Porsche Cayenne S 958.1 vs BMW X1 xDrive25i F48: which is truly faster?

Off the line, the Cayenne S hits 100 km/h in 5.73 s versus 6.66 s for the X1 xDrive25i. At this point, the Cayenne S leads by 0.93 s and sits roughly 7 m ahead.

At 200 metres, the Cayenne S is doing 133 km/h against 123 km/h for the X1 xDrive25i. The gap is 0.51 s. The challenger starts to claw back ground.

At 400 metres standing start, the Cayenne S crosses the line in 13.92 s versus 14.82 s. The 0.90 s gap represents roughly 38 m of track - a gap visible to the naked eye.

Past 400 metres, the Cayenne S continues to build its lead. At 600 metres, it runs at 186 km/h versus 171 km/h. At 1,000 metres, the Cayenne S finishes in 25.21 s versus 27.13 s, with a 1.93 s lead.

Both rivals are electronically governed, but not at the same level: the Cayenne S is capped at 258 km/h, the X1 xDrive25i at 235 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 6.86 kg/hp) and transmission (Unknown vs Automatic).

In European road use (130 km/h max), both vehicles reach the legal speed limit in under 10.63 seconds. The 0.93 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
