A year ago at the Geneva Motor Show, Bentley took its first tentative step toward being ever-so-slightly greener with the introduction of the Continental Supersports coupe. The Supersports was a lightweight, higher-powered version of the Continental GT that was the first in the range to offer flex-fuel E85 compatibility. After several months on the market now, Bentley is adding a convertible version of the Supersports next week in Geneva.
Bentley has also announced that, as of this June, all Continental models in all markets will get flex-fuel capability as standard equipment. Like other automakers, the flex-fuel capability includes a fuel sensor to detect the E85 concentration and adjust the engine mapping on the fly. Bentley claims a CO2 reduction of up 70 percent well to wheel (depending on the type of feedstock used to produce the ethanol).
The 621 horsepower twin-turbo W12 can push the Supersports convertible to 60 mph in just 3.9 seconds. Like the coupe introduced last year, the convertible has gone on a diet, yielding a savings of 198 pounds compared to a Continental GTC Speed
