Off the line, the Bmw M440i hits 100 km/h in 4.83 s versus 4.96 s for the Bmw 840d xDrive. Despite the faster sprint time, the Bmw 840d xDrive is 3 m further along the track at this moment: stronger low-speed acceleration offsets a slower run beyond 100 km/h.
At 200 metres, the Bmw M440i is doing 146 km/h against 139 km/h for the Bmw 840d xDrive. The gap is 0.08 s. The gap remains stable from the start.
At 400 metres standing start, the Bmw M440i crosses the line in 12.93 s versus 13.26 s. The 0.33 s gap represents roughly 16 m of track - two to three car lengths.
Past 400 metres, the Bmw M440i continues to build its lead. At 600 metres, it runs at 205 km/h versus 193 km/h. At 1,000 metres, the Bmw M440i finishes in 23.15 s versus 24.13 s, with a 0.99 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 and the Bmw 840d 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 5.72 kg/hp) and transmission (Automatic vs Automatic).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 7.70 seconds. The 0.13 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Over 0–100 km/h, M440i G22 wins (4,83 s vs 4,96 s).
M440i G22 goes from 0 to 100 km/h in 4,83 seconds (calibrated simulation).
