Off the line, the Bmw M440i xDrive hits 100 km/h in 4.47 s versus 4.54 s for the Bmw M140i. The 0.07 s gap is negligible: both vehicles are neck and neck.
At 200 metres, the Bmw M440i xDrive is doing 146 km/h against 151 km/h for the Bmw M140i. The gap is 0.09 s. The gap remains stable from the start.
At 400 metres standing start, the Bmw M140i crosses the line in 12.60 s versus 12.66 s. The 0.06 s gap represents roughly 3 m of track - barely a car length.
Past 400 metres, the Bmw M140i continues to build its lead. At 600 metres, it runs at 210 km/h versus 204 km/h. At 1,000 metres, the Bmw M140i finishes in 22.65 s versus 22.96 s, with a 0.32 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 M440i xDrive and the Bmw M140i 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 4.32 kg/hp) and transmission (Automatic vs Automatic).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 6.77 seconds. The 0.07 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Over 0–100 km/h, M440i xDrive F32 and M140i F20LCI are neck and neck (4,47 s vs 4,54 s, no significant gap).
M440i xDrive F32 goes from 0 to 100 km/h in 4,47 seconds (calibrated simulation).
