Machine Overview & Description

Ferrari 512 is the name of several race and road cars built by Ferrari. The name might indicate that the displacement of the V12 engine would be roughly 5.0 L. This may not always be the case since Ferrari would sometimes use the rather odd system of designating individual cylinder displacement for their V12 engines. For example, in the cases of the 250 GTO or 365 Daytona, when times 12, will give a total displacement of 3000 and 4380 cc. However, in the specific case of world sports car championship and the FIA /24 hours of Le Mans Sports 25 racing cars, regulations in those days restricted maximum displacement to 5.0 L. The Ferrari 512 displaced 4993 cc (bore 87.0 mm, stroke 70.0 mm) so that the "512" designation should be interpreted as "5.0 L/12 cylinders". Later flat-V12 powered Ferrari road-cars also used this type of designation.

Until 1967, Ferrari raced four litre prototypes (see Ferrari P), but due to high speeds achieved in Le Mans also by the seven litre V8 Ford GT40, the rules were changed for 1968 limiting Group 6 Prototypes to a maximum engine capacity of 3.0 litres, as in Formula 1. Despite having a suitable engine, Ferrari sat out the 1968 season, to return in 1969 with the Ferrari 312P. In that year, Porsche had taken full advantage of a loop hole with the Porsche 917, making the risky investment of building 25 examples of a 5.0 L car to allow homologation into the FIA's Group 5 Sports Car category. Selling a part of his business to Fiat, Enzo Ferrari raised the funds to match that risky investment. Surplus cars were intended to be sold to racing customers, which means that several dozen high powered sports cars were available, and with each requiring two drivers in an endurance race, there was a shortage of experienced pilots.

The motor of the 512S was a total new 60° V12 with 560 PS (412 kW) output. Compared to Porsche's air-cooled flat-12, it needed a maze of cooling pipes and a heavy radiator. Since the chassis was of sturded steel, reinforced with aluminium sheet, weight was 100 kg more than that of the alloy-framed 917. Notwithstanding the weight difference and higher center of gravity, the Ferrari 512S and Porsche 917 were theoretically fairly even matched.

At the beginning of 1970 the Ferrari 512s were hampered by predictable teething problems, including a weak suspension and transmission bothers. But the fact that Porsche had already six months of equally mixed experience with its 917 in 1969 should be decisive for the rest of the season.

Contrary to Porsche, Ferrari did not organise an intramural competition. At Porsche, JWA Gulf, KG Porsche Salzburg and later Martini Racing, received all direct factory support. Thus, at least four cars were real works cars, without putting strain on the factory itself, as personnel and funds were provided by these professional teams. And even the privateers like AAW Shell Racing and David Piper Racing received a much better support than Ferrari's clients. Ferrari did not adopt this modern scheme, but entered cars themselves in the traditional manner, as Spa Ferrari SEFAC. Having only few Formula 1 drivers under contract in the previous years, with the sports car aces driving for Porsche, Ferrari could barely find qualified drivers for its entries. Beside the factory cars, there were the private cars of Scuderia Filipinetti, NART, Écurie Francorchamps, Scuderia Picchio Rosso, Gelo Racing Team and Escuderia Montjuich. Those private cars never received the same support from the factory. They were considered as field fillers, never as candidate for a win.

At the end of the 1970 season, Ferrari had won the 12 hours of Sebring, while Porsche 917 and 908 took all other nine wins of the championship season. The modified 512M had proven to be fast at the end of the season, and Ickx/Giunti also won[2] the Kyalami non-championship Springbok 9 hours race. As the loop hole for the five litre sports cars would become obsolete after 1971, Ferrari decided to abandon factory entries of the 512 in favor of developing a new three litre prototype. In 1971, Penske entered an improved 512M (#1040) in Sunoco livery which was able to challenge the 917, taking pole position several times.

Technical Specifications

Just in time for the 24h of Daytona, Ferrari in January 1970 presented the required number of 25 512S, as 17 complete cars and 8 assembly kits, to the homologation authorities. Of those cars, fitted with the traditional even chassis numbers, ranging from 1002[3] to 1050, 19 were raced in 1970, 5 of them being spyders. Unlike Porsche, which has build over 50 917s in total, Ferrari could not sell off all surplus cars, and chassis 1046 was given to Pininfarina to be turned into a show car, the Ferrari 512 S Modulo.

The only 512 chassis winning major races in 1970 were 1026 (Sebring) and 1010 (Kyalami).

Of the 25 cars manufactured for the 1970 season, but not raced that year, the 1020 was converted at the end of the season as a 512M and sold to NART, which entered it in competition in 1971. The 1024 remained unsold in 1970, was transformed into a 512M and sold one year later to the Scuderia Brescia Corse. The 1036 was used as test car by the racing division of Ferrari. Later it was sold to Solar Productions for Steve McQueen's Le Mans, also known as French Kiss with Death.

The 1040, sold to Chris Cord and Steve Earle, was entered in 1971 by Penske at Daytona, Sebring, Le Mans and Watkins Glen, setting the pole positions at the American tracks. The 1046 had been disassembled for parts, used for the construction of the Pininfarina Ferrari Modulo, and likely remains under that body in Pininfarina's museum. The 1048 was sold as test car to Scuderia Filipinetti but not raced in 1970. The 1050 was sold to Corrado Manfredini (but only as chassis plus body), combined with parts of 1022 and 1032, transformed into a 512M and raced in 1971.

Eventually the factory team used nine cars for international endurance racing. The Scuderia Filipinetti (Switzerland, Herbert Müller) and NART raced two cars each. Écurie Francorchamps (Belgian importer of Ferrari), Escuderia Montjuich (Spain), Gelo Racing Team (Germany) and Picchio Rosso raced one car each. After the 1022, bought by the last team, was destroyed at the 24 Hours of Daytona, they would use the 1032.

During the 1970 race season several other Ferraris 512S were destroyed. That was the case with the 1012 spyder after its crash at practice for the ADAC 1000km Nürburgring. The 1026, having been raced as factory car #7 by Derek Bell and Ronnie Peterson at the 1970 Le Mans 24 hours, was destroyed during the Le Mans film by Derek Bell. The 1032 chassis number was subject of controversy in the 1980s, and even Christies was involved. Indeed on the reconversion of the 1032 into a 512M parts were used to rebuild it on the 1050 chassis. Up from November 1970 there was no longer a 1032. Nevertheless Christies let believe in 1989 that a replica, built by England's Michael Cane, was the rebuilt 1032.
