Fleetwood Cadillac Models & History 1978
The most noticeable difference in appearance between the Brougham and the less costly DeVille sedan lay in Brougham’s distinctively tapered pillar design between front and rear doors. Brougham also stopped itself with four-wheel disc brakes. New this year were the restyled grille and back bumper, plus a weight-saving aluminum hood. Front seats now had seatback pockets. Brushed chrome moldings held new wreath-and-crest ornamentation. The Elk Grain vinyl roof held opera lamps just behind the back doors. Color-coordinated wheel discs repeated the body color in the center. Door-pull handles were new, and the door armrest hold six-way power driver’s seat controls. Brougham interiors held individual reading lamps. The Florentine velour interior was offered in mulberry, light gray, black, light blue, dark green, yellow, or light beige. Leather interiors came in eleven colors.
Standard engine was the 425 cu. in. (7.0-liter) V-8. Oversized steel-belted radials rode match-mounted wheels. New standard equipment included electronic leveling control. Joining the option list were seven new interior colors, rear deck accent stripes, color-keyed bodyside moldings, and chrome accent moldings. Available chromed wire wheels showed the Cadillac insignia on a hexagonal center hub. An electronic-tuning stereo radio with digital readout was available with 8-track tape player. The familiar Astroroof was available too. Brougham d’Elegance added contoured pillow-styled seats trimmed in Florentine velour (in five Antique colors), with velour trim in doors, pull straps, and seatback assist straps. Medium Saddle leather was also available on the 50/50 Dual Comfort front seats. Plush pile carpeting reached up onto the lower doors, and covered front and rear floormats. A “Brougham d’Elegance” insignia was on the glove box door; another outside. Also included: three above-door passenger assist grips, accent stripes, and available turbine-vaned wheel discs.
