The start: 0 to 100 km/h

Off the line, the 718 Cayman hits 100 km/h in 4.56 s versus 6.93 s for the Dolphin Boost 150kW. Despite lacking instant torque, 300 hp of power compensates. At this point, the 718 Cayman leads by 2.37 s and sits roughly 22 m ahead.

From 100 km/h to 400 metres

At 200 metres, the 718 Cayman is doing 149 km/h against 126 km/h for the Dolphin Boost 150kW. The gap is 1.68 s. The challenger starts to claw back ground.

At 400 metres standing start, the 718 Cayman crosses the line in 12.65 s versus 15.13 s. The 2.48 s gap represents roughly 102 m of track - a gap visible to the naked eye.

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 160 km/h. At 1,000 metres, the 718 Cayman finishes in 22.89 s versus 28.66 s, with a 5.77 s lead.

What the numbers don’t tell you

Both rivals are electronically governed, but not at the same level: the 718 Cayman is capped at 274 km/h, the Dolphin Boost 150kW at 160 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 10.58 seconds. The 2.37 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
