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

Off the line, the Cayenne S (8-speed Tiptronic S) hits 100 km/h in 5.81 s versus 6.83 s for the 225xe Active Tourer. Despite lacking instant torque, 420 hp of power compensates. At this point, the Cayenne S (8-speed Tiptronic S) leads by 1.02 s and sits roughly 12 m ahead.

At 200 metres, the Cayenne S (8-speed Tiptronic S) is doing 133 km/h against 124 km/h for the 225xe Active Tourer. The gap is 0.65 s. The challenger starts to claw back ground.

At 400 metres standing start, the Cayenne S (8-speed Tiptronic S) crosses the line in 13.99 s versus 14.97 s. The 0.98 s gap represents roughly 41 m of track - a gap visible to the naked eye.

Past 400 metres, the Cayenne S (8-speed Tiptronic S) continues to build its lead. At 600 metres, it runs at 185 km/h versus 172 km/h. At 1,000 metres, the Cayenne S (8-speed Tiptronic S) finishes in 25.35 s versus 27.17 s, with a 1.81 s lead.

Both rivals are electronically governed, but not at the same level: the Cayenne S (8-speed Tiptronic S) is capped at 258 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 10.70 seconds. The 1.02 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
