The Buick LeSabre is a full-size car made by General Motors from 1959 to 2005. Before 1959, this position was maintained by the full-size Buick Special model (1936-58).
The name is derived from 1951 GM Le Saber designed by Harley Earl; the car was often mistakenly associated with the Buick division but actually it was presented as a GM vehicle without reference to a particular GM division. Buick closely related their 1956-1957 models to GM LeSabre by replicating the top of the rear wing into their design.
The word LeSabre is French for saber.

Sejarah model
The LeSabre board made its first appearance in the 1951 Le Louz exhibition car, which introduced the world to design elements inspired by aircraft such as windshields and tail fins. There is a V12 for Buick LeSabre (5.00L) originating from 1953. In 1959 LeSabre became the new moniker for what was formerly known as Buick Special. The Buick LeSabre is offered in a full line of body styles except between 1965-1969 when the station wagon variant is dropped from the Buick full size offer. In 1977, LeSabre downsized along with other GM full-size models, and is only available in coupe models, sedans and pillared carts.
In addition to being a Buick entry-level vehicle, LeSabre consistently sells Buick full-size cars. Of the four nameplates introduced in 1959 (LeSabre, Invicta, Electra, Electra 225), the LeSabre name plates lasted the longest.
From 1959 to 1961, LeSabre was supported by a 364 cubic inch V8, which was smaller than the 401 cubic inches V8 used in the more expensive Invicta and Electra models. The 364, previously used in all Buicks in 1957 and 1958, rated at 250 horsepower (190 kW) in standard form with an "economic" 235 horsepower (175 kW) version offered as a "no-cost" option in the 1960s - 61 and an optional power pack version with a four-barrel carburettor and dual exhaust rated at 300 horsepower (220 kW). For 1962-63, LeSabre came standard with a two-barrel carburetor version of the 401 V8 rated at 280 horsepower (210 kW), or at no cost "economy" low-compression version rated at 260 horsepower (190 kW). Beginning in 1964, all LeSabre models except the Estate Wagon share their drivetrains with medium Buick models by switching to smaller V8-displacement models at least as standard equipment for the next few years with a cubic displacement of 300 inches (1964-65). ), 340 (1966-67) and 350 (1968-76). A large displacement will not reappear in LeSabre until 1970 when 455 cubic inches V8 was introduced as an option and offered until 1976. Started with a reduced and progressive 1977 model through the next three generations of LeSabres introduced in 1986. 1992 and 2000, Buick's 3.8-liter (231 cubic inches) V6 will be the standard engine for most LeSabre models and the V8 engine is dropped (except at the station wagon) after the last of the LeSabre rear-drive sedan and the coupe came off the line in 1985.
For most of 1959-1971, the three-speed manual transmission was standard equipment on all LeSabres but rarely ordered. Much more popular is the Turbine Drives automatic transmission (formerly known as Dynaflow) along with power steering and brake power. For 1961 and 1962, automatic transmission was standard on LeSabre and all other full-sized Buick but in 1963 moved back to the option list on LeSabres. For 1964, the Dynaflow-based Turbine Drive was replaced by two new automatic transmissions, a two-speed Super Turbine 300 and a 400-speed Super Turbine. The four-speed manual transmission was offered as a LeSabre option from 1963 to 1965 but only a small number of cars were equipped. The automatic transmission will again reappear as standard equipment at LeSabres in mid 1971 and continue in such form until the disappearance of the model line after 2005.
LeSabres was a six-passenger vehicle from 1959 to 1985 (station wagon up to 1990) featuring a separate body-on-frame construction along with an elongated front engine mounted. The first generation of the minimized LeSabres introduced in 1977 retained rear-drive and body-on-frame construction, while the generation model introduced in 1986 switched to front-wheel-drive, unit-mounted construction and transverse-mounted engines. Convertibility was offered every year until 1975 while hardtop two and four doors were dropped after 1976 and only pillared body styles were offered from 1977 to 2005. The train station was offered in 1964 and then dropped for several years until it was reintroduced in 1970 and continued into 1990 after which year they were transferred to the revived Roadmaster series. LeSabres comes in two versions: Custom and Limited.
