Off the line, the Bmw X4 M40i hits 100 km/h in 4.75 s versus 5.13 s for the Cayenne S. At this point, the Bmw X4 M40i leads by 0.38 s and sits roughly 3 m ahead.
At 200 metres, the Bmw X4 M40i is doing 142 km/h against 137 km/h for the Cayenne S. The gap is 0.29 s. The gap remains stable from the start.
At 400 metres standing start, the Bmw X4 M40i crosses the line in 12.98 s versus 13.45 s. The 0.47 s gap represents roughly 22 m of track - two to three car lengths.
Past 400 metres, the Bmw X4 M40i continues to build its lead. At 600 metres, it runs at 198 km/h versus 191 km/h. At 1,000 metres, the Bmw X4 M40i finishes in 23.62 s versus 24.50 s, with a 0.88 s lead. Both vehicles have similar top speeds (251 (i.e. 155 mph - industry threshold) 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 257 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 (4.96 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 8.11 seconds. The 0.38 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.
