BMW M4 G82 vs Rolls-Royce Spectre

Over a standing quarter mile on dry asphalt the BMW M4 G82 is the quicker car, covering it in 12.08 s at 118.1 mph against the Rolls-Royce Spectre’s 12.28 s — a margin of 0.20 s. To 60 mph the BMW M4 G82 takes 3.82 s and the Rolls-Royce Spectre 3.93 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.

Questions

Is the BMW M4 G82 or the Rolls-Royce Spectre faster?
The BMW M4 G82. Over a standing quarter mile it runs 12.08 s to the Rolls-Royce Spectre's 12.28 s, a margin of 0.20 s, and it reaches 60 mph in 3.82 s against 3.93 s. These are theoretical times from a physics simulation, not measured runs.
What is the BMW M4 G82 0-60 time?
The BMW M4 G82 reaches 60 mph in 3.82 s, simulated on dry asphalt at 20 °C with a 1 ft rollout. It covers the standing quarter mile in 12.08 s at 118.1 mph.
What is the Rolls-Royce Spectre 0-60 time?
The Rolls-Royce Spectre reaches 60 mph in 3.93 s, simulated on dry asphalt at 20 °C with a 1 ft rollout. It covers the standing quarter mile in 12.28 s at 116.1 mph.
What trap speed does each car run?
The BMW M4 G82 trips the lights at 118.1 mph and the Rolls-Royce Spectre at 116.1 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 BMW M4 G82 and 5 of 5 for the Rolls-Royce Spectre. Conditions are identical for both cars: dry asphalt, 20 °C, sea level, 1 ft rollout.
