: After reaching out to Chevy PR for clarification, we now know that the 16/29/20 City/Highway/Combined mile-per-gallon ratings are for the standard Corvette with the new eight-speed transmission, while the 0-60 and quarter-mile times are for the Z51-equipped car using the new trans. The company does not yet have mpg estimates for the Z51/8AT combination.
The Chevrolet Corvette Stingray
is already one of the best performers in its class and price range, and Chevy
is making it even better for the 2015 model year with the introduction of a new, eight-speed automatic to replace the previous six-speed. The updated transmission isn't exactly news
, but the Bowtie brand is finally telling customers why the two extra gears are so important. Autoblog
will have driving impressions of the 2015 up later today, but for now, you can snack on this delicious morsel of info as an amuse-bouche
ahead of our full impressions.
The eight-speed carries an EPA-estimated rating of 29 miles per gallon highway, a 1-mpg improvement over the previous automatic, and the 16-mpg city and 20-mpg combined figures remain the same as before. According to Chevy, part of the improvement comes from a new 2.41 rear axle ratio that has the engine turning 8 percent less at 70 miles per hour. Though, Z51 models keep their 2.73 ratio at the rear.
However, it's not all about eking out slightly better economy, as the eight-speed also makes the Stingray even quicker than before. The gearbox hustles the 2015 'Vette to 60 mph in 3.7 seconds, a tenth better than with six gears. The run through the quarter mile also drops a tenth to 11.9 seconds. The boost in performance comes thanks to a more aggressive first-gear ratio than before, the company claims.
Of course, not everyone wants an automatic, even an improved one, so for those who want to row their own gears, the seven-speed manual is still available too. Scroll down
