Off the line, the 911 Carrera S Cabriolet hits 100 km/h in 4.17 s versus 5.07 s for the Boxster S. At this point, the 911 Carrera S Cabriolet leads by 0.90 s and sits roughly 6 m ahead.
At 200 metres, the 911 Carrera S Cabriolet is doing 159 km/h against 143 km/h for the Boxster S. The gap is 0.68 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 13.18 s. The 1.15 s gap represents roughly 55 m of track - a gap visible to the naked eye.
Past 400 metres, the 911 Carrera S Cabriolet continues to build its lead. At 600 metres, it runs at 221 km/h versus 199 km/h. At 1,000 metres, the 911 Carrera S Cabriolet finishes in 21.49 s versus 23.72 s, with a 2.23 s lead.
Both rivals are electronically governed, but not at the same level: the 911 Carrera S Cabriolet is capped at 306 km/h, the Boxster S at 272 km/h. This isn’t a physical engine limit - it’s a manufacturer choice, usually for tyre safety or homologation reasons. Neither car reaches its true aerodynamic top speed.
With two combustion powertrains, the difference comes down to power-to-weight ratio (3.54 kg/hp vs 4.39 kg/hp) and transmission (Automatic vs Automatic).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 7.54 seconds. The 0.90 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
