Off the line, the 911 Carrera 4 hits 100 km/h in 4.90 s versus 4.90 s for the Cayman S. The 0.00 s gap is negligible: both vehicles are neck and neck.
At 200 metres, the 911 Carrera 4 is doing 147 km/h against 147 km/h for the Cayman S. The gap is 0.00 s. The gap remains stable from the start.
At 400 metres standing start, the 911 Carrera 4 crosses the line in 12.85 s versus 12.90 s. The 0.05 s gap represents roughly 2 m of track - barely a car length.
Past 400 metres, the 911 Carrera 4 continues to build its lead. At 600 metres, it runs at 209 km/h versus 205 km/h. At 1,000 metres, the 911 Carrera 4 finishes in 22.96 s versus 23.17 s, with a 0.21 s lead. Both vehicles have similar top speeds (285 vs 278 km/h), preventing any comeback.
The 911 Carrera 4 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 285 km/h, the 911 Carrera 4 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 (4.03 kg/hp vs 4.00 kg/hp) and transmission (Manual vs Unknown).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 7.15 seconds. The 0.00 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
