Buick Regal

In the full-size personal luxury car segment, Buick was the first GM division to market a vehicle (the 1963 Buick Riviera, debuting the GM E-body). As the segment expanded towards intermediate-size coupes, GM saw the introduction of a repackaged Pontiac Grand Prix for 1969 and an all-new Chevrolet Monte Carlo for 1970. The same year, Oldsmobile added a notchback roofline to its Cutlass Supreme 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 Colonnade 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). Bench seats 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 for use in Jeep vehicles (purchased by American Motors in 1970). In 1974, GM acquired the tooling and the rights to the V6 engine from AMC and reintroduced the Buick V6 engine for 1975. For 1975 and 1976, the Century and Regal were the only mid-size cars sold in America to offer V6 engines.

}} }} }} A downsized Regal appeared for the 1978 model year with Buick's new V6 engine as standard equipment and a revised version of the venerable V6 as an option (which became standard for 1980). Initially, a three-speed manual transmission was standard and a four-speed available, but the automatic option filled their places from 1980 onward. At the time of introduction, Regals were available exclusively as coupés with the Century nameplate applied to standard equipment sedans and station wagons. In January 1982 the Century was replaced by an all-new car on the front-wheel drive A platform, which meant that the Regal gained a four-door sedan and five-door station wagon - essentially facelifted and rebadged versions of the previous year's rear-wheel drive Century. It was the first time the name appeared on a full model lineup. The wagon was discontinued after 1983, and the sedan dropped from the lineup the next year. This generation Regal lasted ten years. The base model was equipped with softer-riding luxury suspension.

The Buick LeSabre was also available with the turbocharged engine, the only other turbocharged cars available in the U.S. market in 1978 being imports from Mercedes-Benz, Porsche and Saab. The Regal Sport Coupe also included a firm handling suspension with larger tires and sport wheels. Bucket seats and a center console with a T-shifter were available. For 1980, the Regal was offered in a special Somerset Limited Edition trim which featured unique tan and dark blue designer exterior paint, wire wheel covers, sport mirrors, and chrome Somerset badging. The interior had tan and blue plush velour upholstery, brushed chrome trim, and additional Somerset badging. A Somerset Limited Edition model was also offered on the restyled 1981 Regal. It had unique dark sandstone and camel exterior paint, sport mirrors, and turbine wheels. The interior's plush velour upholstery was camel with dark brown piping. A major facelift for 1981 gave the Regal a much more aerodynamic profile, helping make it possible for the car to compete on the NASCAR racing circuit. The sloping hood and nose of the car made it the favorite of several NASCAR teams, and reduced the drag coefficient by eighteen percent. Richard Petty drove one to victory in the 1981 Daytona 500, and the car won a majority of the 1981 and 1982 seasons races and won the NASCAR manufacturers title in 1981 and 1982. Buick would remain the last marque other than Chevrolet or Ford to win the Cup Series manufacturers championship until Toyota scored its first in 2016. It also propelled Buick to #3 in sales after 26 years, remaining in that place through 1983. V8s for street use were still available, but had shrunk to (1980 and 1981 only, Pontiac built), and the V6 was rapidly gaining popularity. From 1986 to 1987, the V8 was available as an option. The 2-bbl V6 was standard. The 200-4R overdrive transmission was an option with either engine. Production Figures: Grand National, Turbo-T and T-Type In 1978, the first turbocharged Regal was introduced as the Regal Sport Coupe. Turbo versions were originally offered with either a two- or a four-barrel carburetor and , but the two-barrel option was removed for 1979. Meanwhile, the four-barrel's maximum output increased to . Power remained unchanged until 1982, when it increased to and then in 1983, when the Regal T-Type replaced the Sport Coupe. 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. Originally intended for a run of 100 units, Cars and Concepts of Brighton, Michigan, retrofitted 215 Regals with the GN package. Most obvious was the light silver-gray Firemist paint added to each side. Red pinstripes and billboard shadow lettering proclaiming "Buick" were applied. The wheel opening moldings and rocker panel moldings were blacked out using black vinyl tape. Finally, a front air dam and rear spoiler were installed. On the inside, special "Lear-Siegler" seats were installed. 