The 1980 season saw further aerodynamic progress by Cosworth DFV teams, and a heavily updated version of the 312T4, the 312T5 was introduced at the start of the season. The Ferrari was totally outclassed as their wide 312 Boxer engine did not suit the aerodynamic needs. The car was unreliable, slow and was not effective against the competition. The other constructors' cars got better throughout the season whereas the 312T5's development virtually went nowhere – the car became less and less competitive over the season. For the first time since 1973, Ferrari did not win a race for an entire season, and the team finished 10th in the Constructors' Championship.
