Off the line, the Bmw X4 M40i hits 100 km/h in 4.75 s versus 5.58 s for the Bmw X5 xDrive40d. At this point, the Bmw X4 M40i leads by 0.84 s and sits roughly 6 m ahead.
At 200 metres, the Bmw X4 M40i is doing 142 km/h against 131 km/h for the Bmw X5 xDrive40d. The gap is 0.54 s. The challenger starts to claw back ground.
At 400 metres standing start, the Bmw X4 M40i crosses the line in 12.98 s versus 13.92 s. The 0.93 s gap represents roughly 41 m of track — a gap visible to the naked eye.
Past 400 metres, the Bmw X4 M40i continues to build its lead. At 600 metres, it runs at 198 km/h versus 181 km/h. At 1,000 metres, the Bmw X4 M40i finishes in 23.62 s versus 25.54 s, with a 1.92 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 Bmw X4 M40i is capped at 250 (i.e. 155 mph — industry threshold) km/h, the Bmw X5 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 (5.18 kg/hp vs 6.47 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.
Swap one of the two models to explore an equivalent duel in the same segment.
