Corvette ZR1 returns for 2010 with
new Performance Traction Management (PTM) technology. It is an advanced
system that is part of a new Launch Control feature, which optimizes
traction for greater and more consistent on-track performance. The rumors
are true. The speculation ends. And the UFO sightings on desert highways
were not of extraterrestrial craft – but they were of a low-flying object
capable of seemingly otherworldly performance. Chevrolet officially
announced the 2009 Corvette ZR1 – an American supercar that not only
establishes new benchmarks for production-based power and performance, but
challenges global competitors with a world-beating driving experience that
also comes with a world-beating price of entry.
The PTM system holds a predetermined engine speed while the driver pushes
the throttle to the floor. That allows the driver to quickly release the
clutch and the system modulates engine torque 100 times per second to
maximize the available traction. The system is capable of approaching a
skilled driver's best effort and repeats it consistently.
