Chevy Camaro ZL1 Phase Two: Launch Control
Exclusive Performance Traction Management for the race course, and the drag strip
The Camaro ZL1 will also offer Performance Traction Management (PTM) as standard equipment, which is exclusive to General Motors. First introduced on the Corvette ZR1, PTM is an advanced system that integrates magnetic ride control, launch control, traction control and electronic stability control, to enhance performance on the racetrack and drag strip.
For example, the launch control feature (manual transmission only) automatically modulates engine torque for the best possible acceleration without excessive wheel spin. When the driver pushes the throttle to the floor, the system holds a predetermined engine speed until the driver releases the clutch. Then, 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.
Similarly, on a road course, the driver can apply full throttle when exiting a corner and PTM will automatically manage acceleration dynamics to maximize exit speed based on available traction.
Five PTM performance levels or modes are available to accommodate the given ambient and track conditions, driver experience/vehicle familiarity and driver comfort levels. They include:
- Mode 1 – Traction control set for wet conditions, with stability control on and Magnetic Ride Control set on Tour.
- Mode 2 – Traction control set for dry conditions, with stability control on and Magnetic Ride Control set on Tour.
- Mode 3 – Traction control set on Sport 1, with stability control on and Magnetic Ride Control set on Sport.
- Mode 4 – Traction control set on Sport 2, with stability control off and Magnetic Ride Control set on Sport.
- Mode 5 – Traction control set on Race, with stability control off and Magnetic Ride Control set on Track. Launch control tuned for VHT-prepped drag strips.
“Like the Magnetic Ride Control, the Performance Traction Management system improves the ZL1 experience as a daily driver and on the track,” said Oppenheiser. “By offering five distinct modes of traction management, the driver can select what’s best for them based on their experience and the driving conditions. As a result, novice drivers will find the ZL1 is very enjoyable to drive, while expert drivers will find PTM supplements their driving skill without interfering with their intentions.”
