The drivers of the 512 S factory cars
Compared which Porsche which, from the mid-1960s, strived to align with the top sports car drivers of that era, Ferrari's Mauro Forghieri could not count exclusively on top racers in their quest to win the 1970 International Championship for Makes, as Ferrari had abandoned sports car racing after 1967, save for few entries in 1969. Clay Regazzoni and Jacky Ickx, who had returned from Brabham, were Ferrari's F1 men for 1970, but as endurance racing typically requires two drivers per car, at least six more drivers were needed to enter four cars, to match the four or more Porsche factory-backed entries. Also, Alfa Romeo entered factory prototype cars, and competed for drivers and other personnel.
Starting the season, former Ferrari works driver Pedro Rodríguez had been lost to Porsche's JWA Gulf Racing of John Wyer, and to BRM in F1, while another former works racer, Chris Amon was now involved in F1 with March, just like Mario Andretti.
It was scheduled that Regazzoni, Ickx, Ignazio Giunti, Peter Schetty, Nino Vaccarella and Arturo Merzario should race as many rounds as possible. Only Vaccarella and Schetty were free from F1 obligations. Although fast, they were not such typical all-rounders as Jo Siffert, Brian Redman, Vic Elford, Hans Herrmann and Pedro Rodriguez (of them Siffert raced in F1 for March and Rodriguez raced F1 for BRM, but had not the same heavy testing duties as most other F1 racers), who all could drive, for example, the ultra-fast Spa-Francorchamps in a 917K just as competently as they could drive the twisty, winding Targa Florio course in a 908/03. Ferrari only entered one car in the Targa Florio, driven by Giunti and Vaccarella, whereas Porsche entered 4 cars in the event and won it easily in 1970. Although all of the Ferrari drivers were just as capable, they were not as available as the Porsche drivers. Vaccarella was "the man of the rocky mountains" at the Targa Florio and Schetty was the specialist of hillclimbing racing where Porsche was also a dominant factor until discontinuing factory efforts in the late 1970s. Derek Bell and Jackie Oliver were also unavailable at most endurance races, since they drove F1 for Brabham and BRM. John Surtees, who had quit Ferrari in 1966 after an argument with Eugenio Dragoni, returned for the races in Monza, Spa and at the Nürburgring.
Whilst JWA Gulf, KG Salzburg and Martini Racing could count on stable pairings for the whole season, Ferrari's race director Mauro Forghieri had to change his pairings over and over. Eventually his top racer Mario Andretti could only be present for the three American rounds (Daytona, Sebring and Watkins Glen). In total 12 different drivers were seen in 1970 at the wheel of a factory 512 S. Of them the promising Ignazio Giunti did nine of the ten rounds, being only absent at the BOAC 1000 km. Merzario and Vaccarella made seven entries, Ickx and Schetty six of the ten. Only Vaccarella and Surtees were 35 years old or older. Except for Clay Regazzoni (31), all others were younger than 30 years, with Ickx (25), Peterson (26), Merzario (27) and Bell (28). Peterson was only hired for Le Mans, a serious mistake by Forghieri who should have offered him a full year contract.
Another handicap for Ferrari was its full season commitment to F1 racing, so that the 512 S cars did not receive full technical help at all times. Ickx finished second in the F1 World Championship and won three races, while Regazzoni finished third and won once. Both failed to surpass the points tally of late Jochen Rindt, who had a fatal accident during practice for the 1970 Italian Grand Prix.
Of the 12 works racers on Ferrari 512 S in 1970, nine were still alive in the 2000s. Ignazio Giunti was killed in Buenos Aires in January 1971, driving the brand new Ferrari 312PB. He was leading the 1971 1000 km Buenos Aires race when he collided with the Matra which Jean-Pierre Beltoise was attempting to push back to the pits after running out of fuel. Giunti sustained injuries from which he would not survive. Ronnie Peterson, who started his F1 career in 1971, died from injuries that occurred during the 1978 Italian Grand Prix start. Regazzoni, having been paralyzed from the waist down following an accident at the 1980 United States Grand Prix West, died in a car accident in Italy on 15 December 2006.
