Why it matters

The 131 Abarth Rally replaced the 124 Abarth Rally as Fiat's official rally car and the road cars were built to meet the Group 4 minimum. In competition it won three constructors' world titles (1977, 1978, 1980) and the drivers' title with Walter Rohrl in 1980.

History

In 1976 Fiat chose the new 131 saloon as the base for its next rally car. Bertone designed and built the lightweight body of aluminium, fiberglass and resin, while Abarth prepared the 1995 cc twin-cam 16-valve engine.

Fiat assembled 400 cars between 1976 and 1978, the minimum for Group 4. The road version used a Weber double-barrel carburettor and gave 140 horsepower, against 225 to 245 HP for the Kugelfischer-injected racing cars.

Identification guide

How to tell an original from a replica or later conversion.

Fiat describes a two-door 131 Mirafiori shape with resin bonnet and mudguards, aluminium doors, enlarged wheel arches, spoilers and large dynamic air intakes on the left of the bonnet and on the sides. The road car has a five-speed gearbox; the ZF self-locking differential was fitted to the racing version only.
