The Morgan Plus 4 (or +4) is an automobile produced by the Morgan Motor Company from 1950 to 1969. 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 was revived in 1985 and filled the gap between the 4/4 and the Plus 8 until 2000; it was again revived in 2005.
