Porsche Panamera Turbo 970.1 vs Porsche 911 Turbo 991.1: which is truly faster?

Off the line, the 911 Turbo hits 100 km/h in 3.22 s versus 4.03 s for the Panamera Turbo. At this point, the 911 Turbo leads by 0.81 s and sits roughly 8 m ahead.

At 200 metres, the 911 Turbo is doing 170 km/h against 156 km/h for the Panamera Turbo. The gap is 0.71 s. The gap remains stable from the start.

At 400 metres standing start, the 911 Turbo crosses the line in 10.97 s versus 12.02 s. The 1.05 s gap represents roughly 55 m of track - a gap visible to the naked eye.

Past 400 metres, the 911 Turbo continues to build its lead. At 600 metres, it runs at 235 km/h versus 216 km/h. At 1,000 metres, the 911 Turbo finishes in 19.89 s versus 21.74 s, with a 1.85 s lead.

Both rivals are electronically governed, but not at the same level: the Panamera Turbo is capped at 303 km/h, the 911 Turbo at 314 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 3.07 kg/hp) and transmission (Automatic vs Automatic).

In European road use (130 km/h max), both vehicles reach the legal speed limit in under 5.85 seconds. The 0.81 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
