The Alfa Romeo 33 (Type 905 and 907) is a small family car produced by the Italian automaker Alfa Romeo between 1983 and 1995. From a mechanical standpoint it was essentially an evolution of its predecessor, the Alfasud, whose floorpan, chassis and drivetrain were carried over—albeit with modifications to the suspension and braking system. The Nissan-based Alfa Romeo Arna was launched shortly after, offering a similarly sized but lower priced car.
The 33 has a unique place in the Alfa Romeo history, as nearly 1 million of these cars were produced. 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.
