Saw it on on another forum -

(Edit: Projected) Hockenheimring Short: 1:08,0 min
This is a claim by Porsche itself, published in the latest issue of Sport Auto (04/2013).

1:08,0 min - Porsche 911 GT3 (991)
1:08,3 min - Corvette ZR1 HPP
1:08,4 min - Porsche 911 GT2 RS (997.2)
1:08,6 min - Lamborghini Aventador LP700-4
1:08,7 min - McLaren MP4-12C
1:09,5 min - Porsche 911 GT3 RS 4.0 (997.2)
1:09,6 min - Audi R8 GT
1:09,7 min - Ferrari 458 Italia
1:10,4 min - Porsche 911 Carrera S PDK (991)

Holy **** it's fast on small technical tracks!

Nothing speaks like a lap time.

I'm sorry thats not true. i have the Sport Auto Magazine and the time is not published.
It's unusually snowing in Germany so nothing is happening track wise.
BTW you can get it on your iPad if you read and understand German.

I wonder how to explain the discrepancy? The times listed above are also reported here:

Stop smoking please.

The Dunlop Sport MAXX Race is a vastly faster tire than the MPSC N-Spec. This Dunlop is the main reason the pig C63 lapped Laguna Seca faster than the SLS (by a large margin).

It reminds me of 2007, when people were claiming the new 2007 GT3 being vastly better than the 2004 GT3, and suddenly one day on equal tires, the pace was almost identical.

Cars cannot defeat physics, more weight hurts. PDK helps but not that much on a N/A engine.

On equal tires (your choice for track tire), the 997.2 GT3 RS 3.8 will spank the 991 GT3, you'll see.

Amazing time but I call BS until they are made available for review. Its what it does in the hands of independent pro drivers that counts, not what Porsche claims... Nobody is even close to replicating claimed GTR times at the NBR...

Pretty big claim. The 991 has a faster shifter, more power, better chassis, better tech. The 997 is an older car and has... lower weight. Much as the 991 doesn't excite me and much as I love the .2RS, it will be soundly eclipsed, regardless of tire.

Edit. The 997.1 suffered from PASM. The factory suspension left a LOT to be desired. A fundamental weakness in the car. Doubt Porsche will repeat the mistake.

I could be wrong, but from what I read, 997 was still fundamentally a 996 chassis/platform wise, so big performance improvement in 997.1 vs 996 was probably expecting too much. But on the other hand 991 is chassis wise a big step up from 997, again from what I read n reviews etc, so the car could be fundamentally faster than a 997 even with out the advantage of a faster tire. Also the power gap between 997.2GT3 and 991GT3 is bigger than the one between 996.2GT3 and 997.1 GT3.

AP has stated that every shift is worth .5-.75 car lengths over a manual. He's also stated that the "real" HP for the new GT3 is...last number I heard was 493. So essentially the same as the 4.0 RS.

I think an interesting exercise would be to convert car lengths into avg time saved per shift and then back out a theoretical best Ring lap vs 4.0 RS based on avg number of shifts per lap. I suspect it'll be quite a bit better than what's being quoted, which supports Rad's point that you can't cheat physics.

Carrera GT

Holy greased **** in a t-shirt canon.
Quicker than the robot driving the 12C.
Finally, Porsche robots are faster than McLaren robots.
Victory!

My Fiat has a faster shifter than this 991 wannabe-GT3, is almost 300 lbs lighter, it has an even better chassis, even better tech, and the 3.8 GT3 RS is just a little slower.

The 3.8 GT3 RS is 120+ lbs lighter than the wannabe-GT3, and it big advantage is Aero (on high speed tracks), and a SWB on tight tracks (what makes old 911 so fast on tight tracks).

A sequential transmission is faster, but a good driver on the manual transmission can be nearly as fast.

NJ-GT

I guess Trakcar sent you a stash to smoke it too.

Not remotely the wannabe-GT3 (on equal tires) can touch the MP4-12C.

Come on!

You're arguing that Sport Auto, one of the few respected auto magazines and recognized for their lap time testing, is just plain wrong, and not a little wrong, but wrong by what would require most of a full second over a one minute lap for the 12C to be appreciably faster than the GT3.

If there's the influence of hopium, it's blurring the vision of anyone suggesting the old Ferrari hot rod is in the quick draw in this shoot out.

Anyway, the 430 Scuderia was not tested without Ferrari giving it the steroid treatment and being hand prepped for the media. Let's not revisit the "what it takes to make a Scuderia track well" thread. This is factory cars. How auto

It's just absurd to argue the single plate Scuderia box can change gear to gear quicker than the GT3. There's two gaping holes in the argument. First, nobody (out here in the public) knows the shift time of the GT3, it hasn't been published or even discussed beyond Preuninger making some vague reference to "under 100ms" ... my CVT Prius is under 100ms ... it's continuous ... so is PDK. That brings me to the second point, the GT3 shifts at full power and torque, uninterrupted, with the upshift clutch slipping in additional torque during the engagement transition. The GT3 literally gains on the upshift. The single plate F1 boxes, have to retard the engine during the upshift, so no matter the milliseconds gear to gear, there's the loss of power during the shift.
