Off the line, the 911 Carrera Cabriolet hits 100 km/h in 4.43 s versus 5.17 s for the Boxster S. At this point, the 911 Carrera Cabriolet leads by 0.74 s and sits roughly 5 m ahead.
At 200 metres, the 911 Carrera Cabriolet is doing 153 km/h against 141 km/h for the Boxster S. The gap is 0.55 s. The challenger starts to claw back ground.
At 400 metres standing start, the 911 Carrera Cabriolet crosses the line in 12.42 s versus 13.32 s. The 0.90 s gap represents roughly 43 m of track - a gap visible to the naked eye.
Past 400 metres, the 911 Carrera Cabriolet continues to build its lead. At 600 metres, it runs at 214 km/h versus 197 km/h. At 1,000 metres, the 911 Carrera Cabriolet finishes in 22.28 s versus 23.98 s, with a 1.71 s lead.
Both rivals are electronically governed, but not at the same level: the 911 Carrera Cabriolet is capped at 291 km/h, the Boxster S at 274 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 (4.00 kg/hp vs 4.37 kg/hp) and transmission (Automatic vs Unknown).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 7.77 seconds. The 0.74 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Swap one of the two models to explore an equivalent duel in the same segment.
