Andretti wants all-Italian Dallara v Ferrari battle in IndyCar
"Having Ferrari would be incredible. Not only as an engine supplier, but also as a chassis builder," said the 1978 F1 world champion and four-time IndyCar champion.
"It is clear that the rules should be changed, but I would like an all-Italian Dallara vs. Ferrari battle. The Cavallino would increase interest in the championship, but there is an obstacle in the rules.
"I suggest Binotto comes and proposes an idea to Roger Penske."
Indeed, Ferrari's involvement in the US series would require a rule change that would open up current engine and chassis supply agreements beyond Honda and Chevrolet for the former, and Dallara for the latter.
