Inside Line: C7 Corvette to be Offered with a 7-Speed Manual Gearbox

It seems like every time we turn around, some other site has an “inside source” that is spilling the beans on the next-generation Corvette. We’ve heard rumors and speculation that the 2014 Corvette will be powered by a turbo, or that it will be mid-engined, or it will have all-wheel drive. Whatever the case, it appears that everyone is talking within the C7 program as yet another “inside source” has come forward to leak new details on the development of the C7.

The latest rumor comes from whose “trusted source” is telling them that the 2014 C7 Corvette will be available in a seven-speed manual transmission.

Having that additional gear could be seen as a way to increase fuel-efficiency as an overdrive gear, but it might also allow Chevy engineers to tighten up the lower gears for improved performance.

In addition to the transmission, Inside Line’s source is saying that the upcoming GEN-V small block V8 that will power the new Corvette will continue with the 16-valve pushrod architecture and will see the addition of fuel-saving technologies like direct injection and a variable valve lift system.

The addition of a seven-speed transmission for the Corvette comes on the heals of the announcement from Porsche earlier this month that it will offer a seven-speed manual gearbox and a seven-speed dual-clutch automated manual transmission on the 2012 911.

Transmission rumors for the C7 Corvette date back to October 2007 when the details of the GM-UAW agreement listed upcoming projects at all the GM factories. One in particular was this from the Toledo, OH transmission plant which read “RWD DCT for NG Corvette will be allocated (2012)”. The DCT typically refers to the dual clutch transmissions and 2012 was the previously the expected model year that the C7 would debut.
