1984 CADILLAC DEVILLE

New front-drive versions of DeVille and Fleetwood were anticipated, but delayed because of quality control questions; so for 1984 the rear-drive coupe and sedan carried on. Bodyside moldings were now color-keyed to the body finish. Taillamp lenses held goldtone Cadillac wing crests. All models now had electronic level control. The standard fuel-injected 249 cu. in. (4.1-liter) V-8 engine fed into a revised exhaust system with monolithic catalytic converter.

Electronic controls were modified to meet stricter emissions standards in high-altitude regions. The diesel V-8 remained on the option list, except in California because of its emissions Model regulations. Standard equipment included

power brakes and steering,
whitewall steel-belted radials,
electronic level control,
automatic climate-control air conditioning,
signal-seeking stereo radio with power antenna,
cornering lights,
light monitors
power windows
six-way power seat,
tinted glass,
a remote-control left outside mirror,
right visor mirror,
automatic parking brake release,
P215/75R15 tires
a stowaway spare.

The front-wheel drive editions appeared during the '84 model year as early 1985s.
