Off the line, the Cayman (PDK) hits 100 km/h in 5.58 s versus 8.14 s for the Bmw 420i Convertible. At this point, the Cayman (PDK) leads by 2.56 s and sits roughly 17 m ahead.
At 200 metres, the Cayman (PDK) is doing 137 km/h against 115 km/h for the Bmw 420i Convertible. The gap is 1.39 s. The challenger starts to claw back ground.
At 400 metres standing start, the Cayman (PDK) crosses the line in 13.65 s versus 15.96 s. The 2.31 s gap represents roughly 89 m of track — a gap visible to the naked eye.
Past 400 metres, the Cayman (PDK) continues to build its lead. At 600 metres, it runs at 194 km/h versus 161 km/h. At 1,000 metres, the Cayman (PDK) finishes in 24.50 s versus 28.97 s, with a 4.46 s lead.
Electronically capped at 236 km/h, the Bmw 420i Convertible 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 9.18 kg/hp) and transmission (Automatic vs Automatic).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 13.10 seconds. The 2.56 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
