The start: 0 to 100 km/h

Off the line, the 718 Cayman GT4 hits 100 km/h in 4.24 s versus 5.16 s for the Panamera S. At this point, the 718 Cayman GT4 leads by 0.92 s and sits roughly 12 m ahead.

From 100 km/h to 400 metres

At 200 metres, the 718 Cayman GT4 is doing 156 km/h against 140 km/h for the Panamera S. The gap is 0.83 s. The gap remains stable from the start.

At 400 metres standing start, the 718 Cayman GT4 crosses the line in 12.02 s versus 13.31 s. The 1.30 s gap represents roughly 62 m of track - a gap visible to the naked eye.

Beyond 400 metres: top speed comes into play

Past 400 metres, the 718 Cayman GT4 continues to build its lead. At 600 metres, it runs at 224 km/h versus 197 km/h. At 1,000 metres, the 718 Cayman GT4 finishes in 21.46 s versus 23.98 s, with a 2.52 s lead.

What the numbers don’t tell you

Both rivals are electronically governed, but not at the same level: the 718 Cayman GT4 is capped at 303 km/h, the Panamera S at 283 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 (3.45 kg/hp vs 4.43 kg/hp) and transmission (Manual vs Automatic).

In European road use (130 km/h max), both vehicles reach the legal speed limit in under 7.71 seconds. The 0.92 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
