Off the line, the X4 M40d hits 100 km/h in 4.81 s versus 5.65 s for the X5 xDrive40i. At this point, the X4 M40d leads by 0.84 s and sits roughly 8 m ahead.
At 200 metres, the X4 M40d is doing 138 km/h against 131 km/h for the X5 xDrive40i. The gap is 0.53 s. The challenger starts to claw back ground.
At 400 metres standing start, the X4 M40d crosses the line in 13.14 s versus 13.93 s. The 0.78 s gap represents roughly 35 m of track - a gap visible to the naked eye.
Past 400 metres, the X4 M40d continues to build its lead. At 600 metres, it runs at 192 km/h versus 181 km/h. At 1,000 metres, the X4 M40d finishes in 24.09 s versus 25.54 s, with a 1.45 s lead. Both vehicles have similar top speeds (250 (i.e. 155 mph - industry threshold) vs 243 km/h), preventing any comeback.
Both rivals are electronically governed, but not at the same level: the X4 M40d is capped at 250 (i.e. 155 mph - industry threshold) km/h, the X5 xDrive40i at 243 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 6.31 kg/hp) and transmission (Automatic vs Automatic).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 8.87 seconds. The 0.84 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Over 0–100 km/h, X4 M40d G02 wins (4,81 s vs 5,65 s).
X4 M40d G02 goes from 0 to 100 km/h in 4,81 seconds (calibrated simulation).
