Designed in the late 1940’s, the use of a double trailing arm front suspension with divided track rods for steering reflected a design concept that owes its origins to the racing Auto Unions of the 1930s. In combination with a cam and peg steering box, it provided a significant improvement in handling and ride comfort over the pre war use of a rigid beam front axle in combination with semi elliptical front springs used on the 1 ½ and 2 litre cars of the Vintage era.
