both longitudinal and transverse applications. 4K2 series In 2017, Mitsubishi launched a new series of gasoline inline-four engines called the 4K2 series. Originally consisting of three models, 4K20, 4K21 and 4K22, they are available in naturally aspirated as well as turbocharged versions. This new design is based on the 4G6 shortblock, mated to a newly designed DOHC 16-valve head with MIVEC technology. The 4K2 series is also produced by SAME in Shenyang, China. 4K20 Destroked 4G63 shortblock, same as 4G6A but with the new DOHC head. Only available as a turbocharged model (4K20D4T).
