The Ferrari 365 GTB / 4 Competizione is a competition vehicle of the Italian car manufacturer Ferrari , that of the road sports cars 365 GTB / 4 was derived, the so-called Ferrari Daytona. In three series with different details, a total of 15 vehicles were built from 1971 to 1973 following two prototypes, which were used in sports car and long-distance races until the early 1980s . None of the cars were factory-used by Scuderia Ferrari ; racing was organized exclusively by private customers.

History of origin

Although the 365 GTB / 4 was not initially intended for use in motorsport, Ferrari developed a competitive version of the coupé from 1969 onwards at the customer's request. The impetus for this was provided by Ferrari's USA importer Luigi Chinetti , who had run the North American Racing Team (NART) since 1957 . At the beginning of 1969, Chinetti ordered a 365 GTB / 4 with a specially made aluminum body, which was given the chassis number 12547. Following it and a second prototype, five "Competizione" models of the 365 GTB / 4 were created annually in 1971 (series 1), 1972 (series 2) and 1973 (series 3). The three series differ from one another in technical details. In contrast to the street versions, all 15 Competizione models were not produced by Carrozzeria Scaglietti , but in Ferrari's own service department, Assistenza Clienti . Without exception, the cars were sold to private customers who then organized the races themselves. There was no use of the Competizione by the Scuderia Ferrari works team.

The individual series

Prototypes

The first competition vehicle based on the GTB / 4 was Luigi Chinetti's custom-made product with an aluminum body (chassis number 12547) from 1969. In the following year, Ferrari converted a standard GTB / 4 with a steel body (12467) according to competition criteria. The car is considered to be the forerunner of the regular Competizione models.

1971: Series 1

Ferrari 365 GTB / 4 Competizione Serie 1

The first series of Competizione models was created in 1971. It included the vehicles with the chassis numbers 14407, 14429, 14437, 14885 and 14889.

The bodies of all Series 1 vehicles were made entirely of sheet aluminum, and attachments including the bonnet and rear window were made of plastic. The first three vehicles in this series (chassis numbers 14407, 14429, 14437) also had plexiglass side windows. As a result and through further savings, the weight of the ready-to-drive car was reduced by more than 200 kg to around 1230 kg. In terms of style, the racing versions basically corresponded to the series Berlinettas. However, changes concerned the design of the front section: Without the bumper, the double headlights were covered by angled plastic glasses, which were supposed to enable maximum light output. In addition, the wheel arches were slightly flared and there were air baffles on the front fenders. The Competizione models took over the Tipo 251 twelve-cylinder from the production GTB / 4. The engine was only slightly revised for this series. One of the measures was an increase in compression to 9.3 : 1. The engine output increased to around 360 HP (265 kW) at 7700 revolutions per minute.

1972: Series 2

1972 Ferrari built five copies of a further developed Competizione. The series includes the vehicles with chassis numbers 15225, 15373, 15667, 15681 and 15685.

In contrast to the Series 1 models, the Series 2 cars had a body made of sheet steel; only the doors and the hoods were still made of plastic. The weight of the car increased to 1380 kg. The vehicles were equipped with 9-inch rims at the front and 11-inch rims at the rear. Therefore, the wheel arches were exhibited much wider than on the Series 1 models. Otherwise there were no significant external changes. The compression of the engine was increased again, it was now 10.1 : 1. The power increased to 402 hp (296 kW) at 8300 revolutions per minute. The Series 2 models reached a top speed of more than 290 km / h.

1973: Series 3

The five Series 3 vehicles built in 1973 had the chassis numbers 16343, 16363, 16367, 16407 and 16425.

Externally, the cars largely corresponded to the Series 2 models; they too had a steel body with plastic hoods. The weight was unchanged at 1380 kg. The engine has been significantly redesigned; he was now much more powerful. The compression fell to 9.9 : 1. Due to modified pistons with chrome-plated piston rings, forged connecting rods and modified camshafts, the engine output rose to 450 hp (331 kW) at 8300 revolutions per minute. The top speed was above 290 km / h.

Customers

Most of the Competizione models have been delivered to Ferrari's importers in North America, France , Switzerland and the UK . They took over a total of eleven of the 15 vehicles as first-time customers and used the cars in their own racing teams in endurance races before selling them to independent customers.

NART

Most of the Competizione models went to Luigi Chinetti's North American NART team, to whom the development of the model was indirectly based. NART took over both prototypes and then one model each of the first (14489) and second series (15685) as well as three copies of the third series (16343, 16367 and 16407).

NART used the cars from 1970 to 1975 in selected US and French endurance races. The team achieved the best result with a Competizione at the 1973 24-hour race in Daytona , which Luigi Chinetti jr. , Bob Grossman and Wilbur Shaw in fifth place overall.

Charles Pozzi

Charles Pozzi , the French Ferrari importer, bought one car from each series (14407, 15667 and 16363). Pozzi only used the cars in French races. The Competizione models he reported achieved the greatest successes in the series. They were class winners at the 24-hour races of Le Mans in 1972 and 1973 and also achieved overall victory in the 1972 Tour de France for automobiles .

