The DeVille series lineup returned intact from the year previous, but �America’s best-selling luxury car� received several upgrades, including speed sensitive steering and speed sensitive suspension as standard equipment
Speed sensitive steering varied the amount of steering effort required of the driver in proportion to the vehicle’s speed.
The deVille’s power-assisted rack-and-pinion steering’s ratio was 17.6:1 with 2.97 turns required lock-to-lock. Speed sensitive suspension automatically selected from three settings � comfort, normal, and firm � to provide optimal ride and handling characteristics at all operating speeds.
The 4.9-liter V-8 and 4T60-E electronically controlled four-speed automatic transmission with overdrive again was the deVille�s power source.
A new feature for 1993 was the Generation II CS144 alternator that delivered 140 amps of power. The CS144 incorporated a self-cooling design for optimal reliability.
Final drive ratio for the Coupe DeVille and Sedan DeVille was 2.73:1.
Exterior improvements included a revised grille for a �bolder� appearance, new blacked-out quarter window molding on the Sedan deVille/Touring Sedan, and formal cabriolet roof on the Coupe deVille.
Two new exterior colors were offered, Dark Cherry and Bronze, upping the total numbers of clearcoat paint colors available to 14.
Two new interior options were available in 1993, Beechwood leather seat color choice and a trunk convenience net.
The deVille continued to offer a driver’s side airbag, solar control glass all-around, Pass-Key II anti-theft system and Twilight Sentinel headlamp system as standard fare.
Remote keyless entry, traction control, and Astroroof remained on the optional equipment list.
The Touring Sedan (deVille) featured the aforementioned speed sensitive steering and suspension systems as well as traction control as standard items.
Outside, the Touring Sedan was distinguished by a grille-mounted wreath-and-crest emblem, front and rear body-color fascia. body-color door handles and chrome-plated bodyside door moldings with �Touring Sedan” identification. Inside, Beechwood color leather was used, and the leather-trimmed steering wheel included a tilt feature and driver’s side airbag.
The instrument panel and doors were trimmed with American Walnut wood inserts.
