Geneva preview: Bentley Continental Supersports Convertible

Confirming earlier reports, Bentley announced a Supersports variant of its Continental Convertible today ahead of its Geneva Motor Show debut. Boasting 621 horsepower, the high-performance ragtop is the fastest four-seat convertible in the world, according to Bentley.

Certainly a toy reserved only for the most elite, the Continental Supersports Convertible is essentially a droptop version of the standard Continental Supersports coupe introduced in 2009.

Under its hood, the convertible gets Bentley's 621-horsepower, 591 lb-ft. of torque twin-turbo W12 capable of running on E85 bioethanol. It uses a beefed up ZF 6HP26 six-speed automatic transmission with Quickshift that slices shift times in half, according to Bentley, and it comes standard with a 40/60 rear-biased all-wheel-drive system. Capable of sprinting to 60 mph in just 3.9 seconds, the Continental Supersports Convertible tops out at an even more phenomenal 202 mph.

All that power is reigned in by carbon-ceramic brakes and a modified stability control system.

Despite significant weight savings measures inside, outside and under the hood, the massive 189.1-inch-long convertible (which also measures 86.4 inches in width between the edge of each mirror) weighs in at 5,279 lbs. Still, Bentley says it was able to cut the standard convertible's weight by using lightweight carbon fiber sport seats and ultralight 20-inch forged alloy wheels - good for a 198 lb. cut compared to the standard GTC Speed.

Inside, the Continental Supersports Convertible essentially mirrors the coupe with special styling touches and a unique carbon fiber trim design. Soft-grip leather and Alcantara are standard throughout.

Bentley has not released pricing or an on-sale date for the North American market.
