Off the line, the 911 Carrera GTS Cabriolet hits 100 km/h in 4.16 s versus 4.99 s for the Boxster Spyder. At this point, the 911 Carrera GTS Cabriolet leads by 0.83 s and sits roughly 13 m ahead.
At 200 metres, the 911 Carrera GTS Cabriolet is doing 153 km/h against 146 km/h for the Boxster Spyder. The gap is 0.74 s. The gap remains stable from the start.
At 400 metres standing start, the 911 Carrera GTS Cabriolet crosses the line in 12.12 s versus 13.04 s. The 0.92 s gap represents roughly 47 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 207 km/h. At 1,000 metres, the 911 Carrera GTS Cabriolet finishes in 21.83 s versus 23.27 s, with a 1.44 s lead.
Electronically capped at 304 km/h, the 911 Carrera GTS Cabriolet never reaches its natural aerodynamic ceiling in this duel. That’s not a physical limit of the motor - it’s a deliberate manufacturer decision, typically tied to standard-fit tyre ratings or model-range positioning.
With two combustion powertrains, the difference comes down to power-to-weight ratio (3.11 kg/hp vs 3.94 kg/hp) and transmission (Automatic vs Unknown).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 7.16 seconds. The 0.83 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