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 it. 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 naturally aspirated V6 engine with at 4000 rpm and of torque at 2000 rpm. Of the 215 Grand Nationals produced in 1982, at least 35 were based on the Buick Regal Sport Coupe package with the turbocharged V6 engine with at 4000 rpm and of torque at 2600 rpm. Only 2022 Sport coupes were 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 improved thanks to better electronics for the exhaust gas recirculation system and the knock sensor. Inside there were new bucket seats and a sport steering wheel and quicker steering ratio, while the suspension was honed with a larger diameter anti-roll bar, altered spring rates, and re-valved shock absorbers. For 1985, the Grand National remained unchanged. For 1986, a modified engine design with air-air intercooling boosted the performance even further to a specified at 4000 rpm and of torque at 2400 rpm. The Grand Nationals (quantity 5,512) and T-Types (quantity 2,384) were both produced in 1986. For 1987, performance increased 10 hp, to and of torque; however, no design revisions were made to the engine or systems. Buick dropped the T-Type package for Regal for 1987 models and opted for a "T" sport package instead. Only 7,896 turbo Regals were 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 differences between a WE4 and the Grand National were the interior trim package, wheels, exterior badging, aluminum bumper supports, and aluminum rear drum brakes, unlike the Grand National's cast iron, making the WE4 a lighter and faster car. The rear spoiler was only available as a dealer-installed option. 1987 was the only year the LC2 turbo option was available on any Regal, making a Limited with a vinyl landau roof and a power bulge turbo hood combination possible. Turbo Regal Limiteds were the second-rarest model of turbo Regals produced, after the GNX, at 1,035. 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 blackout trim WO2 option, making them extremely rare. Similarly, a base Regal could be ordered with the Turbo 6, and the WO2 blackout trim was also available. Limiteds were treated to a very luxurious interior with plush carpeting, 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. File:Buick T-Type (2669441886).jpg|Buick Regal T-Type File:WO2T.jpg|1987 Regal Turbo-T with rare blackout WO2 trim package GNX For the final year, 1987, Buick introduced the limited production GNX, for "Grand National Experimental", at $29,900 ($85,399 adjusted for inflation in ). Made in partnership with McLaren Performance Technologies/ASC, Buick produced only 547 GNs with the interior trim package, that were then sent off to McLaren and upgraded into the Buick GNX. Buick underrated the GNX at at 4400 rpm and a very substantial at 3000 rpm of torque, although actual output is and . This was created to be the "Grand National to end all Grand Nationals". Changes made included a special Garrett AiResearch T-3 turbocharger with a ceramic-impeller blowing through a more efficient and significantly larger capacity intercooler with a "Cermatel (ceramic-aluminum) coated" pipe connecting the intercooler to the engine. A GNX-specific EPROM, low-restriction exhaust with dual mufflers, reprogrammed turbo Hydramatic 200-4R transmission with a custom torque converter and transmission cooler, a unique differential cover, and panhard rod included more of the performance modifications. Exterior styling changes include vents located on each front fender, 16 inch black mesh style wheels with VR-speed rated tires, and deletion of the hood and fender emblems. The interior changes of the GNX included a serial number on the dash plaque and a revised instrument cluster providing Stewart-Warner analog gauges, including an analog turbo boost gauge. The GNX used a unique torque arm that was mounted to a special, GNX only, rear differential cover, for increased traction. 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. The stealthy appearance of the all-black GNX and Grand National (and the resemblance of its grille to his helmet's mouthpiece), coupled with the fact that the Grand National was initially released during the popularity of Star Wars movies, earned it the title "Darth Vader's Car.” Due to the turbocharged six-cylinder engine, the Buick make, and the black paint Grand Nationals were sometimes referred to as the "Dark Side". The "Dark Side" contrasted with the more common V8 Mustangs and Camaros that were popular at the time. GNX is the title for hip-hop artist Kendrick Lamar's 2024 album and its eponymous 11th track, and the car is on the album's cover art. == 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 V8 engine 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 3800 V6 was unique to the Regal amongst the W-body cars, differentiating