Filipinetti

Georges Filipinetti , the Swiss Ferrari importer, bought a series 1 (14437) and series 2 (15225) vehicle. He used the cars in 1971 and 1972 through his Geneva- based Scuderia Filipinetti . After Filipinetti's death in the spring of 1973, his team's motorsport program ended before a third series Competizione could be delivered.

Maranello Concessionaires

Maranello Concessionaires , the British Ferrari importer led by Ronnie Hoare , only took over one Competizione. The team bought a second series car (15681) and took it to the start with three British drivers Peter Westbury , John Hine and Mark Konig in the 1972 Le Mans 24 Hours . The car broke down after an engine failure. Hoare then sold the car to a British customer who reported it again at Le Mans the following year . Here, too, the Ferrari failed for technical reasons.

Écurie Francorchamps

The Belgian racing driver Jacques Swaters , owner of the Écurie Francorchamps , took over a vehicle from the second (15373) and third series (16425). In 1972 and 1973 the team competed with Teddy Pilette and other drivers in the Le Mans 24-hour races and finished eighth and twentieth, respectively.

Other users

Filipinetti, NART and Pozzi usually sold the cars they registered after the first outings to private customers, who for their part often - but not consistently - registered the cars for competitions. Some vehicles came into familiar hands, at least for a time. The former Filipinetti car with chassis number 14437, for example, was registered in 1977 for the actor and amateur racing driver Paul Newman for the Daytona 24-hour race . Newman and his co-pilots Milt Minter and Elliot Forbes-Robinson finished fifth overall. The actor Robert "Bobby" Carradine took over a former NART car (chassis number 16407) in 1977 and took it to the start three times in endurance races with Modena Sports Cars and Dan Ward Racing .

Racing history

overview

Luigi Chinetti reported the first prototype (12547) for NART for the 1969 Le Mans 24-hour race . He personally picked up the car in Maranello in June 1969 immediately before it was used for the first time, covered the 1200 km non-stop drive to Le Mans and then sent the car straight to a training race without any further changes, maintenance, repairs or conversions After a few laps, the light barrier measurement confirmed a speed of over 305 km / h. The car did not finish the race because it was involved in an accident with another NART Ferrari. Both vehicles retired.

From 1971 to 1975 the 365 GBT / 4 Competizione were then regularly registered for endurance races in the USA and France, and occasionally they appeared in other countries. They were often used in the 24-hour races of Le Mans and Daytona as well as the 12-hour races of Sebring and the 6-hour races of Watkins Glen . From 1975 onwards, the Competizione's racing activities decreased; private drivers reported their cars sporadically until 1981. A recent moderate success scored the US Team Modena Sports Cars in the 24 Hours of Daytona in 1979 , the John Morton and Tony Adamowicz in a six-year-old, originally used by NART model third series (16407) finished second overall and as class winner.

In the years that followed, some 365 GTB / 4 Competizione competed in hill climbs and similar events. In the meantime, some vehicles are registered for events in historic motorsport.

Classification

At the races in Le Mans and Daytona, the 365 GTB / 4 Competizione were initially not yet homologated for the Gran Tourismo class, as the minimum production of 500 vehicles required for GT approval was only reached in mid-1971. Until 1971, the 365 GTB / 4 Competizione started instead in the "Sports car up to 5 liter displacement" class, in which they competed with pure competition vehicles such as the Porsche 917 or the Ford GT40 . The first grouping into the GT class took place in 1972. With this new design, the 365 GTB / 4 was also able to win class. Claude Ballot-Léna and Jean-Claude Andruet with Charles Pozzi's Series 2 Competizione (15667) achieved their first victory in the GT class (with 5th place in the overall standings) at the 24 Hours of Le Mans in 1972 . In the following year Ballot-Léna and Vic Elford repeated this success with Pozzi's third-series model 16363.

Private conversions

In addition to the seventeen official Competizione, there were a few more 365 GTB / 4s in racing, which were, however, privately converted into racing vehicles:

• Chassis nos .: 13367 and 13855: 13855 was converted in 1972, 13367 two years later by Sport Auto in Modena for Luigi Chinetti.
• Chassis no .: 14065: Converted by Holman Moody and Traco Engineering for Kirk White and Roger Penske .
• Chassis no .: 14107: Delivered by Luigi Chinetti as a standard 365 GTB / 4 to Harley Cluxton from Arizona . The car was later converted by various tuners, including Traco.
• Chassis no .: 14141: converted by Traco in 1972 for Luigi Chinetti. The car registered by NART achieved second overall place in the 1973 Daytona 24-hour race with drivers Milt Minter and François Migault , ahead of the regular 365 GTB / 4 Competizione.
• Chassis number: 15965: Registered by NART for the Le Mans 24-hour race in 1975 . This car differs from all other 365 GTB / 4s by its Targa body drawn by Giovanni Michelotti .
• Chassis no .: 16717: rebuilt in 1975 by Ecurie Francorchamps and used in the Le Mans 24-hour race; Finish in twelfth place.

Assessments

Luigi Chinetti Junior, who competed in both Le Mans and Daytona with the prototype 12467 and the production model 14489, believed that the 365 GTB / 4 Competizione was a better car than its successor, the 365 GT / 4 BB Competizione and also the 288 GTO . The car was very heavy and stressed the brakes a lot, but had above-average reliability. The 365 GTB / 4 Competizione had not been further developed by Ferrari to the extent that it was necessary.
