Porsche 911 GT3 RS 991

The Porsche 911 GT3 RS 991 reaches 60 mph in 3.07 s (100 km/h in 3.22 s) and covers a standing quarter mile in 11.17 s, tripping the lights at 125.9 mph. It clears the first 60 ft in 1.78 s and the eighth mile in 7.23 s, reaching 100 mph in 7.11 s.

Simulated, not measured — computed from published kerb mass, rated power, gearing and drivetrain, then fitted to this car’s own published acceleration figures. Dry asphalt, 20 °C, sea level, 1 ft rollout.

About the 911 GT3 RS 991

The 2015 Porsche 911 GT3 RS 991 is a rear-drive naturally aspirated car of 1,420 kg with 493 bhp, which works out at 348 bhp per tonne. Rear drive and 348 bhp per tonne make the launch the hard part of the run: 60 ft takes 1.78 s. Against the 14,946 cars in the set it is the 322nd quickest to 60 mph, inside the fastest five per cent, and the 47th quickest of the 334 Porsches here. Its 125.9 mph trap speed sits about where its 0-60 puts it, so it launches and pulls in roughly equal measure. The simulation is trimmed to 9 of 11 published acceleration figures for this car.

Questions

What is the Porsche 911 GT3 RS 991 0-60 time?
The Porsche 911 GT3 RS 991 reaches 60 mph in 3.07 s, simulated on dry asphalt at 20 °C with a 1 ft rollout. That makes it the 322nd quickest of the 14,946 cars in the set.
What is the Porsche 911 GT3 RS 991 quarter mile time?
11.17 s at 125.9 mph. It reaches the eighth mile in 7.23 s and clears the first 60 ft in 1.78 s. These are theoretical times from a physics simulation, not measured runs.
How much power does the Porsche 911 GT3 RS 991 have?
493 bhp and 1,420 kg, which is 348 bhp per tonne. It is rear-drive, naturally aspirated, with 7 gears and a quoted top speed of 311 km/h. These are theoretical times from a physics simulation, not measured runs.
What cars are comparable to the Porsche 911 GT3 RS 991?
Closest here on pace: Porsche 911 GT3 991 facelift (3.05 s), Jaguar XE SV Project 8 (3.09 s), Ferrari Portofino 3.9 V8 600 (3.10 s). Each one can be raced against the Porsche 911 GT3 RS 991 in the panel at the top of this page. These are theoretical times from a physics simulation, not measured runs.
Are these real measured times?
No. Every figure on this page is produced by a physics simulation, not by a stopwatch at a drag strip. The Porsche 911 GT3 RS 991 is modelled from its published kerb mass, rated power, drivetrain and gearing, then trimmed until it reproduces 9 of its 11 published acceleration figures. Conditions are the same for every car in the set: dry asphalt, 20 °C, sea level, 1 ft rollout.
