Bentley Continental Supersports

Bentley doesn't have a reputation for environmental consciousness, but it makes a stab in that direction with the Continental Supersports. This flex-fuel car can run ethanol and gasoline blends, without sacrificing performance. A sensor determines if an ethanol blend is being used, and remaps the engine software accordingly, preserving its horsepower figure of 621 and its 590 pound-feet of torque.
