Off the line, the XM 50e hits 100 km/h in 5.19 s versus 5.32 s for the 740Le xDrive iPerformance. Despite the faster sprint time, the 740Le xDrive iPerformance is 5 m further along the track at this moment: stronger low-speed acceleration offsets a slower run beyond 100 km/h.
At 200 metres, the 740Le xDrive iPerformance is doing 134 km/h against 139 km/h for the XM 50e. The gap is 0.05 s. The gap remains stable from the start.
At 400 metres standing start, the XM 50e crosses the line in 13.44 s versus 13.54 s. The 0.10 s gap represents roughly 5 m of track - barely a car length.
Past 400 metres, the XM 50e continues to build its lead. At 600 metres, it runs at 193 km/h versus 188 km/h. At 1,000 metres, the XM 50e finishes in 24.30 s versus 24.72 s, with a 0.43 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 XM 50e and the 740Le xDrive iPerformance 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 plug-in hybrid powertrains, the difference comes down to power-to-weight ratio (5.50 kg/hp vs 6.13 kg/hp) and transmission (Automatic vs Automatic).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 8.34 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, XM 50e G09 wins (5,19 s vs 5,32 s).
XM 50e G09 goes from 0 to 100 km/h in 5,19 seconds (calibrated simulation).
