1978 CADILLAC FLEETWOOD

FLEETWOOD BROUGHAM - SERIES 6C

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.

FLEETWOOD LIMOUSINE - SERIES 6D

The twin posh "Flagships of the Cadillac fleet" carried styling alterations similar to the "lesser" Fleetwoods. New electronic leveling control was standard. Six-way power driver's seat controls were now in the door armrest. Standard limos sat eight. The seven-passenger Formal Limousine had a standard divided 45/45 front seat with black leather seating, plus a sliding glass partition. Both models had two additional fold-down seats. Florentine velour upholstery was offered in light gray, black, or dark blue. The Automatic Climate Control System could be operated by driver or passengers. A Dual Accessory Control Panel also let passengers operate the power windows -- a logical decision, to be sure. A padded Elk Grain vinyl roof was standard. Not quite as many Formal limos were built as the standard variety. Chrome landau bars were available by special order. So were a full landau roof or cabriolet roof, both in padded Elk Grain vinyl. The landau option offered closed-in rear quarters and a smaller back window. as well as opera lamps.
