Off the line, the M4 Competition hits 100 km/h in 3.83 s versus 3.83 s for the M850i xDrive. The 0.00 s gap is negligible: both vehicles are neck and neck.
At 200 metres, the M4 Competition is doing 163 km/h against 160 km/h for the M850i xDrive. The gap is 0.03 s. The gap remains stable from the start.
At 400 metres standing start, the 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 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 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 M850i xDrive and the 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.
