Adding more gears is one way automakers are combating the fuel economy war, and Chevrolet is making strides with the new Corvette.
Starting in the 2015 model year, all automatic-transmission Corvettes are fitted with an eight-speed unit that has pushed the highway fuel economy up by 1 mpg to sit at 29. That is an improvement of 3.5 percent over the outgoing six speed. For 2016 models, Chevy is assuring that the highway fuel economy will improve to at least 30 mpg.
It isn’t just fuel economy that’s better either, with the car’s 0 to 60 mph speed slightly improving to 3.7 seconds.

The new transmission is actually eight pounds lighter than the outgoing model, and is produced in house at GM’s Toledo, Ohio plant. Later this year, the eight-speed will also begin going into the Chevy Silverado and GMC Sierra equipped with a 6.2-liter V8.
