A major restyling marketed the "Gas Crunch" era Cadillacs of 1974. A wide egg crate grille was used. Dual round headlamps were mounted in close together square bezels. Further outboard were double-deck wraparound parking lamps. Shorter vertical grille guards appeared in about the same position as before. Rear fender sides were flatter, without the elliptical bulge. The thin belt line moldings was positioned lower by several inches. The rear end had vertical bumper ends with the taillights built in. Both bumpers, especially the rear, protruded out further from the body. Coupes sported large, wide "coach" windows giving a thick center pillar look. A new curved instrument panel housed a digital clock. Standard equipment included:
