Subaru WRX STI vs Porsche 911 Carrera 991

Over a standing quarter mile on dry asphalt the Porsche 911 Carrera 991 is the quicker car, covering it in 12.84 s at 111.2 mph against the Subaru WRX STI’s 13.69 s — a margin of 0.85 s. To 60 mph the Porsche 911 Carrera 991 takes 4.25 s and the Subaru WRX STI 5.27 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 Subaru WRX STI or the Porsche 911 Carrera 991 faster?
The Porsche 911 Carrera 991. Over a standing quarter mile it runs 12.84 s to the Subaru WRX STI's 13.69 s, a margin of 0.85 s, and it reaches 60 mph in 4.25 s against 5.27 s. These are theoretical times from a physics simulation, not measured runs.
What is the Subaru WRX STI 0-60 time?
The Subaru WRX STI reaches 60 mph in 5.27 s, simulated on dry asphalt at 20 °C with a 1 ft rollout. It covers the standing quarter mile in 13.69 s at 101.6 mph.
What is the Porsche 911 Carrera 991 0-60 time?
The Porsche 911 Carrera 991 reaches 60 mph in 4.25 s, simulated on dry asphalt at 20 °C with a 1 ft rollout. It covers the standing quarter mile in 12.84 s at 111.2 mph.
What trap speed does each car run?
The Subaru WRX STI trips the lights at 101.6 mph and the Porsche 911 Carrera 991 at 111.2 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 10 for the Subaru WRX STI and 10 of 10 for the Porsche 911 Carrera 991. Conditions are identical for both cars: dry asphalt, 20 °C, sea level, 1 ft rollout.
