Porsche Cayenne GTS 958.2 vs Porsche Cayenne S 958.2: which is truly faster?

Off the line, the Cayenne GTS hits 100 km/h in 4.92 s versus 5.13 s for the Cayenne S. At this point, the Cayenne GTS leads by 0.21 s and sits roughly 2 m ahead.

At 200 metres, the Cayenne GTS is doing 141 km/h against 137 km/h for the Cayenne S. The gap is 0.20 s. The gap remains stable from the start.

At 400 metres standing start, the Cayenne GTS crosses the line in 13.11 s versus 13.45 s. The 0.34 s gap represents roughly 16 m of track — two to three car lengths.

Past 400 metres, the Cayenne GTS continues to build its lead. At 600 metres, it runs at 195 km/h versus 191 km/h. At 1,000 metres, the Cayenne GTS finishes in 23.91 s versus 24.50 s, with a 0.59 s lead. Both vehicles have similar top speeds (262 vs 251 (i.e. 155 mph — industry threshold) km/h), preventing any comeback.

Both rivals are electronically governed, but not at the same level: the Cayenne GTS is capped at 262 km/h, the Cayenne S at 257 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 (4.80 kg/hp vs 4.96 kg/hp) and transmission (auto vs auto).

In European road use (130 km/h max), both vehicles reach the legal speed limit in under 8.11 seconds. The 0.21 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
