The start: 0 to 100 km/h

Off the line, the Cayman PDK hits 100 km/h in 5.28 s versus 6.24 s for the 430i Convertible. At this point, the Cayman PDK leads by 0.96 s and sits roughly 6 m ahead.

From 100 km/h to 400 metres

At 200 metres, the Cayman PDK is doing 140 km/h against 127 km/h for the 430i Convertible. The gap is 0.58 s. The challenger starts to claw back ground.

At 400 metres standing start, the Cayman PDK crosses the line in 13.38 s versus 14.45 s. The 1.07 s gap represents roughly 46 m of track - a gap visible to the naked eye.

Beyond 400 metres: top speed comes into play

Past 400 metres, the Cayman PDK continues to build its lead. At 600 metres, it runs at 196 km/h versus 177 km/h. At 1,000 metres, the Cayman PDK finishes in 24.10 s versus 26.31 s, with a 2.21 s lead. Both vehicles have similar top speeds (262 vs 250 (i.e. 155 mph - industry threshold) km/h), preventing any comeback.

What the numbers don’t tell you

Electronically capped at 250 (i.e. 155 mph - industry threshold) km/h, the 430i 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 6.65 kg/hp) and transmission (Automatic vs Automatic).

In European road use (130 km/h max), both vehicles reach the legal speed limit in under 9.87 seconds. The 0.96 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
