The Marendaz Special 15/90 was a car made in 1936.
The cars had a 1991 cc overhead inlet side exhaust valve six-cylinder Coventry Climax engine. The engine was modified to accept Marendaz heads. The engine was fitted with three carburettors. Power was driven through a single-plate clutch and a four-speed gearbox. The engine produced 90bhp and it's top speed was 82 mph (132 km/h). 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.
It is not known how many were precisely made.
The cars cost £425 when new.
