Porsche 718 Spyder vs Porsche 911 Carrera Cab 991.1: which is truly faster?

Off the line, the 718 Spyder hits 100 km/h in 4.27 s versus 4.52 s for the 911 Carrera Cab. At this point, the 718 Spyder leads by 0.25 s and sits roughly 4 m ahead.

At 200 metres, the 718 Spyder is doing 156 km/h against 148 km/h for the 911 Carrera Cab. The gap is 0.33 s. The gap remains stable from the start.

At 400 metres standing start, the 718 Spyder crosses the line in 12.04 s versus 12.62 s. The 0.57 s gap represents roughly 29 m of track - two to three car lengths.

Past 400 metres, the 718 Spyder continues to build its lead. At 600 metres, it runs at 224 km/h versus 208 km/h. At 1,000 metres, the 718 Spyder finishes in 21.49 s versus 22.72 s, with a 1.24 s lead.

Electronically capped at 289 km/h, the 911 Carrera Cab 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 (3.46 kg/hp vs 4.29 kg/hp) and transmission (Manual vs Unknown).

In European road use (130 km/h max), both vehicles reach the legal speed limit in under 6.73 seconds. The 0.25 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
