The Ferrari 312T, designed in 1974 under Mauro Forghieri, was a response to the handling issues of the 312B3. It introduced a transverse-mounted gearbox and a new chassis, significantly improving handling. Niki Lauda and Clay Regazzoni led its development, with Lauda winning the 1975 Drivers' Championship and Ferrari securing the Constructors' Championship. The 312T's success continued into early 1976, winning the first three races before being succeeded by the 312T2. The model marked a turning point in Ferrari's F1 performance, racing until the 1976 United States Grand Prix West with five different chassis.
