The start: 0 to 100 km/h

Off the line, the 718 Cayman hits 100 km/h in 4.56 s versus 4.63 s for the S3 Sedan. The 0.07 s gap is negligible: both vehicles are neck and neck.

From 100 km/h to 400 metres

At 200 metres, the 718 Cayman is doing 149 km/h against 138 km/h for the S3 Sedan. The gap is 0.16 s. The gap widens compared to the 0-100.

At 400 metres standing start, the 718 Cayman crosses the line in 12.65 s versus 13.08 s. The 0.43 s gap represents roughly 21 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 198 km/h. At 1,000 metres, the 718 Cayman finishes in 22.89 s versus 23.69 s, with a 0.80 s lead.

What the numbers don’t tell you

The S3 Sedan features all-wheel drive (AWD) against the 718 Cayman’s RWD. At low speeds (0-30, 0-50, 0-80 km/h), AWD doubles the driven contact area: all four wheels transmit torque to the road, virtually eliminating wheelspin at launch. This traction advantage is decisive in the range where the motor delivers peak torque, before power and aerodynamics take over.

Both rivals are electronically governed, but not at the same level: the S3 Sedan is capped at 250 (i.e. 155 mph - industry threshold) 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 (4.61 kg/hp vs 4.45 kg/hp) and transmission (Automatic vs Automatic).

In European road use (130 km/h max), both vehicles reach the legal speed limit in under 7.68 seconds. The 0.07 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
