1.8-liter petrol engine and electric motor to provide nearly 62 mpg (US), consuming 3.8 liters of petrol per 100 km.


The petrol engine version it’s powered by a 1.8 L and a 60kW (80bhp) electric motor mated to a 27kWh nickel metal hydride battery. The car’s total power reaches 134bhp and can be driven in electric mode up to 30mph for 1.2 miles. The HSD meets Euro5 emissions standards and is expected to also comply with forthcoming Euro6 requirements. Auris HSD is scheduled to go on sale in July. Further details of performance, technical specifications, model grades and equipment features will be announced nearer the launch date.


Exterior design: a stronger, more confident road presence

Redesigned bumpers have increased the front and rear overhangs by 15 mm and 10 mm respectively. As a result the Auris 2010 has increased in overall length by 25 mm to 4245 mm, while the long, 2600 mm wheelbase remains unchanged.

With a new horizontal bar-type grille, more aggressive headlamp clusters, LED daytime running lights and a wider lower bumper air intake, the entire front of the Auris 2010 has been restyled to enhance the car’s stable, ground-hugging stance and create a more youthful image.

The rear design has been strengthened to provide a stronger, more confident road presence. The bumper corners have been extended outwards and create a new ‘catamaran’ bumper profile which accentuates the Auris 2010’s muscular proportions and wide track.

The latest addition to the model line-up, the Auris HSD incorporates several unique exterior design features which both improve the car’s overall aerodynamic efficiency and indicate the presence of Toyota’s Hybrid Synergy Drive® powertrain.

The upper grille opening has been optimised to help the air flow smoothly over the upper half of the body, and the size of the lower grille has been enlarged to reduce airflow resistance as well as improving engine cooling efficiency.

Housing a revised foglamp configuration, the flat, vertical surface of the bumper corner not only reinforces the Auris HSD’s broad stance and driving stability, but also corrects airflow as it passes over the front wheels to minimise wheel arch turbulence.

Allied to a 5 mm lowering of vehicle ride height and a choice of purpose-made, 15” or 17” alloy wheels with integrated, aerodynamic caps and low rolling resistance tyres, a large, roof mounted rear spoiler further improves the Auris HSD’s aerodynamic efficiency.

Acting in combination to smooth and control the flow of air over the car, these HSD-specific design modifications have reduced the Toyota hybrid’s coefficient of drag from Cd 0.290 to 0.283, effecting reductions in both fuel consumption and CO2 emissions.

The Auris 2010 is available in a choice of six exterior colours, including a new, hybrid-specific Pearl White finish.


Interior design: improvements in quality, ergonomics ?and visual appeal

Soft touch materials now cover the top of the driver’s instrument cluster and the upper glove box, and the seat upholstery has been upgraded across the range. The height of the centre console storage box has been raised by about 50 mm, and it now functions as an armrest. A new, more comfortable steering wheel incorporates redesigned audio and Bluetooth® phone control switches.

The unique, bridged centre console which brings the gear lever, handbrake and instrumentation within the closest possible reach of the driver has a new, bright metallic finish matched by the door handles. The handbrake design has been revised with a new lever release button, a tactile, ergonomic grip and lower seating in the release position.

Control panel colour and finish changes have enhanced switch layout visibility, and the illumination of the Optitron meter dials has been changed to white for improved clarity and visibility.

In conjunction with the introduction of Hybrid Synergy Drive®, the Auris HSD interior features several significant modifications. The driver’s instrument binnacle has been revised, with the tachometer replaced by an Eco Drive Assist Monitor. The centre-dial information panel includes additional, Hybrid Synergy Drive®-specific information such as Energy Flow and Eco Drive Result monitors.

A hybrid blue Smart Start switch has been added to the side of the instrument cluster. The centre console incorporates a Parking Control switch, EV, Eco and Power drive mode switches and a shift-by-wire transmission lever with a high-quality silver paint finish.

Auris HSD instrument and switchgear illumination has been amended to greenish white numbers on a hybrid blue background for the meter panel, audio and heating controls, and the Smart Start, Drive Mode and Parking Control switches.

A choice of hybrid-specific upholstery finishes features a standard specification, blue-flecked seat panel fabric, while high grade models are trimmed in Alcantara® panels with leather surrounds.


Powertrains and driving dynamics

• Hybrid Synergy Drive® full hybrid technology introduced to the Auris 2010 model range

• Toyota Optimal Drive technology applied to the full 3 petrol, 3 diesel engine range

• Overall Auris CO2 emissions support Toyota whole-fleet CO2 targets, already at 130 g/km in 2009

• All diesel engines available with Diesel Particulate Filter (DPF) or Diesel Particulate and NOx Reduction filter (DPNR)

• Revised suspension for improved ride comfort with high speed stability and secure handling

The Auris 2010 powertrain line-up features a choice of full hybrid drive, and three petrol and three diesel engines offering the performance- and economy-enhancing benefits of Toyota Optimal Drive. The introduction of a Hybrid Synergy Drive® model makes this is the most comprehensive range of powertrains available in the C-segment, catering for every customer requirement.

As a result of Toyota Optimal Drive technology, the Auris will be the first Toyota to comply with Euro 5 emission standards across the entire European model range by July 2010.

Starting at just 118 g/km, CO2 emissions have been lowered throughout the engine range, offering significant cost of ownership benefits to fleet customers.

The introduction of the Auris HSD will create an important shift in customer perceptions of full hybrid technology. The advantages of exceptional fuel efficiency and low CO2 emissions are obvious. However, the Auris HSD customer will also experience a smooth and sophisticated driving experience -unique to the C-segment- thanks to the everyday usability, driving comfort and remarkable quietness of Toyota’s multiple award-winning, full hybrid powertrain.

With remarkably low 89 g/km CO2 emissions the Auris HSD plays a significant role in further reducing Toyota’s whole-fleet CO2 average which, having fallen by 16 g/km between 2008 and 2009, already stands at just 130 g/km.


Hybrid Synergy Drive® - Full Hybrid technology

The new Auris HSD is a full hybrid capable of operating in petrol and electric modes alone, as well as a combination of both. Its Hybrid Synergy Drive® system delivers the energy-saving benefits of a series hybrid combined with the performance benefits of a parallel hybrid.
Full hybrid technology equips the new Toyota hatchback with impressive, seamless acceleration and remarkably quiet operation, while returning class-leading fuel efficiency and the lowest possible emissions.

