Calais Cadillac History 1968

Cadillacwas not about to alter its popular product in any major way, so the same basic styling and engineering continued into the 1968 model year with a number of refinements, but no drastic changes. New grilles were added. They had an insert with a finer mesh and step-down outer section which held the rectangular parking lights just a little higher than before. Rear end styling was very modestly altered. An obvious change was a 165mm longer hood, designed to accommodate recessed windshield wipers, The deck lid also had more of a rake. An enlarged engine offered more cubic inches and torque than any other American V-8 and put out 375 horsepower. Of 20 exterior paint color combinations, 14 were totally new. On the inside, enriched appointments included molded inner door panels and a selection of 147 upholstery combinations, 76 in cloth, 67 in leather and four in vinyl. The Calais four-door pillared sedan was dropped. Standard features for the two remaining styles included:
