The Ferrari 315 S is a sports racing car produced by Ferrari in 1957. The model served as the replacement of the Ferrari 290 MM, which had won the 1956 Mille Miglia and was an effort to dethrone the ever powerful Maserati 450S. [2]
The 315 S employed a front mounted evolution of the 60° Jano V12 engine with two valves per cylinder, six Weber 42 DCN carburettors and four chain-driven overhead camshafts, [3] for a total displacement of 3,783.40 cc (3.8 L). Maximum power output was rated to 360 PS (265 kW; 355 hp) at 7,800 rpm in addition to an increase in power output, the engine was also 9 kg (20 lb) lighter than its previous iteration. This allowed for an estimated top speed of 290 km/h (180 mph). [4] [5]
The Ferrari 315 S drivers took the first two positions at the 1957 Mille Miglia in the hands of Piero Taruffi which ended up being the final race of his career, followed by Wolfgang von Trips. [6] In addition the 315 S finished sixth and seventh at Sebring, third at the Nürburgring and fifth at Le Mans but was then largely replaced by the 335 S. The victory of a Ferrari 335 S in Venezuela and the retirement of the Maseratis granted Ferrari the World Sports Car Championship in 1957. [7] [8]
The change in regulations for the World Sports Car championship to a 3-litre engine limit for 1958 meant the 315 S was replaced by the 250 Testa Rossa.
Only one unit of the 315 S was built from scratch with two converted from a 290 S and 290 MM. They are as follows: [9] [10] 1. Chassis 0656. Originally a 290 S at Buenos Aires in January 1957, upgraded to 315 S for the May Nürburgring race and later repaired by the factory with pontoon fenders when raced in the US. 2. Chassis 0674. Originally a 1956 290 MM renumbered and re-engined as a 315 S for Sebring 1957. In June 1957 re-engined as a 335 S for Hawthorn/Lusso at Le Mans. Converted to pontoon fender bodywork by the factory for the Venezuela GP in 1957, later converted back to correct Scaglietti 335 S configuration. 3. Chassis 0684. Built new as a 315 S, raced twice as such by the factory and only briefly in period in the US without modification before long-term storage and careful restoration.
Piero Taruffi was an Italian racing driver. He raced in Formula One from 1950 to 1956, winning the 1952 Swiss Grand Prix and finishing 3rd in the 1952 World Drivers' Championship. His most notable motorsports victory was the 1957 Mille Miglia, the final running of the cross-country sports car race.
The Ferrari 250 Testa Rossa, or 250 TR, is a racing sports car built by Ferrari from 1957 to 1961. It was introduced at the end of the 1957 racing season in response to rule changes that enforced a maximum engine displacement of 3 litres for the 24 Hours of Le Mans and World Sports Car Championship races. The 250 TR was closely related to earlier Ferrari sports cars, sharing many key components with other 250 models and the 500 TR.

In the early 1950s, Ferrari shifted from using the compact Gioacchino Colombo-designed V12 engine in its smallest class of sports racers to a line of four-cylinder engines designed by Aurelio Lampredi. Inspired by the success of the light and reliable 2.5 L 553 F1 car, the four-cylinder sports racers competed successfully through the late 1950s, culminating with the famed 500 Mondial and 750 Monza.

Vittorio Jano designed a new 60° V12 engine for sports car racing for Ferrari. This new engine, introduced in 1956, combined elements of both Colombo and Lampredi engines with new features. Engine architecture was more of Lampredi school but retained smaller Colombo internal measurements. Jano moved to Ferrari along with his designs for the Lancia D50 in 1955 and went on to design not only a new V12 but also a family of the Dino V6 engines soon after. Some of the technical ideas came from the Jano's Lancia V8 DOHC engine, intended for Formula One. This family of engines replaced Lampredi inline-4s known from Ferrari Monza line and went on to win many international races and titles for Ferrari. The design team comprised Jano as well as Vittorio Bellentani, Alberto Massimino, and Andrea Fraschetti.
The Ferrari 376 S was a sports racing car produced by Ferrari in 1955. It was the first raced Ferrari powered by a new Aurelio Lampredi-designed inline-6 engine, created as a larger alternative to the inline-4 series of engines used in the Ferrari Monza race cars. The intention behind the development of this model was the 1955 Mille Miglia race. It was yet another attempt by Ferrari to match the new Mercedes-Benz 300 SLR in competition. All of the created cars were further converted into a bigger capacity models.
