Styling changes for 1975 brought dual, square headlight lenses flanked by rectangular cornering lights wrapping around the body. A new cross hatched grille appeared. Calais Coupes and Sedans had triangular "coach" windows. Standard equipment was about the same as in 1974, plus front fender lamp monitors; power door locks; high-energy ignition; steel-belted radial tires and catalytic converter. Once again, substantial mid-year price increases were seen. Also, all cars offered at the beginning of the model run were equipped with 500 cubic inch V-8s and electronic fuel injection became optional in March, 1975.
