Off the line, the 911 Carrera 4S Cabriolet hits 100 km/h in 4.05 s versus 4.08 s for the 911 GT3. The 0.03 s gap is negligible: both vehicles are neck and neck.
At 200 metres, the 911 GT3 is doing 158 km/h against 158 km/h for the 911 Carrera 4S Cabriolet. The gap is 0.08 s. The gap remains stable from the start.
At 400 metres standing start, the 911 GT3 crosses the line in 11.85 s versus 11.98 s. The 0.12 s gap represents roughly 7 m of track - barely a car length.
Past 400 metres, the 911 GT3 continues to build its lead. At 600 metres, it runs at 225 km/h versus 220 km/h. At 1,000 metres, the 911 GT3 finishes in 21.23 s versus 21.53 s, with a 0.29 s lead. Both vehicles have similar top speeds (313 vs 303 km/h), preventing any comeback.
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 (3.16 kg/hp vs 3.66 kg/hp) and transmission (Manual vs Automatic).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 5.85 seconds. The 0.03 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
