Porsche Cayenne Turbo 958.1 vs Porsche Cayman S (Manual) 987: which is truly faster?

Off the line, the Cayenne Turbo hits 100 km/h in 4.46 s versus 4.97 s for the Cayman S (Manual). At this point, the Cayenne Turbo leads by 0.51 s and sits roughly 6 m ahead.

At 200 metres, the Cayenne Turbo is doing 149 km/h against 148 km/h for the Cayman S (Manual). The gap is 0.32 s. The challenger starts to claw back ground.

At 400 metres standing start, the Cayenne Turbo crosses the line in 12.59 s versus 12.90 s. The 0.31 s gap represents roughly 16 m of track - two to three car lengths.

Past 400 metres, the gap narrows. The Cayenne Turbo maxes out at 278 km/h while the Cayman S (Manual) keeps accelerating towards 286 km/h. At 600 metres, the gap has dropped to 0.27 s.

At 1,000 metres, the Cayenne Turbo finishes in 22.79 s versus 22.95 s, with just 0.16 s to spare. The Cayman S (Manual) fails to fully close the launch gap.

The Cayenne Turbo features all-wheel drive (AWD) against the Cayman S (Manual)’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 278 km/h, the Cayenne Turbo 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 (4.34 kg/hp vs 4.22 kg/hp) and transmission (Automatic vs Manual).

In European road use (130 km/h max), both vehicles reach the legal speed limit in under 7.17 seconds. The 0.51 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
