Porsche Cayenne S vs BMW 225xe Active Tourer F44: which is truly faster?

Off the line, the Cayenne S hits 100 km/h in 6.62 s versus 6.83 s for the 225xe Active Tourer. Despite lacking instant torque, 385 hp of power compensates. At this point, the Cayenne S leads by 0.21 s and sits roughly 4 m ahead.

At 200 metres, the Cayenne S is doing 125 km/h against 124 km/h for the 225xe Active Tourer. The gap is 0.15 s. The gap remains stable from the start.

At 400 metres standing start, the Cayenne S crosses the line in 14.74 s versus 14.97 s. The 0.24 s gap represents roughly 10 m of track - two to three car lengths.

Past 400 metres, the Cayenne S continues to build its lead. At 600 metres, it runs at 177 km/h versus 172 km/h. At 1,000 metres, the Cayenne S finishes in 26.61 s versus 27.17 s, with a 0.56 s lead.

Both rivals are electronically governed, but not at the same level: the Cayenne S is capped at 250 (i.e. 155 mph - industry threshold) 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 0.21 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
