In his debut in F1, Ignazio Giunti, finished fourth with this Ferrari 312 B, at the 1970 Belgian Grand Prix was held at Spa-Francorchamps on 7 June. Race winner Pedro Rodríguez had set a 160 miles an hour lap in a sports car race the week before the Grand Prix. It was also Rodriguez's last victory in Formula One, and BRM's first victory since. This was the second Formula One win ever for a Mexican driver, and the last until the 2020 Sakhir Grand Prix. 

Giunti (1941-1971) was an Italian racing driver. He competed in Formula One as well as in saloon and Sports Car Racing. In 1968, driving for Alfa Romeo, he finished second in the Targa Florio and fourth in the Le Mans 24 Hours race co-driving with Nanni Galli. In 1970, Giunti was signed by Ferrari primarily for their sports-car team. His success earned him a Formula One chance along with Clay Regazzoni, who Ferrari was also trialling at the time. Ferrari signed him for the 1971 season Giunti was killed during his first drive in 1971 whilst racing in the 1000 km Buenos Aires. He was leading the race when his Ferrari 312PB prototype ploughed into the back of the Matra-Simca MS660 of Jean-Pierre Beltoise, who was pushing the car along the track after it had run out of fuel. He died due to the impact and the subsequent fire.
