1953 Sunbeam Alpine Mk I
context: The Series I used a engine and was styled by the Loewy Studios for the Rootes Group. The car made extensive use of components from other Rootes Group vehicles and was built on a modified floorpan from the Hillman Husky estate car. The running gear came mainly from the Sunbeam Rapier, but with front disc brakes replacing the saloon car's drums. An overdrive unit and wire wheels were optional. The suspension was independent at the front using coil springs and at the rear had a live axle and semi-elliptic springing. The Girling-manufactured brakes used discs at the front and drums at the rear. It had dual downdraft carburetors, a soft top that could be hidden by special integral covers and the first available wind-up side windows offered in a British sports car of that time.
