Subaru WRX STI vs Mercedes-AMG A45 (W176) 2.0 4MATIC 381
Over a standing quarter mile on dry asphalt the Mercedes-AMG A45 (W176) 2.0 4MATIC 381 is the quicker car,
covering it in 12.24 s at
111.2 mph against the Subaru WRX STI’s
13.69 s — a margin of
1.45 s. To 60 mph the Mercedes-AMG A45 (W176) 2.0 4MATIC 381 takes
3.73 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.

Each car is trimmed to its own published figures —
9/10 for the Subaru WRX STI,
2/2 for the Mercedes-AMG A45 (W176) 2.0 4MATIC 381 —
so a heavier car can still be the quicker one if that is what it tests.
Is the Subaru WRX STI 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 Subaru WRX STI's 13.69 s, a margin of 1.45 s, and it reaches 60 mph in 3.73 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 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 Subaru WRX STI trips the lights at 101.6 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 Subaru WRX STI 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.
