Sixth generation (1965-1966). For 1966, the car was renamed the Star Chief Executive as the first step towards retiring the name, which by the mid-1960s had become dated. For 1967, Pontiac dropped the Star Chief name for United States sales and renamed the mid-priced model the Executive.
In Canada, Pontiac models used Chevrolet drivelines for greater economy. To ensure that used car buyers in the U.S. were not sold less expensive Canadian models, different series names were used. The Canadian equivalent to the Star Chief was called Laurentian. Nonetheless, Pontiac offered a similarly-named series called the Strato Chief, but this model was the lowest-priced big Canadian Pontiac.
