The start: 0 to 100 km/h

Off the line, the 718 Cayman hits 100 km/h in 4.56 s versus 4.94 s for the Boxster S. At this point, the 718 Cayman leads by 0.38 s and sits roughly 4 m ahead.

From 100 km/h to 400 metres

At 200 metres, the 718 Cayman is doing 149 km/h against 145 km/h for the Boxster S. The gap is 0.26 s. The challenger starts to claw back ground.

At 400 metres standing start, the 718 Cayman crosses the line in 12.65 s versus 13.01 s. The 0.36 s gap represents roughly 18 m of track - two to three car lengths.

Beyond 400 metres: top speed comes into play

Past 400 metres, the 718 Cayman continues to build its lead. At 600 metres, it runs at 206 km/h versus 202 km/h. At 1,000 metres, the 718 Cayman finishes in 22.89 s versus 23.47 s, with a 0.58 s lead. Both vehicles have similar top speeds (273 vs 274 km/h), preventing any comeback.

What the numbers don’t tell you

Both rivals are electronically governed, but not at the same level: the Boxster S is capped at 279 km/h, the 718 Cayman at 274 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 (4.14 kg/hp vs 4.45 kg/hp) and transmission (Unknown vs Automatic).

In European road use (130 km/h max), both vehicles reach the legal speed limit in under 7.23 seconds. The 0.38 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
