2010 Chevrolet Corvette ZR1

The problem with performance cars that make a ton of power is the ability of putting it down to the road. Normally a well trained driver can handle a car with 500 plus horsepower on the road, but thanks to traction control that limits the power in certain situations, anybody can enjoy a performance car.

Inside Line has just reviewed a 2010 Chevrolet Corvette ZR-1 equipped with an all new traction control that is being called Performance Traction Management (PTM.) The system combines the traction control, active handling, and launch control all under one setting system. There are also five levels of adjustment, from the wet-road condition PTM1, to turning the active handling off with PTM5.

The results are quite good when the system is in use. While the lateral-g numbers are reduced to 1.02 g to just 1, the slalom speed increased by 1 mph from 71.8 to 72.8. The 0-60 time takes 4.0 seconds and thanks to the PTM, anybody can pull that number off.

At the track or going around turns, the PTM allowed the drivers of Inside Line to forgo throttle control and instead kept their feet floored and let the system do all the work.

In total, the car was amazing without the PTM system installed in the car, but now anybody can drive the 2010 Chevrolet Corvette ZR1 to the limit.
