The Buick Regal is a car manufactured by the Buick division of General Motors from 1973 through 2004 and again since 2011. It debuted as a personal luxury car for its first six years and then was later overhauled as a more conventional midsize car available in coupe and sedan versions for the majority of its production - but sedan only since 2011. In general, the Regal's design and engineering places a greater emphasis on a sport-oriented ride and experience than most other Buick's - especially true for the current GS model. Throughout the history of the Regal, five generations of cars have been built, showcasing many of the changes in automobile technologies in the more than five decades of its existence.


The Personal Luxury Era (1973 to 1977)

The Regal served as one of GM's very first personal luxury cars. Cars like this were specifically designed to meet the needs of the driver, offering most amenities and creature comforts behind the wheel, leaving the rest of the interior to be somewhat plain. This emphasis on both control and simplicity was very popular during this time - and stayed in focus until about 2002.

The model itself was built on GM's A-body in a RWD/Longitudinal Layout. The Regal had a choice of three powertrains: 231 cubic inch V6, 350 cubic inch V8, 455 cubic inch V8

The V6 engine made its way into the market in 1975 and was a predecessor to GM's very popular 3800 Series. The introduction of this option can be seen as an early response to the rising gas prices after 1973. The Regal was notably amongst the first midsized cars equipped with a V6 engine, a momentous change in a class of automobiles that typically carried V8 engines. Soon after the American automotive industry, as a whole, would engage in major V6 powerplant production.


Downsizing (1978-1987)

The Regal was trimmed down for 1978 and its 231 cubic inch V6 was reduced to a 3.2 liters at 196 cubic inches for the lighter weight Regal. A 3.8-liter turbocharged V6 gave the Regal an unexpected reputation for performance. The Turbo Regal included a firmer handling suspension with larger tires and aggressive looking wheels. The only other cars available in America with turbocharged engines in 1978 were from Mercedes-Benz, Saab and Porsche.

In 1981 a major facelift gave the Regal a much more aerodynamic profile. This change made it possible for the car to compete on the NASCAR racing circuit. In 1981 and 1982 the Regal won the manufactures title. V8s were still available but had shrunk to 4.3 liters at 265 cubic inches. The 5.0 liter 307 cubic inch v8 was available as an option in 1986 and 1987 but the 3.8 liter 2 barrel V6 was standard. The 2004R transmission with overdrive was an option available with either engine.

Buick Regal Grand National Coupe
The 1982 Grand National came with a naturally aspirated 4.1 liter V6 engine with 125 horsepower at 4000 rpm and 205 foot pounds of torque at 2000 rpm. There were 215 Regal Grand Nationals produced in 1982 and approximately 35 were based on the Regal Sport Coupe package with the turbocharged 3.8 liter V6 engine with 175 horsepower at 4000 rpm and 275 foot pounds of torque at 2600 rpm. Our of 2,022 Sport Coupes produced in 1982 it is estimated that less than 50 came with both the Grand National and Sport Coupe packages.

There was no Grand National in 1983. The Sport Coupe model was renamed T-Type and 3732 were produced. They had 190 horsepower at 1600 rpm and 280 foot pounds of torque at 2400 rpm.

The Grand National returned in 1984 and was only available in black. The 3.8 liter turbocharged V6 was now standard and had been refined with sequential fuel injection, distributor-less computer controlled ignition and had 200 horsepower at 4400 rpm with 300 foot pounds of torque at 2400 rpm. Only 2,000 of 5,204 Turbo Regals produced in 1984 were Grand Nationals. The Quarter mile was achieved in 15.9 seconds at stock boost levels of 10 psi, while for the same year, the Camaro was 1 second slower and the Corvette 1 second faster.

In 1986, there were only 7,896 Turbo Regals produced.

There were 27,590 Turbo Regals produced in 1987. This was the peak of popularity and oddly enough the final year. Toward the end of the production run between September and December - Grand Nationals were considered "1987 1/2" model years. A WE4 lightweight version was available along with the GNX, which was created to be the "Grand National to end all Grand Nationals". The GNX was claimed to be the fastest production sedan ever built at the time. A modified engine design with intercooling boosted the performance even further to 245 horsepower and 355 foot pounds of torque. Buick dropped the T-Type package for Regal at this time. In 1987 the rear wheel drive Regal, reaching the end of its long production run, was still a popular Buick. It was available in Regal, Regal Limited and Regal Grand National form.


Front-Wheel Drive Era (1988-1996)

1990 Buick Regal Limited Coupe
In 1988 a new front-wheel drive Regal was introduced on the GM W platform. It had no serious performance option with only a 2.8L V6 producing 125 horsepower. There was no V8 engine and the V6 no longer offered a turbocharger. It was offered as a coupe only until 1990 when a 4-door sedan was introduced.

In 1989, the Gran Sport trim line was introduced, featuring aluminum wheels, body side cladding and a console mounted shifter attached to a 4-speed automatic.

In 1990, the Regal gained the option of the Buick 3.8 V6. The 3800 V6 was unique to the Regal.

In 1994, the Limited coupe was dropped from the lineup.

In 1996, the last year for this model, 35 horsepower was added and only the Custom and Gran Sport coupes remained.


The Fourth Generation (1997-2008)

The engines available for this generation were the 3.8 liter L36 Series II V6 and 3.8 liter L67 Series II supercharged V6. The Regal LS had a 1/4 mile time of 15.8 seconds and could do 0-60 mph in under 8 seconds from the factory. The supercharged Regal GS had a 1/4 mile ET of 14.9 seconds and reached 60 miles per hour in 6.7 seconds. The Regal GS, equipped with the supercharged 3.8 liter V6 engine (L67) produced 240 horsepower and 280 foot pounds of torque. The Regal GS's PCM had programming which activated torque management to reduce wheel spin at launch to help avoid "fish nosing". The Regal LS was EPA rated at 19/30 miles per gallon city/highway while the supercharged Regal GS was EPA rated at 18/27 miles per gallon city/highway.


The Fifth Generation (2009-Present)

The Buick Regal enter it's fifth generation as a four-door, five-passenger, midsize front wheel drive sedan. General Motors designed the new Regal to attract new, younger customers to the brand. More than 41% of Regal buyers in the US are conquest sales coming from non-General Motors brands, and over 60% of purchasers of the CXL Turbo are under 55 years of age.

This new Buick Regal is essentially the same car as the Opel Insignia. GM originally planned to sell this car as the second generation Saturn Aura but felt Buick would be the best fit after the Saturn brand was cancelled. It's available in CXL, CXL Turbo, GS and eAssist form.

In 2014 the Buick Regal underwent a mid-cycle refresh which included updates to both the interior and and exterior, a bump in performance for the CXL Turbo bringing it to 258 horsepower and 295 foot pounds of torque, and an available all-wheel drive option offered for vehicles equipped with the 2.0L and six-speed automatic transmission. Changes for the GS would also be an updated interior and exterior, some loss of power to match the CXL Turbo and available all-wheel drive option for vehicles equipped with the 2.0 liter six-speed automatic transmission. The six-speed manual transmission was still available but only as an option in the front-wheel drive version. Starting with 2014 models, Buick's traditional VentiPorts, which date back to 1949, have reappeared.

Forward collision warning, rear cross-traffic alert, blind-spot monitoring, lane-departure warning, and a following-distance indicator were several new safety features added for 2014. These are all part of a package named "Driver Confidence". Two other options: 1. collision preparation, which pre-loads the brake system ahead of an imminent collision, and 2. adaptive cruise control - are available separately.
