Curbside Classic: 1977 Cadillac Seville – European Sizes Run Smaller

(first posted 8/28/2017)     For most of their existence, American automakers, particularly the Big Three and especially GM, operated the big, bold, and brash American way. They built the cars they wanted with little constraint on their creative freedom from outside conditions such as fuel economy, foreign competition, and even economic conditions. When it came to luxury cars, with each successive redesign it was about greater size, greater power, and greater road isolation. This is simply how the industry operated and no one seemed to have any issue with it.

Sure, over the years the Big Three did show a few signs of adaptation to market conditions, such as the introduction of compact cars and lower-priced models from higher-end brands, but luxury cars were among the most steadfast in their ways. Brands like Cadillac did not adapt; they defiantly resisted pressure to change.

By the 1970s, however, it was clear that this old, isolationist way of thinking was not going to fly in a new age of German imperialism. Brands like Mercedes-Benz were gaining an ever-increasing percentage of market share, with a more business-like approach to luxury and manageable size versus the overstuffed, overweight American luxo-barges.

Especially when it came to younger buyers, many of whom were just joining the ranks of luxury car owners, this German way of luxury was becoming increasingly appealing. Without anything remotely comparable, the self-proclaimed “Standard Of The World” was at risk of losing its once concrete footing. At last, even Cadillac was forced to concede to societal pressures and marketplace conditions by branching out into a previously uncharted segment. Enter the 1976 Cadillac Seville.

Introduced in early-1975, the 1976 Seville was the smallest Cadillac since at least the 1910s, and some 26.7 inches shorter, 8 inches narrower, and over 900 pounds lighter than a 1976 Sedan de Ville. Likely by no coincidence, the Seville was externally sized right in line with the short-wheelbase W116 Mercedes S-Class, with length, width, and height all within 1.5 inches. Of course, versus a North American-spec 450 SE, the Seville was still some 500 pounds heavier.

Early plans proposed basing the Seville the European Opel Diplomat or even an Australian Holden model, but these were deemed too expensive. Instead, the Seville’s chassis was heavily derived from the economy X-body platform that underpinned the Chevy Nova, Oldsmobile Omega, Buick Apollo, and several others. Engineers stretched the X-body’s wheelbase from 111 inches to 114.3 for the Seville, resulting in its official name as the “K-body”.

Front and rear suspensions, along with steering linkage were also shared with the X-body as well as the Camaro/Firebird’s F-body. Cadillac engineers did make a number of modifications to the suspension and body mounts, such as the addition of Teflon interliners to the rear leaf springs and hydraulic dampers on the steering column and bumper mounts, decreasing vibration and harshness for a smoother, more Cadillac-like ride. Front and rear anti-roll bars were added, however, for less sway.

Although the Seville gained an exclusive “formal” roofline with near vertical rear window and wide C-pillars. To save costs, part of the X-body’s roof stamping used for the forward portion of the Seville’s roof, necessitating a standard full-vinyl roof to cover up all the seams. In order to accommodate an available “bare” steel roof, all new roof stampings were created exclusively for the Seville in 1977.

Unlike other Cadillacs, the Seville did not feature a Cadillac engine. At the time, Cadillac’s smallest V8 was a gargantuan 7.7 liters, and simply too big for the Seville’s engine bay, resulting in Oldsmobile’s 5.7L 350 Rocket V8 powering the Seville. With electronic fuel injection, the Seville was able to achieve a reasonable for the era 15.4 mpg combined, while also offering higher peak horsepower and lower emissions than the carbureted version of the 350 Rocket found in other cars.

Output of this engine in the Seville was 180 horsepower and 275 lb-ft torque. Not that it probably mattered to most Seville clientele, but it was capable of a zero-to-sixty sprint of 11.5 seconds. This was just three-tenths slower than the lighter Mercedes 450 SE, which for North American spec had the same horsepower but only 220 lb-ft torque from its 4.5L single-overhead cam V8.

Headed under legendary chief GM stylist, Bill Mitchell, the Seville ushered in a new era of styling for Cadillac and GM, setting the tone for GM designs for the next decade. Highlighted by crisp lines, sharp angles, and low beltlines for a trim, square shape, the Seville’s design was clearly European-influenced, and represented a clean break from the bulges and pudginess of contemporary American cars.

While novel at the time of its introduction, the Seville’s design language soon made its way to other GMs, copied again, and again, and again. Within just a few years, everything from the Chevy Celebrity to the Pontiac Bonneville to the Oldsmobile Eighty-Eight to the Buick Regal to the Cadillac Fleetwood would wear this squared-off, formal roof styling to the point where it was nearly impossible to distinguish one GM-branded car from another to the untrained eye.

Inside, Cadillac stylists took far fewer leaps forward in design, providing an interior that would be familiar to the well-seasoned Cadillac buyer of the era. Like other Cadillacs, Sevilles featured a visually similar sweeping dash design, with minimal instrumentation beyond a large horizontal speedometer. Light and climate controls were arranged to the left of the steering column, with radio, defogger controls, cigarette lighter and ashtray to the right.

Despite what might be called a lack of originality, a more understated interior was better suited for the Seville than something more baroque. As expected, lots of fake wood in Cadillac’s preferred “peel-‘n’-stick” variety from the era was present. Velour cloth in eight available color choices was standard with Sierra Grain leather optional in nine color combinations.

As expected, the 1977 Cadillac Seville came very generously equipped for the era, with standard features including four-wheel disc brakes, load-leveling suspension, automatic climate control, power windows and locks, AM/FM stereo with power antenna, 6-way power driver seat, 50/50 split front bench seats, and cornering lights.

Rather defiantly, Cadillac chose to price this heavily re-engineered Chevy Nova higher than any of its other and significantly larger vehicles (sans the Seventy-Five limousine). After all, it was a Mercedes-Benz competitor, so why not charge Mercedes-Benz prices, right?

Price didn’t seem to deter many buyers from the Seville, as they came in droves from every direction, buying and quickly embraced this “small Cadillac”. The Seville succeeded in attracting both new and previous Cadillac owners, with roughly 60% of Seville buyers first-time Cadillac owners, and 15% of Seville buyers coming from luxury import brands such as Mercedes-Benz. Additionally, approximately 45% of Seville drivers were female, nearly double that of any other Cadillac.

The Seville proved that even when succumbing to outside forces and building a smaller car, Cadillac still could do it mostly on their terms. While the Seville offered a more maneuverable, European-like size, it made little concession to the traditionally soft ride and handling characteristics Cadillac buyers came to expect.

By largely sticking to their brash, set way of doing things, in some ways Cadillac and GM might have made too few concessions with the Seville, solving one problem but ultimately leading to many more down the road. The GM Deadly Sin angle of this first-generation Cadillac Seville has already been played, so let’s leave it at that.

Regardless, in its own right the Seville was a successful car, selling some 200,456 units in four years and proving that Cadillac could build a successful small car. More importantly, it brought more female buyers, first-time Cadillac buyers, and import buyers to the brand. The Seville also was responsible for setting the direction of style for virtually every new GM car for the next decade. Most lastingly, the Seville represented Cadillac’s first attempt at a competitive import fighter, something the brand has been trying to perfect with some actual success on and off again ever since.
