The Morgan 4/4 has been in nearly continuous production since 1936. All the cars are built in the Morgan tradition of a steel ladder chassis, coach built body and sliding pillar front suspension with live rear axle. Like the +4s, all early cars are flat radiator cars with separately mounted headlights. Again, Morgan were forced to change when the lamps became obselete and from 1955, all Morgans adopted the shape that is familiar to this day.

Morgan 4/4s have always been available as 2 and 4 seaters with a coupe option being available with the Series 1 cars.
