Off the line, the 545e xDrive hits 100 km/h in 4.68 s versus 5.19 s for the XM 50e. At this point, the 545e xDrive leads by 0.52 s and sits roughly 7 m ahead.
At 200 metres, the 545e xDrive is doing 143 km/h against 139 km/h for the XM 50e. The gap is 0.39 s. The challenger starts to claw back ground.
At 400 metres standing start, the 545e xDrive crosses the line in 12.91 s versus 13.44 s. The 0.52 s gap represents roughly 25 m of track - two to three car lengths.
Past 400 metres, the 545e xDrive continues to build its lead. At 600 metres, it runs at 200 km/h versus 193 km/h. At 1,000 metres, the 545e xDrive finishes in 23.40 s versus 24.30 s, with a 0.90 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 545e 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 plug-in hybrid powertrains, the difference comes down to power-to-weight ratio (5.50 kg/hp vs 4.94 kg/hp) and transmission (Automatic vs Automatic).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 7.89 seconds. The 0.52 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Over 0–100 km/h, 545e xDrive G30 wins (4,67 s vs 5,19 s).
XM 50e G09 goes from 0 to 100 km/h in 5,19 seconds (calibrated simulation).
XM 50e G09: 476 hp, ratio 5,50 kg/hp. 545e xDrive G30: 394 hp, ratio 4,94 kg/hp.
XM 50e G09: 250 km/h. 545e xDrive G30: 250 km/h.
