Porsche Cayenne S 958.1 vs Porsche Cayenne Coupe E3.1: which is truly faster?

Off the line, the Cayenne S hits 100 km/h in 5.73 s versus 5.77 s for the Cayenne Coupe. The 0.04 s gap is negligible: both vehicles are neck and neck.

At 200 metres, the Cayenne Coupe is doing 131 km/h against 133 km/h for the Cayenne S. The gap is 0.03 s. The gap remains stable from the start.

At 400 metres standing start, the Cayenne S crosses the line in 13.92 s versus 13.99 s. The 0.07 s gap represents roughly 3 m of track — barely a car length.

Past 400 metres, the Cayenne S continues to build its lead. At 600 metres, it runs at 186 km/h versus 181 km/h. At 1,000 metres, the Cayenne S finishes in 25.21 s versus 25.67 s, with a 0.46 s lead. Both vehicles have similar top speeds (255 vs 243 km/h), preventing any comeback.

Both rivals are electronically governed, but not at the same level: the Cayenne S is capped at 258 km/h, the Cayenne Coupe at 243 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 6.22 kg/hp) and transmission (Unknown vs Unknown).

In European road use (130 km/h max), both vehicles reach the legal speed limit in under 9.01 seconds. The 0.04 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
