Grand Touring has a new definition. Now available as a coupe, a sedan, or a convertible, the 2007 Bentley Continental family is outstanding among Bentleys, today's luxury vehicles, and even today's supercars.A W12 engine employs twin turbos to produce 552 horsepower and 479 ft-lbs of torque at a mere 1,600 rpm. This allows the coupe to rocket to 60 mph in only 4.7 seconds on its way to a 198-mph maximum speed. The GT convertible and the Flying Spur sedan are only slightly slower due to heavier curb weights. The six-speed automatic transmission can be partially controlled with paddle shifters, and it transmits this massive amount of energy to the pavement through all four 275/40R19 inch tires.
