Porsche Cayenne Turbo 958.1 vs Porsche 911 Carrera (PDK) 991.1: which is truly faster?

Off the line, the Cayenne Turbo hits 100 km/h in 4.46 s versus 4.52 s for the 911 Carrera (PDK). The 0.06 s gap is negligible: both vehicles are neck and neck.

At 200 metres, the Cayenne Turbo is doing 149 km/h against 151 km/h for the 911 Carrera (PDK). The gap is 0.00 s. The gap remains stable from the start.

At 400 metres standing start, the 911 Carrera (PDK) crosses the line in 12.54 s versus 12.59 s. The 0.05 s gap represents roughly 3 m of track - barely a car length.

Past 400 metres, the 911 Carrera (PDK) continues to build its lead. At 600 metres, it runs at 209 km/h versus 206 km/h. At 1,000 metres, the 911 Carrera (PDK) finishes in 22.57 s versus 22.79 s, with a 0.21 s lead. Both vehicles have similar top speeds (278 vs 287 km/h), preventing any comeback.

The Cayenne Turbo features all-wheel drive (AWD) against the 911 Carrera (PDK)’s RWD. At low speeds (0-30, 0-50, 0-80 km/h), AWD doubles the driven contact area: all four wheels transmit torque to the road, virtually eliminating wheelspin at launch. This traction advantage is decisive in the range where the motor delivers peak torque, before power and aerodynamics take over.

Both rivals are electronically governed, but not at the same level: the Cayenne Turbo is capped at 278 km/h, the 911 Carrera (PDK) at 287 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 (4.34 kg/hp vs 4.16 kg/hp) and transmission (Automatic vs Automatic).

In European road use (130 km/h max), both vehicles reach the legal speed limit in under 6.61 seconds. The 0.06 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
