patent drawing for a General Motors seven-speed dual-clutch transmission

Although a report last year indicated that the seventh-gen Chevrolet Corvette could be getting an eight-speed automatic transmission, it looks like General Motors might have some other plans in mind. General Motors recently filed a patent with the US Patent and Trademark Office for a new seven-speed dual-clutch transmission, and CorvetteForum.com makes the obvious guess that this performance-enhancing gearbox could find its way a future version of Chevy's performance coupe.

The drawing above comes directly from the patent filing, and while the gearbox will almost certainly be used in more than just one model, it would be a welcomed replacement for the six-speed automatic currently found in the 2014 Corvette. The idea of a DCT in the already-impressive C7 Stingray definitely makes the rivalry between the Corvette and the Porsche 911 a little more intriguing.
