アルトゥーロ・メルツァリオ
Willi Kauhsen Racing Team gained fame in 1975 World Sportscar Championship season when it represented Alfa Romeo to become the winner of World Championship for Makes contested by Group 5 Sports Cars (2-seater racing prototypes) of under 3L displacement. Kauhsen made a deal for the team with Autodelta, who competed the previous 1974 season with Alfa Romeo 33TT12 somewhat unsuccessfully against Matra, to act as the on-track contingent for the Alfa Romeo racing division, starting with two Tipo 33TT12 for Arturo Merzario/Jacky Ickx and Henri Pescarolo/Derek Bell for the second round at Mugello on March 3.
