Off the line, the Bmw X4 M40i hits 100 km/h in 4.87 s versus 5.73 s for the Cayenne S. At this point, the Bmw X4 M40i leads by 0.87 s and sits roughly 6 m ahead.
At 200 metres, the Bmw X4 M40i is doing 142 km/h against 133 km/h for the Cayenne S. 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 13.08 s versus 13.92 s. The 0.84 s gap represents roughly 38 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 186 km/h. At 1,000 metres, the Bmw X4 M40i finishes in 23.70 s versus 25.21 s, with a 1.51 s lead. Both vehicles have similar top speeds (255 vs 250 (i.e. 155 mph — industry threshold) km/h), preventing any comeback.
Both rivals are electronically governed, but not at the same level: the Cayenne S is capped at 258 km/h, the Bmw X4 M40i at 250 (i.e. 155 mph — industry threshold) 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 (4.92 kg/hp vs 5.18 kg/hp) and transmission (Unknown vs Automatic).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 8.75 seconds. The 0.87 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.
