Subaru became increasingly involved in rallying from 1990 with the Legacy, but it was with the Impreza GT GC8 series (in certain markets known as the Impreza WRX) that the Japanese brand definitively established itself on the rally scene. With the WRX version (2 liters turbo, all-wheel drive) Subaru takes a step forward compared to the Legacy, also benefiting from the withdrawal of Lancia. From its debut in 1993, the Impreza demonstrated its full potential with Ari Vatanen, second in the Rallye des 1000 Lacs. First in Japan, then in the rest of the markets, Subaru introduced the Sti (Subaru Technical International) acronym, which characterizes a whole series of mechanical and aerodynamic developments and improvements, which led to continuous evolutions of the Impreza Group A. The 1994 season It was excellent, with Sainz and McRae and from 1995 onwards it was a whole series of successes, one more important than the other. At the end of the 1996 season, the Group A version of the Impreza gave way to the WRC.
