Off the line, the Bmw 220i Convertible hits 100 km/h in 7.60 s versus 7.75 s for the Bmw 420d Convertible. Despite the faster sprint time, the Bmw 420d Convertible is 1 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 420d Convertible is doing 116 km/h against 118 km/h for the Bmw 220i Convertible. The gap is 0.01 s. The challenger starts to claw back ground.
At 400 metres standing start, the Bmw 220i Convertible crosses the line in 15.54 s versus 15.64 s. The 0.10 s gap represents roughly 4 m of track - barely a car length.
Past 400 metres, the Bmw 220i Convertible continues to build its lead. At 600 metres, it runs at 163 km/h versus 161 km/h. At 1,000 metres, the Bmw 220i Convertible finishes in 28.42 s versus 28.69 s, with a 0.27 s lead. Both vehicles have similar top speeds (236 vs 226 km/h), preventing any comeback.
Both rivals are electronically governed, but not at the same level: the Bmw 420d Convertible is capped at 236 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 (9.34 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 12.82 seconds. The 0.15 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Over 0–100 km/h, 220i Convertible F44 wins (7,60 s vs 7,75 s).
420d Convertible G22 goes from 0 to 100 km/h in 7,75 seconds (calibrated simulation).
