Cadillac's Brougham series again consisted of the Brougham sedan and special edition Brougham d'Elegance sedan (option code V4S).

Power was supplied by the revised 5.0-liter V8 with throttle body injection (TBI). The "new" 5.0-liter V-8 was rated at 170 horsepower, and featured roller valve lifters for less friction and cast iron exhaust manifolds con�toured for minimal flow resistance. Available previously only with the Coachbuilder Package, the 185-horsepower 5.7-liter V-8 with TBI was now a stand-alone Brougham engine option. Both en�gines were paired with the 4L60 Hydramatic four-speed automatic transmission with overdrive.

Final drive ratio was 3.08:1 (3.73:1 with Coachbuilder and Armor options).

Formerly optional, but now standard features of the Brougham were rear sail panel reading lamps, passenger seat power recliner and six-way power seat adjuster, and leather-trimmed steering wheel.

New standard features included electronic variable orifice steering system in which steering effort was reduced during low-speed driving and increased during high-speed maneuvers to improve stability, and a new ride package. This package consisted of deflected disc shock absorbers, new body mounts and high-rate front and rear springs.

Outside, the Brougham received clearcoat paint as stan�dard, with two new colors added (12 total): Victorian Red and Dark Antelope. Eleven vinyl top color choices were available.

Also new was the optional central door unlocking system includ�ed with the automatic door lock system.

Brougham's stopping power was provided by the Bosch II anti-lock braking system.

Standard tires were self-sealing P225/75R15 Uniroyals that had a distinctive gold letter treatment.

An available trailer towing package gave the Brougham a towing capacity of 5000 pounds.

The d'Elegance sedan featured a specific trim design with multi-but�ton tufted seats. In addition, the interior package included three overhead assist handles and illuminated driver/passenger vanity mirrors.

The d'Elegance again also featured Twilight Sentinel, power trunk pulldown, and specific exterior/interior ornamenta�tion.