The Auris HSD’s latest generation, series/parallel full hybrid system features a 1.8 litre VVT-i petrol engine, a powerful electric motor, a generator, a high performance battery and a power control unit. A power split device employs a planetary gear set to combine and re-allocate power from the engine, electric motor and generator according to operational requirements.
Key to the successful installation of Hybrid Synergy Drive® within the Auris front-engined platform, the electric motor, generator and power split device are all housed in one transmission casing the size of a conventional gearbox. The full hybrid drive system’s seamless, electric continuously variable transmission is controlled by shift-by-wire technology, using an electric shift lever system.

System power is provided by a lightweight, highly compact, 4-cylinder, 1798 cc, Atkinson cycle VVT-i petrol engine developing 98 PS (72 kW) at 5200 rpm and 142 Nm (105 lb-ft) of torque at 4000 rpm, and a high performance, permanent magnet, synchronous 60 kW electric motor generating a maximum 207 Nm (153 lb-ft) of torque from 0-13000 rpm.
Powered by the hybrid battery, the electric motor works in tandem with the petrol engine to boost acceleration during normal driving. The electric motor alone powers the driven wheels when the Auris HSD is operating in EV mode.

During deceleration and under braking, the electric motor acts as a high-output generator to effect regenerative braking. Normally wasted as heat, kinetic energy is recovered as electrical energy for storage in the high performance battery.

In combination, the 1.8 litre VVT-i petrol engine and electric motor generate a maximum system power output of 136 PS (100 kW), offering performance to match any conventional 2.0 litre diesel or petrol hatchback. Conversely, the Auris HSD returns low CO2 emissions of 89 g/km . In addition, the Auris HSD generates significantly lower NOx emissions than diesel engined cars of comparable performance.

Moreover, when operating in a unique, switchable EV mode, the Auris HSD offers zero CO2 and NOx emissions, driving for up to two kilometres at speeds of up to approximately 50 km/h, dependant on battery charge and driving conditions.


Unique Auris HSD eco driving experience

The Auris HSD offers four driving modes, including three on-demand modes, which not only maximise the capabilities of the Hybrid Synergy Drive® powertrain, but also incorporate comprehensive Eco driving support for those who wish to adopt more environmentally friendly driving techniques.

An EV mode allows for ultra-quiet running on electric motor power alone, resulting in zero fuel consumption and emissions; an ECO mode maximises hybrid system efficiency and fuel economy; and a POWER mode boosts system performance. In addition, an Eco Drive Monitor helps drivers maximise the fuel efficiency of Toyota’s Hybrid Synergy Drive® system.

Via the multi-information indicator in the combination meter, drivers may monitor the flow of energy within the Hybrid Synergy Drive® system for each driving mode. This helps them develop relaxed, fuel efficient driving techniques and maximise system efficiency. In addition, a simple yet clear power consumption gauge in the combination meter shows how much power is being used or generated at any given time.

Taking advantage of the inherent operational quietness of Hybrid Synergy Drive®, particular attention has also been paid to Noise Vibration and Harshness (NVH) reduction measures. This ensures customers enjoy a calm, quiet cabin environment at all vehicle speeds. Road and engine noise have been rigorously suppressed through the comprehensive use of sound-proofing materials. Full thickness glazing and an acoustic windscreen design further reduce wind noise for improved quietness at cruising speeds.


Toyota Optimal Drive applied to all petrol and diesel engines

Designed to optimise the balance of performance and driving enjoyment with fuel economy and low emissions, Toyota Optimal Drive focuses on several key aspects of powertrain development such as environmentally friendly technologies, low friction components, lightweight, compact design and enhanced combustion efficiency.

The application of Toyota Optimal Drive across the Auris range has significantly reduced CO2 emissions. The overall Auris CO2 average has been reduced from 152 g/km in 2007 to 142 g/km in 2009. In 2011, which will be the first full year of Auris range sales, the figure will reduce further to just 125 g/km.

Petrol engines

1.33 litre Dual VVT-i with Stop & Start system

The 1.33 litre Dual VVT-i petrol engine generates 73 kW/ 99 DIN hp and maximum torque of 128 Nm at 3800 rpm, while returning an average fuel consumption of 6.0 l/100 km and CO2 emissions of only 139 g/km.

The unit benefits from numerous Toyota Optimal Drive engine optimisations. A combination of lightweight technology, a resin cylinder head cover and intake manifold, and a remarkably compact design has effected a substantial reduction in engine weight and size. Combustion efficiency has been improved through the use of a high efficiency intake port, a high compression ratio and long reach spark plugs.

Extensive friction reduction measures include enhanced engine block rigidity and bore circularity, an improved valve roller rocker arm design with a new camshaft profile, small, lightweight pistons with a low friction coating, low viscosity oil and a water jacket spacer.

Toyota Optimal Drive’s environmental technologies are represented by the application of a wide ratio 6-speed manual transmission and optional, Stop & Start System technology.

This innovative system automatically switches off the engine when the vehicle is stopped. The world’s first permanently engaged ring gear mechanism allows for automatic engine restart within half a second when the clutch is lifted, with significant reductions in engine start noise and seat vibration levels.

Thus equipped, the 1.33 litre Dual VVT-i unit’s fuel consumption and CO2 emissions are lowered still further, to just 5.9 l/100 km and 136 g/km respectively.


1.6 and 1.8 litre Valvematic petrol engines

The 1.6-litre Valvematic engine develops 132 DIN hp and class-leading maximum torque of 160 Nm at only 4400 rpm. When equipped with a 6-speed manual transmission, the unit returns a combined cycle fuel consumption of 6.6 l/100 km and generates CO2 emissions of only 152 g/km. MultiMode transmission further reduces both fuel consumption and emissions, to 6.3 l/100 km and 146 g/km respectively.

The 1.8 litre Valvematic engine develops 147 DIN hp and maximum torque of 180 Nm at 4000 rpm, yet the engine’s combined fuel consumption is only 6.7 l/100 km, and CO2 emissions are 155 g/km.

Through the application of Toyota Optimal Drive, both engines benefit from the same lightweight technology, compact design and combustion efficiency engine optimisations as the 1.33 litre unit.

In addition, friction reduction measures include an improved valve roller rocker arm design with a new camshaft profile, small, lightweight pistons with a low friction coating, enhanced engine block rigidity and bore circularity, and low viscosity oil.
The environmental technologies of Toyota Optimal Drive are represented by the application of wide ratio 6-speed manual transmissions and an optional, MultiMode transmission available with the 1.6 litre unit.

Offering class-leading efficiency, power and torque, Valvematic is a further development of Toyota’s highly successful Dual Variable Valve Timing-intelligent (Dual VVT-i) system.
Adding lift and duration control to the variable inlet valve timing to deliver more power for less fuel consumption with reduced CO2 emissions, Valvematic also reduces friction and pumping losses under light engine loads, further lowering fuel consumption.

