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

Off the line, the Cayenne hits 100 km/h in 5.63 s versus 5.73 s for the Cayenne S. At this point, the Cayenne leads by 0.10 s and sits roughly 2 m ahead.

At 200 metres, the Cayenne is doing 133 km/h against 133 km/h for the Cayenne S. The gap is 0.09 s. The gap remains stable from the start.

At 400 metres standing start, the Cayenne crosses the line in 13.87 s versus 13.92 s. The 0.05 s gap represents roughly 2 m of track — barely a car length.

Past 400 metres, the situation changes. The Cayenne maxes out at 245 km/h while the Cayenne S keeps accelerating towards 255 km/h. At 600 metres, the gap has dropped to 0.00 s.

Around 588 metres, both vehicles are level. This is the inversion point: the Cayenne S overcomes its launch deficit thanks to a 10 km/h higher top speed.

At 1,000 metres, the Cayenne S finishes in 25.21 s versus 25.36 s. The 0.15 s delta shows an extremely tight race.

Both rivals are electronically governed, but not at the same level: the Cayenne S is capped at 258 km/h, the Cayenne at 245 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 5.84 kg/hp) and transmission (Unknown vs Unknown).

In European road use (130 km/h max), both vehicles reach the legal speed limit in under 8.75 seconds. The 0.10 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
