Alfa started producing the 90 in 1984. The chassis was inherited from the Alfetta, and was redesigned by Bertone.
The suspension comes from the Alfetta too; we can find a wishbone trailing arms in the front, and De-Dion axle in the rear. The engine range counted five units, a 2 litre and 2.5 litre V6 from the Alfetta, a 1.8 and 2 litre 4 cylindered, and a 2.4 litre VM diesel. The power was redirected to the rear whells with the help of the transaxle system.
In 1986 Alfa made minimal changes on the 90, and named as “Super”. For the “Oro” equipment level 90s were installed with a futuristic instrument panel with green leds and lots of comfortable extras were optional too.
The 90 doesn’t fulfilled the expectations – maybe because it had a very soft suspension, undersized brakes etc. – so Alfa stopped the production in 1987.