Maps Buick LeSabre
First generation (1959-1960)
1959
LeSabre and other 1959 Buicks not only have new names, but also new styling, adopt the new GM B- and C-body used on all corporate full-sized cars (the larger C-body used in Electra and Oldsmobile 98 and all Cadillacs on essentially a stretched B-body, not a different body and chassis for 1959-60). Wheelbase increases by one inch on all models. The new styling includes a tilted headlight on the front along with a kromy square grille somewhat similar to a 1958 Buick and "Delta-wing" flip back along with a round rear light. The appearance was shared with two other Buick models, the mid-level Invicta and the top models of the Electra.
While the Invicta and Electra/225 models are powered by the new Buick 401-cubic inch V8, LeSabre is continued with a 364-cubic-inch V8 previously used in all Buick in 1957 and 1958. In standard form, the engine delivered 250 horsepower with carburetors two-barrel and 10.25 to 1 compression ratio (with Dynaflow transmission; the manual transmission car has a compression ratio of 8.5 to 1 lower but horsepower is still rated at 250). The optional available is a four barrel version of the 364 that is rated at 300 horsepower. The three-speed manual transmission is standard on LeSabre but most cars are built with the optional two-speed Dynaflow automatic transmission which is standard equipment on Invicta and Electra/225. A three-speed Dynaflow Triple Turbine variant is also available. Power steering and power brakes are optional and all 1959 Buicks use a unique 12-inch finned brake drum brake to enhance the stopping power initially introduced on the 1957 Roadmaster.
1960
The 1960 LeSabre received a great facelift, the new body design just sharing the roof and trunk lid with the 1959 model. The new buick now wears a concave grille and horizontal headlights centered by Buick's "Tri-Shield" logo, still in use today. Reintroduced to Electras and other Buick for 1960 is the "VentiPort" chrome porthole which was first introduced in 1940 and last seen in 1957. The LeSabre and Invicta models have three peepholes while Electras and Electra 225 are "four-hole".
Inside, the revised instrument panel featured a "Mirromatic" speedometer that the lenses could be adjusted for better visibility to fit the driver. A new two-spoke steering wheel with a horn beam was introduced, replacing a time-honored horn ring that is still common to most cars. The 364-cubic-inch 250- and 300-horsepower V8s resumed from 1959, but the new cost-free option was a 235-horsepower two-barrel compression version of the 364 with a lower compression ratio to allow for regular use of class gas instead of materials premium fuel is required with all other Buick engines.
Generasi kedua (1961-1964)
1961
LeSabre and all other full-size Buick (joining the Special compact this year) were completely restored for 1961 featuring endless rear ends, more controlled chrome usage, and sheetmetal boxier. Wheel spacings remain at 123 inches (3,100 mm) but the new cars are slightly downsized both in length and width, and are riding on a new X-frame chassis that includes conventional rear axles and driveshaft replacing the decade-long torque tube design.
Inside is a revised instrument panel that maintains a "Mirrormatic" speedometer and new trim upholstery. The Station Wagons accept all-vinyl interior as standard, with the usual combination of fabric/vinyl available as an option.
The engine has not changed from previous years including the standard 364-cubic-inch V8 364-horsepower engine, without the usual 235-horsepower 364 fuel cost or the 300-horsepower four-barrel option from the same machine available at an additional cost. Two-speed automatic transmission Turbine Drive Dynaflow is standard equipment on LeSabres and all full-size Buick this year, although manual transmission is also available.
1962
The 1962 Buick LeSabre just changed slightly from the previous year with the body taking a few extra inches to give them a longer look along with new grille and taillights. Two two-door hardtop coupe receives a new convertible roof line complete with a simulated bow.
Under the hood, 364 cubic inches V8 was replaced by a larger 401 cubic inch V8 used in Invictas and Electra 225s. LeSabres comes standard with a high-compression two-barrel version (10.25-1) rated on 280 horsepower with an ordinary low-compression fuel version of the same engine rated at 265 horsepower offered as a no-cost option. Optional at an additional cost is 324 horsepower 404 which is standard on Invicta, Electra 225 and mid-year Wildcat coupe Invicta.
Inside, the interior is slightly revised with a "Mirrormatic" speedometer replaced by a conventional horizontal sweep unit.
1963
The 1963 LeSabre received a large facelift with a flatter body contour than the 1961-62 model and a revised roofline on a four-door hardtop sedan.
Inside there is a new instrument panel with round instruments that are shared with other big Buick and a new deluxe private Riviera coupe. New options this year include steering wheel/seven position slope column, AM/FM radio and Electro-Cruise control.
