The start: 0 to 100 km/h

Off the line, the 718 Cayman GTS hits 100 km/h in 4.47 s versus 4.90 s for the 911 Carrera 4. At this point, the 718 Cayman GTS leads by 0.43 s and sits roughly 5 m ahead.

From 100 km/h to 400 metres

At 200 metres, the 718 Cayman GTS is doing 155 km/h against 147 km/h for the 911 Carrera 4. The gap is 0.36 s. The gap remains stable from the start.

At 400 metres standing start, the 718 Cayman GTS crosses the line in 12.32 s versus 12.85 s. The 0.54 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 718 Cayman GTS continues to build its lead. At 600 metres, it runs at 217 km/h versus 209 km/h. At 1,000 metres, the 718 Cayman GTS finishes in 21.96 s versus 22.96 s, with a 1.00 s lead. Both vehicles have similar top speeds (290 vs 285 km/h), preventing any comeback.

What the numbers don’t tell you

Both rivals are electronically governed, but not at the same level: the 718 Cayman GTS is capped at 290 km/h, the 911 Carrera 4 at 285 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 (3.77 kg/hp vs 4.03 kg/hp) and transmission (Manual vs Manual).

In European road use (130 km/h max), both vehicles reach the legal speed limit in under 7.15 seconds. The 0.43 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
