The 2011 Bentley Continental Supersports Convertible is the soft-top sibling to the marque's latest coupe, packing the same twin-turbocharged 6.0-liter W12 as the hard-top and putting out 621 horsepower and 590 pound-feet of torque. Also like the fixed roof variant, the Supersports Convertible can run on either gasoline or E85, returning a 0-60 mph run of 3.9 seconds and a top speed on 202 mph no matter what fuel you choose to top up with.
