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 is the Mercedes-AMG GLA45 2.0 4MATIC+ 387 0-60 time?
The Mercedes-AMG GLA45 2.0 4MATIC+ 387 reaches 60 mph in 3.91 s, simulated on dry asphalt at 20 °C with a 1 ft rollout. It covers the standing quarter mile in 12.49 s at 108.5 mph.
What trap speed does each car run?
The Mercedes-AMG A45 (W176) 2.0 4MATIC 381 trips the lights at 111.2 mph and the Mercedes-AMG GLA45 2.0 4MATIC+ 387 at 108.5 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 — 2 of 2 for the Mercedes-AMG A45 (W176) 2.0 4MATIC 381 and 2 of 2 for the Mercedes-AMG GLA45 2.0 4MATIC+ 387. Conditions are identical for both cars: dry asphalt, 20 °C, sea level, 1 ft rollout.
