Off the line, the 911 Carrera S Cabriolet hits 100 km/h in 4.17 s versus 4.27 s for the 718 Spyder. The 0.09 s gap is negligible: both vehicles are neck and neck.
At 200 metres, the 718 Spyder is doing 156 km/h against 159 km/h for the 911 Carrera S Cabriolet. The gap is 0.04 s. The gap remains stable from the start.
At 400 metres standing start, the 911 Carrera S Cabriolet crosses the line in 12.04 s versus 12.04 s. The 0.00 s gap represents roughly 0 m of track
Past 400 metres, nothing changes. Same ceiling, same acceleration, same trajectory - both rivals run in formation to the line. The 0.00 s gap at 1,000 metres confirms what the specs already suggested: on track, they’re interchangeable. The real contest happens elsewhere - range, comfort, charging network reliability.
Electronically capped at 306 km/h, the 911 Carrera S 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 (3.54 kg/hp vs 3.46 kg/hp) and transmission (Automatic vs Manual).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 5.91 seconds. The 0.09 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
