Porsche 911 GT2 RS lap time at Nürburgring GP Sprint

You're asking that on the wrong laptime page, I'll answer anyway

All the manufacturers and most magazines test on that short version of the track (Autobild being the most notably exception, using only the full track), however, Porsche does not claim the lenght of the lap, but, since factory claims have been met on the full track and or reached fairly easy on the 20.6km one, is more than likely than Porsche claims are for the full track (IMHO).

There was a claim that the GT2 RS actually ran a shorter version of the track (200+meters shorter) to get its time of 7:18. The track length is also not listed on wikipedia as it is for other cars. Has anyone heard of this?

Nope, reason? it was a very cold day, ~4°c if my memory doesn't fail me, the same goes for the Aventador laptime, in the case of the GT2 RS its Pilot Sport Cups are very sensitive to low temperatures.

slower than gt3 rs 4.0? Driven by Best Motoring?
