Off the line, the Bmw 420i Convertible hits 100 km/h in 8.14 s versus 8.51 s for the Bmw 118d. At this point, the Bmw 420i Convertible leads by 0.37 s and sits roughly 6 m ahead.
At 200 metres, the Bmw 420i Convertible is doing 115 km/h against 114 km/h for the Bmw 118d. The gap is 0.23 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 16.27 s. The 0.30 s gap represents roughly 12 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 158 km/h. At 1,000 metres, the Bmw 420i Convertible finishes in 28.97 s versus 29.61 s, with a 0.65 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 118d at 212 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 9.30 kg/hp) and transmission (Automatic vs Automatic).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 13.72 seconds. The 0.37 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.
