2010 Corvette ZR1

Aside from the PTM, the 2010 Chevrolet Corvette ZR1 is essentially the same ZR1 that's been around since its introduction in late 2008. Same supercharged LS9 power plant which produces 638 horsepower and 604 pound-feet of torque, same six-speed manual transmission, same carbon-ceramic brakes.
And these features bring the same value and speed to the table now that they did then, only their abilities are now enhanced by PTM. Even the massive 285/30ZR19 front and 335/25ZR20 rear Michelin Pilot Sport tires feel stickier when using PTM.
Thanks to the magnetorheological dampers of the ZR1's Magnetic Selective Ride Control, a supple ride is probably the ZR1's most attractive feature in everyday use. This smart, self-adjusting damping control allows the car to be driven daily as easily as it sets lap records.
