Off the line, the Bmw X4 M40d hits 100 km/h in 4.94 s versus 5.78 s for the Bmw X3 xDrive30d. At this point, the Bmw X4 M40d leads by 0.84 s and sits roughly 7 m ahead.
At 200 metres, the Bmw X4 M40d is doing 137 km/h against 129 km/h for the Bmw X3 xDrive30d. The gap is 0.52 s. The challenger starts to claw back ground.
At 400 metres standing start, the Bmw X4 M40d crosses the line in 13.29 s versus 14.11 s. The 0.83 s gap represents roughly 36 m of track - a gap visible to the naked eye.
Past 400 metres, the Bmw X4 M40d continues to build its lead. At 600 metres, it runs at 190 km/h versus 178 km/h. At 1,000 metres, the Bmw X4 M40d finishes in 24.38 s versus 25.96 s, with a 1.58 s lead. Both vehicles have similar top speeds (250 (i.e. 155 mph - industry threshold) vs 240 km/h), preventing any comeback.
Both rivals are electronically governed, but not at the same level: the Bmw X4 M40d is capped at 250 (i.e. 155 mph - industry threshold) km/h, the Bmw X3 xDrive30d at 240 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 (5.81 kg/hp vs 6.87 kg/hp) and transmission (Automatic vs Automatic).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 9.29 seconds. The 0.84 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Swap one of the two models to explore an equivalent duel in the same segment.
