Off the line, the M440d xDrive hits 100 km/h in 4.57 s versus 4.69 s for the M4 Convertible. At this point, the M440d xDrive leads by 0.12 s and sits roughly 9 m ahead.
At 200 metres, the M440d xDrive is doing 140 km/h against 151 km/h for the M4 Convertible. The gap is 0.10 s. The gap remains stable from the start.
At 400 metres standing start, the M4 Convertible crosses the line in 12.64 s versus 12.89 s. The 0.25 s gap represents roughly 12 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 196 km/h. At 1,000 metres, the M4 Convertible finishes in 22.51 s versus 23.61 s, with a 1.10 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 M440d xDrive 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 5.38 kg/hp) and transmission (Automatic vs Automatic).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 7.21 seconds. The 0.12 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Over 0–100 km/h, M440d xDrive G22 wins (4,57 s vs 4,69 s).
M4 Convertible F82 goes from 0 to 100 km/h in 4,69 seconds (calibrated simulation).
