In 1977, on the 75th anniversary of the "birth" of two organizations, American Motors and "Popular Mechanics", Chapin described AMC's "corporate "philosophy of difference", under which we strive to offer the American motoring public a wider choice" and stated that "the most significant change we can look to will be the development of alternate sources of power to replace our dependence on fossil fuels."
