Off the line, the M240i Convertible hits 100 km/h in 4.66 s versus 4.69 s for the M4 Convertible. The 0.03 s gap is negligible: both vehicles are neck and neck.
At 200 metres, the M4 Convertible is doing 151 km/h against 145 km/h for the M240i Convertible. The gap is 0.00 s. The gap remains stable from the start.
At 400 metres standing start, the M4 Convertible crosses the line in 12.64 s versus 12.85 s. The 0.21 s gap represents roughly 10 m of track - two to three car lengths.
Past 400 metres, the M4 Convertible continues to build its lead. At 600 metres, it runs at 213 km/h versus 201 km/h. At 1,000 metres, the M4 Convertible finishes in 22.51 s versus 23.31 s, with a 0.80 s lead. Both vehicles have similar top speeds (250 (i.e. 155 mph - industry threshold) vs 250 (i.e. 155 mph - industry threshold) km/h), preventing any comeback.
Both rivals share the same electronic speed cap: the M4 Convertible and the M240i Convertible are governed to 250 (i.e. 155 mph - industry threshold) km/h. At that speed, standard-fit tyres approach their safety threshold - an industrial ceiling common to most electric vehicles in this segment. Neither car shows its true aerodynamic potential in this duel.
With two combustion powertrains, the difference comes down to power-to-weight ratio (4.15 kg/hp vs 4.88 kg/hp) and transmission (Automatic vs Automatic).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 6.97 seconds. The 0.03 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Over 0–100 km/h, M4 Convertible F82 and M240i Convertible F44 are neck and neck (4,66 s vs 4,69 s, no significant gap).
M4 Convertible F82 goes from 0 to 100 km/h in 4,69 seconds (calibrated simulation).
M4 Convertible F82: 431 hp, ratio 4,15 kg/hp. M240i Convertible F44: 340 hp, ratio 4,88 kg/hp.
M4 Convertible F82: 250 km/h. M240i Convertible F44: 250 km/h.
