BMW 120i: what you need to know
Well-argued answers to the most asked questions about this model, based on Caralogy data and simulations.
852 km on a full tank (6.1 L/100 on the combined cycle) - 51th of 90 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 216d Gran Coupe leads in Combined consumption (4.1 L/100 vs 6.1 L/100). The choice depends on your priorities: check the 120i vs Bmw 216d Gran Coupe 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.
