Members of the famous family of brewers, both Kenelm and his older brother Algernon Lee Guinnes were well known competitors in motor racing events in the years before the First World War and the 1920s. Kenelm, who gained his first experience of motor racing riding as Algernon's mechanic, was also the inventor of the KLG spark plug. In 1922 he set a new World Land Speed Record of 133.75 mph at the famous Brooklands circuit in Surrey.
