The performance-oriented version of the Continental GT, the 2012 Bentley Continental Supersports is a luxury supercar available in coupe, soft-top convertible, and a limited edition convertible ISR model. The base models are powered by the same 6.0-liter twin-turbocharged W12 engine, producing 621 hp and 590 lb-ft of torque, for a 0-60 time under 4 seconds (3.7 for the coupe/3.9 for the convertible) and top speed in excess of 200 mph. An air suspension with continuous damping control offers a silky smooth ride. A 6-speed automatic transmission paired with AWD enables the Supersports to achieve an EPA estimated 11 mpg city and 24 mpg highway, for a combined average of 17 mpg. Features include bi-xenon headlamps, vertical front air intakes, 20-inch wheels, dual exhaust, LED tail lamps, navigation, premium leather, keyless-entry and ignition, and carbon fiber sport seats. The ISR offers even more performance tweaks to the W12 engine making it capable of 631 hp. Safety is comprised of advanced airbag system, traction control, stability control, vehicle stability assist, anti-lock braking, and tire pressure monitoring. The Continental Supersports is backed by a 3-year/unlimited-mile warranty.
