Off the line, the XM 50e hits 100 km/h in 5.19 s versus 6.74 s for the X2 xDrive25e. At this point, the XM 50e leads by 1.55 s and sits roughly 8 m ahead.
At 200 metres, the XM 50e is doing 139 km/h against 122 km/h for the X2 xDrive25e. The gap is 0.82 s. The challenger starts to claw back ground.
At 400 metres standing start, the XM 50e crosses the line in 13.44 s versus 14.89 s. The 1.45 s gap represents roughly 59 m of track - a gap visible to the naked eye.
Past 400 metres, the XM 50e continues to build its lead. At 600 metres, it runs at 193 km/h versus 169 km/h. At 1,000 metres, the XM 50e finishes in 24.30 s versus 27.32 s, with a 3.02 s lead.
Both rivals are electronically governed, but not at the same level: the XM 50e is capped at 250 (i.e. 155 mph - industry threshold) km/h, the X2 xDrive25e at 195 km/h. This isn’t a physical engine limit - it’s a manufacturer choice, usually for tyre safety or homologation reasons. Neither car reaches its true aerodynamic top speed.
With two plug-in hybrid powertrains, the difference comes down to power-to-weight ratio (5.50 kg/hp vs 7.86 kg/hp) and transmission (Automatic vs Automatic).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 10.91 seconds. The 1.55 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 6,74 s).
XM 50e G09 goes from 0 to 100 km/h in 5,19 seconds (calibrated simulation).
