Porsche Cayenne E-Hybrid Coupe E3.1 vs Porsche Cayenne GTS 958.2: which is truly faster?

Off the line, the Cayenne E-Hybrid Coupe hits 100 km/h in 4.84 s versus 4.92 s for the Cayenne GTS. The instant torque of 700 Nm from the electric motor makes the difference. The 0.08 s gap is negligible: both vehicles are neck and neck.

At 200 metres, the Cayenne E-Hybrid Coupe is doing 139 km/h against 141 km/h for the Cayenne GTS. The gap is 0.06 s. The gap remains stable from the start.

At 400 metres standing start, the Cayenne GTS crosses the line in 13.11 s versus 13.14 s. The 0.03 s gap represents roughly 1 m of track

Past 400 metres, the Cayenne GTS continues to build its lead. At 600 metres, it runs at 195 km/h versus 193 km/h. At 1,000 metres, the Cayenne GTS finishes in 23.91 s versus 24.06 s, with a 0.16 s lead. Both vehicles have similar top speeds (253 vs 262 km/h), preventing any comeback.

Both rivals are electronically governed, but not at the same level: the Cayenne E-Hybrid Coupe is capped at 253 km/h, the Cayenne GTS at 262 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 7.56 seconds. The 0.08 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
