BMW 420i Gran Coupe: what you need to know
Well-argued answers to the most asked questions about this model, based on Caralogy data and simulations.
857 km on a full tank (7.0 L/100 on the combined cycle) — 46th of 73 in autonomie du segment.
Running costs depend on your profile (mileage, charging type, city/highway mix). Use the Caralogy consumption simulator for a personalised estimate.
The Bmw 420d leads in Combined consumption (4.2 L/100 vs 7.0 L/100). The choice depends on your priorities: check the 420i Gran Coupe vs Bmw 420d duel for a detailed comparison.
Caralogy does not reproduce manufacturer figures: we recalculate every number through physics simulation, starting from SCx, mass and the power curve. This is why our figures at 130 km/h differ from WLTP. Full methodology on the dedicated page.
