The Cadillac Seville is a luxury car that was manufactured occasionally by the Cadillac division of American automaker General Motors as a specialty model in the 1950s and 60s, and a regular production vehicle from 1975 to 2004. The Seville was traditionally second in the Cadillac lineup after the top-rung Eldorado, and more focused on technology than the sales-leader Deville.

The Seville, introduced in 1975, was Cadillac's answer to the rising popularity of luxury imports in the US from Europe, such as Mercedes-Benz and BMW. Historically, these imported luxury cars had been cheaper, less luxurious and significantly smaller than Cadillacs, but over time they had evolved, and had become quite luxurious and even more expensive than competing Cadillacs, and yet the market share of these imports continued to climb. It became obvious that the traditional American automotive paradigm of "bigger equals better" was no longer in full effect in the marketplace. The Seville became the smallest - and most expensive - Cadillac in the lineup, turning Cadillac's traditional marketing and pricing strategy on its head.

The first use of the Seville name was on a hardtop version of the 1956 Cadillac Eldorado convertible. Four Eldorado Seville 4-door hardtops were built in 1957, but it is the outlandish tailfins found on the 1959 model that are most remembered. 1960 was the last year for the Eldorado Seville.

Various names were considered for the proposed next generation Seville (1976). Resurrection of the LaSalle nameplate was seriously considered, but it was decided that given that LaSalle had been used for entry-level sub-Cadillacs in the past; it would create confusion in the marketplace among those who recollected the context of the names previous use.

Initially based on the rear-wheel drive X-body platform that underpinned the Chevrolet Nova (a unibody with a bolt-on subframe — this layout was common with both GM X and F bodies), the Seville's unibody and chassis were extensively re-engineered and upgraded from that humble origin and it was awarded the unique designation of "K-body". Cadillac stylists added a crisp, angular body that set the tone for GM styling for the next decade, along with a wide-track stance that gave the car a substantial, premium appearance. A wide chrome grille flanked by quad rectangular headlamps with narrow parking and signal lamps just below filled the header panel, while small wrap-around rectangular tail lamps placed at the outmost corners of the rear gave the appearance of a lower, leaner, and wider car.

Seville engineers chose the X-body platform instead of the German Opel Diplomat in response to GM's budget restrictions — GM executives felt that rebadging a German Opel would be more costly than the corporate X-car. Another proposal during the development of the Seville was a front-wheel drive layout similar to the Cadillac Eldorado. This proposal also met with budget concerns since the transaxle used for the Eldorado was produced on a limited basis solely for E-body (Eldorado/Toronado) production.

This was the first time Cadillac began engineering one of its vehicles based on components previously used in a Chevrolet model.

Introduced in mid-1975 and billed as the new "internationally-sized" Cadillac, the Seville was almost 1,000 lb (450 kg) lighter than the hulking Deville; nimble, easy to park, attractive and loaded with the full complement of Cadillac gadgets. More expensive than every other Cadillac model at US$12,479, the Seville was a smash hit, and spawned several imitators, such as the less-than-successful Lincoln Versailles, and later the Chrysler LeBaron/Fifth Avenue.

Early Sevilles produced between April 1975 (a total of 16,355) to the close of the 1976 model year were the first Cadillacs to use the Chevrolet passenger car wheel bolt pattern (5 lugs with a 4.75 in bolt circle; the 2003-present XLR also uses the Chevrolet pattern). The first Sevilles shared only a strict minority of components with the engineering starting point, the GM X-Body. The rear drums measured 11 in and were similar to the ones used with the Chevrolet Nova 9C1 (police option) and A-body (Chevelle, Cutlass, Regal, LeMans) intermediate station wagons. Starting with the 1977 model year, production Sevilles used the larger 5 lug — 5 inch bolt circle common to full-size Cadillacs, Buicks, Oldsmobiles, Pontiacs, and 1/2 ton Chevrolet/GMC light trucks and vans. It also received rear disc brakes, a design which would surface a year later as an option on the F-body Pontiac Trans Am.

Under the hood went an Oldsmobile-sourced 350 in³ (5.7L) V8, fitted with Bendix/Bosch electronically controlled fuel injection. This system gave the Seville smooth drivability and performance that was usually lacking in other domestic cars of this early emissions control era. Power output was 180 hp, and performance was restrained with the 60 mph sprint taking 11.5 seconds. A diesel 350 in³(5.7 L) LF9 V8 was added in 1978, but that engine was known to be poor in both performance and reliability.

The Seville Cadillac was manufactured in Iran under the brand name of "Cadillac Iran" during 1970s and 1980s, by Pars Khodro, which was known as "Iran General Motors" in 1970s.

For the 1980 model year, Cadillac moved the Seville to the 114 in wheelbase K-body platform, based on the front-wheel drive E-body Eldorado, Buick Riviera and Oldsmobile Toronado. Returning to some of the original concepts floated for the 1975 edition, stylists created a graceful but controversial bustle-backed body intended to invoke Daimlers of a past era (though British Leyland were building cars with this feature even then), and engineers gave it front wheel drive and independent rear suspension. Again, this spawned stylistic imitators such as the Lincoln Continental and the 1981 Imperial.

