Off the line, the Bmw 430i Convertible hits 100 km/h in 6.24 s versus 7.15 s for the Bmw 120d. At this point, the Bmw 430i Convertible leads by 0.91 s and sits roughly 18 m ahead.
At 200 metres, the Bmw 430i Convertible is doing 127 km/h against 124 km/h for the Bmw 120d. The gap is 0.74 s. The challenger starts to claw back ground.
At 400 metres standing start, the Bmw 430i Convertible crosses the line in 14.45 s versus 15.30 s. The 0.85 s gap represents roughly 36 m of track - a gap visible to the naked eye.
Past 400 metres, the Bmw 430i Convertible continues to build its lead. At 600 metres, it runs at 177 km/h versus 172 km/h. At 1,000 metres, the Bmw 430i Convertible finishes in 26.31 s versus 27.53 s, with a 1.23 s lead.
Both rivals are electronically governed, but not at the same level: the Bmw 430i Convertible is capped at 250 (i.e. 155 mph - industry threshold) km/h, the Bmw 120d at 228 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 (6.65 kg/hp vs 7.45 kg/hp) and transmission (Automatic vs Automatic).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 10.99 seconds. The 0.91 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Over 0–100 km/h, 430i Convertible G22 wins (6,24 s vs 7,15 s).
