Fiat 133 er en Seat 133 produsert og designet av Seat i Spania:
The SEAT 133 was a small rear-engine car designed and sold by SEAT in Spain from 1974 to 1979. The car used the chassis and engine of the by then defunct Fiat/SEAT 850 and featured a new body in the style of the contemporary, somewhat smaller and only indirectly related Fiat 126. The car was first exhibited at the Barcelona Motor Show in May 1974.
The 133 effectively replaced the SEAT 600 which had been produced in considerable numbers with around 800,000 built - almost exclusively for the domestic market - by 1974. Initially the 133 was only sold in Spain and did not enjoy great success, since it suffered from frequent overheating problems. However, it enjoyed success in other parts of the world, like Egypt for example, where the car is still in service.
Reflecting the rear engine lay-out, there was just a small well for parcels behind the back seats, with more room for luggage under the 'bonnet/hood' at the front of the car.
Up to 200,000 SEAT 133s had been produced by 1979 in Spain. A further 15,821 were made in the Fiat/Sevel Plant at Córdoba in Argentina between 1977 and 1982.
The SEAT 133 was exported to Germany from the Autumn/Fall of 1974 here it found some success among rear wheel drive-loyalists in the mid-seventies. It was also sold in Britain from June 1975. These countries had no SEAT dealership network at the time, and the cars were branded as Fiat 133s, to be marketed alongside the Fiats 126 and 127.
The Fiat 133 was a car developed in Spain by SEAT, with which Italian company Fiat had signed an agreement of collaboration in the 1950s. The 133 was a meant to replace the old 600 and 850 models, and to provide a means for SEAT to open new markets and make up for the loss of sales in Spain that would come with the disappearance of the restrictions in car imports during the 1970s. The 133's design premise was that it had to be a cheap car both to develop and build. Thus, the final product inherited most of its components from the Fiat 850. As with the 850, it was a rear-wheel drive, rear-engined car, a layout a that was being replaced by a trend for front-engined, front-wheel drive hatchbacks like the Renault 5 and Fiat's own Fiat 127.
The 133 began production in 1974, and was introduced in April at the Barcelona Autoshow. Around 127,000 units were exported, mostly under the Fiat name, and from 1977 to 1980 the Fiat Argentine subsidiary built them also, under the Fiat name.
The 133 is also popular in the low-budget Finnish motorsport called Jokkis, where over 50 per cent of the drivers drive Fiat 133s.
