Off the line, the Bmw 220i Convertible hits 100 km/h in 7.69 s versus 7.75 s for the Bmw 420d Convertible. The 0.06 s gap is negligible: both vehicles are neck and neck.
At 200 metres, the Bmw 220i Convertible is doing 115 km/h against 116 km/h for the Bmw 420d Convertible. The gap is 0.06 s. The gap remains stable from the start.
At 400 metres standing start, the Bmw 220i Convertible crosses the line in 15.61 s versus 15.64 s. The 0.03 s gap represents roughly 1 m of track
Past 400 metres, the situation changes. The Bmw 220i Convertible maxes out at 220 km/h while the Bmw 420d Convertible keeps accelerating towards 236 km/h. At 600 metres, the gap has dropped to 0.02 s.
Around 523 metres, both vehicles are level. This is the inversion point: the Bmw 420d Convertible overcomes its launch deficit thanks to a 16 km/h higher top speed.
At 1,000 metres, the Bmw 420d Convertible finishes in 28.69 s versus 28.82 s. The 0.13 s delta shows an extremely tight race.
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 8.37 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 0.06 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Over 0–100 km/h, 420d Convertible G22 and 220i Convertible F22 are neck and neck (7,69 s vs 7,75 s, no significant gap).
420d Convertible G22 goes from 0 to 100 km/h in 7,75 seconds (calibrated simulation).
420d Convertible G22: 190 hp, ratio 9,34 kg/hp. 220i Convertible F22: 184 hp, ratio 8,37 kg/hp.
420d Convertible G22: 236 km/h. 220i Convertible F22: 220 km/h.
