1981 Buick Regal coupe, 1981 Buick Regal Sport Coupe, 1981 Buick Regal Limited, 1981 Buick Regal Somerset, 1981 Buick Regal Indy Pace Car.
In the automotive landscape of 1981, American manufacturers were navigating a complex world of fuel crises, emissions regulations, and a public yearning for a return to style and performance. It was a transitional period, and few cars embodied this multifaceted era better than the Buick Regal. For 1981, the Regal received a significant redesign, a sleek, aerodynamic facelift that would define its iconic shape for the rest of the decade. But beyond the new sheet metal, Buick offered a surprisingly diverse portfolio under the Regal nameplate, catering to a wide spectrum of buyers. From the economical base model to the turbocharged performer and the opulent luxury editions, the 1981 Regal was not one car, but a family of distinct personalities. This article delves into the five key variants: the Regal Coupe, Sport Coupe, Limited, Somerset, and the ultra-rare Indy Pace Car Replica.
The Foundation: 1981 Buick Regal Coupe
The standard Buick Regal Coupe served as the accessible and stylish foundation for the entire line. It was the volume seller, designed to offer the brand’s signature “personal luxury” experience at an attractive price point.
Styling and Features: The 1981 redesign gifted the base Regal with a handsome, forward-canted grille featuring vertical chrome bars, dual rectangular headlamps per side, and a formal, upright roofline. The new bodywork significantly improved its coefficient of drag, a key selling point in an era of high gas prices. Standard equipment was modest but respectable, including color-keyed seatbelts, a lighter, deluxe wheel covers, and cloth-and-vinyl bench seating. The interior was clean and functional, with a simple dashboard layout and minimal ornamentation. It was a blank canvas, ready to be customized from Buick’s extensive options list.
Specifications and Powertrain:
- Standard Engine: The workhorse 3.8L (231 cid) 2-barrel V6, producing a humble 110 horsepower and 190 lb-ft of torque.
- Optional Engines: Buyers could opt for a larger 4.1L (252 cid) V6, a 4.3L (265 cid) V8 sourced from Pontiac, or even a 5.7L (350 cid) diesel V8 for maximum fuel economy.
- Transmission: A standard 3-speed Turbo-Hydramatic 200 automatic transmission handled shifting duties.
- Suspension: The standard suspension was tuned for comfort above all else, providing a soft, absorbent ride characteristic of Buick.
Production: As the base model, the standard coupe and its luxury counterpart, the Limited, accounted for the vast majority of the approximately 285,000 Regals produced in 1981. It was the bedrock of the Regal’s success.
The Performer: 1981 Buick Regal Sport Coupe
While the base Regal focused on comfort, the Sport Coupe was a harbinger of the performance revolution to come. It was Buick’s factory-built muscle car for the new decade, subtly packaging a turbocharged secret under its hood and laying the groundwork for the legendary Grand National.
Styling and Features: Visually, the Sport Coupe was a master of understatement. Its most prominent identifier was the slight “power bulge” in the middle of the hood, needed to clear the turbocharger and carburetor assembly. Other cues included blacked-out grille and headlamp bezels, firm-ride-and-handling suspension (Buick’s F41 package), a rear spoiler, and distinctive “Turbo 3.8 Litre” badges on the fenders and trunk lid. Many were ordered with sporty two-tone paint schemes and cast aluminum turbine-style wheels. Inside, bucket seats and a center console were common options, and the dashboard featured a series of small lights to indicate turbocharger boost levels.
Specifications and Powertrain:
- Standard (and only) Engine: The 3.8L (231 cid) Turbocharged V6 (engine code LC8). This innovative engine, featuring a four-barrel carburetor, produced a potent 175 horsepower and 275 lb-ft of torque—a massive leap over the standard V6 and competitive with many V8s of the day.
- Transmission: The turbocharged engine was mated to a more robust 3-speed Turbo-Hydramatic 350 automatic transmission to handle the significant increase in torque.
Production: The Sport Coupe was a niche vehicle for enthusiasts in the know. Only 3,203 were produced for 1981, making them significantly rarer than their V8-powered rivals from Chevrolet and Pontiac and a sought-after collectible today.
