I have friends at AMG. Mercedes already knew it was discontinuing the car when they made the record run. It was a swan song to make a point.

To think a GT3RS is faster than a GT2 RS - No way, even comparing the new GT3RS 2023 model to the 2018 GT2RS model.

Porsches are awesome, but let's wait to see what the C8 Platform has in store. We do not know all of the variants of the C8 model yet to compare, nor do we have the times yet (I do not think we will get a Ring time, but we will get VIR and other domestic US track times to compare).
I thought the GT2RS beat the C7 ZR1, maybe I'm missing something?

That was for the Lightning Lap. I was referencing the fastest lap times ever recorded. Jim Mero ran a 2:37.X if I recall, which was better than the GT2 RS (That said, I should have noted that I do think that Jim is a better driver than what The GT2RS had).

Gotcha, both cars are still impressively fast.

They sure did make a point.... to an extend. I know youve seen the lap and they ran on a very wet track. Ive been thinking that in proper conditions this thing will run 6:38.xx. Unfortunately for me Ive no friends at AMG but Ive spoken to 2 dudes with Renntech GTR/GTR Pro and they said they heard from someone that if and when Porsche beats the record they will go back @ proper conditions and take it back. But like I said Ive no buddies over there so Ive no idea if that is true or not so I cant confirm it. Or perhaps it doesnt matter anymore since Porsche couldnt do it with 1,100 lbs more downforce and 400 lbs less weight?

GT3 RS
6:44.8 in 20.6 km
6:49.3 in 20.8 km

All official GM times are in the short length 20.6 Km so ZR1 is almost 20 seconds behind which is huge



Note: Porsche is using Nürburgring for developments and their drivers have thousands of laps in the track. Even if the Z06 is capable to match Porsche times in paper, they cannot do it in reality. I am more interested to see magazine comparison tests in the same time, same driver, same condition.

The way how Porsche's carry speed into and out of turns almost causes cognitive dissonance. As much as I would love to see the C8 Z07 play in the same league as this car, I think we are going to have to wait for more powerful versions--which is a shame, really. Because it certainly isn't apples to apples anymore at that rate. How far does the horsepower and torque advantage have to be in the Corvettes favor?

All the corvette needs to do is shed about 500Lbs. Power isn't the problem, it's portliness is.

Oh for sure. But we know they aren't going to put these cars on a diet so, power it is.

2:37.2, but within a second I feel like is splitting hairs with driver and conditions as the cars are close to being equal except for tires.

Depends on how long the straights are, in the corners it’ll need more tire to hang with the lighter car with more downforce though then the extra rolling resistance slows it down on the straights…always a trade off

Yeah, it's a tough balance for sure. I don't envy the engineers when they're trying to develop these cars, especially when they have to keep things within tight confines per the accountants and the target demographic. We all know how well Corvette does at IMSA with Porsche when the tables are much more balanced.

I wish you bench racers would stop using Lightning Lap. This is run by journalists on a configuration (Grand) that nobody races on. VIR Full is where it’s at and the C7 ZR1 times are nutso (1:52).

I’d love to see:

1. C8Z Z07 sub 7:00 at the ring
2. C8Z Z07 match ZR1 at VIR Full

I agree with you. I should have referenced this time as well on the VIR Full Course (On stock tires as opposed to the GT2RS on slicks which did put down a faster time). So you know, we do not bench race on the Dirt

To confirm the AMG comeback if needed hearsay it would take a call to the top dog at AMG and my connections do not go that high but I do know Mercedes disagrees with the Ring administrators on the technical semantics of production OEM car and kit car.
Mercedes maintains the Porsche Manthey 991 GT2RS car is a kit car that should join the other Manthey cars in the modified vehicles list and not the production list. This is actually in accordance to the KBA (NHTSA equivalent) classification of cars but Manthey is a very big funds contributor to the ring so..... for the time being the 991 GT2RS Manthey Performance Kit car keeps the title.

In light of this important disagreement, I would wager Mercedes is going to join the others and not play the game.

And the other part to your question on downforce and weight is that my personal experience is that the ring is still a torque and power track more than a downforce and less weight track.

I think there are a couple of drivers that went airborne and then upside down that might disagree with you. I think aerodynamics are very important on that track. Power is important to attain the speeds, but drag and downforce affect the power required to attain and carry speed on the course.

Mercedes AMG is falling off. 4 cylinder in the new C63. Pathetic.

Porsche comes to the USA regularly and sets record laptimes on famous USA roadcourse tracks. Name it Porsche owns the lap record including Pikes Peak. GM must not care as their target audience is a lot older , cruiser oriented, and not as track oriented . If GM builds 3000 to 4000 Z06 cars annually they should sell them all and consider it a win. Z06 will be a fantastic sportscar. Build less than 4000 would be smart for brand exclusivity and since its a special car. Forget the value$ relationship and building 10,000 units per year. Ruins the brand.

Jack up the price and remove 300# build a Z06 GTD PRO and jack the price to $200k plus options and minimum 700hp. Then run the “mother-fer” anf get a 6’ min 45sec laptime with a hired gun Porsche factory driver like Kevin Estre and sit back and sell 1000 units more per year. Bask in glory and build more hardcore cars for the faithful.

Excuses excuses ………..GM can get a fast ring time with Z06Z07 package guaranteed but obviously management is not interested , worried about lawsuits, and not concerned so we are beating a dead horse. As for me ive got over 25 years of road racing experience and Wild Hard core cars like GT4RS and 992 GT3RS excite me and are treasures of engineering dominance and clean innovative design versus other sportscars. I likely would never ever take a GT4RS or a 992 GT3RS out to drivers education road racing again as i might SMASH it up and would likely fix it myself so NO CAR FAX. So its simply a badass hardcore collectors item for me.

You want a German porsche racing driver for all driving duties for a Z06!! Nurgburghring RSR versus Mercedes’ GTR.

Good God you are insufferable. You remind me of Unhandled Exception who has recently taken on a new handle. UE proclaimed that he owned a C7ZR1 and a 991.1 GT3 RS which in his eyes gave him credibilty, and most importantly objectivity. I know you are first and foremost an enthusiast who has owned a bunch of Corvettes, etc. but your enthusiasm for Porsche is almost fanboy-like. I wish I could say it's contagiuos, but you are on a Corvette forum. At least you don't pretend to be objective. Have fun!

I agree. They did fix the hump where the GTR launched itself,. High downforce but the accompanying aero drag really hurt the Viper ACR. It made the advertised 177 mph on the long straight, but that was it - aero drag limited. The high downforce probably helped in a few other areas, but it probably killed the tires... and 177 for the length of that straight cost 2 seconds over a car (GT-2R) reaching 192 mph. That is where the Ring is so tough as it really tests a car's overall capabilities - high and low speed on- and off-camber corners, braking, and speed. If a car has a weakness, the Ring will probably find it. I get a kick out of watching the 2012 C6Z/Carbon running a 7:22 with virtually no aero on Cup 1 tires - or the Z-28 in the rain! Limited aero can produce some great results, if you're hung for it.

So it looks like a 6:44 would be a good time?
