Off the line, the Cayman GT4 hits 100 km/h in 3.95 s versus 4.43 s for the 911 Carrera Cabriolet. At this point, the Cayman GT4 leads by 0.47 s and sits roughly 10 m ahead.
At 200 metres, the Cayman GT4 is doing 155 km/h against 153 km/h for the 911 Carrera Cabriolet. The gap is 0.45 s. The gap remains stable from the start.
At 400 metres standing start, the Cayman GT4 crosses the line in 11.90 s versus 12.42 s. The 0.52 s gap represents roughly 27 m of track - two to three car lengths.
Past 400 metres, the Cayman GT4 continues to build its lead. At 600 metres, it runs at 218 km/h versus 214 km/h. At 1,000 metres, the Cayman GT4 finishes in 21.59 s versus 22.28 s, with a 0.68 s lead. Both vehicles have similar top speeds (295 vs 286 km/h), preventing any comeback.
Electronically capped at 291 km/h, the 911 Carrera 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 (3.48 kg/hp vs 4.00 kg/hp) and transmission (Manual vs Automatic).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 6.39 seconds. The 0.47 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
