Off the line, the 911 Carrera S Cabriolet hits 100 km/h in 4.17 s versus 4.65 s for the 718 Boxster. At this point, the 911 Carrera S Cabriolet leads by 0.47 s and sits roughly 2 m ahead.
At 200 metres, the 911 Carrera S Cabriolet is doing 159 km/h against 147 km/h for the 718 Boxster. The gap is 0.38 s. The gap remains stable from the start.
At 400 metres standing start, the 911 Carrera S Cabriolet crosses the line in 12.04 s versus 12.76 s. The 0.72 s gap represents roughly 36 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 204 km/h. At 1,000 metres, the 911 Carrera S Cabriolet finishes in 21.49 s versus 23.08 s, with a 1.59 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 718 Boxster 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 (3.54 kg/hp vs 4.45 kg/hp) and transmission (Automatic vs Automatic).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 6.84 seconds. The 0.47 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.
