Off the line, the 718 Boxster S hits 100 km/h in 4.16 s versus 4.17 s for the 911 Carrera S Cabriolet. The 0.01 s gap is negligible: both vehicles are neck and neck.
At 200 metres, the 718 Boxster S is doing 157 km/h against 159 km/h for the 911 Carrera S Cabriolet. The gap is 0.04 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 12.06 s. The 0.02 s gap represents roughly 1 m of track
Past 400 metres, the 911 Carrera S Cabriolet continues to build its lead. At 600 metres, it runs at 221 km/h versus 218 km/h. At 1,000 metres, the 911 Carrera S Cabriolet finishes in 21.49 s versus 21.69 s, with a 0.21 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 S at 285 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 3.87 kg/hp) and transmission (Automatic vs Automatic).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 5.93 seconds. The 0.01 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
