Off the line, the 911 Carrera Cabriolet hits 100 km/h in 4.43 s versus 4.75 s for the Boxster Spyder. At this point, the 911 Carrera Cabriolet leads by 0.32 s and sits roughly 3 m ahead.
At 200 metres, the 911 Carrera Cabriolet is doing 153 km/h against 148 km/h for the Boxster Spyder. The gap is 0.26 s. The gap remains stable from the start.
At 400 metres standing start, the 911 Carrera Cabriolet crosses the line in 12.42 s versus 12.80 s. The 0.39 s gap represents roughly 20 m of track - two to three car lengths.
Past 400 metres, the 911 Carrera Cabriolet continues to build its lead. At 600 metres, it runs at 214 km/h versus 206 km/h. At 1,000 metres, the 911 Carrera Cabriolet finishes in 22.28 s versus 22.97 s, with a 0.70 s lead. Both vehicles have similar top speeds (286 vs 272 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 (4.00 kg/hp vs 3.98 kg/hp) and transmission (Automatic vs Unknown).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 7.05 seconds. The 0.32 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
