Oldest Unbeaten F1 Record
Loof participated in one Formula One World Championship Grand Prix, the German Grand Prix held on 2 August 1953. He retired with fuel pump failure after two metres of racing, which remains the record for the shortest Formula One career.
Loof was also a motorcycle racer and designer, and scored numerous successes in pre-war years for Imperia of Bad Godesberg and for BMW. He later became one of the founders of the Veritas company, successful in Formula Two with the Meteor racer in the immediate post-war period. The company also built sports cars, mostly BMW-engined, as well as the Panhard-engined Dyna-Veritas cabriolets.
Loof was the head designer of the Veritas car he drove in this race. The company had already gone bankrupt by this time, and its assets were purchased by BMW. He was hired by BMW in styling and body engineering and worked there until he retired due to illness.
