Off the line, the Cayman S hits 100 km/h in 4.90 s versus 8.14 s for the Bmw 420i Convertible. At this point, the Cayman S leads by 3.25 s and sits roughly 19 m ahead.
At 200 metres, the Cayman S is doing 147 km/h against 115 km/h for the Bmw 420i Convertible. The gap is 1.86 s. The challenger starts to claw back ground.
At 400 metres standing start, the Cayman S crosses the line in 12.90 s versus 15.96 s. The 3.06 s gap represents roughly 116 m of track - a gap visible to the naked eye.
Past 400 metres, the Cayman S continues to build its lead. At 600 metres, it runs at 205 km/h versus 161 km/h. At 1,000 metres, the Cayman S finishes in 23.17 s versus 28.97 s, with a 5.79 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 (4.00 kg/hp vs 9.18 kg/hp) and transmission (Unknown vs Automatic).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 13.10 seconds. The 3.25 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Over 0–100 km/h, Cayman S 981 wins (4,89 s vs 8,14 s).
