The manual and automatic ZL1s are completely different animals. The manual cars get Launch Control (LC). In this mode the clutch is fully depressed, and with the trans in First gear, the gas pedal is put to the carpet. The driver simply has to step off the clutch and hold on. Your brain screams that this is bad idea, but fear not, the computer won’t let the engine scatter. LC works in two ways: first, it predicts the right rpm for the situation (based on things like ambient temp and whether you’re in a “street” or “track” setting in the PTM). It then adjusts the amount of torque to get the car moving with the right amount of slip. As Monte Doran (GM Communications) told us, “they actually found the best times were accomplished with less slip, while on the street they want a little more slip from the tires.” Traction Control works in modes 1-4, but mode 5 is tuned for launching on a VHT-prepped track.
