Manufacturer technical specifications. The power-to-weight ratio is the key physical factor in a drag race.

The start: 0 to 100 km/h

Off the line, the 718 Cayman S hits 100 km/h in 4.17 s versus 4.44 s for the 911 Carrera S. At this point, the 718 Cayman S leads by 0.27 s and sits roughly 3 m ahead.

From 100 km/h to 400 metres

At 200 metres, the 718 Cayman S is doing 156 km/h against 154 km/h for the 911 Carrera S. The gap is 0.18 s. The gap remains stable from the start.

At 400 metres standing start, the 718 Cayman S crosses the line in 12.12 s versus 12.30 s. The 0.18 s gap represents roughly 10 m of track - barely a car length.

Beyond 400 metres: top speed comes into play

Past 400 metres, the gap narrows. The 718 Cayman S maxes out at 285 km/h while the 911 Carrera S keeps accelerating towards 303 km/h. At 600 metres, the gap has dropped to 0.14 s.

At 1,000 metres, the 718 Cayman S finishes in 21.89 s versus 21.94 s, with just 0.04 s to spare. The 911 Carrera S fails to fully close the launch gap.

What the numbers don’t tell you

Both rivals are electronically governed, but not at the same level: the 911 Carrera S is capped at 303 km/h, the 718 Cayman S 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 (3.44 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 6.41 seconds. The 0.27 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
