We are currently seeing an expansion on the gears of the new transmissions – especially the automatic ones. While Porsche even offers a manual transmission with 7 speeds, the 2015 Corvette will trade a 6-speed for an 8-speed automatic.
While it doesn’t best Chrysler’s new 9-speed automatic transmission, the new 8L90 automatic is a serious improvement for the US sports car in crucial departments – like speed and quality. The upgraded transmission also brings a 5% improvement on the already very good average economy figure – the 460 hp supercar can manage an EPA rating of 30 mpg (7.84 l/100 km) on highway cruising.
“Corvette Stingray’s new eight-speed automatic delivers the comfort and drivability of a true automatic transmission, as well as lightning-fast shifts and the manual control that enhance the performance-driving experience,” said Bill Goodrich, assistant chief engineer for eight-speed automatic transmissions. “It was designed to enhance the Stingray’s driving experience, with performance on par with dual-clutch designs, but without sacrificing refinement.”
Project leader of the C7 Corvette, Tadge Juechter and members of the team have promised timely updates of the generation – and the new automatic is a good one for the second year of the car’s run. Next to the already announced convertible version, in 2015 the Corvette will also sport the higher-performance model Z06, while reports say the range-topping ZR1 version is already in the works.
