Off the line, the 220i Convertible hits 100 km/h in 7.60 s versus 7.75 s for the 420d Convertible. Despite the faster sprint time, the 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 420d Convertible is doing 116 km/h against 118 km/h for the 220i Convertible. The gap is 0.01 s. The challenger starts to claw back ground.
At 400 metres standing start, the 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 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 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 420d Convertible is capped at 236 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 (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).
