Real MPG

Average

Superb to drive. Great handling and steering. Upmarket image. Economical diesel engines culminating in amazingly efficient 320d Efficient Dynamics at 109g/km of CO2.

Firm ride especially noticeable on larger alloys. No spare wheel. Limited rear legroom. Too many coil, injector and high pressure fuel pump problems on petrol engines.
