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 5.8 L/100). The choice depends on your priorities: check the 420i 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.