The Patrician: 1981 Buick Regal Limited
At the opposite end of the spectrum from the Sport Coupe sat the Regal Limited. This was the flagship luxury model, designed to appeal to the traditional Buick buyer who prized comfort, quietness, and a high level of standard features. It was a rolling statement of Brougham-era opulence in a more modern, efficient package.
Styling and Features: The Limited distinguished itself with an abundance of brightwork. It featured a unique, heavily chromed grille with finer vertical bars, chrome rocker panel moldings, chrome wheel arch trim, and a full, formal padded vinyl roof. Wire wheel covers were the standard, reinforcing its luxurious intent. The interior was its main selling point, featuring deeply cushioned, “loose-pillow” style 55/45 notchback front seats upholstered in plush velour. Woodgrain appliqué adorned the dashboard and door panels, and amenities like power windows, power locks, and a tilt steering wheel were either standard or very commonly optioned.
Specifications and Powertrain: The Limited shared its powertrain options with the base Regal Coupe. The focus was not on performance but on a smooth, silent, and effortless driving experience. The suspension was tuned for maximum softness, isolating occupants from the road.
Production: The Limited was a very popular trim level, making up a significant portion of the total 1981 Regal production figures, appealing to buyers who wanted a Cadillac-like experience in a more manageable size.
The Designer Edition: 1981 Buick Regal Somerset
For buyers who found the standard Limited not quite exclusive enough, Buick offered the Somerset Limited Edition package (RPO code A91). This was a special appearance package built upon the Limited trim, adding a touch of bespoke, designer flair.
Styling and Features: The Somerset was defined by its unique and elegant color scheme. The most common combination was a two-tone Dark Sandstone Metallic over a light Cream Beige, separated by a distinctive pinstripe. Its most striking feature was a special landau top, where the rear portion was covered in a brushed chrome finish rather than traditional vinyl, creating a stunning visual effect. Special “Somerset” badging and emblems adorned the C-pillars and dashboard. The interior was equally specific, featuring tan velour upholstery and color-keyed trim throughout, creating a harmonious and sophisticated cabin environment.
Specifications and Powertrain: As an appearance package, the Somerset carried the same engine and transmission options as the Regal Limited. It was all about visual distinction, not mechanical difference.
Production: Production numbers for specific trim packages like the Somerset are notoriously difficult to pinpoint, as they were often rolled into the total for the model they were based on (the Limited). However, it was a premium and relatively low-take package, ensuring its rarity on today’s roads.
The Celebrity: 1981 Buick Regal Indy Pace Car Replica
In 1981, Buick was given the honor of pacing the 65th Indianapolis 500. To commemorate this, the company produced a very small run of replicas for public sale. Based on the performance-oriented Sport Coupe, these cars were the ultimate expression of the 1981 Regal.
Styling and Features: The Pace Car was impossible to miss. It featured a striking two-tone Silver and Charcoal Gray paint scheme, accented with bold red and orange stripes. Massive “BUICK” lettering adorned the rear quarter panels, and official “65th Indianapolis 500 Mile Race” logos were placed on the doors. A functional front air dam and rear decklid spoiler, shared with the Sport Coupe, completed the racy look. T-Tops were a mandatory part of the package. The interior was unique, with black and gray cloth upholstery and special Indy 500 emblems embroidered on the door panels and front seat headrests.
Specifications and Powertrain: While the actual cars that paced the race used a highly modified 4.1L V6 for durability, the replicas sold to the public were equipped with the production 3.8L Turbocharged V6, identical to the one found in the Sport Coupe. This made them not just showpieces, but genuinely quick cars for their time.
Production: The 1981 Regal Indy Pace Car Replica is exceedingly rare. It is estimated that only 215 units were produced, making it one of the most collectible G-body vehicles of the era. Each one was a rolling piece of motorsports history, representing the pinnacle of Buick’s performance and marketing efforts for the year.
In conclusion, the 1981 Buick Regal was far more than a single car. It was a versatile platform that brilliantly captured the disparate demands of the era, offering everything from sensible transportation and plush luxury to turbocharged performance and collectible exclusivity, all under one proud and newly-sculpted nameplate.