In hip hop culture, this generation of Sevilles were known as "slantbacks", especially with the factory-optioned wire rims (known as "suicides" or "swangas").^{[citation needed]}

Sales were strong at first, but disastrous flirtations with diesel engines (an Oldsmobile sourced 5.7 V8, plagued with head gasket problems)and the ill-fated V8-6-4 variable displacement gas engine,(a sound idea in theory- today manufacturers have made this system reliable, eg the Chrysler 300C - however back then the technology did not exist to make it work as it should) coupled with poor quality control and lacklustre performance from by now severely detuned engines to meet ever more stringent CAFE standards began to erode the Seville's standing in the marketplace. A new 4.1 litre V8 was fitted to post-82 models, but unfortunately this was prone to the block becoming porous and coolant mixing with the oil resulting in catastrophic engine failure. Some later cars were also fitted with the 4.1 litre Buick-derived V6, which was a reliable enough engine but however was not designed for fitment to "full size" cars and performance was rather lacking.

In the 1991 action film The Last Boy Scout, Milo (the main villains number 2) drives a "bustleback" Seville which he also crashes into a backyard pool while chasing the protagonists.

In 1986, an all-new, much smaller body attempted to combine the crisp angularity of the original Seville with the rounded edges of the new aerodynamic aesthetic. The series featured a transverse mounted V8 driving the front wheels. The styling result was regarded as bland, and customers stayed away. Despite the lack of popularity, the new Seville/Eldorado chassis featured an advanced transmission and engine control system that offered amazing MPG figures of nearly 30 on the highway using a small fuel injected V8. The new model featured a worldwide production car first — a computer system that monitored the car's systems and the engine. The electronic dashboard using high intensity vacuum fluorescent displays was unique worldwide. The BCM/ECM (Body Computer Module/Engine Computer Module) utilized GM's expertise derived from the acquisition of Hughes Electronics, makers of communications and spy satellites. This expertise was later carried forward to many GM models and brands making GM the leader in cutting edge electronics for automotive use. Unfortunately, the new model was considered a disaster with sales way below expectations, and an exterior refresh was rushed for 1988. The 1986-1991 Seville/Eldorado chassis may have been ahead of its time. The big news that year was the introduction of the Seville that had a Touring Suspenstion, it was referred to as a STS in latter years but was not! The initials were the same, this Seville gave way to the up coming 1989 Seville STS, which featured enhanced handling and styling and was only a four place car.

For 1992, Cadillac delivered a new, much more European-flavored Seville with looks that attracted rave reviews as well as customers. The Seville Touring Sedan was Motor Trend magazine's Car of the Year for 1992. It also made Car and Driver magazine's Ten Best list that year.

The 1993 addition of the Northstar System, including the Northstar quad-cam 32-valve aluminum V8 and a new unequal-length control arm rear suspension to the STS helped put the Seville back on the best seller list.

The rear suspension previously featured a single transverse leaf spring like the Chevrolet Corvette. The wheelbase was back up to 111 in with a 203.9 in overall length.

The Seville was divided into two sub-models:

• The Seville Luxury Sedan (SLS) started with the 4.9 L HT-4900 V8 but got a 270 hp LD8 Northstar V8 for 1994
• The Seville Touring Sedan (STS) also started with the 4.9 L HT-4900 in 1992 but was upgraded to the 295 hp L37 Northstar in 1993

Pricing on both cars was over US$40,000.

In the film U.S. Marshals, Tommy Lee Jones commandeers a Seville STS. Jewelry thieves in the movie Daylight drive a stolen Seville through Holland Tunnel before crashing into a chemical-laden truck. In the film Heat, Robert De Niro drives a green Cadillac Seville throughout the early parts of the film.

The Seville was updated for 1998 on a new revision of the K-body platform based on Oldsmobile's G-body Aurora. In 1997, the Cadillac Catera took over from the Seville as Cadillac's small car. The wheelbase was up to 112.2 in but the overall length was down a bit to 201 in. The car looked similar to the outgoing fourth-generation model that was plagued by build quality problems, but was considered a leap forward and featured numerous suspension and driveablity improvements. The Seville STS (and companion Eldorado ETC) became the most powerful front wheel drive cars on the market at 300 hp (224 kW). The fully-loaded STS model delivered at an MSRP of $52,075.

That particular generation was the first Cadillac to be entirely engineered to be built in both left- and right-hand-drive form. (Catera didn't count as it started out as the Opel Omega). In the past, the right-hand-drive Cadillac had been done with the CKD kits or special conversion kits shipped to the certain countries for local conversion. That generation was the first modern Cadillac ever to be officially imported and sold in South Africa along with other right-hand-drive markets such as the UK.

The cars got a new MagneRide adaptive suspension system in 2003. The fifth generation Seville was discontinued for 2004, replaced by the rear wheel drive Cadillac STS. Production of the front-wheel drive Seville STS ended on May 16, 2003 and the SLS ended on December 5, 2003. All front-wheel drive Sevilles were built in Hamtramck, Michigan.
