The Alfa Romeo Tipo 33 was a sports racing prototype raced by the Alfa Romeo factory-backed team between 1967 and 1977. These cars took part for Sport Cars World Championship, Nordic Challenge Cup, Interserie and CanAm series. A small number of road going cars were derived from it in 1967, called Alfa Romeo 33 Stradale.

Alfa Romeo started development of the Tipo 33 in the early 1960s, with the first car being built in 1965. It was sent to Autodelta to be completed and for additional changes to be made. It used an Alfa Romeo TZ2 straight-4 engine, but Autodelta produced its 2.0 litre V8 soon after. The 2000 cc (122ci) Tipo 33 mid-engined prototype debuted on 12 March 1967 at the Belgian hillclimbing event at Fléron, with Teodoro Zeccoli winning. The first version was named as “periscope” because it had very characteristic air inlet. It was powered by a 1995 cc (122ci) 90° V8 of 270 hp (201 kW), with a large-diameter tube frame. The original T33 proved unreliable and uncompetitive in the 1967 World Sportscar Championship season, its best result a 5th at the Nürburgring 1000, co-driven by Zeccoli and Roberto Bussinello.

Alfa Romeo Tipo 33/2 Le Mans (1968)

In 1968, Alfa's subsidiary, Autodelta, created an evolution model called 33/2. A road version, dubbed Alfa Romeo 33 Stradale, was also introduced. At the 24 Hours of Daytona, the Porsche 907 with 2.2L engines were dominating the overall race, but Alfa took the 2-litre class win, with Udo Schütz and Nino Vaccarella; after that the car was named as "Daytona".Win was repeated at the Targa Florio, where Nanni Galli and lgnazio Giunti also took second place overall, followed by teammates Lucien Bianchi and Mario Casoni. Galli and Giunti then won the class at the Nürburgring 1000 km, where the 2.5L version finished for the first time, 4th place in the 3.0L class with Schütz and Bianchi. However, in most races, the Alfa drivers were outclassed by their Porsche rivals which used bigger engines. In 1968, the car was used mainly by privateers, winning its class in the 1000km Monza, Targa Florio and Nürburgring races. At the end of season Alfa Romeo had finished third in the 1968 International Championship for Makes.

A total of 28 cars were built during 1968, allowing the 33/2 to be homologated as a Group 4 Sports Car for 1969.

Alfa Romeo 33/3 with Nanni Galli at the Nürburgring in 1971

The Alfa Romeo 33/3 made its debut in 1969 at the 12 Hours of Sebring. The engine was enlarged to 2998 cc (183ci) with 400 hp (298 kW), which put the 33/3 in the same class as the Porsche 908 and the Ferrari 312P. The chassis was now amonocoque. The new car did poorly at Sebring and Alfa did not take part in Le Mans after Lucien Bianchi's death in a practice session. The car took a couple of wins in smaller competitions but overall the 1969 season was not a successful one, and the team was again third in the championship.

In 1970 the bigger 5.0L Porsche 917 and Ferrari 512 dominated, yet Toine Hezemans and Masten Gregory took third overall at Sebring, and Andrea De Adamich and Henri Pescarolo won their class in the 1000km Zeltweg, finishing second overall. Also in 1970, an Alfa T 33/3 was one of the "actors" of Steve McQueen's movie Le Mans, released in 1971.

In 1971 the Alfa Romeo racing effort was finally successful. Rolf Stommelen and Nanni Galli won their class at the 1000km Buenos Aires(followed by De Adamich and Pescarolo), before taking another class win (and second overall) at Sebring. De Adamich and Pescarolo later won outright at the 1000km Brands Hatch, a significant result against the "invincible" 917s. They then took a class win at Monza (where Alfa Romeo took the three podium slots in the prototype class) and another one at Spa. At the Targa Florio, Vaccarella and Hezemans won outright, followed by teammates De Adamich and Gijs Van Lennep. Hezemans and Vaccarella won their class at Zeltweg, and De Adamich and Ronnie Peterson won overall at Watkins Glen. Alfa Romeo finished the season second place in the championship. In 1972 the 5 litre Group 5 Sports Cars were banned and the 3 litre cars of Alfa Romeo, Ferrari and Matra, redesignated as Group 5 Sports Cars, competed together for outright victories.

Alfa Romeo T33/4

A 4 litre version was entered to 1972 and 1974 CanAm series by Otto Zipper, driver was Scooter Patrick. Autodelta was also one of entrants with T33/4 in season 1974. T33/3 version was also used in CanAm series earlier.

