That 6 tenths faster than the 918. That's hard to get my head around that. I went to the NYC auto show premier and they stated that computer sims had it lapping the ring in 7:05.

It is fitted with pilot sport cup 2 R and had perfect conditions. That being said, my amateur eye noticed a few mistakes and in a perfect lap it could prob have shaved off another 1-2 seconds (albeit a perfect ring lap is unrealistic even with Schumacher or Hamilton at the wheel)

Also can’t argue with the fact that retesting 918, gt3, .1 RS, etc in these same conditions (perfect weather, freshly paved track) with the same tires (cup 2 R) would prob take up to 10 seconds off their previous lap times.

But the difference is still definitely there and this thing is a monster. Can’t argue with how impressive this machine is and how great this lap was!!

When you're driving at that level... those mistakes don't cost seconds... they cost tenths... and in some cases... you'd have to give up tenths on the entry to make up the tenths on the exit and vice versa.

That was an amazing lap time... he drove it far harder than the .2 GT3 lap... and you could see the confidence that cars grip instills.

Amazing run and amazing lap time... maybe a couple tenths at best... but they'd been testing and lapping for days... I'm super pleased and impressed!

Best Regards,
Dave

fair enough! I agree it’s an insane lap one of the best and hardest driven I’ve seen

true, but the Ring is now faster since they made it safer. If Porsche retested the 918 on the current Ring, it would be faster than the .2 RS.

Still, this was a tremendous lap by both man and machine in the .2 RS.

Well, AP did say that he .2GT3 is a knife and the RS is a scalpel. He cut through those turns and curves as though they didn’t exist. Very little tire squeal.

The lateral high speed steering in this car is over the top. They certainly updated/tweaked the RWS software

Of course the Ring doesn’t punish a road car as much as a GP track would, but this is an incredible achievement from Porsche. Looks like they wanted t prove a point.
+1 Would be great to see real data. Wonder what TBL was???

Lars Kern was present on at least one day of the test (based on pictures).

Lars and Kevin Estre are both VLN / Nurburgring specialists, to an extent. Lars is not a factory driver (for whatever reason, I'm unsure), whereas Kevin is.

The bulk of Porsche's strongest factory drivers IN THE CURRENT 911 RSR were at Long Beach over the weekend - Pilet, Tandy, Bamber. It's possible that one of them or perhaps Richard Lietz could have gone even faster.

In my view, the stiffer suspension setup is evident in the video and Kevin's driving style.

Every OEM also runs sophisticated SIMs at home that get them within fractions of a second of their real world capabilities. Now suddenly they've discovered they don't like it, and basically handed out pre-written articles for people like Jack Baruth to say "yeah man, well we like, totally don't even care about the Ring." Lame.

All I can say is that if you can watch that video and not be excited, you don't have a pulse. Car sounds $(%*&$#@ amazing, driven with ***** of steel. It's just an impressive display of engineering and driving, and that's what you should get out of it. I don't care what is faster or slower - give me the wailing N.A 4.0L please.
It is absolutely the case that GM has smaller budgets for this type of thing than the German OEMs. On a related note, Corvette Racing - per Fehan - does not have the budgetary resources to compete in WEC or field more than two cars at Le Mans (unlike Ford/Multimatic).

Pretty amazed at the time. Most of us will never drive the car at this level but it will be fun trying to get close. I would need to add a private coaching budget along with purchase cost. How to get that past the wife?

Just leave the kool aid for a second and be realistic
Just for clarification. 2017 and newer Z06 no longer overheat on track use, Chevy made plenty of changes in 2017 (for the auto and the manual trans cars), the 2017+ auto still overheats but takes a hot track day to get there, but the manual is fine. Sport Auto tested the 2017 at the Ring (the 7:1x lap time with Gebhardt driving), on good hands the 2017+ Z06 can run under 7:10s, and who knows how much faster it could be on the Cup2R tires that Porsche is giving the two new RS.

Also, there are 5 different tuning for the Magnetic suspension in the C7Z06, the 2016 has different programming than the 2015 (and is faster too), then 2017 got the improvements that were released with the GrandSport, 2018 has new tunes for GS and Z06, and now 2019 has the 2018 suspension tune with temperature compensation (for consistency and improved performance).

The leaf spring suspension is not ideal for the bumpy Nurburgring, but give the C7 a smooth track, and it has no problems chasing Porsche GT cars. My biggest gripe with my Z06, is that without an ECU tune, it doesn't deploy the 650hp until 3rd gear, so at speeds of 93mph or below on a track day (2nd gear goes 93mph), you have a car with less than 600hp with supercharger lag, and a weight penalty. Chevy applied this logic to the new ZR1, but the 755hp are not available until 4th gear.

The C7 GrandSport is the bargain track day car that can chase Porsche GT cars all day long, and just intake, exhaust, tune get the car in the 550hp range, on low fuel is 3,360 lbs. On equal tires as a GT3 RS, my vote goes to the GrandSport, fun, affordable, dependable, and very cheap consumables.

As an armchair spectator, I do agree there were a few mistakes. But, man, that was some fearless driving!

And the PDK was awesome!! Sorry, dudes, couldn't resist

GM has *marketed* the Ring results of a double digit number of cars over the last ~decade. Z06 was intro'd at NAIAS with a Ring track map on the wall behind it. It is what it is.
