Off the line, the 420i Gran Coupe hits 100 km/h in 7.42 s versus 7.44 s for the 420i. The 0.02 s gap is negligible: both vehicles are neck and neck.
At 200 metres, the 420i is doing 117 km/h against 118 km/h for the 420i Gran Coupe. The gap is 0.04 s. The gap remains stable from the start.
At 400 metres standing start, the 420i crosses the line in 15.38 s versus 15.41 s. The 0.03 s gap represents roughly 1 m of track
Past 400 metres, nothing changes. Same ceiling, same acceleration, same trajectory - both rivals run in formation to the line. The 0.01 s gap at 1,000 metres confirms what the specs already suggested: on track, they’re interchangeable. The real contest happens elsewhere - range, comfort, charging network reliability.
Both rivals are electronically governed, but not at the same level: the 420i is capped at 240 km/h, the 420i Gran Coupe 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 (8.29 kg/hp vs 8.51 kg/hp) and transmission (Automatic vs Manual).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 12.15 seconds. The 0.02 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Over 0–100 km/h, 420i F32 and 420i Gran Coupe G22 are neck and neck (7,42 s vs 7,44 s, no significant gap).
420i F32 goes from 0 to 100 km/h in 7,44 seconds (calibrated simulation).
420i F32: 184 hp, ratio 8,29 kg/hp. 420i Gran Coupe G22: 184 hp, ratio 8,51 kg/hp.
420i F32: 238 km/h. 420i Gran Coupe G22: 236 km/h.