Diesel engines

The three diesel engines in the Auris 2010 model range also benefit from the extensive application of Toyota Optimal Drive technologies.

Lightweight technology and a compact design have resulted in a marked reduction in engine weight and size. Numerous combustion efficiency enhancing measures include a lower compression ratio, optimised combustion chamber dimensions, enhanced Exhaust Gas Recirculation (EGR) cooler efficiency and stainless steel exhaust manifolds with close-coupled Diesel Particulate Filters (DPF).

The adoption of Piezo injectors is of particular significance. Their high speed reaction time makes multi-phase high speed injection possible. This has the effect of both lowering the rate of combustion expansion and effecting a more thorough burn within the combustion chamber, thus further reducing particulate, NOx and CO2 emissions.

The 2.2 litre engine also benefits from Toyota’s Diesel-Clean Advanced Technology (Toyota D-CAT), which incorporates a Diesel Particulate and NOx Reduction filter (DPNR).


1.4 D-4D 90 diesel engine

The 1.4 litre D-4D engine develops 90 DIN hp and maximum torque of 205 Nm at only 1800 to 2800 rpm, and may be equipped with a Diesel Particulate Filter (DPF) for CO2 emissions that are amongst the lowest in the C-segment.

When equipped with the manual transmission and a CCo, the ?1.4 D-4D 90 unit returns a combined cycle fuel consumption of 4.7 l/100 km and generates CO2 emissions of only 124 g/km. Manual versions fitted with a DPF return just 4.5 l/100 km and a remarkable 118 g/km.

This outstanding, 118 g/km CO2 emissions performance has been achieved through combining Toyota Optimal Drive with various measures designed to maximise the aerodynamic and fuel efficiency of the Auris 1.4 D-4D 90, such as lowered suspension and low rolling resistance tyres.

2.0 D-4D 125 and 2.2 D-4D 180 diesel engines

With a DPF fitted as standard, the 2.0 D-4D 125 delivers ?126 DIN hp and maximum torque of 310 Nm from 1800 to 2400 rpm. Combined cycle fuel consumption is 5.2 l/100 km and CO2 emissions are 138 g/km.

The Auris’ powerful, 2.2 litre turbodiesel further benefits from Toyota’s Diesel-Clean Advanced Technology (Toyota D-CAT), which incorporates a Diesel Particulate and NOx Reduction filter (DPNR).

The 2.2 D-4D 180 unit delivers 177 DIN hp and a highly impressive maximum torque of 400 Nm between 2000 and 2800 rpm. Conversely, average fuel consumption is just 5.9 l/100 km, and CO2 emissions only 154 g/km.


6-speed manual and MultiMode transmissions

Every engine in the Auris 2010 range is mated to a Toyota Optimal Drive six-speed manual transmission featuring wide-spread ratios designed to optimise fuel consumption and lower CO2.

An optional, MultiMode transmission is available on 1.6 Valvematic petrol and 1.4 D-4D 90 diesel versions. MultiMode is an automated manual transmission with a fully automatic shift mode and no clutch pedal. It offers the driver a choice of two, fully automatic gear change modes or a manual, sequential gear change with steering wheel-mounted shift paddles.

Revised suspension and steering for an improved driving experience

Through close collaboration between Toyota’s European and Japanese Research and Development teams, the implementation of regional customer feedback and extensive European testing the Auris’ suspension system has been fine-tuned specifically for the customers and roads of the European market. It combines stable high speed driving performance with secure handling and superior ride comfort.

The Auris’ speed-sensitive Electric Power Steering (EPS) has also been revised and refined to provide better feedback and improved vehicle agility.

The Auris HSD brings the extraordinarily refined, smooth and silent Hybrid Synergy Drive® experience to a Toyota mainstream model customer base for the first time in Europe.

2010 BMW 5-Series ActiveHybrid Concept [Video]

The new concept car offers a particularly good rendition of the new BMW 5 Series Sedan in all its dynamic, efficient and innovative qualities, at the same time representing the ongoing development of the BMW ActiveHybrid X6 and the BMW ActiveHybrid 7 with their drivetrain technology already in production.

The drive system featured in the BMW Concept 5 Series ActiveHybrid consists of a straight-six gasoline engine with TwinPower Turbo technology, eight-speed automatic transmission, and electric drive. Integration of BMW ActiveHybrid technology in a sedan already extremely efficient with its "conventional" combustion engine reduces both fuel consumption and emissions once again by more than 10 per cent. At the same time the electric motor offers a boost function, supporting the gasoline engine in generating particularly dynamic drive power for an even more sporting driving experience in the car.

Intelligent energy management likewise serves to enhance the efficiency of the overall system, its unique functions ensuring appropriate control and management of all energy paths within the car and appropriate interaction of the drivetrain components precisely adjusted to driving conditions.

The drivetrain technology featured in the BMW Concept 5 Series ActiveHybrid allows all-electric, zero-emission motoring in city traffic. At the same time a special hybrid-based Auto Start Stop function offers additional efficiency by consistently switching off the combustion engine when stopping at the traffic lights, a road junction, or in congested traffic. Optimised comfort, finally, is provided by the auxiliary climate control function already featured in the BMW ActiveHybrid 7.


Special development of ActiveHybrid technology as part of BMW EfficientDynamics.

The concept car based on the new BMW 5 Series Sedan for the first time presents the next generation of BMW ActiveHybrid technology, a special solution exclusive to BMW for intelligent interaction of the combustion engine and electric drive focused specifically on the requirements made of a dynamic sedan in the upper midrange segment.

Taking this approach, BMW is consistently continuing the development of hybrid technology according to a modular principle (best of hybrid), thus offering the optimum rendition of BMW ActiveHybrid technology for each concept and vehicle segment.

In accordance with the BMW EfficientDynamics development strategy, this ensures highly effective and practical use of hybrid technology for the reduction of both fuel consumption and emissions.


Also in the BMW Series Sedan segment: the BMW among hybrids combines supreme dynamics with maximum efficiency.

The combustion engine is supported in the BMW Concept 5 Series ActiveHybrid by an electrical drive system developed specifically for this model and arranged in compact dimensions between the straight-six combustion engine and the automatic transmission. Drawing its energy from a high-voltage battery at the back of the car, the electric motor develops maximum output of 40 kW.

An automatic clutch connects the gasoline engine and the electric motors.

