Bentley's biofueled concept car appears ever so briefly in this teaser video. It has the shape of a GTC and sounds thunderous. That's to be expected since Bentley says it will be the most powerful car they've ever made.
The teaser video clip shown on this page depicts a new Bentley which is powered by an engine that uses bio-fuels. According to the marketing video this will be the most powerful Bentley ever built.
From the flashing shots it appears to be based on the GTC body style and the sound it makes is ferocious. A date of March 2009 flashes by within a second on the video so presumably this is when the car will be publicly unveiled. A major International Motor Show in Geneva happens to be scheduled for March too.
Currently the most powerful Bentley is the Continental GTC Speed with makes 600hp (447kW) and 750Nm (553 lb-ft) of torque.
