The Multiplex was a sporty, upper-priced and large car equipped with a four-cylinder engine, and offered as a Touring, a Roadster, and a Raceabout.

A prototype "Sports" car with an 85 inches (2,200 mm) wheelbase, weighing in at just 980 pounds (440 kg) and allegedly capable of a top speed of 126 mph (203 km/h) was also built.

There was a brief try with a sports car in 1954, but only prototypes of the Multiplex-Allied 186 with a Willys F-head six cylinder engine and coachwork copied straightaway from the Cisitalia 202 were actually built.
