The Mitsubishi 6B3 engine is a range of all-alloy piston V6 engines developed by Mitsubishi Motors. Currently, only one engine has been developed, a 3.0 L (2,998 cc) V6 first introduced in the North American version of the second generation Mitsubishi Outlander which debuted in October 2006.[1][2]
All engines developed within this family have aluminum cylinder block and head with iron cylinder liners, 4 valves per cylinder and MIVEC variable valve timing. It uses a timing-belt, the last V6 engine that still uses it.
