Off the line, the 430i Convertible hits 100 km/h in 6.24 s versus 6.48 s for the 125d. At this point, the 430i Convertible leads by 0.24 s and sits roughly 11 m ahead.
At 200 metres, the 430i Convertible is doing 127 km/h against 130 km/h for the 125d. The gap is 0.33 s. The gap remains stable from the start.
At 400 metres standing start, the 430i Convertible crosses the line in 14.45 s versus 14.67 s. The 0.22 s gap represents roughly 10 m of track - two to three car lengths.
Past 400 metres, the gap narrows. The 125d maxes out at 240 km/h while the 430i Convertible keeps accelerating towards 250 (i.e. 155 mph - industry threshold) km/h. At 600 metres, the gap has dropped to 0.15 s.
At 1,000 metres, the 430i Convertible finishes in 26.31 s versus 26.39 s, with just 0.09 s to spare. The 125d fails to fully close the launch gap.
Both rivals are electronically governed, but not at the same level: the 430i Convertible is capped at 250 (i.e. 155 mph - industry threshold) km/h, the 125d at 240 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 6.61 kg/hp) and transmission (Automatic vs Automatic).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 9.87 seconds. The 0.24 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 6,48 s).
430i Convertible G22 goes from 0 to 100 km/h in 6,24 seconds (calibrated simulation).
