1972 Buick LeSabre

The Le Sabre name was used by Buick in 1951 for a show car that showcased aircraft-inspired design elements that included tail fins and a wraparound windshield. In 1959, the LeSabre name was used as a replacement for the Special as Buick's entry-level model. By 1971, the LeSabre had entered its fourth generation of styling, and like other General Motors divisions, the entire Buick B- and C-body cars were given a new and modern appearance. While the late 1960s had witnessed the rise of muscle cars, the 1970s ushered in new trends toward safety, fuel economy, and luxury. To that end, the LeSabre bodies were given a double shell roof for improved roll-over protection, and a MaxTrac computerized traction control system became optional. Engines were revised to meet the 1972 federal and California emission standards, with SAE net figures based on an engine as installed in an automobile with emission controls and accessories hooked up, instead of the gross horsepower method used in past years based upon a dynamometer rating from an engine not installed in a vehicle. Engines received EGR valves, which would be installed on engines of virtually all automobiles for nationwide sales in 1973. A new 'FASTEN SEAT BELTS' light and larger federally mandated '5 mph' front bumper became standard during the early 1970s. The hoods grew longer, the bodysides became more curved, and the glass area became more expansive. The new top design on convertible body styles allowed for a full-width rear seat and two-door hardtop coupes had semi-fastback rooflines.

The 350 and 455 cubic-inch V8 engines were carried over from 1970 but the compression ratios were lowered, along with various other modifications, to better utilize the lower-octane low-lead or unleaded gasoline as a result of a General Motors corporate mandate. Power front disc brakes and variable-ratio power steering became standard on all LeSabres in 1971. Shortly after production began, the Turbo Hydra-Matic became standard, a feature that would remain with the LeSabre until its final year in 2005.

Styling changes on the 1972 Buick LeSabre included a small 'Buick' nameplate position above the right side taillight, replacing the prior larger block letters spelling 'B U I C K' across the lower trunk lid between the taillights. The front received a revised grille positioned above a one-year-only 2 1/2 mph front bumper. All of GM's large body cars, including the B-, C- and E-body, were given the 2.5-mph bumper for 1972. There were no deck louvers for the Full-Flo ventilation this year, and a trio of ventiports continued to reside on the front fenders.

G.M. had introduced the flow-through ventilation system in 1971 which used vents mounted in the trunk lid. This system was used by full-sized GM cars and the compact Chevrolet Vega. The system used the heater fan to funnel air into the car from the cowl intake and channel it through vents in the tailgate or trunk lid. The system was designed to send fresh air to passengers when the car was stopped or moving slowly. While the designs were sound, the real-world application of the system did not work. Within weeks of its 1971 debut, the system was found to pull cold air into the car before the heater could warm-up, and it was unable to be turned off. Extensive modifications were made for the 1972 system, resolving these issues.

All controls and instrumentation were within the reach of the driver thanks to the wrap-around cockpit-style instruction introduced in 1971. The seats were built from a new full-foam design with headrests more squared off than its 1970 siblings.

Trim levels continued to be the base and Custom with body styles that included a sport coupe, hardtop sedan, and a sedan. A convertible was exclusive to the Custom line, and all Custom models had a broader lower body molding, bright wheelhouse moldings, Custom plaques beneath the LeSabre signatures on the front fenders, and a plusher interior of all-vinyl or fabric and vinyl.

Standard equipment on 1971 base and Custom LeSabre models included variable-ratio power steering and power front disc brakes. The sedan had a factory base price of $3,960, the sport coupe listed for $4,025, and the hardtop sedan at $4,080. The Custom trim level added approximately $80 to the base price. The convertible sold for $4,300.

The standard engine was a 350 cubic-inch V8 with hydraulic valve lifters, five main bearings, a Rochester two-barrel carburetor, and delivering 230 horsepower at 4,200 RPM.

A total of 183,312 examples of the LeSabre were built in 1972 accounting for approximately 27-percent of Buick's total production. A total of 58,666 base LeSabre models were built and 124,646 of the Custom. The convertible was the most exclusive body style with 2,037 built. 50,804 were Custom hardtop Sedans, 36,510 were Custom Sport Coupes, and 35,295 were Custom Sedans.

