Alfa Romeo 155: Twin Spark, V6 and Q4 — engines and trims
Alfa Romeo 155 — a mid-size sedan, produced from 1992–1998 as the successor to the Alfa Romeo 75. We look at the engines and trims offered, how Twin Spark, V6 and Q4 differ, and what to check before buying such a classic.
155 in brief
The 155 replaced the rear-wheel-drive model 75 and stood out with its angular, striking appearance. Technically, it was built on the Fiat group's platform, but the driving feel remained sporty.
Today, the 155 is a rare and more of a collector's car. It appeals to those who enjoy the Italian character of the 1990s and its racing history: the 155 successfully competed in the DTM championship.
Trims and drivetrain
Most 155 trims have front-wheel drive. The sportier Q4 trim features all-wheel drive and a turbo engine, while the V6 TI was created to compete in the DTM championship.
Choice depends on your needs: Twin Spark is great for daily driving, V6 for those who enjoy power and sound, and Q4 is rarer but more technically complex.
Engines and gearboxes
Petrol engines include the four-cylinder Twin Spark (1.7, 1.8 and 2.0 l, around 115–150 hp), 2.5 l V6 (around 165 hp) and 2.0 l turbo Q4 (around 190 hp). Diesels are the 1.9 TD and 2.5 TD.
Gearboxes are usually manual. Twin Spark trims are the easiest to find, while V6 and Q4 are less common.
What to check when buying a used 155
The most important thing is the body condition: check for dents, wheel arches, the underside and the bottom of the doors for any rust. Due to their age, many cars have already been repaired or were used carelessly.
Check the timing belt change history on Twin Spark and V6 engines. In the Q4 version, test the four-wheel drive, as its parts are specific and hard to find.
Check the electronics, interior trim, and suspension. Ask for the service history and carefully assess whether the car hasn't been modified for sporty performance.
