Off the line, the Bmw M4 Coupe hits 100 km/h in 4.38 s versus 4.81 s for the Bmw 840i xDrive. The 0.43 s gap is negligible: both vehicles are neck and neck.
At 200 metres, the Bmw M4 Coupe is doing 157 km/h against 142 km/h for the Bmw 840i xDrive. The gap is 0.38 s. The gap remains stable from the start.
At 400 metres standing start, the Bmw M4 Coupe crosses the line in 12.21 s versus 13.05 s. The 0.84 s gap represents roughly 41 m of track - a gap visible to the naked eye.
Past 400 metres, the Bmw M4 Coupe continues to build its lead. At 600 metres, it runs at 221 km/h versus 198 km/h. At 1,000 metres, the Bmw M4 Coupe finishes in 21.75 s versus 23.65 s, with a 1.89 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 Bmw M4 Coupe and the Bmw 840i 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 (3.64 kg/hp vs 5.39 kg/hp) and transmission (Automatic vs Automatic).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 7.33 seconds. The 0.43 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Over 0–100 km/h, M4 Coupe F82 wins (4,38 s vs 4,81 s).
M4 Coupe F82 goes from 0 to 100 km/h in 4,38 seconds (calibrated simulation).