Due to the particularly high level of torque generated from the start through the electric motors, the interaction of the two drive systems ensures extremely spontaneous and dynamic acceleration whenever required.


Perfectly integrated, precisely controlled: high-voltage battery supplying power to both the electric motor and the on-board network.

In overrun and when applying the brakes, the electric drive systems acts as a generator developing electric power fed into the high-voltage battery. This converts kinetic energy otherwise wasted as heat in the brake system into electric power saved for subsequent use.
Such energy obtained without any further consumption of fuel may then be used to generate drive power or operate electrical functions in the car.

This principle is the same as that of Brake Energy Regeneration already applied in BMW's current production models, with the level of electrical energy generated by the electric motor being significantly greater and the increase in efficiency correspondingly higher.

The high-voltage battery likewise developed for this specific concept is fitted within a high-strength special case near the rear axle of the BMW Concept 5 Series ActiveHybrid. This leads to an optimum position in terms of both safety and harmonious weight distribution. An integrated control unit permanently analyses the charge status of the high-voltage battery and controls both the battery charge process by way of Brake Energy Regeneration and the system cooling process. Apart from the electric motor, the high-voltage battery also delivers electric power to the car's on-board network. Among other things, this allows efficient operation of the car's auxiliary climate control activated whenever required by a remote control function to cool down the car's interior significantly even before starting the engine.

Convenient use of the all-electric driving mode and the Auto Start Stop function is likewise guaranteed in this way, with all electrical functions such as the audio system, climate control or navigation remaining fully available even with the combustion engine switched off.


Unique: intelligent energy management with advance analysis of driving conditions.

BMW ActiveHybrid technology provides its unique potential in terms of both efficiency and driving dynamics under all kinds of conditions and throughout a wide load range.

Unlike conventional hybrid cars whose extra efficiency is largely limited to city traffic, both the BMW ActiveHybrid X6 and the BMW ActiveHybrid 7, by combining the combustion engine and the electric motor, are able to offer significantly lower fuel consumption and emission ratings also at higher speeds. This is made possible by technically sophisticated power electronics masterminding the interaction of the combustion engine and electric motor and thus optimising the overall efficiency of the drive system as a whole.

The BMW Concept 5 Series ActiveHybrid once again raises the range of functions provided by such power electronics to an even higher standard. As an example, the energy contained in the fuel and provided by the high-voltage battery may now be used even more specifically and efficiently to provide that Sheer Driving Pleasure so typical of BMW.

Taking additional factors into account, the interaction of the two drive units in the BMW Concept 5 Series ActiveHybrid is tailored to the driver's requirements and current driving conditions with maximum precision. At the same time the power electronics also control the operation of the car's ancillary units and comfort functions, again in the interest of maximum efficiency.

The range and diversity of parameters taken into account by the system is indeed quite unique in the automobile, just as the number of functions controlled in this way. A high level of all-round networking allows the power electronics to provide intelligent energy management, thus optimising the operating strategy of the entire vehicle under all conditions.

A further unique feature of energy management in the BMW Concept 5 Series ActiveHybrid is the car's ability to adjust its operating strategy not just to current, but also to upcoming driving conditions. To do this the power electronics from the start evaluate data indicating a possible change in exterior conditions or the driver's wishes and prepare the components in the drivetrain as well as the car's electronic system for a possible change in requirements.

To analyse driving conditions up front, the system uses data provided by engine and chassis management as well as the sensors in the driver assistance systems on board the car. Data saved in the navigation system on the route chosen by the driver likewise goes into the final calculation, enabling the system to forecast driving conditions on the route directly ahead. Then, proceeding from this analysis, the car is coordinated in advance and the optimum use of all systems serves to use the energy available with maximum efficiency.

Should the system determine, for example, that the autobahn ahead is about to lead downhill, the charge level of the high-voltage battery is intelligently controlled in advance to regain brake energy upfront with maximum efficiency.

Similarly, the high-voltage battery may be fully charged in good time before the driver reaches his destination, enabling the system to switch off the combustion engine at an early point and change to all-electric drive along the final stretch of road. Indeed, this forward-looking function is able to extend the cruising range on electric power by up to 30%.


The BMW Concept 5 Series ActiveHybrid: the future of driving pleasure and efficiency in the upper midrange segment.

Optimised to an even higher standard in the BMW Concept 5 Series ActiveHybrid, the drivetrain and control systems underline the great significance of hybrid technology as a cornerstone of BMW EfficientDynamics. Looking at a new generation of hybrid technology from BMW featured in the BMW Concept 5 Series ActiveHybrid therefore offers particularly attractive perspectives, the ongoing development of BMW ActiveHybrid technology serving to provide substantial progress in all areas leading to a harmonious all-round concept with distinctive features typical of the brand.

The BMW Concept 5 Series ActiveHybrid is therefore more dynamic, efficient and more intelligent than conventional representatives of this drive technology, standing out clearly as the BMW among hybrid cars in this segment.

Leak: Ferrari 599 Hybrid Concept

We've been hearing a lot about Ferrari's Geneva-bound 599 Hybrid concept model for quite some time now, but the Italian supercar maker apparently can't keep it under wraps anymore as the first photos of the prototype model made it onto the web today.


In response to initial reports, Ferrari chairman Luca di Montezemolo confirmed during the Ferrari F10 Formula 1 car launch that a 599 hybrid concept was indeed under development. Now photos have surfaced from a private presentation and they are quite detailed.


The system comprises of an electric motor producing somewhere around 100 horsepower and 137Nm (110 lb-ft) of torque that is attached on the back-end of the rear-mounted transmission, and a battery pack located under the floor.


Looking at the photos with strategically placed mirrors for optimum viewing, we can see the electric motor attached to the rear of the differential. Located just beneath the floor pan is the battery labeled "Danger High Voltage."


Last but not least, we were told that the hybrid system is still in its infancy stage and will most likely take a few years to be offered on a series production model.

• Long, 2,600mm wheelbase ensures excellent accommodation for everyone on board
• Debut at Geneva motor show prior to worldwide sales launch in late 2010

Exterior and interior design

The production-ready CT 200h retains strong visual links to the LF-Ch concept Lexus unveiled at the 2009 Frankfurt motor show. Its styling marks a powerful evolution of Lexus's L-finesse design philosophy with a distinctive, sharp-edged look that sets it apart from its premium compact rivals.

The exterior is styled for maximum aerodynamic efficiency and minimum wind noise. The strong front grille, directly referencing the LF-Ch concept sits over a full-width bumper and air dam. The headlamp units, positioned higher than the grille (a signature feature of L-finesse design), incorporate LED daytime running lights.