The same range of the 401-cubic-inch V8 was brought from 1962 but the three-speed manual transmission back as standard equipment with two speed Turbine Drive automatically returned to the options list. This new and rarely ordered option this year is a four-speed manual transmission mounted on the floor.
1964
Minor facelifting with a new grille and horizontal rear light replacing the 1963 vertical unit that highlights LeSabre 1964. The better-equipped "Custom" version also joins the lineup this year, easily identified by chrome-side full length molds with brushed metal inserts. LeSabre used to have small pieces on the back of the three bodies.
Under the hood, a 401-cubic inch V8 is replaced in a LeSabre sedan and coupe by a smaller 300-cubic-inch V8 designed for a replaced Special/Skylark intermediate that replaces the V8 aluminum in the vehicle. In standard form, 300 are rated at 210 horsepower with two barrel carburettors and a compression ratio of 9 to 1 for regular fuel use. Optionally available is a 250-horsepower version of the same engine with a four-barrel carburetor and a comparable 11 to 1 compression ratio that mandates the use of premium fuel. The LeSabre Estate Wagon comes standard with 325-horsepower larger 401 V8 than Wildcat and Electra 225 models.
Replacing two-speed automatic transmission based on the old Dynaflow are two new Super Turbine automatic pistols. The two-speed Super Turbine 300 (shared with midsize car) is available with a standard two-barrel 300 V8 while the three speed Super Turbine 400 (shared with Buick and other large Rivieras) is standard with 300 four barrel and optionally with standard engine as well as 401 at Wagon Estate. The standard transmission with a base of 300 V8 two barrels is a manual three-speed column shift and four-speed manual is available as an option with either engine. The new ST300 transmission was made through a variable tone torque converter from Dynaflow that had been in use since the mid-1950s, while the first year for the ST400 featured a fixed-tone converter.
Inside, only a few revisions of the trim/seats are made.
Third generation (1965-1970)
1965
LeSabre and other full-sized Buick were completely redesigned for the 1965 model, featuring a more rounded body line and a Coke-bottle profile with a semi-fast roof line on a two-door hardtop coupe. Wheel spacing remained at 123 inches (3,100 mm), but the new perimeter frame that was shared with other GM B-body cars replaced the "X" frame that was used since 1961. Body styles remained unchanged from 1964 except for the station wagon, dropped at support Buick Sport Wagon made from a medium-sized special that stretches featuring an elevated rear roof and skylight glass above the back seat similar to Oldsmobile Vista Cruiser.
Beginning in 1965, LeSabre is available in two trim levels, LeSabre and LeSabre Custom bases, featuring a more luxurious interior trim and also includes a convertible body style that is not available at the LeSabre baseline.
The interior was also new to 1965 with a revised instrument panel featuring two quick rounds almost identical to the Riviera for speedometer and other instruments such as the 1963-64 model along with the new heater/AC control.
Drivetrains unchanged from 1964 with a 250-horsepower two-barrel 300-cubic-inch carburetor V8 standard powerplant on all models with a standard three-speed manual transmission or optional four-speed manual or two-speed Super Turbine 300 automatic. Available at an additional cost with the new "400" LeSabre "400" package is a four-foot, 300-liter V8 300-liter four-barrel with a carburation of four barrels and 10.25 to 1 compression that requires premium fuel, compared to a standard two-barrel engine that uses materials regular fuel.. The 400 package also includes a more popular Super Turbine "400" three-speed automatic transmission and is also found in the Wildcat, Electra 225 and Riviera models that are more expensive than Buick.
The practice of a Buick engine transmission is similar to that of the GM Chevrolet Division, which at the time only offered a two-speed Powerglide automatic with most of its engine offerings in full-sized vehicles, which required buyers who preferred the same three-speed Turbo-Hydramatic. (essentially the same transmission with a different name) to order one of the larger V8 engines. Both Pontiac and Oldsmobile offer Turbo Hydra-Matic on all of their full-sized cars with each engine offer, and the three-speed auto also becomes the norm on big cars from medium-price competitors such as Chrysler Newport and Mercury Monterey, which each offer a transmission TorqueFlite and Cruise-O-Matic.
1966
The new grille and four-segment rear lights highlight the 1966 LeSabre facelift model. Also new is a revised instrument panel with a horizontal sweep speedometer replacing round pod instruments and a new interior door handle. Both the base series and the Custom level are resumed. New standard security features include layered instrument panels, outside the driver's side mirrors and backup lamps.
