Off the line, the Cayman hits 100 km/h in 5.52 s versus 6.24 s for the Bmw 430i Convertible. At this point, the Cayman leads by 0.72 s and sits roughly 5 m ahead.
At 200 metres, the Cayman is doing 136 km/h against 127 km/h for the Bmw 430i Convertible. The gap is 0.45 s. The challenger starts to claw back ground.
At 400 metres standing start, the Cayman crosses the line in 13.64 s versus 14.45 s. The 0.81 s gap represents roughly 35 m of track - a gap visible to the naked eye.
Past 400 metres, the Cayman continues to build its lead. At 600 metres, it runs at 190 km/h versus 177 km/h. At 1,000 metres, the Cayman finishes in 24.68 s versus 26.31 s, with a 1.62 s lead. Both vehicles have similar top speeds (253 vs 250 (i.e. 155 mph - industry threshold) km/h), preventing any comeback.
Electronically capped at 250 (i.e. 155 mph - industry threshold) km/h, the Bmw 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 (4.70 kg/hp vs 6.65 kg/hp) and transmission (Unknown vs Automatic).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 9.87 seconds. The 0.72 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Swap one of the two models to explore an equivalent duel in the same segment.
