Is there a delay or something?
Now that the C8 Corvette has finally arrived, it's time to dig into its many details. Chevrolet already announced the C8's new 6.2-liter naturally aspirated V8, called LT2, produces 495 hp and 470 lb-ft of torque and will be paired exclusively to a new eight-speed dual-clutch transmission, but about actual performance times? Okay, so 0-60 mph is expected to happen in less than three seconds when equipped with the optional Z51 Package, but what about top speed? Nothing was mentioned in the press release or at the official launch party.
GM Authority has confirmed the reason why. "We still need to test that," said GM President Mark Reuss at the C8's debut last week.
Chevy engineers have not performed a top speed run yet? We honestly find that hard to believe. No doubt computer simulations have been performed that can also give a strong indicator about what to expect. More than likely, a top speed number does exist but still needs to be confirmed by a production-spec C8 instead of a test mule. Fortunately, we can get a pretty good idea about top speed even before an official announcement. Aside from the V8's horsepower and chosen gearbox, other factors need to be taken into account, specifically weight, tires, and aerodynamic drag. Chevy already stated the C8 has a dry weight of 3,366 pounds.
There's certainly plenty of aero components, such as the rear spoiler and front splitter which produce a combined 400 pounds of downforce. Riding on a set of Michelin Pilot Sport ALS tires while the Z51 package swaps those for Michelin Pilot Sport 4S tires, GM Authority noted the latter is rated at 186+ mph. Lastly, let's look at the C7's top speed numbers, according to each model:
C7 Stingray: 187 mph
Stingray with the Z51 Performance Package: 186 mph
Grand Sport: 181 mph
Z06: 205 mph
ZR1: 212 mph
Given all of the above, expect the C8's top speed to, at the very least, match its "base" model predecessor. Later iterations will probably feature some electrification. Don't be surprised to see future C8s exceed the C7 ZR1's already crazy fast 212 mph.
