The Alfa Romeo 155 struggled to win over the public in the 1990s. As a result, the brand decided to greenlight the development of a sportier and highly exclusive version. A prototype of a 155 with a race-inspired look but designed for the road was then created. This was the GTA Stradale. It was built on the platform of its Italian cousin, the Lancia Delta Integrale. The engine also came from the Delta, but it was redesigned for Group N homologation. Its design became sportier with flared fenders, white wheels, and a DTM-style rear wing. But the project led by Sergio Limone—the man behind the Lancia 037—was canceled. In fact, Alfa Romeo deemed the production of this model too costly. The 155 GTA Stradale remained a one-off prototype but still made a grand public debut at the 1994 Italian Formula 1 Grand Prix as a medical car.
