Thanks to comparatively small plates, the twin-disc system enables similar disc inertia to the Corvette Z06, which has a 290mm, single-disc system, contributing to low shift effort and providing exceptionally smooth engagement and light pedal effort. In fact, the more powerful ZR1 has a pedal effort similar to the Z06.
ZR1-specific gearing in the transmission provides a steep First-gear ratio that helps launch the car. The car's top speed is achieved in Sixth gear-a change from the Fifth-gear, top-speed run-outs in the manual-transmission Corvette and Corvette Z06. The gears also are designed to balance performance with refinement. The angles of the gear teeth are optimized to provide both strength and quietness.
Editor's Note: The word is now out on the baddest Corvette ever to come down the pike. While all the aforementioned info is direct from GM as of December 20, 2007, we will have to wait our turn for one to be delivered to us so we can experience this animal for ourselves. Quite possibly, we will get the call to test it on a real race track as we did for the release of the C6 Z06, which for all intents and purposes would be the safest route for everyone involved. Stay tuned for further developments as they happen. We can hardly wait!
