Off the line, the Bmw X7 M50i hits 100 km/h in 4.72 s versus 5.19 s for the Bmw XM 50e. Despite lacking instant torque, 530 hp of power compensates. At this point, the Bmw X7 M50i leads by 0.47 s and sits roughly 4 m ahead.
At 200 metres, the Bmw X7 M50i is doing 146 km/h against 139 km/h for the Bmw XM 50e. The gap is 0.33 s. The challenger starts to claw back ground.
At 400 metres standing start, the Bmw X7 M50i crosses the line in 12.87 s versus 13.44 s. The 0.57 s gap represents roughly 27 m of track — two to three car lengths.
Past 400 metres, the Bmw X7 M50i continues to build its lead. At 600 metres, it runs at 203 km/h versus 193 km/h. At 1,000 metres, the Bmw X7 M50i finishes in 23.20 s versus 24.30 s, with a 1.10 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 X7 M50i and the Bmw XM 50e 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 0.47 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Swap one of the two models to explore an equivalent duel in the same segment.
