Cadillac Fleetwood Models & History 1991

Fleetwood 1991

As in previous years, much of what was updated on deVille models also found its way into the Fleetwood coupe and sedan.

This included the 4.9-liter V-8, rated at 200 horsepower, and 4T60-E four-speed automatic transmission with overdrive, viscous converter clutch, and electronic shift control.

Deviating from the updates listed in the deVille listing, Fleetwood models received Computer Command Ride as standard equipment, the previously optional electrochromic automatic day/night mirror as standard, and cast aluminum lace wheels as an option.

Inside, again deviating from deVille updates, was a new White Sierra Grain Leather color was added to the seven colors available in sedans and six in coupes.

Also new was darker stained American Walnut wood appliqués and the optional Custom Seating Package including driver memory seat and driver/passenger seats power recliners.

Outside, again, different from the deVille refinements, was the bodyside inserts with integral Fleetwood lettering replacing the previously seen script on rear quarter panels.


Cadillac’s limited production, executive class sedan mimicked the updates of the Fleetwood coupe and sedans.

Unique to the sixty special sedan was its new body style designator: 6CG69, Sixty Special plaque on the rear quarter panels, Sixty Special nameplate replacing previously used engine plaque at the rear, and the optional Express-Open Astroroof.

Updates included a new standard front seat armrest that included a cupholder, coinholder and storage for CDs.

The power front floor storage drawer formerly offered was eliminated to accommodate rear climate control outlets.

With the new 4.9-liter V-8 and 4T60-E transmission, the Sixty Special’s final drive ratio was 2.73:1.

Also, the 4.9-liter V-8 featured the improved CS144 Generation II alternator that provided a higher power output. The 140-amp alternator provided increased air flow and could withstand higher temperature operation.

The leather interior of the Sixty Special was styled by famed Italian designer Giugiaro of Milan. The hand-crafted leather was offered in three color choices.

A six-position memory feature was added as standard to the front seats, which had 22 power adjustments.

Also, the Sixty Special’s wiper system was refined to provide a wider clearing pattern with less blade chatter and greater resistance to snow and ice fatigue.

Eleven exterior color selections were available in 1991.
