Hint: it beats the C7.
There were many benefits for switching the Corvette to a mid-engine layout, thus ditching the decades-old front-engine design. In order to truly make the Corvette world-class, it required handling and other performance improvements only a mid-engine design could accommodate. Going mid-engine would also make things easier for electrification. But even before that happens (and it will), the C8's new layout design also delivers better fuel economy over its C7 predecessor.
According to Corvette chief engineer Ed Piatek, the 2020 Chevrolet Corvette Stingray will have an official EPA rating of 15/27 mpg city/highway. Not bad for a car powered by an LT2 6.2-liter V8 with 495 horsepower and 470 lb-ft of torque. Piatek also added these figures give the new C8 a driving range of 500 miles.
To compare, the automatic-equipped C7 Stingray (the C8 is automatic-only) delivered the same city-rated fuel economy but on the highway, it was pegged at 25 mpg and could only go 333 miles between fill-ups. Thank its 18.6-gallon fuel tank for that. One way the C8 bests the C7 in fuel economy is its 8-speed dual-clutch which keeps revs low at speed. Another key ingredient is cylinder deactivation.
One of Chevy's main goals for the C8 was for it to be not only an amazing high-performance machine but also an ideal touring car also capable of carrying a couple of sets of golf clubs in the trunk. The slight highway fuel economy improvement and greater time between fill-ups cater nicely to new groups of buyers.
Comparing the C8 Stingray against a couple of competitors, the Porsche 911 Carrera S is rated at 18/24 mpg and the BMW M850i at 18/25 mpg. Obviously, it's too early to know how future C8 variants, such as the next Z06, will deliver on the fuel economy factor, but they should also be quite impressive even with an expected power increase.
Adding an electrification system, either making the C8 a hybrid or plug-in hybrid, opens up all kinds of interesting possibilities.
