It was prepared by the motorsports division of the Fiat Group, at first with a 982 cc engine, obtained by increasing the stroke, coupled to a sportive exhaust, a twin carburetor, and a different camshaft. In 1975, displacement was increased to 1,050 cc, while power climbed from 58 HP to 70 HP at 6600 rpm, for a weight of only 700 kg (1,540 lb).
The two engines were offered in parallel until production of the smaller unit ended in late 1976. The 1975 model was also the first A112 to use a 5-speed manual gearbox. These changes turned the A112 into a nervous machine, much admired by young performance enthusiasts.

Some famous Italian rally drivers, including Attilio Bettega, Fabrizio Tabaton and Gianfranco Cunico, were among the winners of the championship. The increasing popularity of the A112 in historic rallies and hillclimbs led to the reintroduction of a one-make trophy, called Trofeo A112 Abarth, in 2010.
