In 1970, after several years of underwhelming performances, Ferrari introduced the 312 B model to Formula One. For the first three years, it provided a moderately successful return for the Scuderia, but by 1973 they were being overtaken once again. It was becoming clear that some of the handling issues that plagued the 312 B3 chassis could not be designed out, so it was time for a more significant redesign.
For 1974, Ferrari made big changes. First was signing Niki Lauda away from BRM. The second was the development of the 312 T in preparation for the 1975 Formula One season.
