Off the line, the 911 Carrera 4S Cabriolet hits 100 km/h in 4.05 s versus 5.52 s for the Cayman. At this point, the 911 Carrera 4S Cabriolet leads by 1.47 s and sits roughly 9 m ahead.
At 200 metres, the 911 Carrera 4S Cabriolet is doing 158 km/h against 136 km/h for the Cayman. The gap is 1.03 s. The challenger starts to claw back ground.
At 400 metres standing start, the 911 Carrera 4S Cabriolet crosses the line in 11.98 s versus 13.64 s. The 1.66 s gap represents roughly 76 m of track - a gap visible to the naked eye.
Past 400 metres, the 911 Carrera 4S Cabriolet continues to build its lead. At 600 metres, it runs at 220 km/h versus 190 km/h. At 1,000 metres, the 911 Carrera 4S Cabriolet finishes in 21.53 s versus 24.68 s, with a 3.15 s lead.
The 911 Carrera 4S Cabriolet features all-wheel drive (AWD) against the Cayman’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 303 km/h, the 911 Carrera 4S Cabriolet 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 (3.66 kg/hp vs 4.70 kg/hp) and transmission (Automatic vs Unknown).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 8.30 seconds. The 1.47 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Over 0–100 km/h, 911 Carrera 4S Cabriolet 991.2 wins (4,04 s vs 5,52 s).
