The start: 0 to 100 km/h

Off the line, the 911 Carrera GTS hits 100 km/h in 3.65 s versus 4.90 s for the Cayman S. At this point, the 911 Carrera GTS leads by 1.25 s and sits roughly 11 m ahead.

From 100 km/h to 400 metres

At 200 metres, the 911 Carrera GTS is doing 166 km/h against 147 km/h for the Cayman S. The gap is 1.00 s. The challenger starts to claw back ground.

At 400 metres standing start, the 911 Carrera GTS crosses the line in 11.41 s versus 12.90 s. The 1.49 s gap represents roughly 73 m of track - a gap visible to the naked eye.

Beyond 400 metres: top speed comes into play

Past 400 metres, the 911 Carrera GTS continues to build its lead. At 600 metres, it runs at 230 km/h versus 205 km/h. At 1,000 metres, the 911 Carrera GTS finishes in 20.49 s versus 23.17 s, with a 2.68 s lead.

What the numbers don’t tell you

Electronically capped at 311 km/h, the 911 Carrera GTS 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 (3.02 kg/hp vs 4.00 kg/hp) and transmission (Automatic vs Unknown).

In European road use (130 km/h max), both vehicles reach the legal speed limit in under 7.04 seconds. The 1.25 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
