The Alfa Romeo Tipo 308 or 8C-308 is a Grand Prix racing car made for the 3 litre class in 1938. Only four cars were produced, actually modified from Tipo C with the engine mounted lower into the chassis and a slimmer body. [2] [3] The chassis was derived from the Tipo C and the engine from the 8C 2900. The 308 was engineered by Gioacchino Colombo under the control of Enzo Ferrari who was then in charge of Alfa's racing team, Alfa Corse. The car debuted at the Pau Grand Prix in 1938, where two cars were entered to race, one for Tazio Nuvolari and the other for Luigi Villoresi. [4] Both drivers had to withdraw from competition, however Nuvolari had by then set a lap record. The next race was the Tripoli Grand Prix. The new 312 (3-litre, 12 cylinders) and 316 (3-litre, 16 cylinders) were entered, but they had engine trouble during practice and Clemente Biondetti took the start at the wheel of the 308 held in reserve. He failed to finish, while Hermann Lang, driving a Mercedes-Benz W154, was the winner. In this race, Eugenio Siena, driving a 312, was killed after hitting a wall.
In the 1938 Mille Miglia, Clemente Biondetti and Carlo Pintacuda took the first two places. Biondetti's car used a 300 bhp (220 kW) Tipo 308 engine, while Pintacuda's used a 225 bhp (168 kW) 2900B. [5]
In 1938 and 1939, Raymond Sommer won a couple of hillclimb competitions at La Turbie with 308; [4] Jean-Pierre Wimille won a couple of races in Europe in the 1940s. One of the cars was brought to Argentina where it gathered some success and victories in the hands of Óscar Alfredo Gálvez. The car that Gálvez used in Argentina is now in the Juan Manuel Fangio museum. [6]
One of the cars was sold to the US after World War II and Louis Durant drove it to 6th place in the 1946 Indianapolis 500; the next year it placed 7th with Walt Brown. In 1948, Johnny Mauro drove the car to 8th place; this car is now located in the Indianapolis Motor Speedway Hall of Fame Museum. [7] It is probably the same car that was also used in the 1940 Indianapolis 500, which was Raymond Sommer's ex car. [1]
Overall Alfa Romeo's 3 litre formula cars (Tipo 308, 312 and 316) were not a great success. Instead, the new car for the 1500 cc class, the 158 voiturette, designed in 1937 and first raced at the Coppa Ciano in August 1938, proved much more successful.

Emilio Giuseppe "Nino" Farina was an Italian racing driver, who competed in Formula One from 1950 to 1956. Farina won the Formula One World Drivers' Championship in its inaugural 1950 season with Alfa Romeo, and won five Grands Prix across seven seasons.
Pierre Raymond Sommer was a French racing driver. He raced both before and after WWII with some success, particularly in endurance racing. He won the 24 Hours of Le Mans endurance race in both 1932 and 1933, and although he did not reach the finishing line in any subsequent appearance at the Le Mans, he did lead each event until 1938. Sommer was also competitive at the highest level in Grand Prix motor racing, but did not win a race. He won the French Grand Prix in 1936, but the event that year was run as a sports car race.
Jean-Pierre Wimille was a French racing driver and a member of the French Resistance during World War II. He was a two-time victor of the 24 Hours of Le Mans, winning in 1937 and 1939. He is generally regarded as one of the best French drivers of his era.
The Grand Prix du Comminges was an automobile race held in France.
Clemente Biondetti was an Italian auto racing driver. Born into a working-class family, Biondetti raced motorcycles before turning to automobiles where he had greater success.
The Alfa Romeo 8C was a range of Alfa Romeo road, race and sports cars of the 1930s.
The 1936 Grand Prix season was the third year of the 750 kg Formula. The next iteration of the Mercedes-Benz did not prove successful and the team withdrew during the season to instead prepare for the next one. It therefore fell to the resurgent Auto Union team to dominate the racing. In particular, it was their young, new superstar, Bernd Rosemeyer, who mastered the tricky car and who showed superlative skill in wet conditions. Rosemeyer easily won this season's European Championship by winning three of the four Grands Prix.
The Alfa Romeo P3, P3 monoposto or Tipo B was a classic Grand Prix car designed by Vittorio Jano, one of the Alfa Romeo 8C models. The P3 is considered to be the world's first genuine single-seat Grand Prix racing car and was Alfa Romeo's second monoposto after the Tipo A monoposto (1931). It was based on the earlier successful Alfa Romeo P2. Taking lessons learned from that car, Jano went back to the drawing board to design a car that could last longer race distances.
The 1933 24 Hours of Le Mans was the 11th Grand Prix of Endurance. It took place at the Circuit de la Sarthe on 17 and 18 June 1933. Up against five strong privateer entries from Alfa Romeo, the opposition looked fairly weak, mostly being of 1920s vintage. There was a strong British contingent in the smaller classes. The big drawcard was the presence of top European drivers Louis Chiron and Tazio Nuvolari. The current European champion was paired with one of the previous year's winners, Raymond Sommer
The 1935 Grand Prix season was the second year of the new 750 kg Formula. The success of the previous year encouraged the AIACR to reinitiate the European Championship. It was composed of the seven national Grands Prix and was won by Rudolf Caracciola, driving for the Mercedes-Benz team. The team dominated the season winning five of those Grand Épreuves, as well as four of the other major races of the season. However, in one of the great motor-races in sporting history, Tazio Nuvolari in a Scuderia Ferrari Alfa Romeo beat the combined numbers of the German teams in their home Grand Prix. The season also saw the arrival on the international stage of the bright young talent Bernd Rosemeyer in the Auto Union team.
