Porsche Cayman (PDK) 987 vs Porsche Boxster PDK 987: which is truly faster?

Off the line, the Boxster PDK hits 100 km/h in 5.46 s versus 5.58 s for the Cayman (PDK). At this point, the Boxster PDK leads by 0.13 s and sits roughly 2 m ahead.

At 200 metres, the Boxster PDK is doing 137 km/h against 137 km/h for the Cayman (PDK). The gap is 0.06 s. The gap remains stable from the start.

At 400 metres standing start, the Boxster PDK crosses the line in 13.59 s versus 13.65 s. The 0.05 s gap represents roughly 3 m of track - barely a car length.

Past 400 metres, the situation changes. Past 400 metres, both rivals hit the same electronic ceiling at 258 km/h. Neither can claw back ground through top speed - the outcome hinges on the acceleration curve between 100 and 258 km/h.

At 1,000 metres, the Cayman (PDK) finishes in 24.50 s versus 24.54 s. The 0.03 s delta shows an extremely tight race.

On paper, the Cayman (PDK) combines 269 hp, 300 Nm and 1,360 kg - a clear theoretical edge over the Boxster PDK. Yet the Boxster PDK launches quicker. At standstill, both motors deliver peak torque from 0 rpm: the decisive factor is no longer raw power, but available grip. If the Boxster PDK has a better traction coefficient (tyres, weight distribution, traction control calibration), it puts down more force despite inferior specs - exactly what the simulation reflects, calibrated on manufacturer 0-100 km/h times.

Electronically capped at 261 km/h, the Boxster PDK never reaches its natural aerodynamic ceiling in this duel. That’s not a physical limit of the motor - it’s a deliberate manufacturer decision, typically tied to standard-fit tyre ratings or model-range positioning.

With two combustion powertrains, the difference comes down to power-to-weight ratio (5.06 kg/hp vs 5.27 kg/hp) and transmission (Automatic vs Automatic).

In European road use (130 km/h max), both vehicles reach the legal speed limit in under 8.22 seconds. The 0.13 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
