. The Regal also serves as the basis of the high-performance Grand National, Gran Sport (GS), and Buick GNX coupes. Through its production, the Regal has been marketed under a wide variety of body styles, including two-door coupes and four-door sedans (currently in production), along with a 5-door liftback sedan and a 5-door station wagon; the latter (the 2018-2020 Regal TourX) was the first Buick station wagon marketed since the retirement of both the Century and Roadmaster Estates after 1996. The turbocharged LD5 3.8L V6 used in the second generation was used to showcase the motorsports presence of the brand; though offered with other vehicles (including Chevrolets and Pontiacs), the turbocharged engine is most commonly associated with the Regal. During the 1990s, the V6 regained forced induction, with a supercharger replacing the turbocharger. In 1999, General Motors commenced sales of its vehicles in China, with the Buick Regal serving as its introductory model of the joint venture

coupe; repackaging it as an equivalent of the Grand Prix proved successful, as it became the brand's best-selling intermediate. For 1973, GM introduced the "Colonnade" generation of its A-body intermediates. Developed in anticipation of increased rollover safety standards, GM eliminated hardtop rooflines completely (in favor of visually reinforced roof pillars); the designs were marketed as " pillared hardtops" (retaining frameless door glass on all body styles). Buick dropped the Skylark nameplate from its A-body range, replacing it with Century (last used in 1958 on its flagship B-body). As with other Colonnade intermediates, the Century was offered as a two-door and four-door sedan and a five-door station wagon. After lagging behind Chevrolet, Oldsmobile, and Pontiac, Buick introduced an intermediate-size personal coupe for 1973, marketing the "Century Regal

Hardtop coupe". Along with a notchback roofline (with side opera windows), the Regal featured its own grille and taillamp lenses.


First generation (1973)

For 1973, Buick introduced the Century Regal as the flagship model of its A-body intermediate line. As with the lower-priced Century Luxus coupe, the Regal shared its notchback roofline with the Chevrolet Monte Carlo, Oldsmobile Cutlass Supreme, and Pontiac Grand Prix. For 1974, the Century Regal adopted a four-door sedan from its parent line, which featured a slightly fastback roofline (the Colonnade station wagon only carried the Century Estate nameplate). For 1976, the Buick Regal became a distinct model line slotted above the Century. Interiors were upgraded over standard Century trims, with Regals featuring woodgrain trim on the dashboard and door panels (equipped with door-pull straps).

s with folding center armrests were standard, upholstered in either cloth, velour, or vinyl upholstery; a 60/40 split-bench seat was optional. The 1976-1977 Regal S/R coupe was offered with reclining bucket seats with corduroy upholstery. The Colonnade-generation Regal saw relatively few changes through its production. Following revisions related to the 1974 addition of 5-mph bumpers, the front fascia underwent an update for 1976, incorporating rectangular-lens quad headlamps (horizontally-mounted on coupes, vertically stacked on sedans). Over 500,000 Regal coupes were sold during this generation, though the model lagged behind the Monte Carlo and Cutlass Supreme; the latter had become among the best-selling car lines in America by 1976. The listed retail price for a 1976 Regal was $4,910 ($ in dollars ).


Powertrain details

The Regal was most commonly powered by a Buick V8, which was the standard engine for 1973 and 1974; a Buick V8 was optional. For 1975, Buick intermediates dropped the 455 V8, with the 350 V8 becoming an optional engine for Regal coupes. For 1975, a V6 became the standard engine. Designed by Buick, the V6 was developed for its initial Special/Skylark compacts in the early 1960s. In 1967, the tooling for the engine was sold to
Kaiser Motors Kaiser Motors (formerly Kaiser-Frazer) Corporation made automobiles at Willow Run, Michigan, United States, from 1945 until 1953. In 1953, Kaiser merged with Willys, Willys-Overland to form Willys Motors Incorporated, moving its production ...

Power remained unchanged until 1982, when it increased to and then in 1983, when the Sport Coupe was replaced by the Regal T-Type. In February 1982, the Grand National debuted, which was named for the NASCAR Winston Cup Grand National Series (the "Grand National" term was part of the Cup series nomenclature until 1986). Buick had won the Manufacturers Cup in 1981 and 1982, and wanted to capitalize on its success: "What wins on Sunday, sells on Monday", and hoping to revive their performance image from the 1960s with the Buick Skylark Gran Sport. These 1982 cars were not painted black. All examples started out as charcoal gray Regals that were shipped off to a subcontractor for finishing.

