But it’s also heavier than its predecessor

The 2020 Chevrolet C8 Corvette is already on its way to dealerships, but GM has yet to reveal all the specs. Although Chevy did announce the car’s top speed, 0 to 60 and quarter mile times remained a mystery. Until today, when a Corvette Forum member got a look at an engineer’s booklet at the 2019 Corvettes at Carlisle event. Fortunately, he also snapped some photos and we now know everything there is to know about the 2020 C8 Corvette.

The 2020 Chevy C8 Corvette is quicker than the C7 Z06

The C8 equipped with the Z51 Performance Package reaches 60 mph in 2.9 seconds

The photos reveal the number we were all anxious to find out: the sprint from 0 to 60 mph. Chevy originally said that the C8 Corvette needs less than three seconds to get there, but we were missing a precise figure. The engineer’s sheet says that the base Stingray hits 60 mph in three seconds, while the C8 equipped with the Z51 Performance Package reaches the same benchmark in 2.9 clicks. For starters, it’s quite impressive that a package with an extra five horsepower and five pound-feet of torque (plus some other upgrades) makes such a big difference.

Second, the C8 Stingray is quicker than the C7-generation Z06. The Z06 has a 0-to-60 mph rating of 2.95 seconds, 0.05 slower than the C8 Corvette. Sure, that’s an incredibly small advantage that might not matter in most environments, but numbers are numbers. What’s more, the C8 Stingray is only 0.05 slower than the mighty C7 ZR1. This means that depending on conditions and the driver, the C8 Corvette could win a race to 60 mph against the outgoing ZR1.

The C8 Stingray needs 11.3 seconds to complete the quarter mile

The sheet also contains info about quarter-mile times, including that it takes the C8 Corvette 11.3 seconds to cross the finish line at 121 mph. That’s a solid 0.7 seconds quicker than the C7 Corvette equipped with the Z51 package. It also crosses the finish line at a two-mph higher speed. At the same time, it’s only 0.3 seconds and six mph slower than the C7 Z51 and only 0.7 seconds and 13 mph slower than the C7 ZR1.

These figures also allow us to do a proper comparison with the Ford GT. Despite having over 600 horsepower on tap, the GT isn’t quicker than the C8 Stingray with the Z51 package, needing the same 2.9 seconds to hit 60 mph. On the flip side, the GT is a half-second quicker on the quarter-mile run.

The 2020 Chevy C8 Corvette is notably heavier than the C7

The sheet also leaked information about the C8’s curb weight and it seems that the new-generation Corvette is significantly heavier. The base model tips the scales at 3,535 pounds, which makes it 188 pounds heavier than the entry-level C7. When equipped with the Z51 package, the Corvette becomes even heavier at 3,577 pounds. That’s 17 pounds more than the C7 Corvette ZR1. The Convertible version weighs 102 pounds more than the coupe, at 3,637 pounds.

Compared to the Ford GT and the Ferrari F8 Tributo, the base C8 Corvette is 181 and 371 pounds heavier, respectively.

The same sheet reveals that the C8 Corvette fitted with the Z51 package needs 108.4 feet to come to a standstill from 60 mph. That’s 1.4 feet more than the C7 Corvette with the Z51 package. The base C8 Stingray, which has smaller brakes, comes to a halt in 115.1 feet.

These figures aren’t official

Some of the figures above may seem spectacular, while other may seem a bit disappointing, but we need to keep in mind that none of them are official. These numbers weren’t supposed to be unveiled to the public so they might be preliminary figures waiting to be finalized through more tests. Tadge Juechter actually mentioned, at the same event where these sheets were leaked, that Chevy still has to do "some additional test work, some final tweaking on the calibrations, and a lot of little fine tuning" until the C8 Corvette goes into production. The official numbers will probably come out in a couple of months, if not sooner.
