I won't ruin it with results, but this is an exceptional video, done by EVO in the UK, testing a 991 TTS vs 991 GT3RS on the same track, same driver. Very fun to watch this guy drive, and spot the differences in the cars through the lap.

Of course, I'm willing to bet anything the GT3RS had Cup2 tires while the TTS had PZero. At the very first opening shot of the two cars, the TTS front tire shoulder profile looks PZero to me. If so, the TTS is the faster car.

WOW !!
So a 2017 991.2 Turbo S with Aerokit should be even faster !
Incredible for a car with such good street manners

Yes, this test is a 991.1 TTS vs 991 GT3RS. I'd love to see a rematch with 991.2 wearing Cup2 tires!!

We all knew it, but now we all know it.

The other thing that is striking is that he really had to wrestle that GT3RS round the track, while the TTS seemed more effortless - far less hand movement on the steering wheel.

Those tests have been out quite a while. And yes, the Turbo had PZero tires....I do think the GT3RS would be about a second faster if they were tested on the same day though.

No I dont think so - even Porsches own driver have quoted in interviews that in some cases the Turbo S is faster and in some the GT3 RS. But they said the GT3 RS is the more engaging car - with the TTS all is mostly effort less. But speed wise not much in it.

Porsche even quotes the stock 991.2 TTS lap time at Nordschleife to be faster then the 991.1 RS with PZero tires.

Keep in mind the ring is speed restricted in two segments bc of a crash last yr, so the 7:18 was "digitally remastered" fwiw.

Randyc151

True, but have you ever know Porsche to be aggressive on numbers? Especially in the case of the TTS being faster than their RS?

TT Gasman

I'm very, very impressed with this new TTS.

I wonder what the response would be if the OP had posted this on the 991 GT3/RS forum?

So the GT3RS reason to exist is to be Porsche's track weapon. PDK is chosen because it's the fastest and manual transmission will never been in an RS b/c it's a compromised concession to "driver enjoyment" that sacrifices ultimate track time.

And yet the fat, luxury GT TTS on relatively crap tires is the same speed. So now the GT3RS's existence is justified because "it's more engaging"

And that track seems to be relatively technical. I'm sure the difference would be more pronounced in a higher speed track.

I suppose the RS is more suited to repeated and longer runs at high speed, but I do recall, at the Porsche experience at Barber, the instructors were pounding their TTS's without mercy for hours in 90+ degree weather without any complaint from the car. The irony is interesting.

Well they didn't have much to say, but agree that the TTS is stout.
