The Maserati A6-GCS/53 Berlinetta by Pininfarina

After WW2, Maserati introduced a new race car based on the prewar 6CM model, named A6 after Alfieri, one of the Maserati brothers, and its Straight-6 engine layout. In 1947 a 2-seater version with a 2-Liter engine was developed called GCS which stands for Ghisa (the Italian for cast iron, referring to its cylinder block), Corsa & Sport. Later a new version of the GCS was developed to take part in the 1st FIA World Sportscar Championship series going to start in 1953, which was bodied as a Spyder designed by Fantuzzi and Fiandri and coded with its birth date: A6-GCS/53.

The 1953 Mille Miglia was disturbed with heavy rain, so a hardtop coachwork wouldn’t be a bad idea. Pininfarina was asked for a Berlinetta body but there was a problem: Pininfarina had just signed a contract with Ferrari and was assigned as the main coachbuilder of the company, which forbade them to have any official contract with other companies. So Guglielmo Dei, a Maserati dealer in Rome acquired 6 chassis and sent 4 of them to Pininfarina as a private commissioner. The beautiful Berlinetta coachwork was designed by Aldo Brovarone and the 1st example was completed in late 1953.

Chassis 2056

The 1st Maserati A6 GCS Berlinetta, on chassis no.2056, was crashed in 1954 during the Giro di Sicilia race by Count Paolo Gravina di Catania and the co-driver was killed. It was sent back to Maserati to be repaired but got abandoned until 1991 when it was sent to Carrozzeria Campana to be restored, and was sold afterwards to Umberto Panini in 1996.

Chassis 2057

The 2nd Maserati A6 GCS, no.2057, was displayed at the 1954 Turin Motor Show which also won the Concorso Internazionale di Eleganza title in Rome. It featured a 2-piece windshield, a light blue low roof and a dark blue body color. Because of the less interest in hardtop race cars, excessive noise & heat inside and in order to reduce the weight, the car was later rebodied as a Fantuzzi Spyder for the Scuderia Centro-Sud team and the chassis renumbered to 2086. Its original body was purchased by Corrado Cupellini, then by Franco Lombardi and mounted on another no.2070 chassis which was originally a spyder.

Chassis 2059

The 3rd Maserati A6 GCS with chassis no.2059, finished in red with white stripes and displayed at the 1954 Paris Motor Show was purchased by Count Alberto Magi Dilligenti and repainted white. Later it was painted in red, delivered to the U.S, sold to Stan Nowak and later to David Sydorick who displayed it at Pebble Beach in its original and restored condition in 1999 & 2000 respectively. This example is known as the most original Berlinetta.

Chassis 2060

The last one, no.2060 painted red with a blue stripe, was purchased by the Centro-Sud team. The original body was changed with a Spyder and mounted on another chassis no.2089. Later in 1970, the car was purchased by Count Hubertus von Doenhoff who wanted its berlinetta body back. Unable to retrieve the original body, or the one initially belonging to no.2057, he had a new replica built by Church Green Engineering of England in a silver paint job. It was displayed at the 2010 Goodwood Festival of Speed and won the Best of Show title in the Cartier Style et Luxe.

Tecnical specifications

Maserati A6 GCS had a naturally aspirated dry-sump straight-6 engine with DOHC 2Valves/Cyl layout, a bore/stroke of 76.5/72mm, a compression ratio of 8.75/1 and a total displacement of 1986cc. Using double Marelli ignition and being fed by 3 Weber 40DC03 Carburetors, it could produce 170hp of power at 7300rpm and 194Nm of torque at 5600rpm. The power was transmitted through a 4-Speed gearbox to the rear wheels which could propel the car to a top speed of about 235km/h. The car featured a race ladder type chassis with a wheelbase of 2310mm built by Gilco, a tubular frame and an amazingly lightweight construction, since the race CGS/53 weighed 740kg and the berlinetta around 100kg more. Its suspension was Double Wishbones with coil spring in the front, and rigid axle with radius arms and coil springs in the rear. It also used Drum brakes on all 4 wheels.

Rebuilts

Chassis 2070
Chassis 2070 Originally fitted with a Fantuzzi Spyder body, this A6GCS/53 was acquired new by Anna Maria Peduzzi. No contemporary competition history of this chassis is known. It was eventually acquired by Franco Lombardi, who at that time also owned the original Pininfarina Berlinetta body from chassis 2057. It was this body that Count Hubertus von Doenhoff tried to acquire for many years for his chassis 2060. In 1997, Lombardi commissioned Giardanego from Italy to rebuild chassis 2070 with the striking low-roof Pininfarina body from 2057. Finished in the original two-tone blue livery, it was shown at the 2010 Goodwood Festival of Speed where it won Best of Show in the Cartier Style & Luxe concours d’elegance.

