A completely redesigned larger Rambler lineup appeared. The new cars continued the philosophy in building smaller cars than its larger "Big Three" competitors that also had a high degree of interchangeability in parts to keep tooling costs and production complexity to a minimum. The company, which pioneered "styling continuity", introduced all-new styling for the 1963 model year Ambassadors and claimed that these were "functional changes ... not change just for the sake of change." The Ambassadors featured a longer wheelbase, but were shorter due to reduced front and rear body overhangs, as well as a drop in overall height.
