The start: 0 to 100 km/h

Off the line, the 911 Carrera S hits 100 km/h in 3.93 s versus 3.98 s for the 718 Boxster GTS PDK. The 0.05 s gap is negligible: both vehicles are neck and neck.

From 100 km/h to 400 metres

At 200 metres, the 911 Carrera S is doing 162 km/h against 159 km/h for the 718 Boxster GTS PDK. The gap is 0.04 s. The gap remains stable from the start.

At 400 metres standing start, the 911 Carrera S crosses the line in 11.77 s versus 11.88 s. The 0.11 s gap represents roughly 6 m of track - barely a car length.

Beyond 400 metres: top speed comes into play

Past 400 metres, the 911 Carrera S continues to build its lead. At 600 metres, it runs at 225 km/h versus 221 km/h. At 1,000 metres, the 911 Carrera S finishes in 21.09 s versus 21.39 s, with a 0.30 s lead.

What the numbers don’t tell you

Both rivals are electronically governed, but not at the same level: the 911 Carrera S is capped at 307 km/h, the 718 Boxster GTS PDK at 290 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 (3.38 kg/hp vs 3.85 kg/hp) and transmission (Automatic vs Automatic).

In European road use (130 km/h max), both vehicles reach the legal speed limit in under 5.71 seconds. The 0.05 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