This fourth generation of styling on the LeSabre would continue through 1976. In 1977, the LeSabre and other GM B-body full-sized cars became shorter, lighter, and smaller on the outside. G.M. had begun a 'corporate-wide' downsizing of all its vehicles in efforts to improve fuel economy ratings due to the energy crisis of 1973 and 1974.

The LeSabre was discontinued at the close of the 2005 model year and was replaced in 2006 by the Lucerne. Prior to its demise, the LeSabre had been America's best-selling full-size car. The last LeSabre rolled off the Lake Orion, Michigan assembly line on June 18, 2004.

With over half a century's worth of memories, the earlier models of the LeSabre inspire a sense of nostalgia back to a time when life was supposed to be simplified. The image of technology in the early stages, design, dynamic lines, unique and individual accessories, and the advanced exterior engineering is apparent in the LeSabre models of old. Maintaining the same qualities that carried it through the rough times, superb engine, tremendous engineering, and unwavering reliability, the LeSabre continues to impress car enthusiasts today.

Buick has kept an age-old reputation for producing 'the best of the best', and the LeSabre has proved capable of weathering the storms of the times and acclimating itself to the ever-changing demands of its clientele. With parts available in a various and wide array, the option to upgrade the Buick LeSabre is simplified and all-encompassing.

A concept vehicle created originally by General Motors Styling and Buick Engineering, the LeSabre was finally revealed in 1951. Eight years later, the LeSabre nameplate was finally put on a production vehicle. Perhaps not as exhilarating as the 1951 dream car, the styling on the 1959 vehicle with its large tail fins was both dynamic and a sign of the times. A mainstay at Buick for four decades, the total sales of the LeSabre model exceeded six million. The LeSabre has been the number-one-selling full-size vehicle in the U.S. and has won both numerous quality and 'best buy' awards for the past six years.

Totally redesigned for the 2000 model year, the LeSabre sported a fresh view and design as well as various innovative safety features, comfort, and convenience.

Consistently ranked as Buick's best-selling full-size car, the LeSabre was Buick's entry-level vehicle. Replacing the full-size Buick Special model in 1959, LeSabre has also carried the title of America's Best-Selling Full-size Car until its discontinuation at the end of the 2005 model year. The vehicle was replaced by the 2006 Buick Lucerne. The LeSabre nameplate has outlasted the Electra, Electra 225, and the Invicta. The LeSabre also carried the lowest base price in the Buick lineup. A full-size car was produced by the Buick division of General Motors, the Buick LeSabre replaced the full-size Buick Special model in 1959.

Originally showcased on a Motorama show car in 1951, the LeSabre nameplate was featured in various line of body styles. Though during 1965 through 1975, the station wagon variant was dropped from Buick's full-size line, the LeSabre has been offered in a full line of body styles. The pillared coupe eventually became the only model available, both sedan and wagon body styles, in 1977 the LeSabre along with other GM full-size models were downsized. Beginning in 1964, all LeSabre models except the Estate Wagon shared their drivetrains with the mid-size Buick models.

Available in two trim levels, the LeSabre Custom and the base model from the start in 1965, the Estate Wagon model was dropped. Dropped in 1970, the LeSabre 400 package included a '400' 3-speed automatic transmission along with a 4 barrel carburation on its small V8 engine. The 3-speed THM 350 transmission became standard on all models. Replacing the base Wildcat model from the year before, the new LeSabre Custom 455 now shared its model number with the Wildcat.

The LeSabre convertible model was dropped in 1973. The following year the LeSabre Luxus, a much more luxurious model, replaced the Centurion model. Available with a new 'performance package', the Luxus included a 455 cubic inch engine, suspension upgrades, and other various equipment. After a year off the market, the convertible coupe model returned to the LeSabre lineup, and the Stage 1 performance package became available on the LeSabre in 1974.

