Off the line, the M850i xDrive Gran Coupe hits 100 km/h in 3.93 s versus 4.19 s for the M4. At this point, the M850i xDrive Gran Coupe leads by 0.26 s and sits roughly 4 m ahead.
At 200 metres, the M850i xDrive Gran Coupe is doing 159 km/h against 155 km/h for the M4. The gap is 0.26 s. The gap remains stable from the start.
At 400 metres standing start, the M850i xDrive Gran Coupe crosses the line in 11.88 s versus 12.23 s. The 0.35 s gap represents roughly 19 m of track - two to three car lengths.
Past 400 metres, the M850i xDrive Gran Coupe continues to build its lead. At 600 metres, it runs at 222 km/h versus 219 km/h. At 1,000 metres, the M850i xDrive Gran Coupe finishes in 21.34 s versus 21.86 s, with a 0.52 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 Gran Coupe and the 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 (3.79 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 6.20 seconds. The 0.26 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Over 0–100 km/h, M850i xDrive Gran Coupe G15 wins (3,93 s vs 4,19 s).
M850i xDrive Gran Coupe G15 goes from 0 to 100 km/h in 3,93 seconds (calibrated simulation).
