Cadillac Seville…the new interpretation of Cadillac

4

The first generation Cadillac Seville was built between 1975 (as a 1976 model) and 1979. These were exquisite automobiles marketed as “International-size luxury.” This radically new design was refined and understated…yet unmistakably Cadillac. Powered by GM’s electronically fuel injected 5.7 litre V8 made it a performance luxury sedan.

It was like nothing else that rolled off the Cadillac assembly lines. This genre Seville was the styling predictor for “The next generation of the luxury car” from Cadillac. The 1978 Cadillac Seville demonstrates its prowess…in the continuing saga of “As the Standard of the World Turns.”

The first generation Cadillac Seville’s crisp, contemporary lines found their way onto the 1977-1984 DeVilles, and the 1977-1992 Fleetwood Broughams. Who would ever have thought this vehicle would be larger than anything coming off the assembly lines today.

The Cadillac Seville was an immediate success and was accepted with mixed emotion. This was the mid-1970s when Americans were driving full-size DeVille and Fleetwood models and the thoughts of something this tiny was ludicrous.

America quickly fell in love with Seville and its formal attire. It had impressive maneuverability not to mention ginormous fuel economy. Unfortunately, its design took General Motors by storm. At one point, everything GM built looked like a Seville including cars like the Pontiac LeMans/Bonneville.

All GM Divisions began creating HORRID clones…which were the pinnacle of embarrassment. GM sullied the Seville’s charisma through repetition…ALL of GM’s cars had the Seville’s basic silhouette especially the rooflines. This sadly became the beginning of the end for the illustrious Cadillac Seville…

The Seville used Cadillac’s Triple Braking System. It was equipped with a dual hydraulic master cylinder, separate hydraulic brake lines, and a vacuum assisted power booster.

This braking system provided independent front and rear system operation. The parking brake had an automatic vacuum release and could be used as a true auxiliary brake system in an emergency since it wouldn’t lock with the engine running and car in gear.