Under the hood, the 300-cubic-inch V8 is replaced by a larger 340-cubic-inch V8 with 220 horsepower with two barrel carburettors and is available with a standard three-speed manual transmission or optional two-speed automatic, but the four-speed manual is dropped from option list. Ordering the LeSabre 400 option enhances buyers to a 260-horsepower 340 with a four-barrel carburetor and a compression ratio of 10.25 to 1 higher along with three speed Super Turbine 400 automatic found in larger Wildcat, Electra 225 and Riviera engines.
1967
Somewhat more rounded metal sheets and fastback swoopier backline for a two-door hardtop highlights LeSabre 1967 but the inner chassis and body do not change along with the drivetrains. Both LeSabre Basic level and Custom Level are resumed.
New options for 1967 include front disc brakes and an 8-track stereo tape player. Standard drum brakes are enhanced with more cooling fins and dual-master cylinder systems are introduced.
Engine and transmission offerings remain unchanged from 1966.
1968
The 1968 LeSabre received a small facelift including a new grille and taillights along with a hidden windshield wiper. Inside is a revised instrument panel with a square speedometer surrounded by other instruments with small revisions for the basic and custom models.
The new 350-cubic-inch V8 replaces the previous 340. In standard form, the 350 V8 produces 230 horsepower with a two-barrel carburetor and a compression ratio of 9 to 1 and is equipped with a standard three-speed manual transmission or an optional two-speed automatic two-speed Turbo 300. The "LeSabre 400" option package includes a 280-horsepower 350 V8 four-barrel with 10.25 for 1 compression and three-speed Super Turbine 400 automatic transmission. The "Switch-Pitch" torque converter used in conjunction with the Super Turbine automatic transmission is discontinued to support standard torque converters.
1969
The 1969 LeSabre received a new sheetmetal with a more ambiguous styling of the 1965-68 model including a formal roof line on the coupe replacing the semi-fastbacks of previous years. Although the 1969 model is extensively addressed with a new sheetmetal, the 1965 base chassis and inner body structure are maintained, along with a four-door pillared sedan roof line although the ventilation windows are lowered on all models. The wheelbase is fixed at 123 inches (3,100 mm). The interior is slightly revised with minor changes to the instrument panel including the heater/air conditioning controls on the left of the wheel, which is new this year. Headrests, previously optional, are now standard equipment due to federal security mandates. The 1969 LeSabre and other Buick also received a newly installed steering column locking switch (removed from the instrument panel) which also locks the steering when the transmission is in Park. The ignition/locking steering column appeared in all General Motors cars of 1969 one year earlier than a federal mandate that required all cars to be equipped.
Also new is the variable-ratio power steering unit along with a front suspension geometry revision to improve driving and handling under the Buick trade name from Accu-Drive. The steel rail is also built into the door (and rear quarter panels on the coupe and convertible) to improve side impact protection as is the case with all GM-C cars and 1969 car bodies.
Powertrains were unchanged from 1968 with 230-horsepower 350 standard V8 two barrels and were available with a three-speed manual transmission or two Super Turbine 300 automatic speeds while the LeSabre "400" package once again included a 280-horsepower 350 four-barrel engine and three Super Turbine 400 automatic speed.
1970
Only minor detail changes including the revised grille and rear lights were made for LeSabre 1970. This year's new features include a hidden radio antenna that has two cables embedded in the windshield. The wheelbase increases one inch to 124 inches (3,100 mm), which matches direct competitors such as Oldsmobile Delta 88, Mercury Monterey, and Chrysler Newport.
Both basic and custom models are again offered. Engine revised with standard 350 V8 two-barrel enhanced in horsepower from 230 to 260. New options for the 1970's are the usual low-compression fuel versions of 350 four barrels rated at 285 horsepower and premium compressed premium 350 four-barrel V8 worked on reset with horsepower rising to 315 at a compression ratio of 10.25 to 1. Added to the lineup is a new LeSabre 455 line that shares interior and exterior decoration with Custom LeSabre and powered by a new Buick 455 cubic inch V8 with a four barrel carburetor, 10.25 -1 compression and 370 horsepower, which also require premium fuel.
