Onboard: Porsche 911 GT2 RS Beats its Official Top Speed
Porsche says the 911 GT2 RS can sprint from 0-60 mph in 2.7 seconds and achieve a top-speed of 211 mph.
However, in the above YouTube video, posted by Johnny Bohmer Proving Grounds, the 911 GT2 RS has achieved maximum speed of 219 mph. For reference, JBPG has also uploaded a review of the McLaren Senna, in which the supercar has achieved a top-speed of 204 mph.Â
The GT2 RS features a 3.8-liter twin-turbocharged flat-six engine that produces 690 horsepower and 550 pound-feet of torque. This engine powers the 991 Turbo and the Turbo S models also. However, in the 991.2 Turbo S, this engine produces no more than 572 horsepower. Additionally, the GT2 RS carries a 7-speed PDK gearbox, which sends the engine’s power to the rear wheels. The supercar also features carbon-ceramic brakes, rear-wheel steering and Michelin Pilot Sport Cup 2 tires.  Â
In 2017, a factory-spec GT2 RS set a lap-record around the Nurburgring race-track, after it had went around the race-track in 6 minutes 47 seconds. However, the Lamborghini Aventador SVJ broke that record last year (6 minutes 44 seconds). Yet the GT2 RS was nearly 10 seconds quicker than the Porsche 918 Spyder hypercar, which competes with the Ferrari LaFerrari and the McLaren P1. Indeed, when it was launched, the GT2 had a starting price of around $295,000. Meanwhile, the 918 had a starting price of $845,000.
The 911 GT2 RS is a track car. And a track car produces high amounts of downforce, because the latter helps the vehicle to travel faster through the corners. For instance, the GT2 RS produces 750 pounds (340 kg) of downforce at 211 mph. Meanwhile, the McLaren Senna can produce over 1,763 pounds (800 kg) of downforce.
However, downforce has a direct correlation with drag. This means that if the downforce on a vehicle increases, the drag on that vehicle would also increase. And drag negatively affects the straight-line speed of a vehicle. Hence, the aforementioned performance figures of the GT2 RS are truly remarkable.
