Not a factory test. For comparison, Sport Auto did 7:18 with the .2GT3 vs 7:12 Factory.

 

Tyres: Michelin Pilot Sport Cup 2 ZP. Manual gearbox.


----------- Mercedes-Benz AMG GT R - Christian Gebhardt - 7:10.92 - 585 / 1614
Chevrolet Corvette Z06 (C7)(Manual) - Christian Gebhardt - 7:13.90 - 659 / 1609
------------------ Porsche 991.2 GT3 - Christian Gebhardt - 7:18.20 - 500 / 1413
--------------------- Ferrari 488 GTB - Christian Gebhardt - 7:21.63 - 670 / 1535
------------ Porsche 911 Carrera GTS - Christian Gebhardt - 7:23.77 - 450 / 1513

 

Great time. A shame we couldn't see the PDR view.

 

With the release of this video, I quietly hope Chevy will release their official times for the C7Z.

You may recall that Porsche and Sport Auto had both done their tests the same day.

 

Isn't the ZP Cup2 tyre the same one that the AMG used?

 

USA!

 

5 second difference between gts and gt3 on a 7:00 track

that is like les than 1 second on a 1:30 track

so close

 

No.

The AMG tire is specific to the AMG. Apparently it's sticky enough to require tire warmers!

 

Just sold mine a few months ago. What a great car!

 

You know what would be really interesting, not just for the C7, but for any car (GT2 included, as well as the Performante, etc.)

Do 2 laps, and average the times.

I would suggest even 3, but not sure how many cars can actually do more than 2 laps on the 'Ring without running out of gas.

 

That's pretty damn cool, makes the mid-engine C8 an even more interesting car.

 

Does the corvette have auto blip on downshifts? It's interesting to see with this car the driver mainly uses 3rd gear. He definitely shifts way more when driving the GT4, and people said that car had long gears.

 

What's even more interesting is in their 991.2 GT3 run the car has PDK, bucket seat and minimal dash hardware - no media console..... Is it the power difference?

 

It does have 'auto rev matching'. Which can be turned off btw.

Notice he also 'misses' the 2 to 3 upshift a couple of times; (happens to many owners in the M7 version), which obviously cost him some time.

One of the factory drivers probably could have pulled off a 7:10 with the M7, and perhaps even quicker with the A8 version IF it could be kept cool enough for one lap.

As to why GM never released a time; it's an enigma.

Nothing like 600/600++ hp/tq and big *** tires
