GMAC to provide financing for Saab dealers and customers

2010 Saab 9-3X

* GMAC chosen as financial services provider to Saab Automobile
* Preferred source of wholesale and retail financing for dealers and customers

Trollhättan. Following its successful launch as an independent company, Saab Automobile announced today that it has selected GMAC Financial Services as the preferred provider of wholesale and retail financial services for qualified Saab dealers and customers in many different countries around the world.

Geneva preview: Fiat Two-Cylinder 85 HP TWIN-AIR Engine


The new two-cylinder engine family made by FPT - Fiat Powertrain Technologies called TWIN-AIR will be making its debut at the Geneva Motor Show. This is a brand-new concept on the worldwide auto scene and confirms the leadership of the Fiat Group in this field.

Using next-generation technology, the new engine implements the revolutionary Multiair system combined with special fluid dynamics optimised for the best fuel efficiency. Furthermore, by taking the concept of downsizing to the extreme and masterly tuning the basic mechanics, the new family - delivering from 65 to 105 HP - emits 30% less CO2 than an engine of equal performance.


Visitors to the show will admire the first application of this new engines on a 500, the first Fiat model on which it will be introduced next July. The car is equipped with a two-cylinder turbo 85 HP engine which has the lowest CO2 emission levels for a petrol engine (up to 95 g/km) without compromising performance and driving pleasure. Compared with the two engine versions available today, it provides excellent performance with a major fuel reduction: the new turbo two-cylinder 85 HP engine consumes down to 15% less fuel and has 25% more performance than the 1.2 8v, while fuel consumption drops to a remarkable 30% with respect to the 1.4 16v with comparable performance and the same high driving pleasure.


Furthermore, with respect to a four-cylinder of equal performance and medium displacement, the new engine is significantly shorter (-23%) and lighter (-10%), opening the way to interesting further developments, such as methane fuel feed or hybrid technology combinations, again under the sign of greater eco-friendliness. In particular, a methane version of the TWIN-AIR will be available soon providing a further CO2 emission reduction: this is possible by adopting a pair of special injectors in addition to the petrol injectors on the intake manifold rails. Improving these fuel saving results using internal combustion engines will be difficult and alternative technologies will need to be developed. The combination of traditional engines and electric motors appears particularly promising. Precisely because of its small size, the TWIN-AIR is well suited to be coupled with an electric motor, and in general with a device arranged between engine and gearbox for recovering and storing the energy which is normally wasted during braking.


Nothing short of an engineering gem, the two-cylinder implements the revolutionary Multiair technology developed and patented by FPT - Fiat Powertrain Technologies, which was introduced on FIRE engines last year for the first time. The heart of Multiair is a new electro-hydraulic valve management system that reduces fuel consumption by controlling air directly via the inlet valves (without using the throttle). Multiair reduces polluting emissions (thanks to improved combustion control) and also considerably improves performance by boosting driveability with respect to a traditional petrol engine of equal displacement.


Furthermore, the new TWIN-AIR engine takes the concept of downsizing to the extreme: combining a small displacement engine with a next-generation turbocharger provides performance comparable to - or even better than - that of a larger engine but with less fuel consumption and lower emissions. And more: the turbo significantly increases the maximum torque, making it available at a very low rpm, with the result of offering greater flexibility and an unrivalled promptness of response compared to conventional aspirated engines. All this comes with a simple build that benefits strength and reliability.


Last but not least, the new engine was painstakingly optimised and tuned. For instance, the basic two-cylinder architecture - combined with the low friction of internal parts - ranks this engine best in the "friction" class in the world. Furthermore, computer simulations have been used to identify the best possible standard displacement in terms of thermo-dynamic efficiency, and the best fluid dynamic configuration to optimise and get the best out of the MultiAir system. Finally, special attention has been placed on the NVH (Noise, vibration, and harshness) aspect to ensure vibration performance at least equivalent to that of a four-cylinder, with equal performance but with a characteristic sound. For this purpose, a balancing countershaft was used to maintain optimal vibration levels in all operating conditions of the engine, from the idling speed to top power.

2011 NEW POLO GTI UNVEILED

2011 Vw Polo GTI

The new Polo GTI has been unveiled, promising to be the fastest, most focussed and cleanest performance Polo yet produced.

The original performance variant of the Polo was unveiled in 1986 in the form of the G40 Coupé - a car that mixed a fast-revving, 113 PS, supercharged engine with a low kerbweight and sharpened responses.

Fast forward 24 years and the new Polo GTI bears similarities with the G40. At its heart is a 1.4-litre TSI engine that uses a supercharger from idle through to 3,000 rpm at which point the turbocharger cuts in to provide boost. The result is an output of 180 PS at 6,200 rpm and 184 lbs ft of torque from 2,000 rpm which, when aligned with a 1,184 kg kerbweight, allows the Polo GTI to accelerate from rest to 62 mph in 6.9 seconds before reaching a top speed of 142 mph.

Despite a keen focus on performance, the new Polo GTI is capable of delivering 47 mpg on the combined cycle while emitting just 139 g/km of CO2.

The TSI engine is linked to a compact seven-speed, twin-clutch DSG gearbox that channels drive through the front axle. In addition, the Polo GTI is fitted with the XDS differential, an electronic cross-axle traction control system for improved traction and handling. The XDS system is a functional extension of the electronic limited slip differential (EDL) which is a part of the standard ESP system.

In order to sharpen responses, the Polo GTI is fitted with new springs and dampers which results in a 15 mm lower ride height than the conventional Polo.

Like its Golf GTI sibling, the Polo GTI features significant aesthetic changes. A new front bumper featuring a deep airdam is joined by a honeycombe grille element with horizontal red strips and a simple GTI badge. New headlight units complete with the option of LED running lights lend the Polo GTI an imposing new look.

Further back, a subtle sill extension wraps around the lower edge of the body while at the back a new rear bumper features a small diffuser and a pair of chrome-tipped exhausts. The Polo badge is replaced by a simple ‘GTI' version.

Finally, a set of 17-inch wheels identical to those fitted to the Golf GTI are fitted along with a set of red brake callipers.

The changes continue inside the Polo GTI with revised dials, a new, flat-bottomed GTI steering wheel complete with small gearshift paddles and contrasting red stitching, aluminium pedals and new, heavily bolstered front sports seats finished in tartan trim. Subtle gloss black trim covers the centre console while the headlining is now finished in black.

The new Polo GTI is due to arrive in the UK in the summer at which point pricing and specification will be announced.