In profile, the steeply raked windscreen, long, flowing roofline and Lexus slingshot window graphic combine to create an elegant and distinctive silhouette. The front and rear corners have been pulled in tight and the wings are styled to improve airflow down the sides of the vehicle.

At the rear, the trailing edge of the roof overhangs a wide, wraparound rear window to create a seamless, integrated spoiler. A pronounced step in the tailgate section flows from the shoulders of the rear wheelarches and is anchored by a tail lamp design that displays the L-shaped motif that Lexus first introduced on the current LS model.

The interior combines superior ergonomics with extensive use of metallic finishes and dark, soft-touch surfaces.

Lexus has retained the asymmetrical dashboard design seen in the LF-Ch show car. Based on the Future Lexus Interior concept, the dashboard is split into an upper Display Zone, with an eight-inch LCD multi-display screen; and a lower Operation Zone, with the shift lever and other controls such as Lexus's Remote Touch multi-function controller.

In keeping with the car's performance, the driving position is set low, with a highly supportive driver's seat. The instrument binnacle houses large, twin dials; in SPORT mode, the hybrid indicator in the binnacle functions as a tachometer and the ambient lighting turns from blue to red. The two-mode switch ring and a spotlight in the centre cluster also light up in red, changing the whole atmosphere of the cabin.

In spite of its compact, efficient design, the CT 200h offers a roomy interior. The 2,600mm wheelbase allows for front and rear passenger accommodation that is among the most spacious in the segment. Luggage capacity is 345 litres, increasing to 700 litres with the rear seats lowered.


Lexus Hybrid Drive

The Lexus Hybrid Drive system in the CT 200h combines a 1.8-litre VVT-i petrol engine with a powerful electric motor. Drivers have the choice of four selectable drive modes: ECO and NORMAL place the emphasis on efficiency and comfort, while SPORT focuses on dynamic performance.

Unlike mild hybrid systems used by other manufacturers, the CT 200h also has an EV (electric vehicle) mode that allows for ultra-quiet running on the electric motor alone, resulting in zero fuel consumption and CO2, NOx and particulate emissions. The car is capable of running in EV mode for up to 1.2 miles at speeds up to 28mph.


Chassis and suspension

The CT 200h is built on a new platform with a dedicated double wishbone and trailing arm rear suspension system. It has been developed specifically to combine the ride comfort expected of a Lexus with superior driving involvement and handling agility.

Several elements in the MacPherson strut design have been exclusively developed for the mode, including the coil springs and shock absorbers, and a new front anti-roll bar has been designed to deliver improved roll rigidity.

The double wishbone rear suspension is exclusive to the CT 200h and incorporates a lightweight trailing arm. The springs and shocks are positioned separately to minimise intrusion into the loadspace floor.

Efficiency paired with elegance:
Pioneering premium sedan with "green" technology and avant-garde design

• A reinterpretation of the concept of "fascination and responsibility"

• Multi-drive platform enables use of two alternative drive systems - either Plug-in Hybrid or fuel cell

• Intelligent display concept focusing on "electric driving"

• HMI with cam touchpad for intuitive and precise operation

• Traffic Jam Assistant for increased comfort and safety

Mercedes-Benz' F800 Style research vehicle is showing the future of premium automobiles from a new perspective, as the five-seat premium sedan combines highly efficient drive technologies with unparalleled safety and convenience features and an emotive design idiom, which interprets current Mercedes-Benz styling in line with the brand's hallmark attribute of refined performance.

The F800 Style has a spacious interior full of intelligent seating, operating, and display concepts. Another unique feature of the large sedan is an all-new multi drive platform, which accommodates electric drives with fuel cells (enabling ranges of almost 375 miles) as well as the use of Plug-in Hybrids that can drive for up to 18 miles solely on electricity. Both variants of the F800 Style therefore make locally emission-free mobility possible at the level of a premium-class automobile, while at the same time being fully suited for everyday driving and providing a dynamic driving experience.

"We are dedicated to reconciling our responsibility for the environment with practical customer utility in a fascinating automobile," says Dr. Thomas Weber, the Daimler Board of Management member responsible for Group Research and Mercedes-Benz Cars Development. "The new F800 Style research vehicle combines this commitment to providing the leading innovative drive concepts with our traditional Mercedes strengths in the areas of design, safety, comfort, and outstanding performance."


A glance into the future of pioneering premium sedans

Within the 15.5-foot external length of the F800 Style, all of the components of the vehicle's efficient and environmentally compatible alternative drives (Plug-in Hybrid or fuel cell drive system) are installed in a space-saving manner in the engine compartment and the gaps within the chassis. Each of the drive systems takes up comparatively little space for the installation. This applies in particular to the electric drive with fuel cell, which has been enhanced by Mercedes-Benz to be compact and powerful. The front end's compact package was made possible through the consistent downsizing of all F-CELL components. As a result, the entire interior space is preserved and offers plenty of room for five occupants.

"For many decades now, our research vehicles have been turning pioneering concepts into reality and thereby setting future trends. We set a course on the large touring sedan segment in 2007, when we presented the F700," says Prof. Herbert Kohler, Head of E-Drive & Future Mobility and Chief Environmental Officer at Daimler. "Characteristic features of the F800 Style are its innovations, whose development is already close to the series production stage. This is true not only of the electric drive with fuel cells but also of the Plug-in Hybrid, whose components were taken from our modular system for electric and hybrid vehicles."


F800 Style with Plug-in Hybrid: Outstanding performance despite emissions of only 68 grams CO2 per kilometer

In combination with the very powerful Plug-in Hybrid drive system, the F800 Style is a very dynamic expression of the concept of "fascination and responsibility." Its drive unit consists of a V6 gasoline engine with an output of 300 hp with next-generation direct injection and a hybrid module with an output 109 hp so that it delivers a total power of around 409 hp. The lithium-ion battery with a storage capacity of >10 kWh can be recharged either at a charging station or a household power socket. Thanks to its powerful and high-torque hybrid module, in the city the F800 Style can run exclusively on electricity, therefore without generating any local emissions. Because it also has high torque right from the moment it starts, the vehicle has the same driving performance as a car with a V6 gasoline engine even when operating in electric mode. The F800 Style with the Plug-in Hybrid can run purely on electricity for up to 18 miles. The F800 Style research vehicle therefore marks a further important step in the creation of a market-ready Plug-in Hybrid. Mercedes-Benz will begin series production of the S500 Plug-in Hybrid with the introduction of the next-generation S-Class.

