Porsche Taycan J1.1 vs Porsche 718 Cayman: which is truly faster?

Off the line, the 718 Cayman hits 100 km/h in 4.56 s versus 5.13 s for the Taycan. Despite lacking instant torque, 300 hp of power compensates. At this point, the 718 Cayman leads by 0.57 s and sits roughly 10 m ahead.

At 200 metres, the 718 Cayman is doing 149 km/h against 148 km/h for the Taycan. The gap is 0.41 s. The challenger starts to claw back ground.

At 400 metres standing start, the 718 Cayman crosses the line in 12.65 s versus 13.02 s. The 0.37 s gap represents roughly 19 m of track - two to three car lengths.

Past 400 metres, the gap narrows. The Taycan maxes out at 230 km/h while the 718 Cayman keeps accelerating towards 274 km/h. At 600 metres, the gap is down to 0.25 s from 0.37 s at 400 metres.

At 1,000 metres, the 718 Cayman finishes in 22.89 s versus 22.91 s, with just 0.02 s to spare. The Taycan fails to fully close the launch gap.

Both rivals are electronically governed, but not at the same level: the Taycan is capped at 230 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.

Instant electric torque gives an advantage off the line. The higher top speed of the combustion engine gives an advantage over longer distances. The distance at which one catches the other depends on the top speed differential.

In European road use (130 km/h max), both vehicles reach the legal speed limit in under 7.04 seconds. The 0.57 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
