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 Audi S3 Sportback and 10 of 10 for the Audi S4 B8 (2009). Conditions are identical for both cars: dry asphalt, 20 °C, sea level, 1 ft rollout.
