Deep dive: 2020 Chevrolet Corvette Stingray’s dual-clutch transmission
The 2020 Chevrolet Corvette Stingray is a real supercar filled with many firsts for the nameplate. Chief amongst them, it is a mid-engine automobile.
Nonetheless, it is also the primary Corvette to sport a dual-clutch automated transmission, on this case an Eight-speed. Chevrolet printed a video that takes a better take a look at the thought course of behind the DCT’s growth and why the engineering staff determined the automobile wanted the transmission as an alternative of a standard automated.

Foremost, govt chief engineer of the Corvette, Tadge Juechter, opens the video with a simple clarification: Corvette house owners have requested for one. For many who do not know, a conventional transmission (guide or automated) decelerates the automobile when shifting. It is because the engine is not linked to the wheels in that cut up second. The place a DCT actually shines is in its setup as a result of it avoids this compromise. Consider a DCT as two guide transmissions working robotically with clutches being instructed what to do from computer systems.
Even ahead gears (2, four, 6, and eight) are on one shaft, whereas odd ahead gears (1, three, 5, 7) get their very own. The pc can concurrently disengage one shaft whereas the system tells the transmission to have interaction the opposite. It helps create these lightning-quick shifts and superior sounding snorts when the 2020 Corvette shifts. Ed Piatek, chief Corvette engineer, says within the video a shift takes lower than 100 milliseconds to finish within the new Corvette. The staff additionally discovered they may channel torque by way of each shafts, which means, the transmission is perhaps partaking third, however torque is driving by way of second gear nonetheless. All of this boils all the way down to very aggressive launches and faster Zero-60 mph instances.

This transmission is not an off-the-shelf half, both. The Corvette engineers labored with the chassis staff to design a bespoke transmission able to dealing with every thing deliberate for the eighth-generation automobile. The Corvette makes a variety of energy and torque, and the staff needed zero compromises. Working with the chassis staff additionally helped match the transmission so it helped decrease the middle of gravity within the automobile, and that creates its personal efficiency advantages.
It is best to develop into acquainted with the bespoke DCT within the 2020 Corvette. There won’t be a guide transmission this time round, and that is a sourer first for this iteration of America’s sports activities automobile.
