Porsche 911 GT3 (992) vs Porsche 911 GT2 RS 991

Over a standing quarter mile on dry asphalt the Porsche 911 GT2 RS 991 is the quicker car, covering it in 10.14 s at 139.5 mph against the Porsche 911 GT3 (992)’s 11.01 s — a margin of 0.87 s. To 60 mph the Porsche 911 GT2 RS 991 takes 2.55 s and the Porsche 911 GT3 (992) 2.91 s.

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

Questions

Is the Porsche 911 GT3 (992) or the Porsche 911 GT2 RS 991 faster?
The Porsche 911 GT2 RS 991. Over a standing quarter mile it runs 10.14 s to the Porsche 911 GT3 (992)'s 11.01 s, a margin of 0.87 s, and it reaches 60 mph in 2.55 s against 2.91 s. These are theoretical times from a physics simulation, not measured runs.
What is the Porsche 911 GT3 (992) 0-60 time?
The Porsche 911 GT3 (992) reaches 60 mph in 2.91 s, simulated on dry asphalt at 20 °C with a 1 ft rollout. It covers the standing quarter mile in 11.01 s at 126.6 mph.
What is the Porsche 911 GT2 RS 991 0-60 time?
The Porsche 911 GT2 RS 991 reaches 60 mph in 2.55 s, simulated on dry asphalt at 20 °C with a 1 ft rollout. It covers the standing quarter mile in 10.14 s at 139.5 mph.
What trap speed does each car run?
The Porsche 911 GT3 (992) trips the lights at 126.6 mph and the Porsche 911 GT2 RS 991 at 139.5 mph at the end of the quarter mile. These are theoretical times from a physics simulation, not measured runs.
Are these real measured times?
No. Every time on this page is produced by a physics simulation, not by a stopwatch at a drag strip. Each car is modelled from its published kerb mass, rated power, drivetrain and gearing, then trimmed until it matches its own published acceleration figures — 9 of 11 for the Porsche 911 GT3 (992) and 10 of 11 for the Porsche 911 GT2 RS 991. Conditions are identical for both cars: dry asphalt, 20 °C, sea level, 1 ft rollout.
