Off the line, the M850i xDrive hits 100 km/h in 3.76 s versus 4.83 s for the M440i. At this point, the M850i xDrive leads by 1.07 s and sits roughly 10 m ahead.
At 200 metres, the M850i xDrive is doing 162 km/h against 146 km/h for the M440i. The gap is 0.87 s. The challenger starts to claw back ground.
At 400 metres standing start, the M850i xDrive crosses the line in 11.65 s versus 12.93 s. The 1.28 s gap represents roughly 63 m of track - a gap visible to the naked eye.
Past 400 metres, the M850i xDrive continues to build its lead. At 600 metres, it runs at 226 km/h versus 205 km/h. At 1,000 metres, the M850i xDrive finishes in 20.97 s versus 23.15 s, with a 2.18 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 M440i 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 (3.57 kg/hp vs 4.53 kg/hp) and transmission (Automatic vs Automatic).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 7.06 seconds. The 1.07 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 (3,76 s vs 4,83 s).
M850i xDrive G15 goes from 0 to 100 km/h in 3,76 seconds (calibrated simulation).
