"The fact is, however, that the silver Z06 hand-switch with the Michigan factory-number label on the north loop worked without thermic problems during the last super-start test"

I believe what I see in SA onboard video. At the end of DH Z06 has 277 km/h (my old Porsche GT3 997 had the same max speed at this point with 250 hp less) and GT-R with 100 hp less goes 20 km/h faster. So 0.52 with aero settings set for max downforce sounds reasonable. I'm sure if you remove rear spoiler or put it in minimum settings max speed goes up, but you loose grip and stability at the rest of the track . You have to pay for downforce with max speed.

Highlights:
Engine note evokes emotion
Excellent steering feel translating into excellent road feel
A8 subject to problems on road courses due to lack of 2nd radiator, with reference to forum reports
Adjustable steering feel better in other modes on certain portions of track as track mode is too sensitive
Excellent mechanical grip; i.e. chassis and excellent tires (cup) but window of opportunity for max grip is narrow
Didn't care for M7 but in relation to what? Another manual or compared to automated manual; i.e. AMG GT R? Probably latter. This was predictable as driver missed a few shifts
Stage 3 aero produced amazing grip but cost it 3 seconds. Adversely, without the aero it could have gone faster in the straights, but less quick in the corners, thereby equalizing the two....probably not
Overall I'd say the reviewer gave it an enthusiastic thumbs up!

I used to believe what I see too but then Porsche brought in segmented times (OK a soap box of mine.. :-) but now I do trust and VERIFY..

Thank you for pointing out to the video.. and going back to the nature of my first post and the reported 0.52 CD and 275 on auto motor sport...I still don't buy it (video and all)

So here is the thing.. the Galgenkopf - Dottinger Hohe is about a mile stretch and is a WOT stretch (as you and I know..) and I know the Z06 Aero 3 runs the mile at about 280 from ZERO! What was the driver doing with that mile starting at 190!?? There is a reference to tall gears problems... but I say driver!

Sure...the are other factors..Z06 may have had full wind against and gearing and GT-R full wind on tail (Mercedes lives in the nurb..) but then you cannot compare...

Now.. Camaro Zl1 (same engine) with wing and 160 more kilos and 0.38-0.40+ CD yes..about 275ish..

But Z06 07 aero 3 (top speed 300-ish).. 275 vs 295.. not buying it and then it is easy from there to understand that aero 3 is not a 0.52 tax.. so I stck with Tadge at 0.37

Good chat!

Missing ingredient?

(They removed the rear spoiler too!)

The Viper managed 175 of its 177 MPH there.

All he had to do was floor it there, the driver didn't drive scared! He lacked smoothness, hence, the 7:10 time probability.

The SC Vette was hot and pulling power by consensus, and Expectation!

Mercedes are generally pretty ugly cars with that dumb looking logo in the grill and just about everywhere else on their cars. This thing however
is aggressively ugly. YUK.

Wow! I think they're going hyperspeed the whole way this time!

Not every one, just every automatic and some manuals when they are tracked hard as intended

Sad thing is the new ZL1 with an auto made it all the way around with no issues. Maybe team Camaro can help the Corvette guys finally figure it out

Re the Viper:
After two-and-a-half weeks of practice and testing, with two professional drivers and two GTS-R Commemorative edition Vipers with the huge wing, and GoFundMe funding, they managed to get a 7:03:45 on July 26th.

That still leaves me pretty impressed with the time for the Z06, set during a magazine test.

The Viper:

Looking for a twenty second ZO6 pounding this time!
Enter the new Vette Magic!?

Krisa9977, thanks for the German article. Google translate does some fun things doesn't it?
Like literally translating "Handschalter" into "hand-switch", rather than into what we call a manual transmission.

sunsalem

Agreed.
All things considered, I thought the Viper could do better.

johnglenntwo

The Magic component is only required if a real Gap is indeed finally issued as was expected - At least dispatching the existing ZO6!

That Viper is so sexy.

The times are the times...But I think we can all 'reasonably' assume that both cars (Z06 and ACR-E) can both put down better times. No doubt the ACR-E is a sub 7min car...and no doubt with factory support the Z06 is a likely a sub 7:10 car.

Truth is...none of it really matters...MRLS is just as good as anywhere...if one car is faster than another at MRLS, then 99% chance it's also faster at the ring. Sure there might be one exception here or there...but highly unlikely.

People put WAY too much 'stock' in these times. I'd say the ring is probably one of the toughest tracks in the world to get 'consistent' results at due to the ever changing weather/conditions and factory 'ringers.' So even that makes any comparison tough. There is also no 'official' sanctioning body and who 'really' knows what goes on behind the scenes. 100% convinced there are shenanigans going on with some of these laps. Look at the Nismo time for further proof of this...tons of non-production parts etc.

Thus I stand by my comments from 1-2 years ago...the Ring time doesn't really matter. It's an awesome track...no doubt...epic really. Nothing bad to say about it...but to think there isn't some shady stuff happening with these cars is to be naive. It's more like the McGregor/Mayweather fight to me...LOL. People will watch it...but it's a farce.

The thing about this Viper run is how dangerous it is! Based on our tracks the ACR is a 6:50 car!
The original VID had transient periods of absolute hauling butt, but, doing that the whole way is extreme. You can't let off much because of the all the aero, and there lies their big problem! And add gearing and shifting control!
