1938 Alfa Romeo Tipo 158 Alfetta

1938 Alfa Romeo Tipo 158 Alfetta
The Alfa Romeo 158/159, also known as the Alfetta (Little Alfa in Italian), is one of the most successful racing cars ever produced. The Alfa Romeo 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 Formula One World Championship.
The first version of this successful racing car, the Alfa Romeo 158, was made during 1937/1938. The main responsibility for engineering was given to Gioacchino Colombo.
The car's name refers to its 1.5 litre engine and eight cylinders. The voiturette class was for racing cars with 1.5 litre engines, standing in the same relation to the top 'Grand Prix' formula (usually for 3 litre engines) as the GP2 series does to Formula One today. Alfa's 3 litre racing cars in 1938 and 1939 were the Tipo 308, 312 and 316.
The Alfa Romeo 158 debuted with the works Alfa Corse team at the Coppa Ciano Junior in August 1938 at Livorno, Italy, where Emilio Villoresi took the car's first victory. At that time the 1479 cc engine produced around 200 bhp (150 kW) at 7000 rpm. with the help of a single-stage Roots blower. More success came at the Coppa Acerbo, Coppa Ciano and Tripoli Grand Prix in May 1940. Soon World War II stopped development of the car for six years. After the war the engine was developed further to push out 254 bhp (189 kW) in 1946.
In 1947, the Alfetta became eligible for the newly-created Formula One. The new rules allowed 1500 cc supercharged and 4500 cc naturally aspirated engines. The Alfa Romeo 158 was modified again, this time to produce over 300 bhp (220 kW) and was denoted as Alfa Romeo Tipo 158/47. The car made a tragic debut in the 1948 Swiss Grand Prix where Achille Varzi lost control of his car and was killed. Another loss for the team came in practice for the 1949 Buenos Aires Grand Prix, where Jean-Pierre Wimille was killed in an accident (driving with Simca-Gordini).
The car won every race in which it competed during 1950; it was incredible that a car which had originated in 1938 was so victorious. The Alfa Romeo team included talented drivers such as Giuseppe Farina and Juan Manuel Fangio, the latter of whom later won the World Drivers' Championship five times.
At the end of the 1950 season, a further updated version known as the Alfa Romeo 159 was produced.

The Alfa Romeo 6C name was used on road, race and sports cars made between 1925-1954 by Alfa Romeo. 6C refers to a straight 6 engine. Bodies to these cars were made by coachbuilders such as James Young, Zagato, Touring, Castagna, and Pininfarina. Starting from 1933 there was also a 6C version with a factory Alfa body, built in Portello.
The Alfa Romeo 6C 2300 (2309 cc) was designed by Vittorio Jano as a cheaper alternative to the Alfa Romeo 8C.

Alfa Romeo 8C was a famed sports car of the 1930s. The name referred to the straight 8 cylinder engine. The Vittorio Jano-designed 8C was Alfa's primary sports model from its introduction in 1931 to its retirement in 1939.
The first models were the Alfa Romeo 8C 2300, a reference to the car's 2.3 L (2300 cc) engine. The short wheelbase version of this car won the Targa Florio race in Sicily, but it was the Italian Grand Prix victory at Monza that gave it its nickname, "Monza".
The supercharged dual overhead cam straight-8 engine, also designed by Jano, was later enlarged to 2.6 L. In this guise, the Alfa Romeo 8C could accelerate to 60 mph (97 km/h) in less than 7 seconds and could eventually reach 135 mph (217 km/h).

Although 1925 brought drastic changes of regulations, from 1924-1930 the Alfa Romeo P2 was victorious in 14 Grands Prix and major events including the Targa Florio.

The Alfa Romeo P2 was introduced by Alfa Romeo for the Circuit of Cremona in northern Italy in 1924, where Antonio Ascari won at over 158 km/h (98 mph), and then went on to win the speed trial at 195 km/h (121 mph). The car was the first creation of Alfa's new designer Vittorio Jano who had been recruited from Fiat by Enzo Ferrari when Nicola Romeo scrapped the Alfa Romeo P1 after its poor performance in the 1923 Monza Grand Prix against Fiat. The Alfa Romeo P2 was powered by Alfa's first straight-8 cylinder supercharged engine with 2 carburettors placed after the compressor.

2011 Alfa Romeo TZ3 Stradale

2011 Alfa Romeo TZ3 Stradale





The Alfa Romeo TZ3 Stradale by Zagato is based on the Viper ACR  mechanical chassis with a carbon fibre body. "Bellezza necessaria" is the inspiration of this car which matches for the first time an USA power train and can represent the first American Alfa Romeo.
Following Zagato's gentlemen-driver heritage, TZ3 Corsa has been commissioned by the Alfa Romeo Zagato collector Martin Kapp. The first Alfa Romeo TZ3 Stradale has been delivered to the US Alfa Romeo and Zagato collector (and Saratoga Automobile Museum's board member) Eric King. The TZ3 Stradale n°2 and n°3 will be delivered in Japan and Europe.
Both TZ3 Corsa and TZ3 Stradale boast a typical Kamm-tail (K-tail) layout. This solution became famous in Italy with the "Coda Tronca" bodies which were tested by Zagato in the beginning of the 60s. They reached their apex on the Alfa Romeo TZ and TZ2. Kamm Effect is part of the functional design approach that aims to the aerodynamic efficiency. According to this, the CX can be lowered by keeping compact volumes at the same time. The reduction of the wind resistance is assured with the Kamm Tail design, without any need of a very stretched "drop" shape of the tail.
