Off the line, the X7 M50d hits 100 km/h in 5.49 s versus 9.49 s for the X2 sDrive18i. At this point, the X7 M50d leads by 4.00 s and sits roughly 24 m ahead.
At 200 metres, the X7 M50d is doing 132 km/h against 108 km/h for the X2 sDrive18i. The gap is 1.95 s. The challenger starts to claw back ground.
At 400 metres standing start, the X7 M50d crosses the line in 13.82 s versus 16.88 s. The 3.06 s gap represents roughly 108 m of track - a gap visible to the naked eye.
Past 400 metres, the X7 M50d continues to build its lead. At 600 metres, it runs at 184 km/h versus 149 km/h. At 1,000 metres, the X7 M50d finishes in 25.28 s versus 31.04 s, with a 5.77 s lead.
Both rivals are electronically governed, but not at the same level: the X7 M50d is capped at 250 (i.e. 155 mph - industry threshold) km/h, the X2 sDrive18i at 205 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 combustion powertrains, the difference comes down to power-to-weight ratio (6.15 kg/hp vs 10.37 kg/hp) and transmission (Automatic vs Automatic).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 16.03 seconds. The 4.00 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Over 0–100 km/h, X7 M50d G07 wins (5,49 s vs 9,49 s).
X7 M50d G07 goes from 0 to 100 km/h in 5,49 seconds (calibrated simulation).
