Off the line, the X3 M40d hits 100 km/h in 4.99 s versus 6.17 s for the X7 xDrive40i. At this point, the X3 M40d leads by 1.18 s and sits roughly 10 m ahead.
At 200 metres, the X3 M40d is doing 137 km/h against 127 km/h for the X7 xDrive40i. The gap is 0.70 s. The challenger starts to claw back ground.
At 400 metres standing start, the X3 M40d crosses the line in 13.34 s versus 14.39 s. The 1.05 s gap represents roughly 45 m of track - a gap visible to the naked eye.
Past 400 metres, the X3 M40d continues to build its lead. At 600 metres, it runs at 189 km/h versus 176 km/h. At 1,000 metres, the X3 M40d finishes in 24.47 s versus 26.32 s, with a 1.86 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 X3 M40d is capped at 250 (i.e. 155 mph - industry threshold) km/h, the X7 xDrive40i 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 (5.94 kg/hp vs 6.82 kg/hp) and transmission (Automatic vs Automatic).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 9.77 seconds. The 1.18 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Over 0–100 km/h, X3 M40d G01 wins (4,99 s vs 6,17 s).
X3 M40d G01 goes from 0 to 100 km/h in 4,99 seconds (calibrated simulation).
