Motore Lancia 831 A7 - 1600 Turbo
1983 - 1986



Derived from the 4-cylinder engine widely used up to the 1980s in many FIAT and Lancia automobiles, the 831 A7 was the first Lancia engine to be equipped with a turbocharging system (with exhaust gas turbine). In 1983 this engine made its debut in the first series of the Lancia Delta 1600 Turbo.
