Porsche 911 R 991.2 vs Porsche 911 Carrera S 991.2: which is truly faster?

Off the line, the 911 R hits 100 km/h in 3.78 s versus 3.93 s for the 911 Carrera S. At this point, the 911 R leads by 0.15 s and sits roughly 4 m ahead.

At 200 metres, the 911 R is doing 166 km/h against 162 km/h for the 911 Carrera S. The gap is 0.23 s. The gap remains stable from the start.

At 400 metres standing start, the 911 R crosses the line in 11.38 s versus 11.77 s. The 0.39 s gap represents roughly 22 m of track - two to three car lengths.

Past 400 metres, the 911 R continues to build its lead. At 600 metres, it runs at 239 km/h versus 225 km/h. At 1,000 metres, the 911 R finishes in 20.19 s versus 21.09 s, with a 0.89 s lead.

Electronically capped at 307 km/h, the 911 Carrera S 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 (2.74 kg/hp vs 3.38 kg/hp) and transmission (Manual vs Automatic).

In European road use (130 km/h max), both vehicles reach the legal speed limit in under 5.59 seconds. The 0.15 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
