The report says that "the Porsche has competed in the long-awaited road configuration" and, as a central insight, "the McLaren has the much more stable rear axel".
A few further interesting statements: "the McLaren draws its precision from a carbon fiber chassis, which allows further dramatic leaps in development in the periphery. By contrast, with the completely squeezed out 911 concept and the heavy engine in the rear, the Porsche should be pretty much at the end". At this point, reference is made to the Ferrari 488 and Lamborghini Huracan with the following note: "...both are still made of metal (like the Porsche)...".
Regarding other published GT2 RS-lap times the following statement: "the GT2 RS-chassis can be changed in character (camber/track). For record runs, as they are allowed to do by colleagues from the "Auto Motor and Sport"-magazine, the wheels may be "X-legged" and Michelin Pilot Sport Cup 2 ZB tires may be mounted, which looks suspiciously like slik's. The GT2 RS is no longer standard after this change."

Not mentioned here, but broad powerband matters. McLaren tunes their turbo engines for an 8400 rpm redline. Heck, they would on even put it on a scooter (if they had one). Broader torque band means more area under the curve, which means more acceleration through the gear.

I am also wondering what is the difference between Cup 2 "R" and "ZP"? I think the new "R" is even more extreme.
The GT2 RS was tested with the "R" tyre in Sport Auto and Autobild test.
ZP are run-flats (or "zero pressure").

Yes I know, but what compound is it, similar to the new "R" tyre? I see that these "ZP" tyres have a impressive grip when warmed up but little grip when cold, like the "R" tyre. Both are typical track tyres for sure.
I would tend to think the R versions have more ultimate grip over the ZP. ZP design is compromised as it has to account for reinforcements in order for the tire to still run once it is punctured.

Tried to make a summary of the test for my blog. German speakers, do not hesitate to correct if any issue as I am not fluent and also relied on Google for some parts :
Aesthetically, the difference between the two cars is very marked, the McLaren doing in sobriety while the Porsche, with all its aerodynamic features, does not hide that its primary destination is the track. This does not prevent the McLaren from benefiting from a very advanced aerodynamics, which glues it to the ground in curves and makes it easier to control than the Porsche.
Both are catapulted by their boiling engine at the exit of curves, the Porsche explosively and with a slight indiscipline; the McLaren always sober.
In general, the behavior of the McLaren is typical of a car with a carbon chassis. Accurate, neutral, it faithfully transmits all information to the driver. This chassis can tame the 720 hp and 770 Nm transmitted to the only rear wheels stress-free and with disconcerting ease. It's a masterpiece of engineering!
Tested in road configuration (suspension settings and and rear wing orientation as tactory defined, standard Michelin Sport Cup 2 tires), the GT2 RS has struggled behind the McLaren, showing much greater nervousness and demanding much more of its pilot. This translates into a lap time (on the GP circuit of Hockenheim) 0.9 seconds slower.
On open road, the McLaren continues to be more considerate than the Porsche, its wheels following the irregularities of the road while those of the Porsche jump over. If the turbo lag of the McLaren 720S is more pronounced than in the Porsche GT2 RS, the gearbox retrograde less often, taking advantage of the engine torque available over a wide range of speeds. The McLaren is here also faster and still requires little effort ... which makes it also less spectacular!
The McLaren impresses, not only with its performance, but also with the ease with which it delivers its dynamic potential. These are two opposing visions, but in the end, the McLaren dominates the Porsche in all measurable areas and it even allows itself to be cheaper. It is therefore a clear victory and without discussion.

That seems to be referring to the tramlining effect often experienced with wider tyres.
I disagree. Runing on my 675lt the trofeos, not 2018 generation and the p zero corsa on my 720s, the trofeo 2017 is still stickier and significant gripier than the 2018 p corsa on the 720s.
Whilst the trofeo r performe longuer on a track (more laps on a constant temp frame) the p corsa his significant adventage on normal road, cold roads and of course rain. But it cant mach the trofeo R once grip and temp is available.
you can argue now, that the lt runs the trofeo and the 720 the p corsa and the car itself make a big diff, but at
the end you feel the diff of the tyres very well

Meaning none of these two were able to beat their claimed figures?
