Off the line, the Bmw 420i Convertible hits 100 km/h in 8.14 s versus 8.92 s for the Bmw 218d xDrive. At this point, the Bmw 420i Convertible leads by 0.78 s and sits roughly 15 m ahead.
At 200 metres, the Bmw 420i Convertible is doing 115 km/h against 113 km/h for the Bmw 218d xDrive. The gap is 0.59 s. The challenger starts to claw back ground.
At 400 metres standing start, the Bmw 420i Convertible crosses the line in 15.96 s versus 16.67 s. The 0.71 s gap represents roughly 27 m of track — two to three car lengths.
Past 400 metres, the Bmw 420i Convertible continues to build its lead. At 600 metres, it runs at 161 km/h versus 157 km/h. At 1,000 metres, the Bmw 420i Convertible finishes in 28.97 s versus 30.09 s, with a 1.12 s lead.
Both rivals are electronically governed, but not at the same level: the Bmw 420i Convertible is capped at 236 km/h, the Bmw 218d xDrive at 209 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 (9.18 kg/hp vs 10.13 kg/hp) and transmission (Automatic vs Automatic).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 14.27 seconds. The 0.78 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.