it from the mechanically similar Chevrolet Lumina, Oldsmobile Cutlass Supreme, and Pontiac Grand Prix. Anti-lock brakes were made standard on all but the base Custom cars from 1992. For 1993, the Regal sedan received a minor facelift with a new hood and larger grille more reminiscent of the larger Buick models, as well as larger taillights. Along with this change came the introduction of an all new electronically controlled 4T60-E automatic transmission to replace the previous 4T60. For 1994, a driver's-side airbag was added, along with standard ABS on all models, standard power windows, and more in the base engine due to a revised intake manifold and cylinder head. The Limited coupe was deleted; only the Custom and Gran Sport (GS) coupes remained. For 1995, another facelift occurred with new smoothed out bumpers, taillights, and body cladding. The interior was completely redesigned to be more streamlined and ergonomically friendly with dual front airbags now standard. For 1996, the larger V6 engine became the 3800 Series II and bumped power to and . All models were now modified to be OBD II compliant. A special "Olympic Gold" edition (also available on Skylark) was added to celebrate Buick's partnership with the 1996 Summer Olympics, complete with gold accents and traditional Olympic logos on the exterior and interior. Production Figures Engines • 1988–1989 Chevrolet LB6 MFI V6, and • 1989–1993 Chevrolet LH0 MFI V6, and • 1994–1996 Chevrolet L82 SFI V6, and • 1990–1995 Buick L27 V6, and • 1996 Buick L36 V6, and == Fourth generation (1997) ==

L L34 I4 (China) }} For the 1997 model year, the Century and Regal once again rode upon the same platform; the revised W platform that was shared with the Oldsmobile Intrigue, the Pontiac Grand Prix, the Chevrolet Lumina and Chevrolet Monte Carlo. The Regal coupe was discontinued. Differences between the Regal and Century were mostly cosmetic. As the upmarket version, the Regal offered larger engines and fancier trim, and once again boasted a newer version of the 3.8 L V6. While the Century was mainly a reliable, economy-minded car based upon the W-body, the Regal was fitted with many amenities, including heated leather seats (optional on the Century), a Monsoon 8-speaker surround sound system, dual climate control, and expansive interior space. Few changes occurred during this version's seven-year run. It offered 5-passenger seating on all trim levels like the Pontiac Grand Prix and Oldsmobile Intrigue (formerly Cutlass Supreme), unlike their predecessors that had optional 6-passenger seating and the Buick Century (formerly built on the A platform) which had standard 6-passenger seating. Buick advertised the Regal GS as "The official car of the supercharged family". Buick also released two other model types, the LSE and the GSE. The LSE stayed with the engine with upgrades and the GSE stayed with the supercharged engine with upgrades. Also, in 2000 Buick came out with a concept GSX that had an intercooled 3.8 L, but was supercharged rather than turbocharged. It had . From 2001 to 2004 Buick offered a Joseph Abboud appearance package on both the GS and LS models. This package included either a solid taupe or two-tone taupe/chestnut leather seats, two-tone leather-wrapped steering wheel, leather shifter handle and boot, 16-inch aluminum wheels; and Joseph Abboud signature emblems on the front doors, floor mats, front-seat headrests, and taillights. The North American Regal was replaced in 2005 by the Buick LaCrosse, also built on the W platform. The final 2004 Buick Regal rolled off the assembly line on June 1, 2004. Engines • 1997–2004 3.8 L L36 Series II V6 • 1997–2004 3.8 L L67 Series II supercharged V6 The Regal LS from the factory had a 1/4 mile (≈400 m) elapsed time (ET) of 15.8 seconds and could do 0-60 mph in under 8 seconds. The supercharged Regal GS had a 1/4 mile ET of 14.9 seconds, and acceleration to took 6.7 seconds. The Regal GS, equipped with the supercharged 3.8 liter V6 engine (L67) produced & of torque. The Regal LS was EPA rated at 19/30 MPG city/freeway while the supercharged Regal GS was EPA rated at 18/27 MPG city/freeway. Regal LSX and GSX (SLP Performance) In the 2003 and 2004 model years, Buick officially offered — in collaboration with Troy, Michigan based tuners, Street Legal Performance, aka SLP Performance — the Buick Regal GSX, with dealer-supplied and installed options for both LS and GS models. The SLP GSX offered three packages, marketed as stages. The Stage 1 package added 10 horsepower with the addition of a dual stainless steel cat-back exhaust system and free-flowing cold air induction system. The Stage 2 package added a Hypertech Power Programmer with an SLP custom calibration — good for an extra 20 horsepower on top of the Stage 1 package. The Stage 3 package added a 3.5-inch smaller diameter supercharger pulley to increase the boost. 