The Chevrolet Corvette Stingray is already a star performer in its class and price range, nonetheless it gets even better in 2015 model with the introduction of eight-speed automatic replacing the six-speed automatic. Not only will it have an improved transmission and acceleration but also a better fuel economy. Conformists will be able to opt for a 7-speed manual.
Although it does not have a double-clutch unit, it is claimed that the 8-speed will shift better than its rivals. With Hydra-Matic 8L90 eight-speed automatic, the 2015 Corvette will be able to accelerate from 0-60mph in just 3.7 seconds and a quarter mile will take 11.9 seconds. This is a 0.1 second improvement in both, all credited to the new gear. The 6.2 Liter LT1 engine is borrowed from the previous model that produces 460hp.
The two additional gears allow it to run at a lower rpm, thus providing an estimated 29 MPG on the highway. Its efficient direct injection system and variable valve timing give it the potential to pass the 30 MPG mark, if handled by a light footed driver. It is a real achievement for a performance oriented machine like Corvette. Its fuel efficiency is even better than Nissan GT-R and Porsche 911.
The car possesses an aluminum frame, a composite body structure and weighs a mere 3,298 lbs. This coupled with its balanced chassis allow it to compete with cars priced much higher.
The car offers a smooth drive both on the street and on the track. The 8-speed’s smooth shift gives a comfortable ride in all eco, sports and tour modes. With a few improvements in the upcoming models, the Corvette Stingray might actually become world’s first car to have a 30 MPG and a 0-60 mph transition in less than 4 seconds.