The transmission offer includes a standard three-speed manual with a column shift for an optional two-bar 350 base or three-speed Turbo Hydra-matic 350 automatic, which is standard equipment with two 350 barrel engines. This transmission completely replaces the old two-speed auto that is offered with a smaller base engine in previous years, while the 455 is paired with the Turbo Hydra-matic 400. Buick now joins the other GM divisions in marketing the automatic transmission under the Turbo Hydra-matic name trade than the "Super Turbine" designation used since 1964.
At the beginning of the model year, variable-ratio power steering and electric drum brakes are optional equipment. They were made standard equipment on all LeSabres (and Wildcats) effective January 1, 1970. Powerful disc-powered discs remain an extra-cost option.
For the first time since 1964, Buick offers a full-sized station wagon for 1970 under the nameplate Wagon Estate . Despite using B-body LeSabre, he drove the 215's 127-inch (3,200 mm) C-body Electra cassette chassis. The Estate Wagon comes standard with 455 V8 and interior trims similar to LeSabre Custom and Wildcat.
The GM Platform B 1965-70 is the fourth best-selling car platform in history after the Volkswagen Beetle, Ford Model T and Lada Riva.
Fourth generation (1971-1976)
1971
Like other GM divisions, Buick completely restored its B-and C-body car in 1971. The full-size car appears bigger and heavier than ever and has also happened. The arrangements include curved bodysides, long hoods and wide glass expanses, similar to the full-size Chrysler Corporation car of 1969, but with a lower beltline than a Chrysler product. The semi-fastback roof line is used on a two-door hardtop coupe and the convertible has a new top design to allow the full width of the rear seat.
The same type of 350 and 455 V8 cubic inches is brought upward but displays lower compression ratios and other modifications to allow for the use of lower lead or lower lead gasoline as a result of General Motors' corporate mandate. The power steering and front disc brake variables were standard equipment on all LeSabres at the beginning of the 1971 model year. In March, the Turbo Hydramatic transmission became standard equipment, and all Buick LeSabres will remain equipped in basic form until the last year of the nameplate in the year 2005.
The new body also features a double shell roof for better roll-over protection. Also new to '71 is a flow-through ventilation system utilizing ventilation installed in the trunklid along with other full-sized GM cars and compact Chevrolet Vega. It uses a heating fan to draw air into the car from the cowl intake, and force it out through the vents in the trunk lid or tailgate. Theoretically, passengers can enjoy fresh air even as the car moves slowly or stops, as in heavy traffic. But in practice, it did not work.
However, within weeks of the 1971 model debut, Buick and all other GM dealers received numerous complaints from drivers complaining that the ventilation system pulled cool air into the car before the heater could warm up and could not be turned off. The ventilation system was extensively modified for 1972.
Also new to 1971 is the optional MaxTrac computer traction control system.
Inside is a new cockpit-style instrument panel that covers all controls and instruments within easy driver reach, along with ease of servicability with instruments and switches accessible from the front when the faceplate cover is removed. The chairs of the new full foam design with denser headrests from 1969-70. Again, the LeSabres Custom bases and models are offered in the same sedan and coupe bodystyles while the convertible is a Custom-only offer. The LeSabre 455 model line was dropped for 1971 with a larger engine now offered as an option on a regular basis and a Custom-series model. Customs LeSabre equipped with an optional 455 engine received a "455" badge under the LeSabre name plate on the front fender instead of the "Special" badge normally used.
1972
The revised grille lens and taillights are one of the styling changes for the year 1972. Exit back, the small nameplate "BUICK" is located above the right side rear lights replacing the uppercase letters "BÃ, UÃ, IÃ, CÃ, K" in the section bottom luggage cover between taillights in 1971. Also new for '72 is a 2 1/2-mph front bumper one year only. All B, C, and E body (large) GM cars received such a bumper for '72.
The trim interior received only a slight revision from 1971. A ventilation system flow-through revised ventilation vent at doorjambs replaced the troublesome system used in 1971 with trunklid ventilation.
Both the 350 and 455 V8 were brought from 1971 with the horsepower ratings swapping new net SAE figures based on a car-mounted engine with connected emissions accessories and controls, rather than the gross horsepower method of previous years based on the dynamometer. ratings of engines not installed in vehicles. With that, a standard 350 barrels V8 is rated at 160 net horsepower compared to 230 horsepower in 1971 while the 455 V8 top rated at 250 horsepower net in 1972 compared to 315 in 1971. The engine was also revised to meet 1972 emission standards federal and California with California-bound cars receiving EGR valves, which will be installed on almost all car engines for national sales in 1973.
