MZR is thebrand name of a generation ofInline-four engines engineered and built by theMazda Motor Corporation from 2001 to the present. MZR stands for "MaZda Responsive". The MZR generation includesgasoline anddiesel powered engines ranging in displacements from 1.3 L to 2.5 L.
All gasoline-powered MZR engines feature an all-aluminum block construction with iron cylinder liners. The dieselMZR-CD engines use a cast-iron block (virtually identical to theMazda F engine) and an aluminum cylinder head.
There are three specific engine families within the MZR which include:
The DISI turbocharged MZRL3-VDT was on theWard's 10 Best Engines list for 3 consecutive years for 2006, 2007 and 2008.
TheFord Motor Company co-developed the engines with Mazda during the period where Ford owned a controlling share in Mazda. Ford retains perpetual rights to build and use the MZR generation of engines. Ford has sold the MZR engine under theirDuratec brand name for global service in its vehicles since 2003.
As of 2011, Mazda discontinued development of the MZR generation of engines and began to replace it with theirSkyActiv generation of engines.
