Wow, what a disappointment. A lot slower than a Lamborghini Huracan Performante.
Lambo really nailed it with the PERFORMANTE
gt3rs - significantly cheaper than the performante yet only 4 seconds slower
gt2rs - slightly cheaper than the performante and 5 seconds faster
Don't rise to it - he's just trolling
I rather think it's good humoured banter... Made I larf anyway hehe

Great car, stonking engine but its just a tease as they won't sell you one unless your in the click or have had plenty of their uninteresting cars
Yawn. Plenty of people enjoy looking at/reading about cars that they can't buy,

So it’s not a tease then, because they will sell them, to their best customers, who can actually afford to buy and run one.

As I said before, if you pop over to the 911 pages you’ll see dozens of PHers chatting about their very real GT3/3RS/2RS cars and allocations.

Stop being so jealous that it isn’t you (or me)

Very impressive! How long of a straight would it take to reach it's 310km/h top speed? Did that have factory aero as it looked like it would struggle to get to 290 to me
The main straight is slightly uphill, that will blunt the last bits of acceleration to max speed.

Cheat battery? Twisted logic.

Do you feel the same way about forced induction? Or fuel injection?

On the straight at the end of the video (6.30) why is car sitting on the rev limiter at 275kmph in 6th and not changing into 7th?

Döttinge Hohe is actually quite up hill. There’s over 70m of elevation change from the lowest point (at the start of the straight) to the finish.

https://veloviewer.com/segment/5539685

Shifting up would likely shift out of the power band (max power is at 8,250rpm) as 7th is likely to be geared as an overdrive. Furthermore, the engine is also around 500rpm short of the Rev limiter the entire time. The reason is won’t rev any more is simply because the car has reached its vmax in the aero configuration on that gradient.

You've gotta admire talented driving, when you see it.
Hand me over such a car and I will do 9 mins after 5 laps... A very experienced driver might get 8... Only a serious pilot wil approach 7-something...

Only if you've already got a good knowledge of the ring. Never underestimate how difficult even a sub 9min lap is regardless of car.

True.
I've clocked up over 100 laps on that track and I still learn something each time around.

Each car rides the undulations and corners slightly differently, the surface evolves/degrades and from time to time it is renewed in sections providing a constantly evolving surface (not to mention the track temps and weather).
Throw in to the mix that one can approach cars and pass them on various parts of the track that you may not have used on any previous laps.

Its a great challenge which comes from the fact that no two laps are the same.

7th in the gt3 or rs is not an overdrive

OK, but either way, 7th would clearly be too long for Döttinge Hohe as it won't pull the limiter in 6th...

Maybe not an 'overdrive' but maybe just that little bit too long to hit v-max. There are plenty of cars where the top gear isn't the fastest gear, 7th being just that little bit too long to push through the air, the 570s McLaren certainly lists the top speed as being in 6th gear not 7th for example.

My first thought watching this was that it seems geared a little high, and that it could go even quicker with lower gearing.

There were several sections where the car pulled through 5th (relatively) slowly, not quite hitting 6th before the braking zone. Notwithstanding the fractions lost through extra shifts, it seemed like the improved acceleration from shorter gearing would have been beneficial overall, on this circuit at least.

As it is extremely unlikely that my casual observation on gearing is something that one of the most talented development teams around would have overlooked in their relentless pursuit of speed, it got me thinking. Does anyone know if GT3 gearing is compromised for emissions legislation like the 'normal' 911s or are the engineers given free reign?

As an owner of 991.1 GT3 RS I am also trying to figure out where those 24secs gone ?

Do we really have an official time - who was the driver - what tyres did the car have? Track conditions.
Brief search I did - did not show too much.

I can't believe the 991.1 GT3RS is slower than the heavier with less aero GT3 991.2 on same tyres - same conditions - same driver.

Well done to Porsche for this performance. That driver is a nutcase - My God...

Epic performance.

PS: Performante is a faster can than Gen 1 RS - for sure
PS: Think 7th on GT3 is longer than 7th on a GT3 RS (wonder if gearing is the same bettween 991.1 and 991.2)

The car does see to suffer from high speed aero drug.

I think the main answer is tyres....and a bit more power. I believe the new car is on a newer racier compound of the Cup2.

Well. The video is supplied and posted by Porsche themselves and they generally have an independent timekeeper (unlike many). The driver was Kevin Estre (as stated in the article) and the tyres are Cup2 R's (detailed elsewhere on the internet)

All the info I can find says the 991.2 GT3 RS with the Weissach Pack is actually 8kg lighter than the old car. So not sure why you think it's heavier? And as for the aero, I'm pretty sure it's got the higher wing stays of the GT2 RS and I suspect the NACA ducts in the bonnet are there for aero benefit too, so if anything it also has more than the .1.

Why I will never own an RS product - I have no where near the skill needed to extract 25% of that performance.

Glad they are made though... what a driver, what a car.
I honestly think people are a little harsh on themselves. I think the majority of enthusiastic drivers who are prepared to listen and learn can get with 90% of a car's ability....
