Porsche Cayenne Turbo S 958.2 vs Porsche Cayman S (PDK) 987: which is truly faster?

Off the line, the Cayenne Turbo S hits 100 km/h in 3.96 s versus 4.83 s for the Cayman S (PDK). At this point, the Cayenne Turbo S leads by 0.87 s and sits roughly 12 m ahead.

At 200 metres, the Cayenne Turbo S is doing 152 km/h against 149 km/h for the Cayman S (PDK). The gap is 0.61 s. The challenger starts to claw back ground.

At 400 metres standing start, the Cayenne Turbo S crosses the line in 12.11 s versus 12.79 s. The 0.67 s gap represents roughly 34 m of track - a gap visible to the naked eye.

Past 400 metres, the Cayenne Turbo S continues to build its lead. At 600 metres, it runs at 211 km/h versus 209 km/h. At 1,000 metres, the Cayenne Turbo S finishes in 22.13 s versus 22.86 s, with a 0.73 s lead. Both vehicles have similar top speeds (283 vs 283 km/h), preventing any comeback.

The Cayenne Turbo S 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 283 km/h, the Cayenne Turbo S 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 (3.92 kg/hp vs 4.30 kg/hp) and transmission (Unknown vs Automatic).

In European road use (130 km/h max), both vehicles reach the legal speed limit in under 6.90 seconds. The 0.87 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
