The Spirit of Rett is a streamlined car designed to challenge the wheel-driven land speed record.[1][2] On September 21, 2010 it made two speed runs piloted by Charlie Nearburg at the Bonneville Salt Flats. The first run averaged 417.0 mph (671.1 km/h) with an exit speed of 422.6 mph (680.1 km/h). The return run, made under more difficult track conditions, averaged 411.7 mph (662.6 km/h) with a top speed of 417.65 mph (672.14 km/h). The average speed of approximately 414.4 mph (666.9 km/h) exceeded the 45 year old Summers brothers’ Goldenrod record.[3] The “Spirit of Rett” now has the fastest single engine car record in history.[2][4]
The car was named after Nearburg's son who died in 2005.[5][6]