Inside, the instrument panel displays a new "FASTEN SEAT BELTS" lamp because of the new federal safety rules and a bell that reads when a key is left in the ignition key also sounds when turning on the car to alert the driver and passengers to attach the seat belt.
1973
The federally required federal "5 mph" front bumper and new vertical grille bar highlight LeSabre 1973 along with a revised rear light mounted on a rather large rear bumper. Both the 350 and 455 V8 are revised with an EGR valve used on both federal and California-equipped emissions cars.
The LeSabre Custom conversion fell this year leaving Centurion short-lived as the only Buick ragtop that year as the middle Skylark (replaced by Century for 1973) lost the ragtop completely after 1972 model year. Machine options are largely unchanged.
1974
New grille and taillights along with a 5 mph rear bumper highlight Buick LeSabre 1974. The four-sided sedan and hardtop sedan retain the same roofline as 1973 but the two-door hardtop coupe features a new roofline with the rear side opera window.
Inside, the instrument panel is substantially revised but retains the wrap-around theme. The new (and rarely ordered) option is the "Air Cushion Restraint System" which includes the driver and passenger side airbags along with a unique four-finger steering wheel. This option, also available on Electra 225 and Rivieras as well as Oldsmobiles and Cadillac is full-sized, not very popular and dropped after the 1976 model.
The new integrated belt and belt were introduced this year along with a federal government mandated interlock system that requires right front passengers and drivers to tie their seatbelts to start the vehicle. The interlock was met with great public condemnation that Congress overturned the interlock regulation at the end of 1974 after some early models of 1975 were so equipped, allowing owners of all 1974 and early 1975 models equipped with an interlock system to break it legally.
With the Centurion line being stopped after 1973, LeSabre is now a full-sized B-body Buick car. The LeSabre base continues, but the new LeSabre Luxus series replaces LeSabre Custom and Centurion. Luxus's convertibility also returns the ragtop to the LeSabre line after a year's absence and only the Buick ragtop.
The engine offer was revised for 1974. 350 two barrels remained standard on all models with optional engines including 350 four barrels and 455 four barrels V8, both brought from 1973 with revisions to meet the 1974 emissions standards. New engine options for 1974 included 455 two barrels and " a 455 "Stage 1 performance package that adds dual exhaust, suspension upgrades and other equipment.
New options for 1974 include radial-ply tires, GM High Energy Focus and "low-fuel" warning lights that light up when the fuel tank drops by up to four gallons. This will be the last year for the MaxTrac electronic traction control system as an option.
1975
LeSabre Luxus's upscale marking was dropped and replaced by a Custom LeSabre signboard. 1975 was also the first year of the catalytic converter, and the standard high-energy ignition that was part of the GM Maximum Mileage System at the time of its Introduction in September 1974. 1975 LeSabre was the first to require the use of unleaded gasoline, due to the emergence of catalytic converters. The LeSabre lineup offers coupes and two sedans, while the LeSabre Custom lineup offers coupes, two sedans, and the only convertible in the Buick lineup. 1975 will be the last year for LeSabre Custom Convertible with about 5,300 instances that roll from the assembly line.
The engine offer is reduced to just two: standard 5.7 liter V8 (350 CID) and four barrel or optional 7.5 liter V8 (455 CID) carburettor with four barrels.
The body line in 1975 was somewhat softer than the 1974 model featuring adjoining round headlights and cross-hatch patterned grille that flowed in the front of the car and under the headlights. The turn signal is located on the front bumper. Tri-shield buick hood ornament is standard on Custom Series and optional on base series. Three ventilort holes were moved from the hood to the front fenders. Taillamps is slightly larger than the 74 that covers the back of the car with the backlight placed in the center broken by the number plate. The four-door pillared sedan receives a new small third window to mimic the six-window "Colonnade" style of the GM intermediates while the four-door hardtop sedan has a new operatic window.
Inside, a new flat instrument panel that was shared with Electra and Riviera replaced the cockpit dashboard of previous years and featured a horizontal sweeping speedometer that only ranged 100 mph compared to 120 mph in the previous year and also included kilometer readings. Otherwise, interior decoration only received a slight revision.
