Autodelta was founded by Chiti and a partner, Ludovico Chizzola. He didn't want to move from Udine to Milan when Alfa called for that, and remained at his location. That was the time when the TZ was turned into TZ2. Chizzola seemingly built his own view of what should be and evolved TZ, building it smaller and lighter for better agility. This is presented as the result of his effort.
