For the moment, the C8 Corvette is sold exclusively with a naturally-aspirated 6.2-liter V8 engine working alongside an eight-speed Tremec dual-clutch transmission. A rating of 15 mpg city and 27 mpg highway is a good result for Chevrolet and is a touch better than the C7-generation Corvette Stingray that returned 15 mpg city and 25 mpg highway in its final model year.
One of the key reasons why the new mid-engined Corvette is more fuel-efficient than the C7 despite weighing almost 200 lbs (90.7 kg) more is that its LT2 V8 engine features cylinder deactivation which means on highway jaunts, it shuts down four of the cylinders. The C7 Stingray also featured cylinder deactivation but it doesn’t seem to have been as efficient.
Chevrolet has added that the new Corvette can manage 490 miles (788 km) on a single tank of fuel. The ‘Vette’s tank holds 18.6 gallons (70.4-liters).
While the new Corvette is more fuel-efficient than the model replaces, the current Porsche 911 Carrera S is a little more frugal and rated at 20 mpg city and 26 mpg highway. This isn’t a surprise as the 911 features a twin-turbo flat-six compared to the Corvette’s much larger naturally-aspirated V8.
In standard form, the C8 Corvette pumps out 490 hp and 495 lb-ft (671 Nm) of torque while horsepower jumps to 495 with the optional performance exhaust. The car can hit 62 mph (100 km/h) in roughly 3 seconds.
