The most marked change was to the front clip, with large rectangular headlamps replacing the earlier twin round units.
[3] Other changes included new trim, wheels, dashboard, mirrors, rectangular headlights, a shorter gear stick, and a refined suspension and brakes.
Trim level was raised compared to the previous 132 and the contemporary 131 Mirafiori, with power steering, electric windows, and door locking.

[5] In March 1984 the Argenta VX arrived, with a supercharged 2.0-liter engine with 135 CV (99 kW) shared with the Lancia Volumex models.
