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

Off the line, the Panamera Turbo hits 100 km/h in 4.03 s versus 5.13 s for the Cayenne S. At this point, the Panamera Turbo leads by 1.10 s and sits roughly 8 m ahead.

At 200 metres, the Panamera Turbo is doing 156 km/h against 137 km/h for the Cayenne S. The gap is 0.87 s. The challenger starts to claw back ground.

At 400 metres standing start, the Panamera Turbo crosses the line in 12.02 s versus 13.45 s. The 1.43 s gap represents roughly 66 m of track — a gap visible to the naked eye.

Past 400 metres, the Panamera Turbo continues to build its lead. At 600 metres, it runs at 216 km/h versus 191 km/h. At 1,000 metres, the Panamera Turbo finishes in 21.74 s versus 24.50 s, with a 2.76 s lead.

Both rivals are electronically governed, but not at the same level: the Panamera Turbo is capped at 303 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 (3.58 kg/hp vs 4.96 kg/hp) and transmission (Automatic vs Unknown).

In European road use (130 km/h max), both vehicles reach the legal speed limit in under 8.11 seconds. The 1.10 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
