Porsche Cayenne (8-speed Tiptronic S) 958.1 vs BMW 225xe Active Tourer F44: which is truly faster?

Off the line, the 225xe Active Tourer hits 100 km/h in 6.83 s versus 7.55 s for the Cayenne (8-speed Tiptronic S). The instant torque of 385 Nm from the electric motor makes the difference. At this point, the 225xe Active Tourer leads by 0.72 s and sits roughly 6 m ahead.

At 200 metres, the 225xe Active Tourer is doing 124 km/h against 119 km/h for the Cayenne (8-speed Tiptronic S). The gap is 0.34 s. The challenger starts to claw back ground.

At 400 metres standing start, the 225xe Active Tourer crosses the line in 14.97 s versus 15.50 s. The 0.53 s gap represents roughly 22 m of track - two to three car lengths.

Past 400 metres, the 225xe Active Tourer continues to build its lead. At 600 metres, it runs at 172 km/h versus 166 km/h. At 1,000 metres, the 225xe Active Tourer finishes in 27.17 s versus 28.16 s, with a 1.00 s lead. Despite a higher top speed (224 km/h), the Cayenne (8-speed Tiptronic S) never recovers its launch deficit.

Both rivals are electronically governed, but not at the same level: the Cayenne (8-speed Tiptronic S) is capped at 230 km/h, the 225xe Active Tourer at 202 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.

Instant electric torque gives an advantage off the line. The higher top speed of the combustion engine gives an advantage over longer distances. The distance at which one catches the other depends on the top speed differential.

In European road use (130 km/h max), both vehicles reach the legal speed limit in under 11.88 seconds. The 0.72 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
