He competed in sports car and road races at home, but made trips to Europe along with a large contingent of his fellow countrymen for a limited programme of miscellaneous events from 1949 through to 1951. He won the national sports car championship in 1951 and also scored his best result on foreign soil, taking sixth in the Gran Premio di Roma at Caracalla driving a Maserati A6G.

Subsequently Schwelm-Cruz returned to competition in his ancient Alfa, and was later seen in a Maserati sports.
