The most extreme Bentley ever
The car, which will be revealed at the Geneva motor show in March, is based on the Continental GT.
The 'extreme Bentley' runs on bio ethanol and is said to deliver 'supercar performance'.
Bentley engineers are using the car as the first part of the company's plan to become a leader in the use of bio ethanol technology within the luxury market.
The company is also working on making the Arnage's 6.75-litre V8 engine run on the same fuel.
