Off the line, the 420i hits 100 km/h in 7.44 s versus 7.66 s for the 220d Convertible. At this point, the 420i leads by 0.22 s and sits roughly 14 m ahead.
At 200 metres, the 420i is doing 117 km/h against 120 km/h for the 220d Convertible. The gap is 0.46 s. The gap widens compared to the 0-100.
At 400 metres standing start, the 420i crosses the line in 15.38 s versus 15.71 s. The 0.33 s gap represents roughly 14 m of track - two to three car lengths.
Past 400 metres, the gap narrows. The 220d Convertible maxes out at 225 km/h while the 420i keeps accelerating towards 238 km/h. At 600 metres, the gap is down to 0.23 s from 0.33 s at 400 metres.
At 1,000 metres, the 420i finishes in 28.23 s versus 28.34 s, with just 0.11 s to spare. The 220d Convertible fails to fully close the launch gap.
Both rivals are electronically governed, but not at the same level: the 220d Convertible is capped at 225 km/h, the 420i at 240 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 (8.34 kg/hp vs 8.29 kg/hp) and transmission (Automatic vs Automatic).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 12.15 seconds. The 0.22 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Over 0–100 km/h, 420i F32 wins (7,44 s vs 7,66 s).
220d Convertible F22 goes from 0 to 100 km/h in 7,66 seconds (calibrated simulation).
220d Convertible F22: 190 hp, ratio 8,34 kg/hp. 420i F32: 184 hp, ratio 8,29 kg/hp.
220d Convertible F22: 225 km/h. 420i F32: 238 km/h.
