The 2014 Corvette Stingray offers performance and technology on par with some of the most advanced sports cars on the market. But in the case of its carried-over 6-speed automatic transmission, it is overshadowed by the quicker shifting and more efficient 7-speed and 8-speed automatics offered by the competition. However that might not be the case for much longer, as a report from Automobile Magazine states an eight-speed automatic is in the works for the new ‘Vette.
The report highlights a technical paper previewed by the Society of Automotive Engineers that details the upcoming eight-speed automatic to be offered in the 2015 Corvette. The new transmission, dubbed 8L90, is said to be roughly the same size as the 6L80 it is replacing.
The 8L90 has a torque capacity of 737 lb-ft of torque and an overall ratio spread of 7.0. Thanks to a shorter first gear ratio, the 8L90 will deliver an improved launch off the line and improved highway fuel mileage due to the wider ratio spread. Considering the Corvette’s already impressive fuel economy figure of 29 mpg when equipped with the seven-speed manual, it seems possible that with an eight-speed transmission highway fuel economy figures could jump past the 30 mpg mark, an incredible feat for a 6.2 liter, 450 horsepower V8 performance car.
The full paper will be available for purchase in April 2014, but hopefully we can dig up a little more info at the 2014 North American International Auto Show in Detroit next month.
Update: SAE has taken down the published paper since word spread.
