Off the line, the 420i Convertible hits 100 km/h in 8.14 s versus 8.23 s for the XC40 B4. The 0.09 s gap is negligible: both vehicles are neck and neck.
At 200 metres, the 420i Convertible is doing 115 km/h against 115 km/h for the XC40 B4. The gap is 0.11 s. The gap remains stable from the start.
At 400 metres standing start, the 420i Convertible crosses the line in 15.96 s versus 16.10 s. The 0.14 s gap represents roughly 6 m of track - barely a car length.
Past 400 metres, the 420i Convertible continues to build its lead. At 600 metres, it runs at 161 km/h versus 158 km/h. At 1,000 metres, the 420i Convertible finishes in 28.97 s versus 29.39 s, with a 0.42 s lead.
Both rivals are electronically governed, but not at the same level: the XC40 B4 is capped at 180 km/h, the 420i Convertible at 236 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 (8.17 kg/hp vs 9.18 kg/hp) and transmission (Automatic vs Automatic).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 13.40 seconds. The 0.09 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Over 0–100 km/h, XC40 B4 and 420i Convertible G22 are neck and neck (8,14 s vs 8,23 s, no significant gap).
XC40 B4 goes from 0 to 100 km/h in 8,23 seconds (calibrated simulation).
