Off the line, the 125d hits 100 km/h in 6.48 s versus 7.60 s for the 220i Convertible. The 1.12 s gap is negligible: both vehicles are neck and neck.
At 200 metres, the 125d is doing 130 km/h against 118 km/h for the 220i Convertible. The gap is 0.36 s. The challenger starts to claw back ground.
At 400 metres standing start, the 125d crosses the line in 14.67 s versus 15.54 s. The 0.87 s gap represents roughly 35 m of track - a gap visible to the naked eye.
Past 400 metres, the 125d continues to build its lead. At 600 metres, it runs at 180 km/h versus 163 km/h. At 1,000 metres, the 125d finishes in 26.39 s versus 28.42 s, with a 2.03 s lead. Both vehicles have similar top speeds (240 vs 226 km/h), preventing any comeback.
Both rivals are electronically governed, but not at the same level: the 125d is capped at 240 km/h, the 220i Convertible at 226 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 (6.61 kg/hp vs 8.59 kg/hp) and transmission (Automatic vs Automatic).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 12.27 seconds. The 1.12 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.
