Rudolf Caracciola's record of 432.7 km/h (268 mph) over the flying kilometre on 28 January 1938, still remains the fastest ever officially timed speed on a public road (at time of writing, 2006). It also was the fastest speed ever recorded in Germany until Rico Anthes bettered it with a Top Fuel Dragster on the Hockenheimring drag strip.
