The Ferrari 335S was a racing car that Scuderia Ferrari used in sports car races in 1957 .

Technology and racing history

The Ferrari 335S was the third and final racing car in the line of four-cam Ferrari built in 1957. Like the previous 290S and 315S , the 335S was based on the Ferrari 290MM . But the car had the reinforced chassis of the 290S.

The engine was bored out to 4023 cm³ and now had a bore of 77 mm with a 72 mm stroke. With six Weber 44 DCN carburettors and dual ignition, it developed a maximum of 390 hp (287 kW) at a compression ratio of 9.2: 1 at a speed of 7400 rpm. The cylinder head and engine block were made of light metal, the lubrication worked with a dry sump . As with the 290S, the multi-plate clutch was located directly under the starter , which transferred the power of the V12 engine to the rear four-speed gearbox with a limited-slip differential from ZF on the rear De-Dion axle via a cardan shaft running at engine speed . The rear axle had two guide links and a transverse leaf spring that was raised via a connecting piece to reduce the side tilt of the car. The riveted aluminum tank was placed as far forward as possible and provided with deep recesses for the leaf spring on the underside. The tank held 180 liters. Except for the engine, the technical data was the same as that of the 290S and 315S models.

The front axle consisted of double wishbones with coil springs and an anti-roll bar. The steering (from ZF) worked with worm and gear segment. Adjustable hydraulic shock absorbers made by Maurice Houdaille were used on all four wheels. The weak point of the car were the drum brakes, which went back to a development by Aurelio Lampredi and regularly got too hot. It was not until the introduction of the 16-inch spoked wheels that ribbed, cast-iron brake drums developed by Vittorio Jano came into use, which provided a remedy.

The car had a tubular steel frame and a two-seater aluminum body built by Carrozzeria Scaglietti .

The 335S was the most powerful and fastest Ferrari sports car to date. It reached a top speed of 305 km / h, a value that was only surpassed by the 330P3 ten years later. The 330P3, however, was a prototype 150 kg lighter with a 420 hp V12 engine.

In the 1000 km race at the Nürburgring , Peter Collins and Olivier Gendebien drove a 335S to second place in the overall standings. However, the winding Nordschleife was not the right terrain for the 335S, which was built primarily for the Mille Miglia . Peter Collins and Alfonso de Portago drove two 335s there. Louis Klemantaski  - the photographer was a co-driver of Collins like in 1956 - about the 335S: “Its speed was so much faster than anything I had experienced before. The impression of advancing in second and third gear was unforgettable. The pressure in my back when accelerating in the gears, the centrifugal forces that acted on me in the bends soon became very exhausting, not to mention that we were constantly jolted by the chassis. "

Collins set one best time after the other up to 200 kilometers from the finish and was on the verge of breaking the 1955 Stirling Moss course record , which is considered unbeatable . Just before Parma the 335 broke down with an engine failure. In the second 335, de Portago had a momentous accident in the town of Guidizzolo , in which he himself, his passenger and nine spectators were killed.

At the end of the season, the Scuderia celebrated a double victory at the Venezuela Grand Prix with two 335s  - Hill / Collins won ahead of Musso / Hawthorn  - and thus won the 1957 World Sports Car Championship .

Of the four cars built, three are still in their original condition.

In February 2016, a 335S achieved a vehicle auction at the Paris auction house Artcurial at 32,075,200 euros, the highest ever achieved value for an automobile.
