hier een stukkie van t net......
In 1992 Alfa Romeo returned to racing with a version of the 155 Q4, renamed GTA, prepared to Italian Superturismo Championship regulations. This car retained very little of the standard production version, sporting carbon wings, a rear spoiler that could be tilted to different angles, and a 16-valve intercooled turbocharged engine capable of 400 bhp (compared with 186 bhp of the road version).
The four team cars were driven by Nicola Larini, Giorgio Francia, Nannini and Tamburini, and the new GTA won 17 of the 20 races it was entered for, while Nicola Larini won the title. During the following year, this model made way for the successful 155 V6 TI prepared for the German DTM Championship.
