The Mitsubishi 4A9 engine is the newest family range of all-alloy inline four-cylinder engines from Mitsubishi Motors, introduced in the 2004 version of their Mitsubishi Colt supermini, and built by DaimlerChrysler-owned MDC Power in Germany (previously a joint venture). All engines developed within this family have aluminum cylinder block and head, four valves per cylinder, double overhead camshaft layouts, and MIVEC continuous variable valve timing (intake only).