Due to its efficient drive system and a CO2 bonus for the battery-electric driving mode, the vehicle has a certified fuel consumption of only 2.9 liters of gasoline per 100 kilometers. This corresponds to extremely low CO2 emissions of only 68 grams per kilometer. However, thanks to its outstanding efficiency, the F800 Style equipped with a Plug-in Hybrid nevertheless has a driving performance comparable to a sports car (0-60 mph 4.7 s, top speed of 155 mph). When in electric mode, the F800 Style has a top speed of 75 mph, thus meeting the needs associated with long-distance driving.

Like the Mercedes-Benz S400 HYBRID introduced in the summer of 2009 and the Vision S500 Plug-in Hybrid, the powerful electric module (approx. 80 kW) of the F800 Style is completely integrated into the housing of the seven-speed transmission. The lithium-ion battery in the new research vehicle is located underneath the rear seat, where it takes up little space, creates a low center of gravity, and ensures maximum safety in the event of a crash.

The electric drive components in the F800 Style with the Plug-in Hybrid once again demonstrate the versatility of Mercedes-Benz' extensively scalable modular hybrid system. The hybrid system can be expanded in various ways, depending on performance needs and the area of application. On this basis, it is possible to combine hybrid modules and batteries of different performance ratings with fuel-efficient, high-torque gasoline and diesel engines. Examples range from the current mild hybrids all the way to Plug-in Hybrids that enable pure electric driving over long distances. In developing the F800 Style with Plug-in Hybrid, the Mercedes engineers specifically focused on improving the pure electric driving in urban traffic. Thanks to high power reserves, the F800 Style in e-mode easily masters all kinds of city traffic while producing no local emissions. With the new hybrid module, the top speed of the F800 Style with Plug-in Hybrid has been increased to 75 mph in electric mode compared to the Vision S500 Plug-in Hybrid. At the same time, it emits only 68 grams of CO2 per kilometer, compared to the latter vehicle's 74 grams per kilometer.


Flexible, secure, and fully suited to everyday use:
The F800 Style with electric drive and fuel cell technology

The F800 Style also offers clean driving pleasure in the variant equipped with an electric drive based on fuel cell technology. The vehicle's electric motor develops around 136 hp as well as a strong torque of approximately 214 lb-ft. The fuel cell generates the traction current by chemically reacting hydrogen with oxygen onboard the vehicle, producing water vapor in the process as the only emission.

The components of the fuel cell drive are taken from the range of available e-drive modules, which Mercedes-Benz developed for a variety of different electric vehicles. These components, which are already installed in the limited edition B-Class F-CELL, can be used flexibly and are suited for a variety of different drive configurations. The F800 Style is an example of this, as it uses rear-wheel drive, in contrast to the B-Class F-CELL. The same components are also installed in commercial vehicles, with developments here being spearheaded by the new Citaro fuel cell bus, which is equipped with two of the F-CELL systems used in passenger cars.

The new Mercedes-Benz research vehicle has the fuel cell located in the front, while the compact electric motor is installed near the rear axle. The lithium-ion battery is located behind the rear seats and is protected as well as possible against the effects of accidents, as are the four hydrogen tanks. Two of the tanks are located in the transmission tunnel between the passengers, while the other two are underneath the rear seat.

F800 Style with further innovations for more comfort and safety

In addition to a multi-drive platform that is unparalleled for large sedans and the combination of different alternative drive technologies, the F800 Style features many other technological innovations, such as a new multi-function display concept and a human-machine interface (HMI) with a cam touchpad. The display shows many additional functions not typically found in conventional instrument clusters. The F800 Style's display concept focuses for the first time primarily on electric driving functions.


HMI with cam (camera) touchpad for intuitive and precise operation

The new cam touchpad HMI is an intelligent expansion of the COMAND system. For many years now, Mercedes-Benz has been forging ahead with the development of innovative operating and display systems. A particularly user-friendly innovation is being presented in the F800 Style. The HMI unit here consists of a touchpad on the center console and a camera that records video images of the user's hand as it works the pad. The live image of the hand is presented in transparent form in the central display above the console. The user sees the contours of his or her fingers glide across the image without covering anything, thus ensuring that all of the functions of the currently used menu remain visible so that they can be easily operated by applying slight pressure to the touchpad. Pressing the display with one's fingers generates a feeling similar to that of touching laptop keys so that users know when they are carrying out specific actions.

The cam touchpad HMI unit recognizes finger movements on the pad surface such as wiping, pushing, turning, and zooming, thus enabling intuitive regulation of the climate control system, telephone, stereo and navigation systems, and Internet access. The unit enhances active safety as well, because it is extremely easy and convenient to use and therefore does not distract the driver as much from the actual task of driving. And unlike conventional touchscreens, the HMI cam touchpad does not get smudged with fingerprints.

Conventional touchpad units generally depict hand or finger positions only by a small point in the display. Their lack of precision makes it very risky to enter information while driving, because doing so diverts the motorist's attention too much from the road. By contrast, the HMI with cam touchpad can be easily and safely operated even while driving. Test subjects have confirmed that the HMI with cam touchpad is extremely easy and safe to use, particularly as a result of the transparent depiction of the hand.

Range on Map: Graphic range depiction during electric operation

Another very user-friendly innovation created by the Mercedes engineers is the "Range on Map" function, which shows the remaining possible travel radius during electric vehicle operation as a 360° depiction on a map. Should municipalities only permit purely electric automobile traffic in the future, the driver can determine whether the electric range of his or her vehicle is sufficient for the journey into and out of the urban area by means of the Range on Map function. The system provides this function by combining information on the current battery charge level with data from the navigation system.

In the new operating and display concept, Mercedes-Benz has created a solution that provides an unparalleled amount of information in a system of exemplary clarity. The engineers have thus achieved the goal of successfully developing a comprehensive yet easy-to-operate information and control system for future automobiles equipped with electric or partially electric drive systems. A further-developed version of the system can also display recharging stations.


Mirror display is easy on the eyes

The mirror display of the innovative cam touchpad HMI eliminates the differences between close proximity visibility and visibility over longer distances, thus contributing to the driver's physiological safety in a manner typical of Mercedes. The system displays driving and vehicle information via a mirror in the instrument cluster so that they appear to be farther away. The distance the eye looks into is thus extended, which means less switching between near and far focus - and therefore less fatigue - for the eyes.

