It was designed with TREMEC to provide the spirited, direct-connected feeling of a manual and the premium driving comfort of an auto- matic, the company noted. A double-paddle de-clutch feature allows the driver to disconnect the clutch by holding both paddles for more manual control.

Engineers set up the DCT with a very low first gear to leverage the additional traction to get the car off the line quickly, and its close-ratio gears 2 through 6 keep the engine near the power peak on track. Tall seventh and eighth gears make for easy long-distance cruising with low mechanical stress and improved fuel economy. The DCT is mated to a new Electronic Transmission Range Selector with no mechanical interface between the shift lever and the transmission. The Corvette's rede- signed electric shifter incorporates two pull toggles for Reverse and Drive and pushbut- tons for Park, Neutral and Low/Manual.

The tunnel-dominant approach offers advantages, according to Chevy, including: Standard-edge red valve covers are a styling touch on the new 6.2-liter small- block V-8 LT2 engine. The next-generation LT2 is paired with Chevrolet's first eight- speed dual-clutch trans- mission, created to improve shift speed and power transfer.
