Joined FIAT after graduating, in 1968, and specialised in exhausts, before becoming Lancia technical director in 1975, a job he performed until 1990. He joined Ferrari in 1991, and stayed there until 1999, having a specific role to look after the F1 engine project for a couple of years. After leaving Ferrari, he effectively became an independent engine consultant, but worked very closely with Aprilia's engine projects in motorcycling. From 2011, he was effectively semi-retired, but still worked as an engine consultant, although mainly in the automotive industry, rather than racing, and in particular, renewable energy solutions and electric cars. Claudio, who worked for a while in rallying and had a brief spell as Ferrari team manager, remained in Alessandria until his death in 2025.