Chassis 2089
Chassis 2089 Acquired new by Francesco Giardini in 1955, this A6GCS/53 was fitted with a ‘standard’ barchetta body like most of its sister cars. He raced the car with considerable success, winning his class at the Mille Miglia and Targa Florio in 1955. He eventually crashed the car and decided to rebuilt the car with the Pinin Farina Berlinetta body from chassis 2060, which he had acquired from Scuderia Centro Sud. Following a brief spell in the United States, it was shown for many years in the fabulous Rosso Bianco Museum near Frankfurt. The current owner acquired the Pinin Farina Berlinetta around the turn of the century and brought it to the 2005 Pebble Beach Concours d’Elegance where Pininfarina’s 75th anniversary was celebrated.

Opera d’arte!

The Ferrari Berlinetta Boxer (BB), produced from 1973 to 1984, stands as one of Ferrari’s most radical shifts in design and engineering, thanks to the collaborative work with Pininfarina. The BB was Ferrari’s first mid-engine road car, marking a significant departure from Enzo Ferrari’s long-standing preference for front-engine designs. Its introduction signified a new chapter for Ferrari, aligning more closely with the trends set by other supercar manufacturers at the time.

Origins and Design Inspiration

Designed under the direction of Leonardo Fioravanti, the Ferrari 365 GT4 BB (the first iteration of the BB series) debuted at the 1971 Turin Auto Show, and production began in 1973. One fascinating anecdote about the car is that its “BB” initials reportedly stood for Brigitte Bardot, the famous French actress, which was a codename used during development and remained with the model​.

The BB’s design was sleek and revolutionary. It featured a wedge-shaped, low-profile body, which became a staple of 1970s supercar aesthetics. One of its unique design elements was the bicolored bodywork, with a black lower section that visually slimmed the car while emphasizing its elongated shape. Its pop-up headlights and minimalist, flowing lines were indicative of Pininfarina’s ability to combine functionality with elegance, helping the car stand out from its competitors​.

Mid-Engine Innovation

Before the BB series, Ferrari had always adhered to front-engine layouts for its road cars, famously stating, “Never put the cart before the horse.” However, the mid-engine layout, which Ferrari had already used in its Dino models, became necessary as rivals like Lamborghini began popularizing the mid-engine format in supercars.

The 512 BB (introduced in 1976) featured a 5.0-liter flat-12 engine, mounted in the middle of the car, right behind the driver, delivering 360 horsepower. While this engine was commonly referred to as a “Boxer,” it was technically a 180-degree V12, not a true Boxer engine. In a true Boxer engine, opposing pistons move in opposite directions, but in the 512 BB, they moved simultaneously in the same direction​ This flat configuration allowed for a lower center of gravity, which significantly improved the car’s handling.

Performance and Engineering Marvels

The 512 BB was more than just a stylish car—it was a high-performance machine capable of a top speed of 302 km/h (187 mph) and accelerating from 0 to 100 km/h in just 5.4 seconds. The car’s engineering wasn’t just limited to its engine. It featured independent suspension on all four wheels and a sophisticated five-speed manual transmission mounted below the engine, showcasing Ferrari’s commitment to performance.

Over the years, the BB saw several iterations. The BB 512i, introduced in the early 1980s, swapped the carburetors for Bosch K-Jetronic fuel injection, which lowered emissions and improved fuel efficiency without sacrificing too much power. Although the power dropped slightly to 340 hp, it remained one of the fastest road cars of its era​.

Legacy and Influence

The BB series laid the groundwork for Ferrari’s later mid-engine supercars, such as the Ferrari Testarossa, which succeeded the BB 512i in 1984. It also marked a significant shift for Ferrari, transitioning from the era of front-engine grand tourers to mid-engine supercars.

Today, the Ferrari Berlinetta Boxer remains a prized collector’s item. Its combination of cutting-edge design by Pininfarina, revolutionary mid-engine layout, and Ferrari’s racing heritage makes it one of the most iconic cars in the brand’s history. With only 387 units produced of the original 365 GT4 BB, and slightly more of the later 512 BB and BB 512i models, its rarity further solidifies its place in the pantheon of classic supercars.

The Ferrari BB, both for its groundbreaking design and engineering, represents one of Ferrari’s most influential models. Its innovations in the mid-engine supercar market, coupled with Pininfarina’s masterful styling, continue to captivate enthusiasts and collectors to this day.
