Is the Mercedes-AMG A45 (W176) 2.0 4MATIC 381 or the BMW M140i faster?
The Mercedes-AMG A45 (W176) 2.0 4MATIC 381. Over a standing quarter mile it runs 12.24 s to the BMW M140i's 12.38 s, a margin of 0.14 s, and it reaches 60 mph in 3.73 s against 3.90 s. These are theoretical times from a physics simulation, not measured runs.
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 BMW M140i 0-60 time?
The BMW M140i reaches 60 mph in 3.90 s, simulated on dry asphalt at 20 °C with a 1 ft rollout. It covers the standing quarter mile in 12.38 s at 111.0 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 BMW M140i at 111.0 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 9 of 10 for the BMW M140i. Conditions are identical for both cars: dry asphalt, 20 °C, sea level, 1 ft rollout.
