The Morgan Plus 4 Plus was a series of cars introduced in 1964. Also known as the +4+, the Plus 4 Plus was offered as a two door coupe, and featured more modern styling than other Morgans. These cars were mechanically based on the Morgan +4, sharing many components including the suspension. The Plus 4 Plus was powered by a 110hp 2138cc inline four engine that was mated to a four speed manual transmission. The Morgan Plus 4 Plus was not a successful model, with only 26 examples built before the end of production.
