1980 Buick Regal Coupe, 1980 Buick Regal Sport Coupe, 1980 Buick Regal Limited, 1980 Buick Regal Somerset.
The year 1980 was a crossroads for the American automobile. The hangover from the 1970s fuel crises was still palpable, yet the public’s appetite for personal luxury and style had not waned. Into this complex market drove the Buick Regal, a nameplate that had successfully navigated the industry’s downsizing trend two years prior. Built on General Motors’ new, more efficient rear-wheel-drive A-body platform (soon to be re-designated the G-body), the 1980 Regal was a masterclass in market segmentation. It wasn’t just one car; it was a canvas upon which Buick painted four distinct automotive personalities. From the sensible base coupe to the opulent Somerset, each model catered to a specific buyer, creating a hierarchy of style, performance, and luxury. Let’s dissect the key differences between the 1980 Buick Regal coupe, Sport Coupe, Limited, and Somerset.
The Foundation: The 1980 Buick Regal Coupe
The Standard Bearer
The base Regal coupe was the foundation of the lineup and the volume seller. It offered the crisp, “sheer look” styling that defined the (earlier) 1978 redesign—a formal roofline, a classic vertical-bar grille, and balanced proportions—at an accessible price point. This was the car for the buyer who wanted Buick prestige, comfort, and reliability without the ostentation or added cost of higher trims.
Specifications and Features:
- Standard Engine: The heart of the base Regal was Buick’s own 3.8-liter (231 cubic inch) V6 engine. For 1980, this naturally aspirated stalwart produced a modest 110 horsepower and 190 lb-ft of torque. It was mated exclusively to a three-speed automatic transmission. The focus was on smooth, adequate power and reasonable fuel economy for the era.
- Exterior: The base coupe was understated. It featured dual rectangular headlamps, bright chrome bumpers, full wheel covers, and minimal side trim. The overall look was clean and elegant, a blank slate compared to its more decorated siblings.
- Interior: Inside, the base Regal was comfortable but not lavish. It featured cloth or vinyl bench seats, a standard instrument panel with a speedometer and fuel gauge (lacking a tachometer or full instrumentation), and manual windows and locks. Air conditioning, a radio, and other comforts were common options.
- Pertinent Information: This model represented the core value proposition of the Regal line. It provided a quiet, comfortable ride—a hallmark of the Buick brand—in a stylish, contemporary package. It was the starting point from which all other Regals were born.
The Athlete: The 1980 Buick Regal Sport Coupe
A Glimmer of Performance
While the malaise era had largely extinguished the muscle car flame, Buick was quietly kindling a new kind of fire with the Regal Sport Coupe. This was not a tire-shredding monster of the 1960s, but a more sophisticated and technologically advanced take on performance. Its secret weapon was under the hood: turbocharging.
Specifications and Features:
- Standard Engine: The sole engine for the Sport Coupe was the 3.8-liter (231 CID) Turbocharged V6. This innovative “draw-through” carbureted turbo system boosted output significantly to 170 horsepower and an impressive 265 lb-ft of torque. This was serious performance for 1980, offering V8-like acceleration with the potential for better V6 fuel economy when driving off-boost. A subtle “Turbo 3.8 Litre” badge on the hood bulge was the only hint to the uninitiated.
- Exterior: The Sport Coupe shed the base model’s chrome in favor of a more aggressive, contemporary aesthetic. It featured full blacked-out trim around the windows, grille, and headlamp bezels. A discreet front air dam and rear spoiler added to the sporty look. It rode on specific 14-inch sport wheels, often with turbine-style fins, and featured bold “Sport Coupe” graphics on the rear fenders. The most distinguishing feature was the power bulge on the hood, necessary to clear the turbocharger and carburetor assembly.
- Interior: The driver-focused interior featured standard bucket seats, a sport steering wheel, and a full gauge package that included a tachometer and a turbo boost gauge. The ride was firmed up with a specific sport suspension package that included larger diameter sway bars for improved handling.
