2010 Corvette ZR1 Gets Performance Traction Management

Following the rolling out of the 1.5 millionth Corvette and the unveiling of the 2010 Corvette Grand Sport, GM announced yesterday an upgrade for its 2010 ZR, with the addition of the Performance Traction Management (PTM) technology.

The system, part of the new Launch Control feature, is used to optimize traction for greater and more consistent on-track performance thanks to its ability to hold a predetermined engine speed while the driver pushes the throttle to the floor. When full throttle is applied upon exiting a corner, the system automatically manages acceleration dynamics.

Such a feature allows the driver to quickly release the clutch, as PTM modulates engine torque 100 times per second to maximize the available traction. PTM also integrates ZR1's traction control, active handling and selective ride control systems.

To get to the real fun part, we should tell you that the ZR 1 is powered by the LS9 6.2l V8 engine, supercharged by using the sixth generation Eaton supercharger, which helps it develop no less than 638 horsepower and 819 Nm of torque. The LS9 is paired to a close ratio six-speed manual transmission and a twin-disc clutch.

Whereas the ZR1 is built on the same aluminum chassis used for the Corvette Z06 and boasts similar SLA front and rear suspensions, tuning work was done to the SLA to help it match ZR1's wide tires.

As for the prices, according to, the price for the 2010 Corvette ZR1 is some $2,910 more than the one to be paid for the current model. That would put the tweaked ZR1 in the $120,000 range.
