Porsche Cayenne Turbo 958.2 vs Porsche Panamera 4S 970.1: which is truly faster?

Off the line, the Cayenne Turbo hits 100 km/h in 4.15 s versus 4.78 s for the Panamera 4S. At this point, the Cayenne Turbo leads by 0.63 s and sits roughly 5 m ahead.

At 200 metres, the Cayenne Turbo is doing 153 km/h against 142 km/h for the Panamera 4S. The gap is 0.46 s. The challenger starts to claw back ground.

At 400 metres standing start, the Cayenne Turbo crosses the line in 12.23 s versus 12.98 s. The 0.74 s gap represents roughly 36 m of track - a gap visible to the naked eye.

Past 400 metres, the Cayenne Turbo continues to build its lead. At 600 metres, it runs at 212 km/h versus 198 km/h. At 1,000 metres, the Cayenne Turbo finishes in 22.17 s versus 23.57 s, with a 1.41 s lead. Both vehicles have similar top speeds (278 vs 275 km/h), preventing any comeback.

Both rivals are electronically governed, but not at the same level: the Cayenne Turbo is capped at 278 km/h, the Panamera 4S at 283 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 (4.20 kg/hp vs 4.23 kg/hp) and transmission (Unknown vs Automatic).

In European road use (130 km/h max), both vehicles reach the legal speed limit in under 7.26 seconds. The 0.63 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
