Off the line, the 220d xDrive Gran Coupe hits 100 km/h in 7.43 s versus 7.44 s for the 420i. The 0.01 s gap is negligible: both vehicles are neck and neck.
At 200 metres, the 220d xDrive Gran Coupe is doing 117 km/h against 117 km/h for the 420i. The gap is 0.01 s. The gap remains stable from the start.
At 400 metres standing start, the 220d xDrive Gran Coupe crosses the line in 15.36 s versus 15.38 s. The 0.02 s gap represents roughly 1 m of track
Past 400 metres, the 220d xDrive Gran Coupe continues to build its lead. At 600 metres, it runs at 163 km/h versus 163 km/h. At 1,000 metres, the 220d xDrive Gran Coupe finishes in 28.23 s versus 28.23 s, with a 0.00 s lead. Both vehicles have similar top speeds (232 vs 238 km/h), preventing any comeback.
Both rivals are electronically governed, but not at the same level: the 220d xDrive Gran Coupe is capped at 234 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 (8.24 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 0.01 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Over 0–100 km/h, 220d xDrive Gran Coupe F44 and 420i F32 are neck and neck (7,43 s vs 7,44 s, no significant gap).
220d xDrive Gran Coupe F44 goes from 0 to 100 km/h in 7,43 seconds (calibrated simulation).
220d xDrive Gran Coupe F44: 190 hp, ratio 8,24 kg/hp. 420i F32: 184 hp, ratio 8,29 kg/hp.
220d xDrive Gran Coupe F44: 232 km/h. 420i F32: 238 km/h.