The 33 TT 12 (Telaio Tubolare, tubular chassis) appeared in 1973 with the Carlo Chiti-designed 12 cylinder 3.0L flat engine(500 bhp). The 1973 season was more or less development time and in 1974 the car won at Monza 1000 km and finished the season with second place in the championship. It wasn’t until 1975 that, after years of trying, Alfa Romeo won the World Championship for Makes. The season was one of almost total domination with seven wins in eight races.,Winning drivers were: Arturo Merzario, Vittorio Brambilla, Jacques Laffite, Henri Pescarolo, Derek Bell and Jochen Mass. For 1976 Autodelta was concentrating on other things and the car was rarely used in competitions.

The successor of the 33TT12 1976 was the 33SC12, SC referring to SCatolato, a boxed chassis. The 3.0 L flat-12 engine now produced 520 bhp (390 kW). With this car Alfa Romeo won the 1977 World Championship for Sports Cars, the 33SC12s driven by Arturo Merzario, Jean-Pierre Jarier and Vittorio Brambilla having won every race in the series. At the Salzburgring the car reached an average speed of 203.82 km/h (126.6 mph); in that same race Arturo Merzario also tested a 2134 cc turbocharged SC12 producing 640 bhp finishing second with that car. The SC12 Turbo was Alfa's first twin turbocharged V12-engine and it was introduced around same time as Renault's Formula One turbo engine. In the Alfa Romeo engine each bank was fed with its own turbocharger; that feature was adopted by many racecar makers in the following years.

The flat-12 engine was later used on Brabham-Alfa BT45, BT46 and Alfa Romeo 177 F1 cars.

The Alfa Romeo 33 is a small family car produced by the Italian automaker Alfa Romeo between 1983 and 1995. It was essentially an evolution of its predecessor, the Alfasud, which was based on the same floorplan, chassis and mechanicals albeit with some minor modifications. The Nissan based Alfa Romeo Arna was launched shortly after, offering a similar size car but at a lower cost.

The 33 has a unique place in Alfa Romeo history - nearly 1 million of these cars were produced internationally. During its 11 year lifespan the 33 saw a light facelift in 1986 and a significant restyle in 1989. The 33 was discontinued in 1994 and replaced by the Alfa Romeo 145 and 146, which used the same boxer engines but built around an entirely new platform based on the Fiat Tipo.

Launch model (1983-1986)

Initially known as the Alfa 33, the 5-door hatchback was launched in 1983 and a station wagon version (initially badged Giardinetta, later badged SportWagon) was introduced the following year at the same time as a four-wheel drive version of the hatchback. The hatchback was styled by Ermanno Cressoni at the Centro Stile Alfa Romeo, while the station wagon was designed by Pininfarina. Unlike the Alfasud, a 3-door was never launched.

The 33 became renowned for its nimble handling and powerful boxer engines, but also became equally well known for its unreliable electronics and tendencies to rust (a frequent complaint on Italian cars in general at the time). Another issue was its braking and increased unsprung weight — the Alfasud's inboard front disc brakes (mounted on the gearbox) had been moved to the more common outboard discs (mounted on the wheel hubs). The rear discs of the Sud's four-wheel disc arrangement had also been replaced with drums.

The car featured numerous innovations for the company, including an instrument binnacle that moved up and down with the adjustable steering wheel, and a plastic bonnet. The UK launch promoted the sleek design,and the Daily Mail noted its low drag coefficient of 0.36, and very impressive in 1983 with only bigger cars such as the Ford Sierra and Audi 100 able to better it.

A mild facelift in autumn 1986 resulted in a revised range when the 1.7 litre engine was introduced and a new interior which simplified the dashboard, and lost the innovative moveable instrument binnacle. Exterior alterations were limited to indicator lens colour changes and minor amendments to grill and bumpers. A 1.8 litre diesel engine was also introduced in some markets.

Second series (1990-1995)

Alfa Romeo 33 (Series II) 1.7

The 33 was given a more extensive facelift in the end of 1989, the Series II or 'Nuova' 33, which went on sale in January 1990. This featured a revised interior, the introduction of fuel injection, the 1.7 litre engine upgraded to include a 137 PS (101 kW; 135 hp) 16 valve version, and a heavily restyled front and rear ends, in line with the new Alfa "family look" established by the flagship 164. Also new four wheel drive version was introduced called the Permanent 4, which was renamed to Q4 starting from 1992. Late production 33s also do not suffer from the rust problems of their ancestors, as their frames are galvanized in the manner Alfa Romeo introduced with the 164.

Z33 Free Time prototype

Zagato made a tall-bodied three-door prototype, a Compact MPV anticipating the Renault Scénic by over a decade. Called the "Z33 Free Time" this was shown at the 1984 Geneva Motor Show, but the project remained a single prototype. The "Free Time" was no longer than the regular "33" at just under 4 metres (157 in) and retained most of its driving characteristics, but with greatly increased interior space. The tiny six-seater was based on the chassis of the 33 but was visually more related to the Giulietta.
