Off the line, the 840i xDrive hits 100 km/h in 4.81 s versus 4.83 s for the M440i. The 0.02 s gap is negligible: both vehicles are neck and neck.
At 200 metres, the 840i xDrive is doing 142 km/h against 146 km/h for the M440i. The gap is 0.02 s. The gap remains stable from the start.
At 400 metres standing start, the M440i crosses the line in 12.93 s versus 13.05 s. The 0.12 s gap represents roughly 6 m of track - barely a car length.
Past 400 metres, the M440i continues to build its lead. At 600 metres, it runs at 205 km/h versus 198 km/h. At 1,000 metres, the M440i finishes in 23.15 s versus 23.65 s, with a 0.50 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 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 (4.53 kg/hp vs 5.39 kg/hp) and transmission (Automatic vs Automatic).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 7.33 seconds. The 0.02 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Over 0–100 km/h, M440i G22 and 840i xDrive G15 are neck and neck (4,81 s vs 4,83 s, no significant gap).
M440i G22 goes from 0 to 100 km/h in 4,83 seconds (calibrated simulation).
M440i G22: 374 hp, ratio 4,53 kg/hp. 840i xDrive G15: 333 hp, ratio 5,39 kg/hp.
M440i G22: 250 km/h. 840i xDrive G15: 250 km/h.
