[PAR] [TLE] Land speed record [SEP] The land speed record (or absolute land speed record) is the highest speed achieved by a person using a vehicle on land.  There is no single body for validation and regulation; in practice the Category C ("Special Vehicles") flying start regulations are used, officiated by regional or national organizations under the auspices of the Fédération Internationale de l'Automobile.  The land speed record (LSR) is standardized as the speed over a course of fixed length, averaged over two runs (commonly called "passes").  Two runs are required in opposite directions within one hour, and a new record mark must exceed the previous one by at least one percent to be validated. [PAR] [TLE] Mercedes-Benz T80 [SEP] The Mercedes-Benz T80 was a six-wheeled vehicle built by Mercedes-Benz, developed and designed by Ferdinand Porsche.  It was intended to break the world land speed record, but never made the attempt, having been over-taken by the outbreak of World War II.
