The start: 0 to 100 km/h

Off the line, the 2020 911 Carrera S Cabriolet hits 100 km/h in 3.64 s versus 5.72 s for the Boxster. At this point, the 2020 911 Carrera S Cabriolet leads by 2.08 s and sits roughly 15 m ahead.

From 100 km/h to 400 metres

At 200 metres, the 2020 911 Carrera S Cabriolet is doing 161 km/h against 132 km/h for the Boxster. The gap is 1.59 s. The challenger starts to claw back ground.

At 400 metres standing start, the 2020 911 Carrera S Cabriolet crosses the line in 11.58 s versus 13.99 s. The 2.41 s gap represents roughly 106 m of track - a gap visible to the naked eye.

Beyond 400 metres: top speed comes into play

Past 400 metres, the 2020 911 Carrera S Cabriolet continues to build its lead. At 600 metres, it runs at 223 km/h versus 187 km/h. At 1,000 metres, the 2020 911 Carrera S Cabriolet finishes in 21.03 s versus 25.24 s, with a 4.22 s lead.

What the numbers don’t tell you

Both rivals are electronically governed, but not at the same level: the 2020 911 Carrera S Cabriolet is capped at 306 km/h, the Boxster at 262 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 (3.57 kg/hp vs 5.15 kg/hp) and transmission (Automatic vs Unknown).

In European road use (130 km/h max), both vehicles reach the legal speed limit in under 9.00 seconds. The 2.08 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
