New-generation common rail technology injects precisely-measured doses of fuel into the combustion chamber under a pressure of 2,000 bar, extracting maximum efficiency and enabling even smoother running. The four-cylinder diesel power unit in the 320d needs less than 5 litres of fuel per 100 km, and reaches its maximum engine speed at just 1,750 rpm. Yet it's responsive enough to propel the vehicle from 0 to 100 km/h in just 7.7 seconds.
All BMW diesel engines in the BMW 3 Series are fitted with particle filter as standard and meet EU5 emission requirements.
