When the 8-speed automatic was first announced for the 2015 Corvette Stingray, most of us saw the main benefit would be an increase in fuel economy and that has come true as the new paddle-shift auto gets an EPA-estimated 29 MPG on the highway But the new automatic is also faster than than the previous 6-speed with a 0-60 mph time at 3.7 seconds.
It’s not nearly as challenging to build a high-powered car if you don’t have to worry about gas mileage.
But the engineers at Chevrolet do, thanks to government mandates, so they are buckling down and taking it a step further for the upcoming supercharged Corvette Z06, according to a story from Automotive News.
Production is ready to gear up, literally, for the slick new eight-speed transmission that will power some 2015 Corvettes, including the highly anticipated Z06.
GM expects to start building the high-tech automatic gearbox by the end of July, according to Ray Wood, president of United Auto Workers Local 14.
When the 2014 C7 Corvette becomes available next year, it’s widely believed that buyers of the all-new sports car will have their choice of a 7-speed manual or an 8-speed automatic. The new 8-speed automatic transmission will be built at GM’s Toledo, Ohio transmissions plant and is expected to be shared by Corvette, select Cadillacs and other models across the GM lineup. However, in a report yesterday at Motor Trend, sources said the new transmissions won’t be ready for another year, so GM has partnered with the Japanese company Aisin to provide the automatics for C7 Corvette’s first year of production.
