Mercedes AMG-GT R

They claim it's on Cup2 and stock... Tires on the side look a bit slick to me. If it is stock though, it just murdered the 488 and 675LT by 10s.

it has an f-duct, mega downforce, and a metric butt load of torque...pretty damn slick technology.

Tyres shown at 0:23 are slick, at 0:25 they are Cup 2s, but why were the slicks even there? I don't for one second believe it's faster than a 488.

Unless you are viewing the video in a hell of a lot better resolution than I am, it is not possible to say whether the tyres shown at 0:23 (lying on the ground) are slicks or treaded. There is certainly not enough information to assert that they are slicks.

love the way the guy just scratches his leg at 38 seconds like he is just driving down the highway.

View it full screen at 0:23 and look immediately right of the car:



However, here's what Sport Auto say.

Again: No slicks or cutted slick-tyres were used for the lap time. AMG will offer two different versions of the Michelin Pilot Sport Cup 2 for the AMG GT R. A normal one, like it is available for the GT S, and a special one for track driving with a more sticky compound. BUT: Both versions of Cup 2 for the AMG GT R are fully street legal! You can compare the sticky Cup 2 for AMG GT R with the Cup 2 for the Corvette Z06. The grip level feels pretty similar!
So again we see the dubious nature of bespoke Cup 2s.

And here we are again with conspiracy theories, and about tires even!

I'm pretty impressed, well done Mercedes!

They were testing the GT3 race car car as well, you can see it fly past the GT R at the 3:15 mark. That car definitely has slicks.

That said, the tires you're looking at are just wrapped to keep them warm. They aren't slick. You can see them here:

I must say that I am far from convinced that that tyre is a slick. I'm not insisting that it is not, but I really don't think there is enough resolution, even in full screen, for one to be confident that it is.

The only thing I would say NB is that the tyre they're resting on you can clearly see has a tread pattern.

But as I think Craigy or no one pointed out, they had the gt3 there too so may be the wheel set for that (if indeed they are slick).

Whichever way you look at it the tyres were very good indeed :-)

That is the one rear of the two in my picture. There are 2 slicks sitting on top of 1 Cup 2.



Having said that Sport Auto claimed they used a stickier set of Cup 2s (they offer 2 different Cup 2s apparently), which raises a lot of questions about tyre comparisons.

A GT3 wheel would have a centre-locking nut, would it not?

I think you would agree with me that, although it would not be impossible, it would be pretty unusual for a professional crew to have four mounted tyres sitting in a little group of their own, but with the tyres having come from different sets for different cars. Apart from the impracticality, there is too great a risk that someone would put a totally mismatched set on a car and that would cause a crash. If we can see treads on one of the tyres, I would suggest that the reason we cannot see treads on another tyre is not because it didn't have any.

I'm not trying to make a big deal out of this, but I do think it very unlikely that Merc or Sport Auto would set a time on true slicks but then pretend that they had been road tyres. If needs be I could find out, but I'd rather not bother someone by pursuing it.

Well when a front-engined RWD Merc weighing as much as a 918 with the bhp of a 458 beats a 918, naturally people scratch their heads and look for answers. And whilst it may not have been on slicks, the tyres it did use probably aren't that far off slicks wrt performance, because it's the only explanation.

And that we can all agree on, because there is nothing about this car that screams "faster than a 918 or 488", so that only leaves the tyres. Basic process of elimination. But no doubt Merc fan-boys will still cry foul when up against cars on Trofeos, even though they have the stickiest road legal tyres ever, apart from maybe Kumho V720 ACRs.
