PSA EW/DW engine

The EW/DW uses many parts from the XU, most notably the crankshaft, but is built with lighter materials. The EW name is used for the petrol engines ("e" for essence) and DW for Diesel engines. All EWs are DOHC multivalve with displacement from 1.7 to 2.2 L (1,749 to 2,231 cc). They are mainly used for large family cars and executive cars, as well as large MPVs, although the 2.0 L is also used for some hot hatch models.