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. China General Motors and Shanghai Automotive Industry Corporation (SAIC) established a joint venture in 1997 called Shanghai GM, and had begun assembling the Buick Regal in Shanghai, China in April 1999. The Regal has sold well in the Chinese market as a large, relatively luxurious model, despite its high price, costing more than the North American version. The Chinese market Regal has different front- and rear-end styling compared to the North American version and different engines, including the 2.0 L L34, the 2.5 L LB8 V6 and the 3.0 L LW9 V6. Gearbox choices were a 4-speed automatic for V6 models, while four-cylinder variants are paired with an exclusive 5-speed manual gearbox. V6 models had a set of black dashboard gauges, while the four-cylinder models had white dashboard gauges. These models also had slightly different names: the entry-level model was the New Century, with more upscale models carrying the GL and GLX names. Later, G and GS models were added. Production for this generation ended in November 2008 in China being replaced by the Opel Insignia-based Regal. The Chinese-built Regal was also sold in the Philippines from 2005 to 2006 as the Chevrolet Lumina, where it replaced the Opel Vectra. The 2.5 V6 was the only engine option. The Chevrolet Lumina was discontinued from the Filipino market in 2006, leaving GM again without a mid-size sedan until the introduction of the eighth generation Chevrolet Malibu in 2013. == Fifth generation (2008) ==

|1.6 L LLU turbo I4 (China) |2.0 L LTD I4 (China) |2.0 L LDK/LHU/LTG turbo I4 |2.4 L LE5/LAF/LEA/LUK I4 }} }} The fifth-generation Buick Regal is a four-door, five-passenger, midsized sedan with a front engine, front-wheel drive layout. According to GM published information, more than 41 percent of Regal buyers in the US came from non-General Motors brands, and more than 60 percent of CXL Turbo buyers were under the age of 55. Development The fifth generation Buick Regal rides on GM's Epsilon II platform and is mostly identical to the Opel Insignia. It first went into production in Rüsselsheim, Germany, in 2008. The Shanghai GM twin of the Insignia was introduced in China as Buick Regal in December, 2008 for the 2009 model year. GM originally planned to sell a modified version of the Opel Insignia in North America as the second generation Saturn Aura, but changed strategy after deciding to discontinue the Saturn brand. The Regal utilizes unibody construction with galvanized steel front fenders, hood, roof and door panels and thermoplastic polyolefin (TPO) bumper covers. Buick's product manager director Roger McCormack stated in a 2010 consumer webchat that a coupé version was under heavy consideration, as well as the possibility for further body styles such as a convertible. A Buick-badged Insignia Sports Tourer was also spied, but the following year a Buick spokesperson declared that there were no plans to sell a Regal wagon. Marketing GM presented the fifth-generation Regal to North American dealers on October 14, 2009, and introduced the Regal to the public in November 2009 at the LA Auto Show. Sales of the Regal began in February 2010. In North America, the Regal is positioned below the larger, more expensive LaCrosse and above the Verano compact sedan which debuted late in the 2011 calendar year. Production Production of the Shanghai GM variant of the Regal began in November 2008 and ended in July 2017. North American production at General Motors of Canada's Oshawa, Ontario, assembly plant was confirmed on November 25, 2009, and production began at Oshawa Car Assembly in February 2011. Trim levels CXL The Regal debuted in North America with a 2.4L DOHC I4 engine rated at and of torque, using a Hydra-Matic 6T45 six-speed automatic transmission. The 2011 Regal manufactured in North America was offered in a single trim level, marketed as CXL, offered with two engine choices and seven option packages. Buick had planned to offer a lower-level trim called CX with cloth seats and a higher level trim called CXS, but those trim levels were not offered. CXL Turbo The CXL Turbo comes equipped with a turbocharged 2.0L direct-injected Ecotec DOHC I4 rated at and of torque, mated to either an Aisin AF40 6-speed automatic or a 6-speed manual transmission, making the Regal Turbo the first Buick model to be offered with a manual transmission since the Buick Skyhawk ended production in 1989. The 2.0L turbo is the first direct-injected turbocharged production car capable of running on any blend of gasoline or E85 ethanol. GS At the 2010 North American International Auto Show in Detroit, GM showed a concept GS version of the Regal based on the Opel Insignia OPC and the Vauxhall Insignia VXR. The concept featured a 2.0L, , high-output DOHC I4 turbocharged Ecotec engine, a 6-speed manual transmission and all-wheel drive. The production GS left most of the concept specifications intact, but is front-wheel drive. The GS features Buick's Interactive Drive Control System with GS mode, a choice of an FGP Germany F40-6 six-speed manual or Aisin AF-40 (G2) six-speed automatic transmission, high performance brakes with Brembo front calipers and high performance strut (HiPerStrut) front suspension. 