Off the line, the Cayman (Manual) hits 100 km/h in 5.65 s versus 7.75 s for the Bmw 420d Convertible. At this point, the Cayman (Manual) leads by 2.10 s and sits roughly 10 m ahead.
At 200 metres, the Cayman (Manual) is doing 135 km/h against 116 km/h for the Bmw 420d Convertible. The gap is 0.97 s. The challenger starts to claw back ground.
At 400 metres standing start, the Cayman (Manual) crosses the line in 13.79 s versus 15.64 s. The 1.85 s gap represents roughly 72 m of track — a gap visible to the naked eye.
Past 400 metres, the Cayman (Manual) continues to build its lead. At 600 metres, it runs at 193 km/h versus 161 km/h. At 1,000 metres, the Cayman (Manual) finishes in 24.69 s versus 28.69 s, with a 4.00 s lead.
Electronically capped at 236 km/h, the Bmw 420d 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 (4.94 kg/hp vs 9.34 kg/hp) and transmission (Manual vs Automatic).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 12.82 seconds. The 2.10 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