These seats are fully adjustable and were covered with silver brandon cloth with black vinyl inserts. The front seat had Buick's "6" emblem embroidered onto them. Also, a special clock delete plate was added to the instrument panel which contained the yellow and orange "6" logo and the words "Grand National Buick Motor Division".) The 1982 GN came with a

There were only 2022 Sport coupes produced in 1982, and the number of cars with both the GN and Sport coupe packages is estimated to be fewer than 50. For 1983, there was no Grand National. The Sport Coupe model was renamed the T-Type; 3,732 were produced ( at 4000 rpm and of torque at 2400 rpm). The power gains came courtesy of a low-restriction dual exhaust, stainless steel headers (rather than the original cast iron items), and other detail improvements. Drivability was improved thanks to better electronics for the exhaust gas recirculation system as well as the knock sensor. The T-Type trim name had been used on other Buicks, starting with the

Buick dropped the T-Type package for Regal for 1987 models and opted for a "T" sport package instead. There were only 7,896 turbo Regals produced in 1986. In 1987, when turbo Regals reached their peak in popularity, a total of 27,590 turbo Regals were produced through December, with those models produced between September and December of that year window stickered as "1987½ Buick Grand National" vehicles. For 1987, a lightweight WE4 option was offered. Only 1,547 of this variant were produced.

The rear spoiler was only available as a dealer-installed option. 1987 was the only year that the LC2 turbo option was available on any Regal, making it possible to have a Limited with a vinyl landau roof and a power bulge turbo hood. Turbo Regal Limiteds were one of the rarest models of turbo Regals produced second only to the GNX at 1,035 turbo Limiteds. Turbo Regal Limiteds could be ordered with many options with most having chrome external trim but for $35 could have been built with the full black-out trim WO2 option making them extremely rare (similarly, a base Regal could also be ordered with the Turbo 6, and, the WO2 blackout trim was also available; all rare). Limiteds were treated to a very luxurious interior with plush carpeting and optional bench pillow seats and a column shift. It was also possible to order the 1987 Regal T with the 5.0/307 V8 instead of the turbo 3.8/231 V6. The 1987 model would be the end of the manufacture of the RWD "G-Body" Regal, but GM had to extend the build of the Grand National to meet customer demand into December.

The torque arm rear suspension alters the suspension geometry, making the body lift while planting the rear tires down, resulting in increased traction. GNX #001 is the 1986 prototype currently owned by Buick and sometimes makes appearances at car shows around the US.

Third generation (1988)

A new Regal appeared in October 1987 on the GM W platform as the first vehicle on that platform; this generation ran with few changes for nine years. Though the new Regal returned to Buick's original concept in being offered only as a coupe and in being aimed once again squarely at the personal luxury buyer, it departed from tradition in being the first front-wheel-drive model, and in having no serious performance option or edition. Neither a

nor a turbocharged V6 was offered; the only engine available for 1988 was the Chevrolet 2.8 L V6, producing . From mid-1990, owing to the declining personal luxury car market, a four-door sedan version of the Regal was re-introduced (simultaneously as the Cutlass Supreme and Grand Prix, the latter offered as a sedan for the first time). However, sales of the new sedan were delayed until the 1991 model year. The four-door version was intended as a replacement for the A-body based

, however, the popularity of that model meant that it would remain in production as a lower priced alternative to the Regal until both cars were redesigned for 1997. This generation saw the installation of Dynaride, which was an air compressor that would pressurize the rear Chapman Struts to maintain a level overall ride height. A badge was installed on the dashboard to the left of the steering column on all vehicles equipped. It was not available on vehicles equipped with Gran Touring Suspension, which instead used a stiffer setup with traditional hydraulic rear struts.

Annual changes

The Regal was initially offered in base ''Custom'' and upscale ''Limited'' trim lines. For 1989, the '' Gran Sport'' trim line was added, featuring aluminum wheels, body side cladding and a console-mounted shifter attached to the 4-speed automatic. In mid-1990, the Regal gained the option of the Buick 3.8 L V6 with "Tuned-Port-Injection" (TPI). The 3800 V6 was unique to the Regal amongst the W-body cars, differentiating it from the mechanically similar

With an advertised 30 more horsepower than stock, the Stage 3 GSX was conservatively rated at and of torque. As GSX parts remained directly available from SLP for many years, Regal GS sedan owners could have their cars independently customized to GSX appearance and performance by SLP dealers, including for Regal GS models from 1997 to 2004. An authentic Buick GSX can be verified from an SLP door jamb label with the correct part number for the kit.

On April 4, 2017, GM presented the sixth-generation 2018 Buick Regal at the GM Design Dome in
Warren, Michigan Warren is a city in Macomb County, Michigan, Macomb County in the U.S. state of Michigan. An inner-ring Metro Detroit, suburb of Detroit, Warren borders Detroit to the north, roughly north of downtown Detroit. The population was 139,387 at the ...
; sales of the model line began in China on July 21, 2017. As with the Buick Cascada, the Regal became a captive import, as Buick sourced production of the model line entirely from Opel in Rüsselsheim. Derived from the Opel/Vauxhall Insignia B, the American-market Regal also gained a third divisional counterpart, as the model became the basis of the Holden ZB Commodore (the final generation of the Commodore line). The Regal moved to the GM E2XX (third-generation Epsilon) platform, adding 3.6 inches of wheelbase. While most closely related to the ninth (final) generation Chevrolet Malibu, it also shared its underpinnings with the third-generation Buick LaCrosse. Though growing in size, a key objective of the platform update was weight reduction, with of curb weight removed. In a major design change, the Regal four-door sedan became exclusive to China, with all Regal sedans in North America moving to a five-door liftback configuration. The Regal TourX station wagon was introduced for 2018, becoming the first Regal station wagon since 1983.


