The '''4A9x family''' was designed by Mitsubishi to replace the [[Orion]] engine in its small vehicles. Mitsubishi designed it to be lightweight, compact and powerful. All 4A9x engines feature an all-aluminium design with chain driven double overhead camshafts, four valves per cylinder (16 in total) and [[MIVEC]] on the intake camshaft. It is the first Mitsubishi engine to use a high pressure die-cast aluminium block.
