The start: 0 to 100 km/h

Off the line, the 2019 911 Speedster hits 100 km/h in 3.92 s versus 4.56 s for the 718 Cayman. At this point, the 2019 911 Speedster leads by 0.64 s and sits roughly 8 m ahead.

From 100 km/h to 400 metres

At 200 metres, the 2019 911 Speedster is doing 164 km/h against 149 km/h for the 718 Cayman. The gap is 0.64 s. The gap remains stable from the start.

At 400 metres standing start, the 2019 911 Speedster crosses the line in 11.61 s versus 12.65 s. The 1.05 s gap represents roughly 52 m of track - a gap visible to the naked eye.

Beyond 400 metres: top speed comes into play

Past 400 metres, the 2019 911 Speedster continues to build its lead. At 600 metres, it runs at 230 km/h versus 206 km/h. At 1,000 metres, the 2019 911 Speedster finishes in 20.68 s versus 22.89 s, with a 2.21 s lead.

What the numbers don’t tell you

Both rivals are electronically governed, but not at the same level: the 2019 911 Speedster is capped at 309 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 (2.88 kg/hp vs 4.45 kg/hp) and transmission (Manual vs Automatic).

In European road use (130 km/h max), both vehicles reach the legal speed limit in under 6.70 seconds. The 0.64 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
