The four-cylinder diesel engines in the BMW 320d.

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 BMW 320d needs just 5.3 liters 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 7.6 seconds.
