The start: 0 to 100 km/h

Off the line, the 911 Carrera S (PDK) hits 100 km/h in 4.14 s versus 4.52 s for the 911 Carrera Cab. At this point, the 911 Carrera S (PDK) leads by 0.38 s and sits roughly 4 m ahead.

From 100 km/h to 400 metres

At 200 metres, the 911 Carrera S (PDK) is doing 156 km/h against 148 km/h for the 911 Carrera Cab. The gap is 0.34 s. The gap remains stable from the start.

At 400 metres standing start, the 911 Carrera S (PDK) crosses the line in 12.09 s versus 12.62 s. The 0.53 s gap represents roughly 27 m of track - two to three car lengths.

Beyond 400 metres: top speed comes into play

Past 400 metres, the 911 Carrera S (PDK) continues to build its lead. At 600 metres, it runs at 217 km/h versus 208 km/h. At 1,000 metres, the 911 Carrera S (PDK) finishes in 21.76 s versus 22.72 s, with a 0.96 s lead. Both vehicles have similar top speeds (297 vs 289 km/h), preventing any comeback.

What the numbers don’t tell you

Both rivals are electronically governed, but not at the same level: the 911 Carrera S (PDK) is capped at 300 km/h, the 911 Carrera Cab at 289 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 (3.73 kg/hp vs 4.29 kg/hp) and transmission (Automatic vs Unknown).

In European road use (130 km/h max), both vehicles reach the legal speed limit in under 6.73 seconds. The 0.38 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