New DISTRONIC PLUS Traffic Jam Assistant further reduces the stress of driving

Back in 2006, Mercedes-Benz introduced DISTRONIC PLUS, the world's first proximity and speed control system that operates even when the car is standing still. The system substantially reduces the stress for drivers in dense traffic, as it regulates the distance from the vehicle in front even at very low speeds all the way down to a standstill. With its new DISTRONIC PLUS Traffic Jam Assistant feature in the F800 Style, Mercedes-Benz has also become the world's first automaker to implement a system that is also capable of automatically following the vehicle in front of it into curves. The system recognizes the difference between driving along curving roads and turning, which means it does not "blindly" follow the vehicle up in front - for example, when it changes lanes in order to exit the highway.

The result is that at speeds of up to about 25 mph, the Traffic Jam Assistant function takes care of both longitudinal and transverse movements so that drivers do not have to steer themselves. The driver can just sit back and relax - with hands on the steering wheel. When the 25 mph mark is exceeded, the steering torque that keeps the vehicle in its lane is gradually reduced to a point at which the Traffic Jam Assistant smoothly disengages. Drivers can, of course, override the system at any time. Sensitive sensors notice active steering movements, thus automatically deactivating the system's lateral control function.

"The DISTRONIC PLUS Traffic Jam Assistant is the logical continuation of the Mercedes-Benz assistance and safety philosophy. With it, we are setting another milestone on the path toward creating innovative systems, with which we will further enhance the high driving comfort that is a hallmark of Mercedes," says Prof. Bharat Balasubramanian, Head of Product Innovations & Process Technologies at Group Research and Advanced Engineering. The required data is generated by radar distance sensors that are supplemented by a stereo camera.


PRE-SAFE 360° improves safety in rear-end collisions

While the Traffic Jam Assistant heightens comfort and active safety, the innovative protective system known as PRE-SAFE 360° further improves passive safety. PRE-SAFE 360° is based on the proactive occupant protection system PRE SAFE® developed by Mercedes-Benz. Unlike the previous system, PRE-SAFE 360° also monitors the area behind the vehicle. As a result, the system engages the brakes around 600 milliseconds before an anticipated rear-end collision occurs. The key advantage of this system is that braking a stationary vehicle helps prevent secondary accidents such as those that occur when the car is pushed uncontrolled into an intersection or a pedestrian crossing. It goes without saying that PRE-SAFE 360° also allows the driver to take control at any time. For example, the brake is immediately released if the driver hits the gas pedal, should they recognize that there is sufficient space in front of their vehicle to avoid the rear impact.

Rear pivot-and-slide doors ensure maximum entry comfort

A particularly customer-friendly innovation of the F800 Style is its rear doors. Whereas the front doors are attached to the A-pillar in a conventional manner and open wide toward the front, the rear doors slide backward when opened, as they are suspended from an interior swivel arm. Because the doors slide back close to the vehicle body, occupants find it much easier to get into and out of the automobile in tight parking spaces.

The F800 Style also has no B-pillar, making the entire space between the A and C-pillars completely accessible when the doors are opened. Despite the lack of a B-pillar, the F800 Style boasts a bodyshell that is both extremely robust and lightweight, and that meets the stringent demands for crash safety that are a hallmark of the Mercedes brand.

Reinterpretation of the typical Mercedes-Benz design idiom

The F800 Style is both a technology platform and a showcar. This research vehicle was created through close cooperation between technical research and advanced engineering departments and the advanced design studios in Sindelfingen, Germany and Como, Italy. Its exterior appearance is marked by a long wheelbase, short body overhangs, and a sensually flowing roof line.

"The exciting coupe-like roof line, and in general the vehicle's balanced proportions, lend it a stylish sporty look that reinterprets the Mercedes-Benz design idiom and emphasizes the sculptural character of the F800 Style," says Mercedes-Benz Head of Design Prof. Gorden Wagener. "The result is a harmonious blend of innovative form and function, which conveys a sense of great styling and authority."


Front end with distinctive LED headlights

The vehicle's front end features a variation of the radiator grille with the centrally placed star that is typical of Mercedes sports cars. The curved radiator grille bars softly flow around the tube holding the Mercedes-Benz brand star. Along with the wide radiator grille and the generously curved air intake openings, the model's unique bright LED headlights emphasize the dynamic nature of the research vehicle. The headlights are divided into individual segments for daytime running lights, turn signal indicators, and primary headlights. The F800 Style's taillights are also equipped with state-of-the-art LED units that enable an exciting interplay of indirect illumination and direct beams. The result is an attractive, unmistakable, and memorable visual effect.

Wood and light create a cozy interior

Luxurious wood surfaces and lots of light ensure a high level of comfort in the interior of the F800 Style. Occupants will immediately notice the modern sense of lightness, and functional elements like the driver area and the door armrests seem to float in space like sculptures. The innovative lightweight-construction seats in the F800 Style consist of a magnesium shell and a carbon fiber laminate shell backed with a fine yet resistant netting. The seat shell also features genuine wood veneer. For the veneer process, Mercedes-Benz engineers used a 3D surface coating procedure designed especially for the veneering of three-dimensional surfaces. This same procedure was used to create the wood finish in the center console, on the doors, and in the driver area. These wood finishing pieces are molded as 3D laminated components and are augmented by an aluminum core, which ensures that the components meet the high crash safety standards that are a hallmark of Mercedes.

Successful transfer from research to series production

Mercedes-Benz has presented 13 research vehicles since the early 1980s. The range of innovative and pioneering automobiles that was unveiled - beginning with Auto 2000 in 1981 and leading up to today's F800 Style - offers proof of the consistency and foresight with which Mercedes-Benz engineers address the core issues of research and technology in order to develop innovative solutions for the future. Many systems that were first used in research vehicles and viewed as revolutionary at the time are now found in Mercedes-Benz production cars, including the DISTRONIC proximity-controlled cruise control, which was first installed in the F 100 in 1991 and made its series production debut in the S-Class in 1998.

The F800 Style is continuing this approach. Like its predecessors, the model features important drive, comfort, and safety system innovations, as well as an avant-garde design, all of which point the way forward for future series- production Mercedes-Benz vehicles that will continue to impressively combine fascination and responsibility.

Geneva Preview: 2010 Opel Flextreme GTE Concept

Rüsselsheim. Opel will unveil its Flextreme GT/E concept car at the 80th Geneva Motor Show (March 4 – 14), that will boost the company’s credentials as a leader in green technologies, offering expressive design with efficient environmental performance – and engineered with German precision.

In Opel’s strategy for achieving more independence from fossil fuels, electricity plays a key role. The 4.7-meter long Flextreme GT/E concept illustrates how extended-range electric vehicle (E-REV) technology can be plugged into large or mid-size vehicles, as well as compact cars such as the upcoming Ampera.

