Off the line, the M440i hits 100 km/h in 4.83 s versus 5.12 s for the 840i. At this point, the M440i leads by 0.29 s and sits roughly 2 m ahead.
At 200 metres, the M440i is doing 146 km/h against 140 km/h for the 840i. The gap is 0.21 s. The gap remains stable from the start.
At 400 metres standing start, the M440i crosses the line in 12.93 s versus 13.33 s. The 0.41 s gap represents roughly 20 m of track - two to three car lengths.
Past 400 metres, the M440i continues to build its lead. At 600 metres, it runs at 205 km/h versus 196 km/h. At 1,000 metres, the M440i finishes in 23.15 s versus 24.04 s, with a 0.89 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.
The M440i features all-wheel drive (AWD) against the 840i’s RWD. At low speeds (0-30, 0-50, 0-80 km/h), AWD doubles the driven contact area: all four wheels transmit torque to the road, virtually eliminating wheelspin at launch. This traction advantage is decisive in the range where the motor delivers peak torque, before power and aerodynamics take over.
Both rivals share the same electronic speed cap: the M440i and the 840i 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 5.20 kg/hp) and transmission (Automatic vs Automatic).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 7.71 seconds. The 0.29 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 5,12 s).
M440i G22 goes from 0 to 100 km/h in 4,83 seconds (calibrated simulation).
