Ken Tyrrell, owner of Tyrrell Racing needed two new drivers for because Jackie Stewart retired from driving at the end of 1973 and François Cevert was killed at the 1973 season finale in the United States. The team signed Jody Scheckter and Patrick Depailler. In the first three races of 1974, (Argentina, Brazil and South Africa), Tyrrell Racing used the earlier 005 and 006 chassis.