One of the largest vehicles to be powered by a V6 engine, the 1976 Buick was the first American full-size car with a standard V6 engine. The LeSabre Sport Coupe came with a turbocharged V6 with a 4 barrel carburetor in standard equipment from 1978 to 1980. The LeSabre Limited replaced the LeSabre Custom model in 1979. Bucket seats with a center console also became available on the Sport Coupe model. In 1980, the 'portholes' which had showcased on all LeSabre models since 1960 were removed.

Introduced on the new front-wheel drive H platform, the 1986 Buick LeSabre departed from the rear-wheel-drive on the GM B platform. With only minor updates through the years, the LeSabre station wagon, later called the Estate wagon, remained based on the B platform before being discontinued in 1990. A Grand National model was released in 1986, eventually followed by the LeSabre T/Type in 1987 through 1989.

Used throughout the 1980's as a performance package by Buick was the T-type designation. From 87 to 89, the LeSabre T-type was a representation of the highest performing H-body. A notch above other LeSabres, the T-Type's direct competition was the outstanding Regal. Originally, the T-Type was seemed to need a Turbo, the engine output was limited due to transmission durability complications. Instead, Buick chose to improve the acceleration by utilizing a performance axle that was geared lower than most LeSabres. Grand National inspired black-out trim, and the addition of aluminum wheels and both front and rear spoilers improved the vehicle styling. The installation of a console with shift lever and front bucket seats updated and improved the interior. To accent the T-type badges, a Pontiac-style red-orange dash cluster was used, as well as other interior changes. By installing a large 1.25-inch sway bar in the front, and a .75-inch bar in the rear, the handling was greatly improved. Agile, while still incredibly comfortable, the T-type was an amazing vehicle that was beautiful without being flashy.

Redesigned with a fresh image in 1992, the Buick LeSabre now joined the ranks of the new Regal, Century, and Park Avenue Sedans. Available only as a four-door sedan, the LeSabre continued this style until being discontinued in 2005. Featuring GM's plastic body technologies, the high-strength plastic now replaced the front fenders, and the headlight were streamlined with a separated amber turn signal strip that wrapped around the lower front fascia. The front was smoothed with simplified chrome molding and absent bumperettes while the rear fascia featured a wider trunk mouth and lower liftover height to ease loading baggage.

Producing 170 hp in 1992, the LeSabre has had the same engine, the 3800 V6, and is capable of 18 mpg in the city, and 28 mpg on the highway. The LeSabre accelerated to 60 mph in 8.9 seconds and had a top speed of 107 mph.

Offered in two trim levels, the base Custom trim and the premium Limited which featured allow wheels, fold-down access panels to access the trunk from the rear seat, and the hood ornament. The Limited also had an 18-gallon fuel tank, power radio antenna, anti-lock brakes, and many high-tech instrumentation features.

The LeSabre standard 3800 series V6 OHV powerplant received an extra 35 hp in 1995, due to an intake manifold and re-engineered throttle body. Rated at 19 mph in the city, and 29 mph on the highway, the engine on the 3800 series even received better fuel economy.

Introduced in 1999 as the Buick LeSabre 2000 on the G-body, the automobiles eventually reverted to the Buick LeSabre nameplate following the end of the 2000 model year. On an updated revision of the G platform that was also shared with the 2001 Oldsmobile Aurora and the Pontiac Bonneville, the LeSabre was manufactured in Hamtramck, Michigan at GM's Detroit/Hamtramck Assembly factory. Various changes were made that included a grille that did not open with the hood, smaller overall dimensions, a slightly larger interior area, and due to a new chassis; an overall stiffer structure.

The previous Custom and Limited trim levels from 2000 were carried into 2003 models. To commemorate Buick's Centennial, a new Celebration Edition package was featured on all of the standard equipment of the Limited. Buyers were able to choose from a blacked-out grille, pearlescent White Diamond or Crimson Pearl tri-coat paint schemes, 16' chrome wheels, and special badging. Available features that were either optional or standard on the LeSabre included OnStar, EyeCue heads-up display, Stabilitrak, all-weather traction control, side airbags, automatic load-leveling, heated seats, tire-pressure monitoring system, dual-zone climate control, and RainSense automatic windshield wipers.

The final LeSabre was rolled of the Lake Orion, Michigan assembly line on June 18, 2004.
