Porsche Cayenne S Coupe E3.1 vs Porsche Cayman S 981: which is truly faster?

Off the line, the Cayenne S Coupe hits 100 km/h in 4.61 s versus 4.90 s for the Cayman S. At this point, the Cayenne S Coupe leads by 0.28 s and sits roughly 7 m ahead.

At 200 metres, the Cayenne S Coupe is doing 144 km/h against 147 km/h for the Cayman S. The gap is 0.22 s. The gap remains stable from the start.

At 400 metres standing start, the Cayenne S Coupe crosses the line in 12.80 s versus 12.90 s. The 0.10 s gap represents roughly 5 m of track - barely a car length.

Past 400 metres, the situation changes. The Cayenne S Coupe maxes out at 262 km/h while the Cayman S keeps accelerating towards 278 km/h. At 600 metres, the gap has dropped to 0.01 s.

Around 613 metres, both vehicles are level. This is the inversion point: the Cayman S overcomes its launch deficit thanks to a 16 km/h higher top speed.

At 1,000 metres, the Cayman S finishes in 23.17 s versus 23.34 s. The 0.17 s delta shows an extremely tight race.

The Cayenne S Coupe features all-wheel drive (AWD) against the Cayman S’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 262 km/h, the Cayenne S 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 (5.10 kg/hp vs 4.00 kg/hp) and transmission (Unknown vs Unknown).

In European road use (130 km/h max), both vehicles reach the legal speed limit in under 7.04 seconds. The 0.28 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
