Off the line, the Bmw 125d hits 100 km/h in 6.48 s versus 7.69 s for the Bmw 220i Convertible. Despite the faster sprint time, the Bmw 220i Convertible is 2 m further along the track at this moment: stronger low-speed acceleration offsets a slower run beyond 100 km/h.
At 200 metres, the Bmw 125d is doing 130 km/h against 115 km/h for the Bmw 220i Convertible. The gap is 0.30 s. The challenger starts to claw back ground.
At 400 metres standing start, the Bmw 125d crosses the line in 14.67 s versus 15.61 s. The 0.93 s gap represents roughly 36 m of track - a gap visible to the naked eye.
Past 400 metres, the Bmw 125d continues to build its lead. At 600 metres, it runs at 180 km/h versus 160 km/h. At 1,000 metres, the Bmw 125d finishes in 26.39 s versus 28.82 s, with a 2.42 s lead.
Both rivals are electronically governed, but not at the same level: the Bmw 125d is capped at 240 km/h, the Bmw 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 8.37 kg/hp) and transmission (Automatic vs Automatic).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 12.89 seconds. The 1.21 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.
