The start: 0 to 100 km/h

Off the line, the 718 Boxster S hits 100 km/h in 4.16 s versus 4.43 s for the 911 Carrera Cabriolet. At this point, the 718 Boxster S leads by 0.26 s and sits roughly 4 m ahead.

From 100 km/h to 400 metres

At 200 metres, the 718 Boxster S is doing 157 km/h against 153 km/h for the 911 Carrera Cabriolet. The gap is 0.25 s. The gap remains stable from the start.

At 400 metres standing start, the 718 Boxster S crosses the line in 12.06 s versus 12.42 s. The 0.36 s gap represents roughly 19 m of track — two to three car lengths.

Beyond 400 metres: top speed comes into play

Past 400 metres, the 718 Boxster S continues to build its lead. At 600 metres, it runs at 218 km/h versus 214 km/h. At 1,000 metres, the 718 Boxster S finishes in 21.69 s versus 22.28 s, with a 0.58 s lead. Both vehicles have similar top speeds (286 vs 285 km/h), preventing any comeback.

What the numbers don’t tell you

Both rivals are electronically governed, but not at the same level: the 911 Carrera Cabriolet is capped at 291 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 (4.00 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 6.39 seconds. The 0.26 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
