Alfa Romeo 90: engines, trims and what to check
The Alfa Romeo 90 is a mid-size Alfa Romeo sedan produced from 1984 to 1987 with rear-wheel drive, sitting between the Alfetta and the larger Alfa 6. We look at the engines, trims and what to check when buying this rare classic.
Alfa Romeo 90 in brief
The Alfa Romeo 90 was created as an update to the Alfetta sedan and as a bridge between the Alfetta and the Alfa 6. It features a four-door body, rear-wheel drive and the classic Alfa Romeo layout with the gearbox at the rear axle (transaxle).
The car stands out with its distinctive, angular shape and interesting engine choices. In 1987, it was replaced by the Alfa Romeo 164, so the model was produced for just three years and is now quite rare.
Trims and differences
The main 90 trims differ in engine size and equipment. Lower trims came with 1.8 or 2.0-litre engines, while the top ones had a 2.5-litre V6. Additionally, there was a diesel version.
Higher-spec trims include the 'Super' and 'Quadrifoglio Oro', which boast better equipment and interior finishes. Exact trim names depend on the market.
Engines and gearboxes
In the used market, you'll find 1.8 and 2.0-litre petrol engines, a 2.5-litre V6 (around 150-160 hp) and a 2.4-litre turbodiesel. Check specific details in the car's documents.
The gearbox is usually a 5-speed manual at the rear axle; some versions may have an automatic. All versions have rear-wheel drive.
What to check when buying a used Alfa Romeo 90
The biggest issue with this model is body corrosion: sills, arches, door bottoms, floors, and the boot. Alfa Romeo cars from that era are quite susceptible to rust, so opt for the best-preserved example you can find.
Check the engine (oil leaks, distribution mechanism, fuel system), gearbox and clutch, suspension, and electrical equipment. Some parts are hard to come by, so consult with an Alfa Romeo specialist before buying.