Regal Sportback

Replacing the previous Regal four-door sedan, the Regal Sportback is a 5-door liftback sedan; the hatchback was incorporated within a fastback roofline, allowing for additional cargo room and flexibility. Buick offered three standard trims: 1SV (base), Preferred, and Essence, along with the flagship Avenir trim. The Sportback also served as the basis of the high-performance Regal GS (see below). Fitted with a 250hp '' LTG'' 2.0L turbocharged I4 engine, the Sportback was offered with either front-wheel drive ( of torque, 9-speed automatic) or optional all-wheel drive ( of torque, 8-speed automatic).

Regal TourX

The Buick Regal TourX is a 5-door station wagon, serving as the divisional counterpart of the Opel/Vauxhall Insignia Country Tourer and the Holden Commodore ZB Calais Tourer. Developed as a rugged-style station wagon with plastic body cladding, slightly raised ride height, and standard all-wheel drive, the TourX was developed as a competitor of the

and the Volvo Cross Country lines, though marketed towards sportier touring than heavier off-road use. The Insignia Country Tourer was a body style introduced during the previous generation, but was ultimately not produced or imported by GM. The first Regal station wagon in 35 years, the 2018 TourX was the first Buick station wagon of any kind since the 1996 retirement of the Roadmaster and Century Estates. Sized between the Subaru Outback and Volvo V90, the TourX was one of the largest station wagons sold in North America; its 73.5 cubic feet of cargo space matched the Outback and was the most of any Buick (with the exception of the three-row

). Buick offered the TourX with three trims: 1SV (base), Preferred, and Essence (the Avenir and GS were not offered) Fitted with the 250hp '' LTG'' turbocharged I4 ( of torque), the TourX only used an 8-speed automatic transmission.

Regal GS

The Regal GS (Gran Sport) is the highest-performance version of the Buick Regal. Returning from the previous generation, the Regal GS is the counterpart of the Opel/Vauxhall Insignia GSi (replacing the previous OPC) and the Holden Commodore VXR. In keeping with the previous generation, the GS featured a higher-performance powertrain, sportier styling, and upgrading suspension and brakes. In a major change, the GS now shared the standard all-wheel drive of its Opel counterpart. The GS shared its liftback body with the Regal Sportback, but the exterior is fitted with its own grille, front and rear bumpers, 19-inch wheels (the previous 20-inch wheels were retired), and an integrated decklid spoiler. The interior was fitted with heavily-bolstered front seats, a digital instrument cluster, and GS-specific trim. As the turbocharged LTG from the previous GS became the standard engine for the Sportback and TourX (retuned slightly), the E2XX GS adopted its 310hp 3.6L V6 engine from the Holden Commodore and Buick LaCrosse, paired with a 9-speed automatic transmission. The most powerful Regal ever produced, the 2018-2020 GS was the first vehicle in the model line to eclipse the official (rated) power output of the 1987 Buick GNX.

Regal (China)

For China, 2018 brought a third-generation Regal, as

began local production of the Opel Insignia B, marketing it between the Verano and LaCrosse sedans. While sharing the E2XX platform and a visually similar exterior, the SAIC-produced Regal differed substantially from its Opel-designed counterpart, as it was designed as a four-door sedan with a traditional decklid. In China, neither the Sportback nor the TourX have been sold; the four-door has never been exported under any nameplate. The Chinese-market Regal (sold in front-wheel drive only) was initially sold in four trims: 20T (1.5L turbo I4), 28T (2.0L turbo I4), GS (2.0L turbo I4), and 30H hybrid (1.6L I4 + EV motors). Turbocharged Regals were fitted with a 9-speed automatic transmissions while the hybrid was fitted with a CVT. SAIC-GM Regals were visually similar to Opel-assembled units, with non-GS vehicles closest in design to Essence-trim Sportbacks (though using the digital instrument panel of the GS). For 2021, the Regal underwent a model update, receiving a restyled grille and updated dashboard and center console (with a pushbutton gear selector). For 2022, the trim levels were reduced to Luxury and GS. For 2024, a second facelift, concentrating primarily on the front fascia, brought the Regal in line with the Buick "Pure Design" style (seen on Buick American SUVs), giving the model a revised Buick tri-shield emblem. As a running change during 2025, SAIC-GM debuted a third facelift for the GS, combining the 2018-2023 grille size with the updated Buick tri-shield. In response to poor feedback to the "Pure Design" facelift, the company also introduced the updated GS front fascia as a replacement body kit.

Discontinuation

In December 2019, General Motors announced that it would stop importing the Buick Regal for North America after the 2020 model year. Following the 2020 withdrawal of the Cascada and LaCrosse, Buick ended its 113-year run of manufacturing and marketing cars, that is sedans and sedan derivatives, in North America — in favor of
