1932 Studebaker Rockne adverts

The Rockne line was only produced in 1932 and 1933. The "65" had a 110 inch (2,800 mm) wheelbase and the "75" a 114 inch (2,900 mm) wheelbase. The "75" was based on the Studebaker Six, while the "65" was based on designs by two engineers under contract for Willys-Overland. When Willys-Overland announced they did not have the money to build the car, the two went on the road to sell it. Studebaker president Erskine was quite impressed, and bought the car and the engineers' services. 

The 1933 Rockne line was reduced to one model, the "10", an update of the "65". The Rockne "65/10" engine would replace all the six-cylinder Studebaker car engines then in production and power Studebaker cars and trucks through 1961.
