Off the line, the Bmw M850i xDrive hits 100 km/h in 3.83 s versus 4.24 s for the Bmw M4. At this point, the Bmw M850i xDrive leads by 0.41 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. The gap is 0.41 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 12.38 s. The 0.67 s gap represents roughly 35 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 212 km/h. At 1,000 metres, the Bmw M850i xDrive finishes in 21.07 s versus 22.29 s, with a 1.21 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 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 6.44 seconds. The 0.41 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Swap one of the two models to explore an equivalent duel in the same segment.
