Off the line, the X5 M50i hits 100 km/h in 4.34 s versus 4.64 s for the Cayenne S. At this point, the X5 M50i leads by 0.29 s and sits roughly 1 m ahead.
At 200 metres, the X5 M50i is doing 150 km/h against 145 km/h for the Cayenne S. The gap is 0.19 s. The challenger starts to claw back ground.
At 400 metres standing start, the X5 M50i crosses the line in 12.43 s versus 12.79 s. The 0.36 s gap represents roughly 18 m of track - two to three car lengths.
Past 400 metres, the X5 M50i continues to build its lead. At 600 metres, it runs at 209 km/h versus 202 km/h. At 1,000 metres, the X5 M50i finishes in 22.50 s versus 23.26 s, with a 0.76 s lead. Both vehicles have similar top speeds (250 (i.e. 155 mph - industry threshold) vs 264 km/h), preventing any comeback.
Both rivals are electronically governed, but not at the same level: the X5 M50i is capped at 250 (i.e. 155 mph - industry threshold) km/h, the Cayenne S at 264 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 (4.25 kg/hp vs 4.59 kg/hp) and transmission (Automatic vs Unknown).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 6.94 seconds. The 0.29 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
