2010 Corvette ZR1's Performance Traction Management System


In addition to the new launch control system coming to all manual transmission Corvettes in 2010, there is another new feature coming exclusively to the Corvette ZR1. Called Performance Traction Management, the system integrates the Selective Ride, Traction Control and Active Handling systems and manages the vehicle's acceleration based on the conditions and driver's selection.




The Corvette Team re-engineered the ride control switch on the center console. The normal mode continues to give you the tour and sport adjustments on the shock absorbers, but switching into Competition Mode then brings up the Performance Traction Management. The ride control switch than illuminates to PTM Traction. Turning the switch then allows the driver to select the Traction mode.
