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

Off the line, the Panamera Turbo hits 100 km/h in 3.92 s versus 4.15 s for the Cayenne Turbo. At this point, the Panamera Turbo leads by 0.23 s and sits roughly 5 m ahead.

At 200 metres, the Panamera Turbo is doing 153 km/h against 153 km/h for the Cayenne Turbo. The gap is 0.21 s. The gap remains stable from the start.

At 400 metres standing start, the Panamera Turbo crosses the line in 12.01 s versus 12.23 s. The 0.22 s gap represents roughly 12 m of track - two to three car lengths.

Past 400 metres, the Panamera Turbo continues to build its lead. At 600 metres, it runs at 213 km/h versus 212 km/h. At 1,000 metres, the Panamera Turbo finishes in 21.90 s versus 22.17 s, with a 0.27 s lead.

Both rivals are electronically governed, but not at the same level: the Panamera Turbo is capped at 303 km/h, the Cayenne Turbo at 278 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 4.20 kg/hp) and transmission (Automatic vs Unknown).

In European road use (130 km/h max), both vehicles reach the legal speed limit in under 6.17 seconds. The 0.23 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
