The choice for the top variant of the Chevrolet Corvette C8 in 2020 does not seem to come with much weight gain. A booklet published on the Corvette Forum shows that the C8 convertible is only 102 pounds heavier than the standard Corvette C8 coupe, which loads 3535 pounds, including liquids. Previously, GM only gave us the dry weight of the C8 Corvette (3,366 pounds). The C8 coupe itself is only slightly heavier than the C7 Corvette Stingray; the long-running C7 we had in our fleet weighed 3,480 pounds. Choosing the Z51
Another interesting detail of the booklet is the quarter mile time of the Chevrolet Corvette C8 of 11.3 seconds at 121 mph. That's just 0.3 seconds slower than the 755-hp C7 Corvette ZR1, which finished a quarter mile in 11.0 seconds. However, the ZR1 was clocked at 131.8 mph when it crossed the finish line, 10.8 mph faster than GM estimates for the 2020 Corvette C8. Other vehicles with which the C8 Corvette meets the quarter mile include the Porsche 911 GT3, 2018 BMW M5 and 2018 Mercedes-AMG GT R. Of course, we will need to check GM numbers when we get the C8 Corvette for testing, but our estimate gives you an idea of what to expect from the new mid-engined car.
Powering the Chevrolet Corvette C8 2020 is a mid-mounted 6.2-liter 490hp V-8. and torque of 465 lb-ft (or 495 hp and 470 lb-ft with the Z51 package). The eight-speed dual clutch automatic system will be the only gearbox available, marking for the first time that the Corvette will not come with manual transmission.
