Off the line, the 911 Carrera S Cabriolet hits 100 km/h in 4.17 s versus 4.59 s for the Boxster Spyder. At this point, the 911 Carrera S Cabriolet leads by 0.42 s and sits roughly 2 m ahead.
At 200 metres, the 911 Carrera S Cabriolet is doing 159 km/h against 154 km/h for the Boxster Spyder. The gap is 0.25 s. The challenger starts to claw back ground.
At 400 metres standing start, the 911 Carrera S Cabriolet crosses the line in 12.04 s versus 12.41 s. The 0.37 s gap represents roughly 20 m of track - two to three car lengths.
Past 400 metres, the 911 Carrera S Cabriolet continues to build its lead. At 600 metres, it runs at 221 km/h versus 216 km/h. At 1,000 metres, the 911 Carrera S Cabriolet finishes in 21.49 s versus 22.15 s, with a 0.66 s lead.
Electronically capped at 306 km/h, the 911 Carrera S 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 (3.54 kg/hp vs 3.51 kg/hp) and transmission (Automatic vs Manual).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 6.54 seconds. The 0.42 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
