I have grown to greatly prefer Bentleys (especially the Continental GT) to anything its limey cousin Rolls Royce seems to put out (I think the Phantom is heinous). Now, Bentley is promising to debut their crown jewel, the Extreme (teased above), at the 79th Annual Geneva Motor Show from March 5-15. According to Bentley’s PR:

On March 3rd at the 2009 International Geneva Motor Show, Bentley will reveal its fastest, most powerful production car ever. Delivering supercar performance, this new model is very much the extreme Bentley. Importantly it will run on biofuel, delivering stage one of Bentley’s environmental commitment and pioneering the use of this fuel in the luxury sector.

UPDATE: I love that they’re touting this car’s “environmental commitment“, as their last line averaged 10 mpgs in the city. They promise to “introduce renewable fuels across the entire Bentley range by 2012. The renewable fuel solution will be based around the incorporation of “FlexFuel” powertrains – engines that can use either biofuel or gasoline – into Bentley cars, dramatically cutting CO2  emissions on a well-to-wheel basis.” Well, when you’re driving around a 5500 lb, 552 hp supertanker, I guess you wanna clean up your act as much as possible.
