Off the line, the Bmw M850i xDrive hits 100 km/h in 3.83 s versus 4.27 s for the Bmw M4 Coupe. At this point, the Bmw M850i xDrive leads by 0.43 s and sits roughly 4 m ahead.
At 200 metres, the Bmw M850i xDrive is doing 160 km/h against 151 km/h for the Bmw M4 Coupe. The gap is 0.37 s. The gap remains stable from the start.
At 400 metres standing start, the Bmw M850i xDrive crosses the line in 11.71 s versus 12.30 s. The 0.60 s gap represents roughly 31 m of track - a gap visible to the naked eye.
Past 400 metres, the Bmw M850i xDrive continues to build its lead. At 600 metres, it runs at 224 km/h versus 213 km/h. At 1,000 metres, the Bmw M850i xDrive finishes in 21.07 s versus 22.16 s, with a 1.08 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 Coupe 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 3.54 kg/hp) and transmission (Automatic vs Manual).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 6.23 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, M850i xDrive G15 wins (3,83 s vs 4,26 s).
M850i xDrive G15 goes from 0 to 100 km/h in 3,83 seconds (calibrated simulation).
