The Fiat 131, additionally called "Mirafiori", is a small/medium family car produced by the Italian car manufacturer Fiat from 1974 to 1984. It was exhibited at 1974 Turin Motor Show. The 131 was the replacement for the successful Fiat 124, and available as a two-door and four-door saloon and 5-door estate. The 131 was given the Mirafiori name after the Turin suburb where the cars were produced.
The Fiat 131 employed construction techniques and technologies typical of its day. The body was a steel monocoque. Designed and styled on the typical three-box design, with distinct boxes for the engine compartment, passenger compartment, and boot.
The major mechanical components were also conventional and contemporary, but with some notable advances. The 131 employed a front engine, rear-wheel drive layout, whereby the engine is longitudinally mounted in the front of the car. The gearbox is directly behind the engine, and a tubular propeller shaft, under the transmission "tunnel", transmits the drive to a solid live rear axle.
In 1976, 400 examples of the 131 Rally Abarth were built for homologation purposes. These cars were built in a cooperation between Fiat, Bertone and Abarth. Bertone took part-completed two door standard bodyshells from the production line in Mirafiori, fitted plastic mudguards front and rear, a plastic bonnet and bootlid and modified the metal structure to accept the independent rear suspension. The cars were fully painted an trimmed and then delivered back to the Fiat special plant Rivalta where they received the Abarth mechanicals.
The street version of the car used a 16-valve DOHC derivative of the standard DOHC engine, which equipped with a double Weber downdraught carburettor produced 140 hp. The street cars used the standard gearbox with no synchromesh (Rally type regulations required the use of the same type of synchromesh on the competition cars as on the street versions) and the hopelessly underdimensioned brake system of the small Fiat 127.
