Off the line, the X7 M50i hits 100 km/h in 4.74 s versus 6.12 s for the X7 xDrive40d. At this point, the X7 M50i leads by 1.38 s and sits roughly 7 m ahead.
At 200 metres, the X7 M50i is doing 144 km/h against 126 km/h for the X7 xDrive40d. The gap is 0.81 s. The challenger starts to claw back ground.
At 400 metres standing start, the X7 M50i crosses the line in 12.92 s versus 14.39 s. The 1.47 s gap represents roughly 62 m of track - a gap visible to the naked eye.
Past 400 metres, the X7 M50i continues to build its lead. At 600 metres, it runs at 201 km/h versus 174 km/h. At 1,000 metres, the X7 M50i finishes in 23.38 s versus 26.45 s, with a 3.07 s lead. Both vehicles have similar top speeds (250 (i.e. 155 mph - industry threshold) vs 245 km/h), preventing any comeback.
Both rivals are electronically governed, but not at the same level: the X7 M50i is capped at 250 (i.e. 155 mph - industry threshold) km/h, the X7 xDrive40d at 245 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 (4.70 kg/hp vs 7.26 kg/hp) and transmission (Automatic vs Automatic).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 9.90 seconds. The 1.38 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Over 0–100 km/h, X7 M50i G07 wins (4,74 s vs 6,12 s).
X7 M50i G07 goes from 0 to 100 km/h in 4,74 seconds (calibrated simulation).
