The first Arno appeared at an end of season Italian Championship round, it apparently didn't handle too well and was difficult to set up. For 1984 Arno built three cars, the A02-384, featuring a honeycomb monocoque with double wishbone suspension, inboard springs and dampers operated by pushrods. This car must have been an improvement as Mancini came tenth in the Italian Championship in his Alfa powered car with a best finish of third.
A new car was built for 1985, the A03-385, but results were disappointing and Arno disappeared during the 1986 season.
