BMW 318d Steptronic: what you need to know

Well-argued answers to the most asked questions about this model, based on Caralogy data and simulations.

Where does the 318d Steptronic rank in its segment?

Among the 83 saloons 2017–2021, the 318d Steptronic ranks 7th of 83 in Combined consumption (4.5 L/100, behind the BMW 420d), 42th of 75 in Tank range (889 km, behind the BMW 420d), 78th of 83 in 0–100 km/h (8.3 s, behind the BMW M4 Competition).

What is the range of the 318d Steptronic?

889 km on a full tank (4.5 L/100 on the combined cycle) - 42th of 75 in autonomie du segment.

How much does the 318d Steptronic cost to run?

Running costs depend on your profile (mileage, charging type, city/highway mix). Use the Caralogy consumption simulator for a personalised estimate.

Why not a BMW 420d instead?

The BMW 420d leads in Combined consumption (4.2 L/100 vs 4.5 L/100). The choice depends on your priorities: check the 318d Steptronic vs BMW 420d duel for a detailed comparison.

How does Caralogy calculate its figures?

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.
