Porsche Cayenne V6 958.1 vs BMW X1 xDrive25i F48: which is truly faster?

Off the line, the X1 xDrive25i hits 100 km/h in 6.66 s versus 7.16 s for the Cayenne V6. At this point, the X1 xDrive25i leads by 0.50 s and sits roughly 3 m ahead.

At 200 metres, the X1 xDrive25i is doing 123 km/h against 122 km/h for the Cayenne V6. The gap is 0.18 s. The challenger starts to claw back ground.

At 400 metres standing start, the X1 xDrive25i crosses the line in 14.82 s versus 15.12 s. The 0.30 s gap represents roughly 13 m of track - two to three car lengths.

Past 400 metres, the X1 xDrive25i continues to build its lead. At 600 metres, it runs at 171 km/h versus 169 km/h. At 1,000 metres, the X1 xDrive25i finishes in 27.13 s versus 27.65 s, with a 0.52 s lead. Both vehicles have similar top speeds (223 vs 232 km/h), preventing any comeback.

Both rivals are electronically governed, but not at the same level: the Cayenne V6 is capped at 230 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 (6.56 kg/hp vs 6.86 kg/hp) and transmission (Manual vs Automatic).

In European road use (130 km/h max), both vehicles reach the legal speed limit in under 11.40 seconds. The 0.50 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