19 inch wheels were offered standard, with 20 inch forged aluminum wheels available as an option. The production version is equipped with GS-only high-output version of the Ecotec 2.0L turbo engine with at 5300 rpm and of torque at 2400 rpm. The GM LHU engine used in the GS trim makes 135 hp per liter - Buick's highest specific output ever. The GS has a quoted 0 to 60 mph (97 km/h) time of 6.7 seconds (Motor Trend achieved 6.3 seconds) and a quarter mile time of 14.9 seconds. The GS went on sale in fall 2011 as a 2012 model. Shanghai GM's locally produced variant of the Regal GS went on sale in China on September 15, 2011. The output of the 2.0L Turbo SIDI engine is , which is about less than the production US-model. The torque is . and the top speed is claimed as . The car is only offered in this case as a front-wheel-drive. There exist also some interior and exterior differences between the American and Chinese models. Sport Touring Edition For 2016, the Regal added a new Sport Touring Edition which included unique 18-inch aluminum black pocket wheels and a rear lip spoiler. This remained in the lineup for this generation's final model year. eAssist hybrid system Beginning in 2011, Buick began offering the eAssist system in the Regal, The 2012 model year Regal is the second GM vehicle to offer eAssist after the 2012 Buick LaCrosse. The eAssist system is standard in the LaCrosse 2.5 L I4, but the eAssist powertrain is optional in the Regal. The eAssist system adds a lithium-ion battery housed in the trunk, along with regenerative braking, engine stop/start, fuel cut-off, grille louvres that close at speed, underbody panels and low-rolling resistance tires. The eAssist system adds up to to the standard 2.4L Ecotec engine during acceleration. Fuel economy for the Regal with eAssist is estimated at city, highway. 2014 update GM presented an updated 2014 Regal at the 2013 New York Auto Show. Changes included a revised interior and exterior, an increase to 258 hp (192 kW) and 295 lb·ft (400 N·m) of torque for the CXL Turbo and an available all-wheel drive option for the 2.0L engine/6-speed automatic transmission equipped vehicles. Changes for the GS included revised interior and exterior, a drop in power to match that of the CXL Turbo, and available an all-wheel-drive option offered for the 2.0L / six-speed automatic transmission equipped vehicles. The six-speed manual transmission was offered in the front-wheel-drive variant. Buick's VentiPorts reappeared starting with 2014 models, a styling feature first used by Buick in 1949. For model year 2014, safety features included forward collision warning, lane-departure warning, blind-spot monitoring, rear cross-traffic alert, and a following-distance indicator. The foregoing are all part of a Driver Confidence package, while collision preparation, which pre-loads the brake system ahead of an imminent collision, and adaptive cruise control are available separately. == Sixth generation (2018) ==

}} }} }} }} }} }} On April 4, 2017, GM presented the sixth-generation 2018 Buick Regal at the GM Design Dome in Warren, Michigan; 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 250 hp 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).

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 Subaru Outback 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 Enclave). Buick offered the TourX with three trims: 1SV (base), Preferred, and Essence (the Avenir and GS were not offered) Fitted with the 250 hp LTG turbocharged I4 ( of torque), the TourX only used an 8-speed automatic transmission. Turbocharged Regals were fitted with a 9-speed automatic transmissions while the hybrid was fitted with a CVT. 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. 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 sport utility vehicles (SUVs). Alongside shifting consumer tastes, the discontinuation of the Regal in North America was also influenced by the sale of Opel and Vauxhall to PSA Group. While the latter did not operate in North America in 2017, at the end of 2019, PSA Group acquired FCA, which created Stellantis (the current parent company of Chrysler in North America). In China, SAIC-GM continues to produce the Opel-designed Regal sedan, slotted between the Verano and LaCrosse sedans; the standard Regal and Regal GS underwent a model update for 2021. == Sales ==
