The De Tomaso 505/38 is a Formula One racing car model, designed by Gian Paolo Dallara for Italian car-manufacturer De Tomaso and raced during the 1970 Formula One season by Frank Williams Racing Cars.
The car was uncompetitive on debut, failing to finish or be classified the first four races of the year. Disaster struck at the following Dutch Grand Prix. Driver Piers Courage was killed in an accident that saw his De Tomaso 505 flip and catch fire. The loss deeply upset Williams; the distance the team principal now places between himself and his drivers has been attributed to this event.
