It’s been really interesting “watching” the development of the C8 Corvette from Concept to Reveal. Of course, we are not quite yet at the reveal stage for the next generation Corvette with still another 44 days to go, so there is still plenty we don’t know about the new car, especially when it comes to major details like info about the mid-engine’s new transmission.
When the first C8 Corvettes prototypes hit the road, it was widely believed that the car would be getting a dual-clutch transmission. As GM doesn’t have its own dual-clutch transmission, various manufacturers were researched with ZF and Tremec believed to be the front runners in supplying of the new gearbox.
Following the reveal of the various options earlier this year after a customer walked into a Canadian dealership and spec’d out a C8 Corvette via GM’s Workbench software, we learned that the car would have just one transmission option – an 8-speed Dual Clutch Transmission. As Tremec doesn’t offer an 8-speed DCT, that left ZF as the sole contender…so we thought.
But thanks to our friend Jeremy Welborn, we now think GM may be building its own Dual Clutch Transmission for the C8 Mid-Engine Corvette after this new patent for an 8-speed DCT was published on June 4th.
Below are several diagrams from the new patent and we’ve included the full Patent Publication for your review as well. Reading the abstract summary from the patent explains the reason for building such a transmission:
While current transmissions achieve their intended purpose, the need for new and improved transmission configurations which exhibit improved performance, especially from the standpoints of efficiency, responsiveness and smoothness and improved packaging, primarily reduced size and weight is essentially constant. Accordingly, there is a need in the art for a transmission having improved packaging while providing desirable gear ratios and torque ranges.
There are several benefits to the dual clutch transmission over the traditional standard and manual transmissions. First and foremost is the lightning fast shifts between gears. The aptly named “dual clutch” allows the transmission to be in gear and is poised to serve up the next gear very quickly with no power lag from the engine between shifts. Dual clutch transmissions are more responsive and the shifts are smoother, and there is also a benefit of improved fuel economy.
