The start: 0 to 100 km/h

Off the line, the 911 GT3 hits 100 km/h in 4.08 s versus 4.17 s for the 718 Cayman S. The 0.09 s gap is negligible: both vehicles are neck and neck.

From 100 km/h to 400 metres

At 200 metres, the 911 GT3 is doing 158 km/h against 156 km/h for the 718 Cayman S. The gap is 0.17 s. The gap widens compared to the 0-100.

At 400 metres standing start, the 911 GT3 crosses the line in 11.85 s versus 12.12 s. The 0.27 s gap represents roughly 14 m of track - two to three car lengths.

Beyond 400 metres: top speed comes into play

Past 400 metres, the 911 GT3 continues to build its lead. At 600 metres, it runs at 225 km/h versus 215 km/h. At 1,000 metres, the 911 GT3 finishes in 21.23 s versus 21.89 s, with a 0.66 s lead.

What the numbers don’t tell you

Electronically capped at 285 km/h, the 718 Cayman 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 (3.16 kg/hp vs 3.87 kg/hp) and transmission (Manual vs Automatic).

In European road use (130 km/h max), both vehicles reach the legal speed limit in under 6.01 seconds. The 0.09 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
