World Speed Record Use
New airspeed records were set after the 1929 and 1931 Schneider Trophy contests, both achieved using the R engine. In the two decades before World War II, the quest to break the land speed record was hotly contested, particularly so in the early 1930s. Aero engines were often used to power wheeled vehicles to ever-higher speeds, chosen because of their high power-to-weight ratios: the Liberty engine, Napier Lion and the Sunbeam Matabele were among the engine types used in the 1920s. The Rolls-Royce R was the latest development in high-powered aero engine design at the time, and was chosen by several makers of land speed record-contending cars; the engine was also chosen for powerboats attempting the water speed record. One car and two boats successfully used the combined power of two R engines.

Famous quotes containing the words world, speed and/or record:
“The world is a comedy to those that think, a tragedy to those who feel.”
—Horace Walpole (1717–1797)
“The correct rate of speed in innovating changes in long-standing social customs has not yet been determined by even the most expert of the experts. Personally I am beginning to think there is more danger in lagging than in speeding up cultural change to keep pace with mechanical change.”
—Mary Barnett Gilson (1877–?)
“Unlike Boswell, whose Journals record a long and unrewarded search for a self, Johnson possessed a formidable one. His life in London—he arrived twenty-five years earlier than Boswell—turned out to be a long defense of the values of Augustan humanism against the pressures of other possibilities. In contrast to Boswell, Johnson possesses an identity not because he has gone in search of one, but because of his allegiance to a set of assumptions that he regards as objectively true.”
—Jeffrey Hart (b. 1930)
