2010 Mini Roadster Concept uses a 1.6-liter turbo-four from the Mini Cooper S. Actually, Mini only goes so far as to say the Roadster "might possibly be powered by" such an engine, but we think it's a safe bet to expect the Cooper S powerplant.The roadster there are only two seats and not a whole lot of cargo space. Thankfully the full 8.8 cubit feet of cargo space is available with the top up or down. so..this car is flexible car and luxury car.
