According to General Motors in a recent report from the Society of Automotive Engineers, it is that final puzzle piece. GM is confident the 2015 Corvette Z06 8-speed transmission will get 30 mpg. With the current 6-speed, 30 mpg isn't far off and with two extra ratios the 8L90 eight speed transmission improves efficiency by up to 5 percent, which means an EPA-certified 30 mpg highway fuel efficiency rating could be a reality. Plus, the new unit is over eight pounds lighter than the outgoing six-speed, while being equivalent in size. Not to mention, it is capable of shifting 0.8 seconds quicker than the Porsche 911's dual-clutch transmission.
Convinced? The new 8-speed transmission will debut in the 2015 Corvette Z06, but even if a 'Vette isn't in the cards for you, it's possible we may see the standard 2016 model vehicles adopt the new unit!
