Porsche 911s have never been solely about straight-line performance. However, this doesn’t mean that they aren’t brutally fast when the throttle is pinned and there is an open stretch of road ahead.

To see just how quick the most powerful 911 of them all, the GT2 RS, really is, Motorsport Magazine jumped behind the wheel and launched one from a standstill to 300 km/h. After just 19.7 seconds, the sports car was traveling at 300 km/h.

During the high-speed sprint, the RS reach 100 km/h in roughly 3.2 seconds and 200 km/h in 8.4 seconds. To put these times into perspective, a McLaren 720S tested in similar conditions hit 100 km/h in 3.0 seconds, 200 km/h in 7.5 seconds, and 300 km/h in 18.1 seconds.

While the GT2 RS is slightly slower, the difference between the pair shouldn’t surprise anyone. Whereas the 720S has 710 hp, the GT2 RS makes do with 690 hp but more importantly, the 720S weighs just 1283 kg (2829 lbs) dry while the 911 tips the scales at 1470 kg (3241 lbs).

Around a track, it remains to be seen which will be quicker. Track tests of the McLaren 720S have shown it to be almost as fast as the McLaren P1 while the GT2 RS lapped the Nurburgring faster than both the McLaren P1 and Porsche 918 Spyder.

The sooner someone organizes a track test between the 720S, GT2 RS, and Huracan Performante, the better.
