Porsche Cayenne Turbo Coupe vs Porsche Cayman S PDK: which is truly faster?

Off the line, the Cayenne Turbo Coupe hits 100 km/h in 3.84 s versus 4.67 s for the Cayman S PDK. At this point, the Cayenne Turbo Coupe leads by 0.83 s and sits roughly 14 m ahead.

At 200 metres, the Cayenne Turbo Coupe is doing 150 km/h against 151 km/h for the Cayman S PDK. The gap is 0.60 s. The challenger starts to claw back ground.

At 400 metres standing start, the Cayenne Turbo Coupe crosses the line in 12.07 s versus 12.60 s. The 0.52 s gap represents roughly 27 m of track - two to three car lengths.

Past 400 metres, the gap narrows.

At 1,000 metres, the Cayenne Turbo Coupe finishes in 22.22 s versus 22.56 s, with just 0.33 s to spare. The Cayman S PDK fails to fully close the launch gap.

The Cayenne Turbo Coupe 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 285 km/h, the Cayenne Turbo Coupe 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 (4.38 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 6.63 seconds. The 0.83 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
