"In 1930, one of the foremost engine designers and researchers in the early years of the development of the internal combustion engine, Sir Harry Ricardo, developped a Diesel variant of the Rolls Royce V12 Kestrel aero engine. This engine helped the land speed record breaking car 'Flying Spray' (f.k.a. Speed of the Wind) set a new diesel speed record at Bonneville Salt Flats, 159 mph, a record that would stand until 1950."
