Monday 7th June 1937
The day after having finished only second at the Rio Grand Prix, German racing legend, Hans Stuck took two new standing start world records with his Auto Union Grand Prix car. He bettered his own one kilometre record {171.021 km/h (106.268 mph) [21.05 s]} and took over the one mile record {201.098 km/h (124.957 mph) [28.81 s]} set by Caracciola at Gyon 1934. However those records remained unofficial as they were not recognized by AIACR. These were to be Stuck’s last speed record attempts
