Evo's non Ring track times put the two cars within 2 tenths of second.
please pass the kool aid...

I am wondering how much better .2 GT3 time would be over the .1GT3RS if GT3 was dressed up with same tire size. Another 2-3sec?

I would agree...to me it's simply odd to see such a quantum leap with the stated specs of the cars being reasonably close. I would like to see this repeated or see the same driver under reasonably similar conditions run with a .1, .2 and RS with verified dyno outputs and equivalent tires.

The engineer in me would like to see the data or design/tuning parameters explained that have yielded such a large improvement. Hard to interpret or analyze anything with little detail and a one test experiment.

will be interesting to see dyno outputs... once again, hard to know for sure with so many interceding variables not controlled as to what is driving lap time differentials

Lars Kern is as I understand since last year new Porsche development driver. Taking Timo Klucks jobb since then.
I am not surpised this car is fast, also as others also mention nur is a faster track today. Very much the fast flugplatz-swedenX section as Grants picture show. Lars also drove the slightly tuned(not engine, only camber, tire, KW etc) by manthey tuned GT4 10 sec. faster than Porsche stock factory GT4 time.

The vanila 991 gen2 GTS was it not lappning 7.22 min in Porsche factory hands. Thats 2 seconds shy on 991 RS. Mind you 991 RS had a few damp areas on track when Timo Kluck set 7.20min lap.

Oh, MB AMG GT-R is way faster than this new GT3. Remember its 7.11 lap was no factory lap, Hence Mercedes use sport autos lap time from Christian G to market their car. Quit bold and I must say fair! For sure the MB factory got way faster laptime in the car than the 7.11 sport auto time. But to my knowledge they never let any time out.

I guess the manual GT3 will be 5-8 seconds slower than PDK on nur. Nothing but a blunt guess.

I am waiting for this car but no luck yet, I guess 2018 then..

Yes, very optimal conditions. And thats not luck, all factory know fastest laps are in these conditions. Mind you sport auto test on 991 RS was worst ever, it was 30+ degrees. Same when Sport auto did M4 GTS lap, 30+.

Then again factory also only do one lap on the tire. And they keep doing that to they get a fast lap.

Sport auto not like that, thats why MB Amg GT-R LAP at 7.11min is the real world test and cool of MB to let that market their car and not the factory time like Porsche and others use.

@Nur93 -How much faster do you think the ring is now compared to pre-changes?

Oh and I hope you get an allocation.. looking forward to your lap videos,

Where is that 'Oh no, not this **** again' meme when ya need it...

FFS, that Manthey car was not a near stock GT4 with a few tweaks. It had over $10k of aftermarket suspension and other parts, that easily accounted for the time delta.

And I don't know Lars from a hole in the wall, but I'd be shocked if there is a driver on the planet that could run the Ring in a Porsche materially quicker than Timo Kluck. His Ring times are typically faster than anyone else in the same car. Nobody's taking the same car and knocking 10 seconds off Timo Kluck's best time.

You forgot to mention that the .2 GT3 driver was on a strict diet losing 20 pounds and took a big dump that morning while the .1 GT3 driver was force fed a huge breakfast.

That was a grave miss on my part. I appreciate the correction.

I remember reading a Danish fly fishing blog that mentioned the above information was noted in the May edition of Architectural Digest. Or maybe it was Shape magazine... Anyway... Apparently it was a pancake breakfast... whipped cream and a side of bacon. Heavy, thick-cut bacon. The grease also affected his grip on the wheel and the gluten dulled his reactions. He didn't stand a chance...

But more importantly, is it worth you testing this theory for the 991.2GT3 on the Ring this year? I hear autumn is lovely.

Exactly. Because Porsche. I've always respected their engineering, but damn, their marketing/product strategy dept is even more impressive.

911 GTS was turning a 7:26, wasn't it? Also, where is the extra horsepower coming from in the MB? Those two points aside, I agree with you that it would help for MB to have a professional take the car around to find out what the real time was.

I'm still looking to hear anyone's thoughts on the difference in time the repaving gives. I wouldn't go so far as to say this is like a reconfigured track but it certainly makes the times apples to oranges.

It will be interesting if they don't get a similarly spectacular time with the RS.2

The tough part is once they go faster, and the leap is huge like this time, they can't undo it... and they always have to outdo themselves.

It's quite likely though that with the new ring layout being faster, that we'll see similarly huge leaps with other brands.. as an example, look at the Lamborghini Performante time handily beating the 918...

EVO also got .2 to run impressive time at Angelsey track. Seems like lots of improvements so looking forward to tracking it.
