The Subaru Impreza WRX (2009) reaches 60 mph in 4.94 s, simulated on dry asphalt at 20 °C with a 1 ft rollout. It covers the standing quarter mile in 13.61 s at 100.3 mph.
What trap speed does each car run?
The Subaru WRX STI trips the lights at 101.6 mph and the Subaru Impreza WRX (2009) at 100.3 mph at the end of the quarter mile.
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 9 of 10 for the Subaru Impreza WRX (2009). Conditions are identical for both cars: dry asphalt, 20 °C, sea level, 1 ft rollout.
