Subaru WRX STI vs Infiniti Q50 2.2d 170

Over a standing quarter mile on dry asphalt the Subaru WRX STI is the quicker car, covering it in 13.69 s at 101.6 mph against the Infiniti Q50 2.2d 170’s 16.17 s — a margin of 2.48 s. To 60 mph the Subaru WRX STI takes 5.27 s and the Infiniti Q50 2.2d 170 8.07 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 Infiniti Q50 2.2d 170 faster?
The Subaru WRX STI. Over a standing quarter mile it runs 13.69 s to the Infiniti Q50 2.2d 170's 16.17 s, a margin of 2.48 s, and it reaches 60 mph in 5.27 s against 8.07 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 Infiniti Q50 2.2d 170 0-60 time?
The Infiniti Q50 2.2d 170 reaches 60 mph in 8.07 s, simulated on dry asphalt at 20 °C with a 1 ft rollout. It covers the standing quarter mile in 16.17 s at 87.0 mph.
What trap speed does each car run?
The Subaru WRX STI trips the lights at 101.6 mph and the Infiniti Q50 2.2d 170 at 87.0 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 2 of 2 for the Infiniti Q50 2.2d 170. Conditions are identical for both cars: dry asphalt, 20 °C, sea level, 1 ft rollout.
