Also available was the 155 Q4 which had a 2.0litre turbocharged engine and a permanent four-wheel drive powertrain both derived from the Integrale; it was essentially a Lancia Integrale with a different body.
The new model came in "Sport" and "Super" guises. The Sport had a slightly lowered ride height and more aggressive dampers while the Super had the option of wooden trim and electronically controlled dampers and seat controls.
Reception of the new model was generally luke-warm. The 75 had been conceived prior to Fiat's acquisition of the Alfa brand, so as "the last real Alfa" it cast rather a shadow over the 155; the loss of rear-wheel drive was frequently cited as the main cause of the disappointment. Nevertheless, the 155 was entered in Touring Car racing and was successful in every major championship it entered which gradually improved its image.
Belatedly the factory introduced a wider version in 1995 (the "wide-body") which as well as a wider track and revised steering based on racing experience or requirements, also brought in new 16-valve engines for the 1.8 and 2.0litre and also some improvements to cabin materials and build quality. The Q4 was discontinued but the V6 continued.[clarification needed]
There were several Sport Packs available, including a race-inspired body kit (spoiler and side skirts) and black or graphite coloured 16" Speedline wheels. The more genteel could opt for the Super which came with wood inserts in the cabin and silver painted alloy wheels.
The 155 was never produced as a Sportwagon (Alfa's term for an estate / station wagon) but Sbarro made a proposal for such a vehicle in 1994.
Production of the 155 ceased in 1998 when the 155 was replaced by the 156 which was a further development in terms of quality and refinement and finally moved away from the wedge styling — leaving the 155 as the pinnacle of that particular design stream which dated back to 1977 with the dramatic square styling of the Giulietta Nuova.
