Porsche 911 Carrera Cab 991.1 vs Porsche Cayman S PDK 987: which is truly faster?

Off the line, the 911 Carrera Cab hits 100 km/h in 4.52 s versus 4.67 s for the Cayman S PDK. At this point, the 911 Carrera Cab leads by 0.16 s and sits roughly 3 m ahead.

At 200 metres, the 911 Carrera Cab is doing 148 km/h against 151 km/h for the Cayman S PDK. The gap is 0.06 s. The gap remains stable from the start.

At 400 metres standing start, the Cayman S PDK crosses the line in 12.60 s versus 12.62 s. The 0.02 s gap represents roughly 1 m of track

Past 400 metres, the Cayman S PDK continues to build its lead. At 600 metres, it runs at 212 km/h versus 208 km/h. At 1,000 metres, the Cayman S PDK finishes in 22.56 s versus 22.72 s, with a 0.17 s lead. Both vehicles have similar top speeds (289 vs 286 km/h), preventing any comeback.

The 911 Carrera Cab features all-wheel drive (AWD) against the Cayman S 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.

Electronically capped at 289 km/h, the 911 Carrera Cab never reaches its natural aerodynamic ceiling in this duel. That’s not a physical limit of the motor — it’s a deliberate manufacturer decision, typically tied to standard-fit tyre ratings or model-range positioning.

With two combustion powertrains, the difference comes down to power-to-weight ratio (4.29 kg/hp vs 4.24 kg/hp) and transmission (Unknown vs Automatic).

In European road use (130 km/h max), both vehicles reach the legal speed limit in under 6.73 seconds. The 0.16 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
