About the 911 GT3 991 facelift

The 2017 Porsche 911 GT3 991 facelift is a rear-drive naturally aspirated car of 1,413 kg with 493 bhp, which works out at 349 bhp per tonne. Rear drive and 349 bhp per tonne make the launch the hard part of the run: 60 ft takes 1.77 s. Against the 14,946 cars in the set it is the 302nd quickest to 60 mph, inside the fastest five per cent, and the 44th quickest of the 334 Porsches here. Its 126.5 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 991 facelift 0-60 time?
The Porsche 911 GT3 991 facelift reaches 60 mph in 3.05 s, simulated on dry asphalt at 20 °C with a 1 ft rollout. That makes it the 302nd quickest of the 14,946 cars in the set.
What is the Porsche 911 GT3 991 facelift quarter mile time?
11.12 s at 126.5 mph. It reaches the eighth mile in 7.19 s and clears the first 60 ft in 1.77 s. These are theoretical times from a physics simulation, not measured runs.
How much power does the Porsche 911 GT3 991 facelift have?
493 bhp and 1,413 kg, which is 349 bhp per tonne. It is rear-drive, naturally aspirated, with 7 gears and a quoted top speed of 320 km/h. These are theoretical times from a physics simulation, not measured runs.
What cars are comparable to the Porsche 911 GT3 991 facelift?
Closest here on pace: Porsche 911 GT3 992 facelift (3.06 s), Ruf Turbo RT 600 (3.01 s), Ferrari GTC4Lusso T (3.05 s). Each one can be raced against the Porsche 911 GT3 991 facelift 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 991 facelift 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.

Figures regenerated 2026-10-12. Every number on this page is computed by the simulator at build time, so the page and the app can never disagree.
