Off the line, the 718 Cayman hits 100 km/h in 4.56 s versus 8.14 s for the Bmw 420i Convertible. At this point, the 718 Cayman leads by 3.58 s and sits roughly 20 m ahead.
At 200 metres, the 718 Cayman is doing 149 km/h against 115 km/h for the Bmw 420i Convertible. The gap is 2.07 s. The challenger starts to claw back ground.
At 400 metres standing start, the 718 Cayman crosses the line in 12.65 s versus 15.96 s. The 3.31 s gap represents roughly 125 m of track — a gap visible to the naked eye.
Past 400 metres, the 718 Cayman continues to build its lead. At 600 metres, it runs at 206 km/h versus 161 km/h. At 1,000 metres, the 718 Cayman finishes in 22.89 s versus 28.97 s, with a 6.08 s lead.
Both rivals are electronically governed, but not at the same level: the 718 Cayman is capped at 274 km/h, the Bmw 420i Convertible at 236 km/h. This isn’t a physical engine limit — it’s a manufacturer choice, usually for tyre safety or homologation reasons. Neither car reaches its true aerodynamic top speed.
With two combustion powertrains, the difference comes down to power-to-weight ratio (4.45 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 3.58 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.
