With the 2023 Corvette Z06 being tested at the Nurburgring, the forums have been humming about the potential lap time for the new car.
However, the conversations surrounding the next generation Z06 have been off-the-charts in speculation of whether the car is naturally aspirated or if it will be a twin-turbo based on what users are seeing and hearing as they watch the videos of the test cars on the track. FYI, we are firmly in the Naturally Aspirated camp.
One user who has gotten quite a bit of traction over the weekend has stated the Z06 is a twin-turbo with 700+ hp and has the ability to run the quarter-mile in 10.26 @ 135 mph. The belief is that Chevy would not go backwards in horsepower from the C7 Z06’s 650-hp/650 lb-ft torque and therefore the C8 will be as powerful, or even more powerful than the preceding model.
Like I said, lots of speculation…
A member of the Corvette Forum (and MidEngineCorvetteForum.com) named Keagan-Z06 decided to reach out to Jim Mero for his opinion on the subject. Mero is the retired GM Ride and Handling Engineer for the Corvette team who test drove previous generation Corvettes on the famous German track. Here is his reply:
Hey there Keagan,
So, taking into consideration several things:
The first and foremost new tires, I know that Lee Willard is a tire design genius. Whatever cup tires are on the C8 Z06, comparing them to the Cup 2 tires that were designed and developed by Lee and myself in 2013, seven years of tire design and advanced technology should result in an incredible tire for the C8 Z06. I would venture to estimate a lap time improvement of 8 to 10 seconds just based on tires.
The second would be the DCT. More available gears to keep the horsepower and torque in the peak power band throughout the lap and lightning quick shifts. Better and more advanced performance traction algorithms. I did not use performance traction for every fast lap I did through the C7 Z06. I did embrace it on the C7 ZR1, having to do it over, I might’ve run the ZR1 the same way I ran everything else.
I don’t know the horsepower of the new Z06 but keeping up with the horsepower gain throughout the generations, I see no reason to C8 Z06 would be any different.
And of course, the driver. I do not know if they are going to have Oliver Gavin drive again. But now there is an engineer on the Corvette I feel would be just as fast, if not faster. His name is Bill Wise, he drove the 7:16 Camaro ZL1 1LE a few years ago.
Summing it all up, based on my armchair analysis, which actually has been pretty good in the past, I see no reason the car shouldn’t be 12 to 14 seconds faster than the 7:10 I ran in the C7 Z06.
The opportunity to have the Corvette be the first American car under seven minutes would be a significant achievement. I know, I’ve been there…….
Thank you, Jim
Mero nearly became the first to drive an American car under the 7-minute mark with the 2019 Corvette ZR1’s 7:04 time and so he is the recognized expert on the subject. However, the unknown element in the conversation continues to be the Z06’s performance numbers which we’ll have to wait until the official reveal date on October 26th to know for certain.
