Off the line, the M440i xDrive hits 100 km/h in 4.47 s versus 4.81 s for the 840i xDrive. At this point, the M440i xDrive leads by 0.34 s and sits roughly 4 m ahead.
At 200 metres, the M440i xDrive is doing 146 km/h against 142 km/h for the 840i xDrive. The gap is 0.25 s. The gap remains stable from the start.
At 400 metres standing start, the M440i xDrive crosses the line in 12.66 s versus 13.04 s. The 0.38 s gap represents roughly 18 m of track - two to three car lengths.
Past 400 metres, the M440i xDrive continues to build its lead. At 600 metres, it runs at 204 km/h versus 198 km/h. At 1,000 metres, the M440i xDrive finishes in 22.96 s versus 23.66 s, with a 0.69 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 M440i xDrive and the 840i xDrive 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 (4.65 kg/hp vs 5.21 kg/hp) and transmission (Automatic vs Automatic).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 7.34 seconds. The 0.34 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Over 0–100 km/h, M440i xDrive F32 wins (4,47 s vs 4,81 s).
M440i xDrive F32 goes from 0 to 100 km/h in 4,47 seconds (calibrated simulation).
