Earl was sent to Germany after the Second World War by the British Intelligence Objectives Sub-Committee to study the development of 1930s Grand Prix racing cars, and wrote an influential report about them.[3] This report aided British engine designers by presenting them with secrets of German design, based on Earl's interviews with designers at Mercedes-Benz and Auto Union in April and May 1947, and blueprints he obtained.[4]
