THIS CAR
Starting with the 166 MM Berlinetta of 1950, Ferrari offered competition specification GT cars to customers who demanded automobiles that were equally at home on road or track.

With the introduction of the 250 series in 1953, Ferrari’s series of purpose-built GT cars continued to evolve. The 250 Mille Miglia was followed by several versions of the 250 GT Tour de France. In 1960, Ferrari introduced the 250 GT SWB Comp/60, followed the next year by the Comp/61. In 1962, Ferrari unveiled the 250 GTO, which pushed the envelope of GT car design and remained at the top of its class through 1964.

After the FIA refused to homologate the mid-engine 250 LM for the 1965 season, Ferrari decided to build three special competition cars based on the 275 GTB. These cars featured chassis lightened in every conceivable way, equipped with bodies made of the thinnest possible aluminum and 250 LM-specification engines. The most famous of these cars was initially campaigned by Scuderia Ferrari and then by Ecurie Francorchamps at Le Mans, where it placed 1st in Class and 3rd Overall.

Building on the success of these three 1965 cars, Ferrari produced a limited series of 12 similar cars for the 1966 season. The result was the 275 GTB/C – the “C” standing for competizione.

In an essay on the 275 series, noted motor racing historian Doug Nye describes the many unique attributes that distinguish these very special competition berlinettas:

“Here Ferrari tailor-made a circuit-racing gran turismo, which was effectively engineered from the tyres up, rather than a basic production car converted for occasional competition use. The 275 GTB/C is a very different animal indeed beneath its look-alike external skin, and the differences really begin with that external skin itself.

“Where production 275 GTBs were available with either standard-weight steel or lighter-weight aluminum bodywork, the GTB/C’s aluminum skin was of even thinner gauge than standard, to save many more kilogrammes in weight. Apart from the toughed-glass windscreen, the GTB/C’s windows and rear screen were in lightweight Perspex instead of glass, and the wheel-arches were slightly flared to accommodate the latest in (usually) Dunlop Racing tyres.

“The cabin interior was extremely sparsely furnished and equipped, the rear trunk was occupied by enormous long-range fuel tankage – with internal filler cap – and brakes and suspension were carefully tailored and set up for serious competition use in long-duration events. Borrani aluminum-rimmed lightweight wire-spoked wheels [outside-laced front] with knock-off centre-lock fixing were preferred instead of the road cars’ cast-alloy Campagnolo wheels.

“The 3.3-litre V12 engine in GTB/C form was equipped with high lift camshafts, 250 LM-type valves, competition pistons, a redesigned crankshaft and Weber 40 DFI/3 carburetors. Comprehensive use was made of lightweight magnesium castings in place of standard aluminum to save further weight, and the engine was also set up with dry sump lubrication in place of the standard wet sump road-going system.”

Given their specialized nature, many 275 GTB/Cs were sold to privateers such as the North American Racing Team, Ecurie Francorchamps, Maranello Concessionaires, and Scuderia Filipinetti. Despite their limited production, 275 GTB/Cs were extremely successful in racing, capturing class wins at Monza, Montlhéry, Nassau, and Le Mans.

The history of this 275 GTB/C can be traced to April 6, 1966, when Ferrari sent the bare chassis of 09051 to Scaglietti to receive its lightweight alloy bodywork. Completed that July, this GTB/C was the sixth example built, one of only eight specified in left-hand drive, and originally finished in the distinctive color scheme of Argento Metallizzato (Silver Metallic) with black leather upholstery.

Although the factory’s delivery records indicate that 09051 may have been intended for German Ferrari distributor Auto Becker, the GTB/C was instead sold to Renzo Sinibaldi, an amateur racing driver from Rome.

Sinibaldi’s racing career began in 1958 with Alfa Romeo Giuliettas, which he successfully campaigned in local events through 1962. He went on to race an Abarth-Simca in 1963 and a Lotus in 1964. In May 1966, Sinibaldi and Tullio Sergio Marchesi drove the first 275 GTB/C, chassis 09007, in the Targa Florio, finishing 26th. This experience in the latest Ferrari surely inspired Sinibaldi to purchase his own GTB/C the following month.

The first race Sinibaldi entered with 09051 was the 500 Kilometers of Mugello in July 1966. There, he and co-driver Grana drove the GTB/C to an impressive 1st in Class and 7th Overall finish. After his successful debut, Sinibaldi campaigned 09051 in nine races between July and October 1966, placing 1st in Class seven times and capturing an overall win at the Tolentino-Colle Paterno Hillclimb. These results put Sinibaldi in third place in the final standings for the 1966 Italian GT Championship.

Although 09051 was technically sold to Gino di Russo in October 1966, the Ferrari remained in Sinibaldi’s hands, and he continued to race it throughout the 1967 season and into 1968. During this period, he finished 1st in Class at the Trofeo Città di Orvieto and had good results at Vallelunga and the Trento-Bondone Hillclimb.

In August 1968, 09051 was sold to Alberto Federici. In the ensuing period, he entered the Ferrari in the Trofeo Micangeli-Arezzo, the Catania-Etna Hillclimb, and the Trofeo Città di Orvieto, winning his class in all three events. In May 1969, Federici and co-driver Domenico Lo Coco entered 09051 in Italy’s oldest open-road race – the Targa Florio. Wearing race No. 114, the three-year-old Ferrari made a valiant effort, though it eventually retired after an accident damaged the nose. The 1969 Targa Florio is 09051’s last recorded race entry; it did not qualify for the 1000 Kilometers of Monza in April 1970 and was retired from active use.

In 1971, Federici sold his GTB/C to Vittorio Roveda, an oil trader in Watford, England. That September, Roveda traded 09051 to exotic car dealer Robert de la Rive Box for a 250 GTE. From there, the car was sold, via David Piper, to David Flanagan of Liverpool, England. An avid enthusiast, Mr. Flanagan entered the GTB/C in the 1974 Club Ferrari France Rallye at Pierre Bardinon’s Mas du Clos.

In 1978, Martin and Ian Hilton purchased 09051, adding it to a stable that included a 250 California Spider. In 1993, the Hilton brothers sold 09051 and the car was exported to the US, where it traded hands a few times before being sold to a noted private collector and vintage racer whose stable includes some of the finest sports racing car
