8 Speed Auto Transmission detailed for 2015 Corvette Stingray

There have been lots and lots of rumors regarding the 8 Speed AT for the 2015 Stingray. Well it’s finally out in the open.

This bad boy is set to replace the current 6 Speed AT that is currently on offer alongside the 7 Speed MT. The new unit is lighter by 4 Kg and is said to be 5% more efficient, the weight savings are due to the usage of magnesium along with lightweight aluminium.

Chevrolet’s assistant chief engineer for 8 speed automatic transmissions said, “Corvette Stingray’s new eight-speed automatic delivers the comfort and driveability of a true automatic transmission, as well as lightning-fast shifts and the manual control that enhance the performance-driving experience.


This new AT happens to be a single clutch model and not a dual clutch option, but Chevy claims that claims that it actually provides faster upshifts than the PDK transmission from a Porsche 911.

It was designed to enhance the driving experience of the Corvette Stingray and offer a level of performance equivalent to a DCT but without the hassle of R&D.

Pricing details haven’t been released yet about the next gen “Vettes” equipped with these gearboxes expect details as we approach the New York Auto Show 2014.
