Off the line, the Bmw M4 Competition hits 100 km/h in 3.83 s versus 3.83 s for the Bmw M850i xDrive. The 0.00 s gap is negligible: both vehicles are neck and neck.
At 200 metres, the Bmw M4 Competition is doing 163 km/h against 160 km/h for the Bmw M850i xDrive. The gap is 0.03 s. The gap remains stable from the start.
At 400 metres standing start, the Bmw M4 Competition crosses the line in 11.61 s versus 11.71 s. The 0.10 s gap represents roughly 5 m of track - barely a car length.
Past 400 metres, the Bmw M4 Competition continues to build its lead. At 600 metres, it runs at 227 km/h versus 224 km/h. At 1,000 metres, the Bmw M4 Competition finishes in 20.89 s versus 21.07 s, with a 0.19 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 M850i xDrive and the Bmw M4 Competition 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 3.38 kg/hp) and transmission (Automatic vs Automatic).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 5.50 seconds. The 0.00 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Over 0–100 km/h, M850i xDrive G15 and M4 Competition F82 are neck and neck (3,83 s vs 3,83 s, no significant gap).
M850i xDrive G15 goes from 0 to 100 km/h in 3,83 seconds (calibrated simulation).
M850i xDrive G15: 530 hp, ratio 3,64 kg/hp. M4 Competition F82: 510 hp, ratio 3,38 kg/hp.
M850i xDrive G15: 250 km/h. M4 Competition F82: 250 km/h.
