The Morgan Plus 4 (or +4) is an automobile produced by the Morgan Motor Company. It is a more powerful and, in the case of the earlier cars, slightly longer version of the company’s previous 4/4 model. Plus 4 production ran from 1950 to 1969. It was revived in 1985 and filled the gap between the 4/4 and the Plus 8 until 2000. It was again produced from 2005 until replaced in 2020 by the “all new” Plus Four built on a bonded aluminium platform.
