Questions

Is the Audi S3 Sportback or the Mercedes-AMG A45 (W176) 2.0 4MATIC 381 faster?
The Mercedes-AMG A45 (W176) 2.0 4MATIC 381. Over a standing quarter mile it runs 12.24 s to the Audi S3 Sportback's 13.79 s, a margin of 1.55 s, and it reaches 60 mph in 3.73 s against 5.25 s. These are theoretical times from a physics simulation, not measured runs.
What is the Audi S3 Sportback 0-60 time?
The Audi S3 Sportback reaches 60 mph in 5.25 s, simulated on dry asphalt at 20 °C with a 1 ft rollout. It covers the standing quarter mile in 13.79 s at 101.5 mph.
What is the Mercedes-AMG A45 (W176) 2.0 4MATIC 381 0-60 time?
The Mercedes-AMG A45 (W176) 2.0 4MATIC 381 reaches 60 mph in 3.73 s, simulated on dry asphalt at 20 °C with a 1 ft rollout. It covers the standing quarter mile in 12.24 s at 111.2 mph.
What trap speed does each car run?
The Audi S3 Sportback trips the lights at 101.5 mph and the Mercedes-AMG A45 (W176) 2.0 4MATIC 381 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 Audi S3 Sportback and 2 of 2 for the Mercedes-AMG A45 (W176) 2.0 4MATIC 381. Conditions are identical for both cars: dry asphalt, 20 °C, sea level, 1 ft rollout.
