Off the line, the 911 Carrera GTS Cabriolet hits 100 km/h in 4.16 s versus 5.72 s for the Boxster. At this point, the 911 Carrera GTS Cabriolet leads by 1.56 s and sits roughly 13 m ahead.
At 200 metres, the 911 Carrera GTS Cabriolet is doing 153 km/h against 132 km/h for the Boxster. The gap is 1.19 s. The challenger starts to claw back ground.
At 400 metres standing start, the 911 Carrera GTS Cabriolet crosses the line in 12.12 s versus 13.99 s. The 1.88 s gap represents roughly 83 m of track - a gap visible to the naked eye.
Past 400 metres, the 911 Carrera GTS Cabriolet continues to build its lead. At 600 metres, it runs at 217 km/h versus 187 km/h. At 1,000 metres, the 911 Carrera GTS Cabriolet finishes in 21.83 s versus 25.24 s, with a 3.42 s lead.
Both rivals are electronically governed, but not at the same level: the 911 Carrera GTS Cabriolet is capped at 304 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 (3.11 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 1.56 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Over 0–100 km/h, 911 Carrera GTS Cabriolet 991.1 wins (4,16 s vs 5,71 s).
