The Ferrari 312PB (officially known as the 312P, but appended with the 'B' by the media to differentiate it from the '69 312P) marked the end of an era. It was Ferrari's last new car developed specifically for sports prototype racing. In the hands of drivers like Mr. Mario Andretti it was a world-beater helping to cement his reputation. The thing is, that as great a racer as he was, other Scuderia Ferrari drivers were similarly successful with the Group 5 car. Drivers Brian Redman and Arturo Merzario each drove the car and combined to win three of the eleven races of the 1972 championship-winning season, a season that saw Ferrari win every race except the 24 Hours of Le Mans (which they sat out due to reliability questions related to the Formula One-derived twelve cylinder).
