The Alfa Romeo 155 V6 TI etched its name in racing history with a glorious championship win in the 1993 German Touring Car Championship (DTM) season. The car was based upon the Italian manufacturer's 155GTA - of course, with numerous body and mechanical modifications. The front of the car employed a pipe frame work and was mounted with a force to be reckoned with in the shape of the 420hp, 2.5-liter V6. A center diff utilized a planetary gear system with viscuous coupling as part of the full time 4WD system. Four 155 V6 TI cars appeared in the DTM that year, with the two works team vehicles piloted by N. Larini and A. Nannini proving too much for the rest of the hapless field, taking 13 wins from 22 races. 11 of those belonged to Larini, who duly became that season's Drivers' Champion.
