In 1993, Alfa Corse prepared a radical version of their 155 for the Deutsche Tourenwagen Meisterschaft (DTM) racing series. The effort was quite successful and the model later became one of the winning in DTM.
In the first season Nicola Larini won half of all the races outright, and placed first overall in the series. The company retains his car which is currently on permanent display in their museum.
Throughout the seasons, Alfa Corse updated the 155 TI. In 1996 the car got a 2.5-litre 90° V6 for the newely formed International Touring Car Championship.
