2015 Chevrolet Corvette Stingray To Feature Optional Eight-Speed Automatic Transmission


Just the Facts:
  • The 2015 Chevrolet Corvette Stingray will feature an optional eight-speed paddle-shift automatic transmission when it arrives at dealerships in August.
  • A Chevrolet spokesman told Edmunds that the upgraded transmission is not expected to cost significantly more than the 2014 Corvette Stingray with a six-speed automatic transmission.
  • The eight-speed automatic transmission is expected to "contribute up to 5-percent greater (fuel) efficiency," said GM in a statement on Monday.

DETROIT — The 2015 Chevrolet Corvette Stingray will feature an optional eight-speed paddle-shift automatic transmission when it arrives at dealerships in August.

Monte Doran, a Chevrolet spokesman, told Edmunds that the upgraded transmission is not expected to cost significantly more than the 2014 Corvette Stingray with a six-speed automatic transmission. Pricing on the 2015 Corvette Stingray will be announced closer to the launch date.

"The ultimate goal was to create a true high-performance transmission," Doran said in a phone conversation on Monday.

The eight-speed automatic transmission is expected to "contribute up to 5-percent greater (fuel) efficiency," said GM in a statement.

"EPA fuel-economy test results are pending and will be announced later," GM said.

The 2014 Corvette Stingray with a 6.2-liter V8 engine and a six-speed automatic transmission returns 16 mpg in city driving and 28 mpg on the highway, according to the EPA. The 2015 Corvette Stingray with the eight-speed automatic transmission should get a roughly 1 mpg improvement in both categories.

 A seven-speed manual transmission will be standard on the 2015 Corvette Stingray.

"The available 8L90 transmission is based on the same eight-speed automatic that will be offered on the supercharged 2015 Corvette Z06, but with unique clutch and torque converter specifications matched to the torque capacity of the Stingray's LT1 6.2-liter naturally aspirated engine," GM said.

The new eight-speed automatic, which is built at GM's Toledo, Ohio plant, fits into the same space as the previous six-speed automatic. In addition, extensive use of aluminum and magnesium make it more than 8 pounds lighter than the six-speed, according to the automaker.

The 2014 SRT Viper, the chief domestic rival to the Corvette Stingray, is equipped with a standard Tremec six-speed manual transmission.

Edmunds says: The 2015 Chevrolet Corvette Stingray will stand apart from much of the competition by offering car shoppers the choice of a conventional manual transmission or an eight-speed automatic transmission.
