Since the GM-UAW agreement became available last week, tons of information usually kept close to the chest has been laid out for all to see and it seems as though a new nugget of information relating to the C7 Corvette is revealed every day. Earlier this week we read about plans to move the Pontiac Solstice and the Saturn Sky to the Bowling Green Assembly Plant sometime after 2011. Yesterday we learned that the C7 Corvette could be offered with a dual-clutch transmission and today’s news? All Wheel Drive!
GM and Sweden’s Haldex already have a performance AWD system dubbed XWD that debuted on the Saab 9-3. The AWD system features an electronic differential and can send up to 85% of torque to an individual wheel to prevent slippage, whether it’s from a fast corner or when trying to put power to the ground.
Various accounts state that engineers have been seen testing a GM prototype with a very wide rear track, which is thought to be a test mule for the next generation Corvette.
We are still five years away from the production of the C7 Corvette and I am already dizzy trying to keep up with the details. If all these rumors are correct, in 2012 you’ll be looking at a kappa-based mid-engine Corvette with all wheel drive and some fancy Shmancy dual-clutch transmission.
Yep, that sounds like a Corvette to me…
Thanks to Wikipedia, I now know what a dual clutch transmission is:
A twin-clutch gearbox or dual clutch transmission (DCT) is a semi-automatic transmission with separate clutches for odd and even gears. The outer clutch drives the odd numbered gears and reverse, while the inner clutch drives the even numbered gears. Shifts can be accomplished without interrupting power, by applying the engine’s torque to one clutch just as the engine’s torque is being disconnected from the other clutch. Since the synchronizers that select an odd gear can be moved while driving the car in an even gear, and vice versa, DCT’s have been configured which shift faster than Formula One cars and other single-clutch AMT’s (automated-manual transmissions, a.k.a. single-clutch semi-automatics); the shift can also be made smoother and more suitable for street-driving than a single-clutch AMT is capable of.
