Originally RAF Boreham, with the facility released from military control, in 1946, the West Essex Car Club developed the 4.76 kilometre perimeter track for motor racing.
[citation needed] Although not on the official Grand Prix calendar, Boreham Circuit hosted competitive races between 1949 and 1952.
[1] In 1955 the Ford Motor Company bought the airfield to use as a test facility for trucks, as well as the base for their Competitions Department where they prepared their cars.
[citation needed] In the late 1970s Boreham Proving Ground was the test site for Ford Heavy Truck Development.
Test drivers were not very happy if they were allocated four days of driving "Korean Road" to gather RLD since they were bumped around in the cab constantly.
