Off the line, the Bmw XM 50e hits 100 km/h in 5.19 s versus 5.25 s for the Bmw 540i. The instant torque of 700 Nm from the electric motor makes the difference. The 0.06 s gap is negligible: both vehicles are neck and neck.
At 200 metres, the Bmw XM 50e is doing 139 km/h against 139 km/h for the Bmw 540i. The gap is 0.04 s. The gap remains stable from the start.
At 400 metres standing start, the Bmw 540i crosses the line in 13.43 s versus 13.44 s. The 0.01 s gap represents roughly 0 m of track
Past 400 metres, the Bmw 540i continues to build its lead. At 600 metres, it runs at 196 km/h versus 193 km/h. At 1,000 metres, the Bmw 540i finishes in 24.11 s versus 24.30 s, with a 0.19 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 Bmw XM 50e features all-wheel drive (AWD) against the Bmw 540i’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 Bmw XM 50e and the Bmw 540i 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.
Instant electric torque gives an advantage off the line. The higher top speed of the combustion engine gives an advantage over longer distances. The distance at which one catches the other depends on the top speed differential.
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 7.89 seconds. The 0.06 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Over 0–100 km/h, XM 50e G09 and 540i G30 are neck and neck (5,19 s vs 5,25 s, no significant gap).
XM 50e G09 goes from 0 to 100 km/h in 5,19 seconds (calibrated simulation).
