BMW M3 G80 vs BMW i8

Over a standing quarter mile on dry asphalt the BMW M3 G80 is the quicker car, covering it in 12.20 s at 117.7 mph against the BMW i8’s 12.53 s — a margin of 0.32 s. To 60 mph the BMW M3 G80 takes 3.96 s and the BMW i8 4.27 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.

Questions

Is the BMW M3 G80 or the BMW i8 faster?
The BMW M3 G80. Over a standing quarter mile it runs 12.20 s to the BMW i8's 12.53 s, a margin of 0.32 s, and it reaches 60 mph in 3.96 s against 4.27 s. These are theoretical times from a physics simulation, not measured runs.
What is the BMW M3 G80 0-60 time?
The BMW M3 G80 reaches 60 mph in 3.96 s, simulated on dry asphalt at 20 °C with a 1 ft rollout. It covers the standing quarter mile in 12.20 s at 117.7 mph.
What is the BMW i8 0-60 time?
The BMW i8 reaches 60 mph in 4.27 s, simulated on dry asphalt at 20 °C with a 1 ft rollout. It covers the standing quarter mile in 12.53 s at 111.7 mph.
What trap speed does each car run?
The BMW M3 G80 trips the lights at 117.7 mph and the BMW i8 at 111.7 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 M3 G80 and 10 of 10 for the BMW i8. Conditions are identical for both cars: dry asphalt, 20 °C, sea level, 1 ft rollout.
