The Marendaz Special 15/80 was a car made in 1936.

The cars had a 1991cc overhead inlet side exhaust valve six-cylinder Coventry Climax engine. The engine was modified to accept Marendaz heads. The engine was fitted with two carburettors. Power was driven through a single-plate clutch and a four-speed gearbox. The engine produced 80bhp and it's top speed is not known. A supercharged model was also available.

The cars had a 115-inch wheelbase with semi-elliptical leaf-springs in the front and cantilever springs in the rear. The car was available as a tourer, four-seater coupe and a drophead coupe. It is unlikely that the coupe was ever made. The cars were fitted with servo drum brakes.

It is not known how many were precisely made.

The cars cost £425 when new.