The Alfa Romeo 158/159, also known as the Alfetta, is a Grand Prix racing car produced by Italian manufacturer Alfa Romeo. It is one of the most successful racing cars ever; the 158 and its derivative, the 159, took 47 wins from 54 Grands Prix entered. It was originally developed for the pre-World War II voiturette formula (1937) and has a 1.5-litre straight-8 supercharged engine. Following World War II, the car was eligible for the new Formula One introduced in 1947. In the hands of drivers such as Nino Farina, Juan Manuel Fangio and Luigi Fagioli, it dominated the first two seasons of the World Championship of Drivers.
The 1931 Grand Prix season was a watershed year, with the advent of the AIACR European Championship. After several years of Grand Prix racing in the doldrums with little technical development, 1931 saw new models come from all three main manufacturers: Bugatti, Maserati and Alfa Romeo.
The 1932 Grand Prix season marked the second year of the AIACR European Championship. It saw the debut of Alfa Romeo's sensational new Tipo B and with it, Tazio Nuvolari won the Championship driving for the Alfa Corse works team. The 40-year old Nuvolari won two of the three rounds and was second in the other. Still running to a Formula Libre rules for the cars, the regulations were revised to set the races to be between five and ten hours. However, all three national committees ran their races to the minimum time-limit.
The 1933 Grand Prix season was an intermediate year, as it would be the last season for the current AIACR regulations before a new weight-formula was introduced in 1934. As such, the European Championship was not held and the manufacturers held back on further developments of their existing models. Alfa Romeo, following an Italian government financial bailout and like Mercedes-Benz the previous year, had shut down its Alfa Corse works team. Scuderia Ferrari, their regular customer team took up the role of racing Alfa Romeos and a number of ex-works drivers moved across to join their ranks. They were not allowed, however, to buy the impressive Tipo B that had been so dominant in the previous season.
The 1934 Grand Prix season saw the advent of the new 750 kg Formula. In an effort to curb the danger of rising speeds, the AIACR imposed this upper weight limit that effectively outlawed the large capacity engines. The incumbent manufacturers Alfa Romeo, Maserati and Bugatti had been preparing their new models with varying success – the best of which was the Alfa Romeo Tipo B. However, it was the state-sponsored arrival of the two German teams, Mercedes-Benz and Auto Union, and their innovative and progressive cars that ignited a new, exciting era of motor racing.
The Alfa Romeo 12C or Tipo C was a 12-cylinder Grand Prix car. The 12C-36 made its debut in Tripoli Grand Prix 1936, and the 12C-37 in Coppa Acerbo 1937. The 12C-36 was a Tipo C fitted with the new V12 instead of the 3.8 litre straight-eight of the 8C-35. The 12C-37 was a new car, with a lower chassis and an engine bored and stroked to 4475 cc, now with roller- instead of plain bearings and two smaller superchargers instead of a single large one. The car suffered poor handling, which could not be cured in time for the 1937 Italian GP, and thus was not successful. This is given as the reason for Vittorio Jano's resignation from Alfa Romeo at the end of 1937. The 12C-36 used the existing six Tipo C chassis. Four examples of the 12C-37 were built, although only two were actually assembled for the 1937 Coppa Acerbo and Italian GP. Early in 1938, the Tipo C chassis were modified into 308s, with the straight-eight engine fitted lower in the chassis and a completely new body. The four 12C-37 chassis were instead assembled into 312 and 316 formula race cars.
The 1930 Grand Prix season continued the malaise that had taken over the sport. Although there was little technical advance more privateer teams were forming, getting some factory support. The AIACR continued to mandate its fuel-regulated Formula Libre rules. Across the Atlantic, the AAA abandoned the AIACR regulations. Their new regulations were derisively called the “Junk Formula” by purists, opening up to their own version of Formula Libre: with modified stock-standard cars of up to 366 cu in (6-litres) with two seats.
The Alfa Romeo Tipo 312, 312 or 12C-312 was a 3-litre formula racing car that was used in the 1938 Grand Prix season; drivers were Raymond Sommer, Giuseppe Farina, Eugenio Siena, Clemente Biondetti, Carlo Pintacuda, Jean-Pierre Wimille, Gianfranco Comotti, Piero Taruffi and Pietro Ghersi.
Alfa Romeo Tipo 316, 316 or 16C-316 Grand prix car was used in Grand Prix seasons 1938 and 1939, when it was driven by Giuseppe Farina and Clemente Biondetti. The Tipo 316 was one of three Alfa Romeo cars designed for the new rules in 1938, which differed mainly by the engine, the other two were the Alfa Romeo Tipo 308 straight-8 and Alfa Romeo Tipo 312 with a V12 engine. The car was based on Alfa Romeo 12C-37. It had roots supercharged 60 degree engine from 2,958 cc (180.5 cu in) capacity 58 mm × 70 mm produced 350 bhp (261 kW) at 7500 rpm. The engine was more powerful than the one in Tipo 308 or 312, but it was still not really competitive against Germans.
The Tunis Grand Prix or Grand Prix de Tunis was a motor race held in the 1920s and 30s in Tunis, the capital of the African colony of the French protectorate of Tunisia.