- Production Numbers: The Sport Coupe was a niche model for enthusiasts. For the 1980 model year, approximately 9,092 Regal Sport Coupes were produced, making them relatively rare finds today. They are the direct ancestors of the legendary Buick Grand National that would arrive later in the decade.
The Aristocrat: The 1980 Buick Regal Limited
Plush Personal Luxury
If the Sport Coupe was for the spirited driver, the Regal Limited was for the traditional Buick buyer who prioritized comfort and luxury above all else. The Limited was a direct descendant of the grand, opulent coupes of the past, now presented in a more modern and efficient package. It was the most popular trim level, proving that in 1980, comfort was still king.
Specifications and Features:
- Engine Options: The Limited came standard with the same 110-hp 3.8L V6 as the base model. However, it opened the door to optional V8 power. Buyers could select a 4.9-liter (301 CID) V8 sourced from Pontiac (140 hp) or a 5.0-liter (305 CID) V8 from Chevrolet (155 hp), providing smoother and more effortless acceleration.
- Exterior: The Limited distinguished itself with a generous application of chrome and upscale details. It featured a unique formal padded landau vinyl roof with “Limited” script and opera lamps on the B-pillars. Wide chrome rocker panel moldings, bodyside moldings with a vinyl insert, and specific “Limited” badging announced its premium status. Wire wheel covers were a ubiquitous and popular option.
- Interior: The cabin was the Limited’s true calling card. The standard seating was a plush, 60/40 split-bench front seat upholstered in “loose-pillow” style velour, designed to look and feel like high-end living room furniture. The door panels were more ornate, woodgrain applique adorned the dash, and amenities like power windows, power locks, cruise control, and a tilt steering wheel were often standard or very commonly optioned. The focus was on creating a serene, isolated environment for the driver and passengers.
The Pinnacle: The 1980 Buick Regal Somerset
Bespoke Elegance
At the very top of the Regal hierarchy was not a separate model, but a special luxury package available exclusively on the Regal Limited: the Somerset. The Somerset package was for the buyer who wanted the most distinctive and opulent Regal available from the factory. It was an exercise in two-tone style and bespoke detailing.
Specifications and Features:
- An Option Package: It is crucial to note the Somerset was a “Limited Edition” package (Code Y56) applied to a Regal Limited. Therefore, it shared the same engine and mechanical options as the standard Limited.
- Exterior: The Somerset’s appearance was its most defining characteristic. It was available in only two exclusive two-tone paint schemes: a rich Dark Claret over a Light Claret, or a sophisticated Dark Blue Metallic over a Light Blue Metallic. The colors were separated by a bold accent stripe. Standard equipment included body-colored sport mirrors and designer series wire wheel covers.
- Interior: The interior received an equally unique treatment. The seats were finished in a special tan or blue velour and featured embroidered “Somerset” crests. The door panels and trim were color-keyed to match the exclusive exterior palette. A sport steering wheel and unique “Somerset” badging on the dashboard completed the bespoke feel.
- Production Numbers: Being a premium, limited-run package, the Somerset is the scarcest of the 1980 Regals. While precise numbers for the package are difficult to isolate, it is estimated that only a few thousand were produced, making them a true prize for Buick collectors today.
Summary of Production and Market Position
For the 1980 model year, Buick produced a total of 244,146 Regal coupes across all trim levels. The vast majority of these were the base and Limited models, which perfectly captured the mainstream desire for affordable personal luxury. The Limited, in particular, was a runaway success. The Sport Coupe, with its 9,092 units, was a successful experiment in proving that American performance could be found in a smaller, turbocharged package. The Somerset represented the ultimate expression of the Regal’s luxury potential, a low-volume halo package that added an extra layer of exclusivity.
In retrospect, the 1980 Buick Regal lineup was a brilliant strategy. Using a single, handsome platform, Buick managed to be all things to all people: an economical and stylish daily driver, a forward-thinking performance car, a traditional luxury cruiser, and a top-tier special edition. This versatility not only ensured the Regal’s success in 1980 but also cemented its place as one of the most significant and beloved American cars of its era.
