Cadillac Calais Models & History  1971


Cadillacs were completely restyled with pairs of individually housed squarish headlamps set wider apart. The V-shaped grille had an egg crate style insert and was protected by massive vertical guards framing a rectangular license plate indentation. The Calais wheelbase stretched to 133 inches. It also featured a wide hood with full-length windsplits, a prominent center crease, and hidden windshield wipers. A Cadillac crest decorated the nose and new indicator lamps appeared atop each front fender. A horizontal beltline molding ran from behind the front wheel housing, almost to the rear, stopping where an elliptical bulge in the body came to a point. The rear wheel openings were again enclosed with fender skirts. Calais signature scripts were on front fenders and the right side of the deck lid. Taillamps were of the same general shape as last year, but were no longer divided by a chrome bar. Long, horizontal backup lamps were set in the bumper, on either side of a deeply recessed license plate housing. Standard Calais equipment included