Opel calls this strategy e-mobility unlimited: adapting the highly efficient E-REV drive system – which removes the limitations of battery-only power – to vehicles across all market segments. To enjoy zero CO2 driving emissions Opel-style, the Flextreme GT/E concept shows that size doesn’t matter.

The purposeful design also enables the Flextreme GT/E to achieve a projected drag co-efficient of just 0.22, which helps it reach a 200 km/h-plus top speed as well as conserve energy and extend its driving range. Stand-out visual features include a low and wide stance, wing-shaped lights front and rear, a distinctive nose and grille, floating C-pillars and muscular, sculptured bodywork.

“The Flextreme GT/E concept shows the shape of things to come from Opel,” says Frank Weber, Vice President, Corporate and Product Planning. “Bold, expressive and highly efficient, it represents the product strategy we will apply to all our future vehicles, large and small, across all market segments.”


Exterior design: expressing efficiency with emotion

The low, coupé-like proportions of the Flextreme GT/E explore the potential for evolving Opel’s new design language – sculptural artistry meets German precision – within an envelope optimized for aerodynamic efficiency.

The clean, frontal styling features a low hood line and an extended nose section, which is clasped by wing-shaped, signature LED headlamps. These are deeply carved into the front fenders and across the hood line. The new trapezoidal grille execution is slim but bold. The prominent wing-shaped chrome bar carries a large Opel emblem, which doubles as a socket for charging the Flextreme GT/E’s battery pack.

The upper section of the grille is used to admit cooling air, the lower portion being covered by a translucent panel. The absence of additional air intakes allows a low frontal area for aerodynamic efficiency and also enables the Flextreme GT/E to meet future pedestrian protection requirements.

The sculpted hood, with an Opel signature central crease line, features narrow longitudinal vents on either side to draw air out of the engine compartment. The muscular fenders and wheel-arches sweep back into the side-body.

In profile, the Flextreme GT/E is distinguished by innovative, stubbed C-pillars. This floating design allows the glasshouse to be extended rearwards under the arching roofline, emphasizing the flowing lines of the side body. The car’s dynamic character is further underlined by a fresh expression of Opel’s signature blade motif, now a swooping swage line from the base of the C-pillar into the lower front fender.

Access to the cabin is enhanced by the adoption of rear-hinged rear doors, an evolution of the Opel FlexDoors concept from the new generation Meriva monocab. To preserve the clean exterior looks, all door handles are replaced by light sensors. These trigger the doors open when covered by the driver’s or passenger’s hand. To reduce air turbulence, exterior front door mirrors are also absent, replaced by small camera pods in the base of the A-pillars.

At the rear, a strong shoulder line embraces sculpted wheel-arches that further emphasize the Flextreme GT/E’s wide, ground-hugging stance. The coupé look is completed by a steeply raked tailgate, carrying wing-shaped LED light units which echo the form of the front headlamps. Like that of the Insignia Sports Tourer, the tailgate has a wraparound design for improved trunk access. Its deep glass screen is slightly convex to improve airflow.

The translucency of the fixed glass panel in the center of the roof is adaptive, allowing sunlight to warm the interior in the cold of winter, but darkening for coolness in summer. A duct at the rear edge of the roof is for additional cooling of the battery and electronic components.


Managing airflow and saving weight

Integral to the Flextreme GT/E’s expressive looks is the efficiency of the design execution. The small frontal area, low roof height (1308 mm) and a flat, enclosed underbody all enable the car to cleave the air with a minimum of disturbance.

A series of measures optimize airflow management. The 21-inch alloy wheels are relatively narrow, to reduce wind resistance, and fitted with 195/45, low rolling resistance tires. Clear, flush-mounted trim inserts also minimize air turbulence.

The minimal front intake improves airflow around the nose of the car and the underbody sweeps up, venturi-like, at the rear to further reduce drag.

The Flextreme GT/E also explores the potential for active shape shifting. At speeds above 50 km/h, a vertical panel extends along the body from the air extraction slot behind each rear wheel-arch. These 350 mm-long side spoilers guide high-speed airflow around the rear corners of the car, further reducing the amount of turbulence.

Mass reduction measures for the body include the use of lightweight, carbon composite outer panels, polycarbonate window glazing and aluminum alloy structural components. Compared to conventional materials, these offer a 40 percent weight saving which further contributes to reduced energy consumption and an increased driving range.


Innovative propulsion

The efficient concept also includes GM’s ground-breaking E-REV drive system, already developed for the Opel Ampera. The Flextreme GT/E shows the versatility of this technology by displaying it in a larger, mid-size vehicle format.

Despite its greater size and a maximum speed of more than 200 kilometers per hour, the Flextreme GT/E is projected to offer performance similar to that of the Ampera: a battery-powered driving range of up to 60 km – with zero CO2 tailpipe emissions – and a total range of more than 500 km. Average fuel consumption is estimated at 1.6 l/100 km, with CO2 emissions of less than 40 g/km.

Unlike a hybrid vehicle, the wheels of the Flextreme GT/E are powered at all times by electricity. For typical journeys up to 60 km, energy is supplied by a T-shaped lithium-ion battery pack located under the floor and rear seat.

However, unlike a battery-only electric vehicle, the Flextreme GT/E eliminates any possibility of range anxiety through fear of being stranded without power. The small gasoline engine/generator is seamlessly engaged to provide electricity whenever the battery’s supply becomes depleted. In this mode, the driving range is extended to more than 500 km, until the plug-in battery pack can be recharged or the car is refueled.

The motor in the electric drive unit delivers a substantial 370 Nm of instant torque, giving lively performance and projected zero to 100 km/h acceleration in less than nine seconds.

The Flextreme GT/E concept is a further step in Opel’s unfolding strategy for the electrification of the automobile, which includes a wide portfolio of products using battery, extended-range, hybrid and fuel cell technologies.

Through development of a flywheel for Williams F1's Kinetic Energy Recovery System, WHP has proved its world-class engineering capabilities in the composite flywheel field as well as radically improving aspects of the technology in the process. WHP is today making the technology available to meet the high-power energy storage needs in a variety of applications including hybrid passenger vehicles, hybrid buses, electric trains, diesel-electric ships and wind power generation. In November 2009, the company announced its involvement in a mild hybrid road car programme with Ricardo, CTG, JCB, Jaguar Land Rover, SKF and Torotrak. The project aims to demonstrate the potential of flywheel-based hybrid systems with the potential for 30 per cent fuel savings (and equivalent reductions in CO2 emissions) at an on-cost of less than £1000, to enable mass-market uptake of hybrid vehicles in price sensitive vehicle applications.