Production that could be converted for both LeSabre Custom and Centurion convertibles was not very abundant in 1971 to 1975. The rarest production at the time was Custom LeSabre 1971 with just over 1,800 units built, and the most widely produced was Centurion 1973 with a little more of 5,700 units built. Due to this very low volume of production and the end of a full-size convertible era, this can make the LeSabre Custom and Centurion Convertibles ragtop quite recoilable - depending on the overall condition of the vehicle. The convertible mechanism used is called the 'scissor top' which is folded in on itself, not straight back. It was featured on all GM full-size convertibles from 1971 to 1976.
1976
Only minor style changes highlighted the 1976 Buick LeSabre, which was the last year for bodyshell in 1971, driver and passenger options on unpopular and rarely-ordered passenger airbags, the 455 V8 and hardtop bodystyles. Changes of quad-square headlights, bakcrate grille, and turn signal located just below the headlights.
The '76 LeSabre is the only full-size American car with a standard V6 engine, which is a new 3.8-liter V6 (231 CID) Buick engine. The V6 is only offered at ground level LeSabre and was not mentioned at the beginning of the 1976 Buick literature released in September 1975 because the V6 engine was a last-minute addition. The 350-cubic inch V8 is the base engine on the LeSabre Custom and the 455-cubic inch V8 is optional. Both V8 are optional on the LeSabre basis.
Fifth generation (1977-1985)
1977
The 1977 Buick LeSabre and other GM B-body full-sized cars are much smaller and lighter than their predecessors with a 700-800 pound weight loss track and an overall length of 10 to 15 inches (380 mm). The large cars were the beginning of downsizing the entire "company" of vehicles in order to improve the fuel economy rankings after the 1973-74 energy crisis that would filter into intermediates in 1978, private luxury cars in 1979 and compacts in 1980 with the subsequent downsizing of each line of vehicles scheduled in subsequent years.
Although the '77 Buick LeSabre is much smaller on the outside, headroom, leg room on the rear seats and luggage space rises above the much larger 1976 model. The machine line consists of a variety of engines including the Buick-built V6 231-cubic inch standard and an array of optional power plants including a 301 cubic-inch V8 Pontiac-build, 350 cubic inches V8 built by Buick and Oldsmobile, and Oldsmobile. 403 cubic inches V8. V6 is standard in base and Custom coupe and sedan, 301 V8 on the new LeSabre Sport Coupe and 350 V8 in Estate Wagon.

1978
Following the downsizing and redesign, in 1978 Buick LeSabre received only minor changes including a new grill job. The engine offerings have not changed from 1977 on most models, but the LeSabre Sport Coupe is now powered by a 231 cubic inch turbocharged V6 engine with a four-barrel carburetor.
1979
Only minor changes include the new grille and rear light taillights that highlight LeSabre 1979 aside from the top-level LeSabre Custom from the previous year renamed LeSabre Limited. The LeSabre Sport Coupe is continued with a turbocharged V6 as standard equipment and a new option for this model is only the Strato seatrest with the center console. This will be the last year for Pontiac 301 and Oldsmobile 403 V8s in the options list.
1980
New metal sheets highlighted by new swept grilles/headlamps, new taillights and revised coupe roof lines were one of the changes to Buick LeSabre in 1980, despite the complete loss of traditional Buick holes (the C-Electra body will defend it until 1984). The cars were also slightly lighter to boost the fuel economy along with slightly more aerodynamic metal sheets that made the 1980 model look a bit larger than their counterparts in 1977-79 but the overall dimensions changed very little.
The bidding machine was shuffled a bit for 1980 with the Buick 231 V6 standard and an optional 350 V8 brought from 1979, with Buick 350 making his final appearance of the year. New options include Buick-built 252 V6 larger, Oldsmobile-built 307 V8 and 350 Diesel V8, also built by Oldsmobile. Coupe Sport LeSabre continues with a turbocharged 231 V6 four barrel as standard and only available powerplant. The Sport Coupe was dropped from the line after 1980 along with the Turbo V6 engine due to slow sales, with the Turbo V6 continuing at Regal and Riviera.
Following the destruction of Buick 350 V8 after this year, Buick will only build a V6 engine as a result of GM's corporate-engined policies dictating the type of machines built by the various divisions to be used across the entire company. According to the plan, Buick will build a V6 engine, Pontiac will produce four-cylinder powerplants, Chevrolet will build four-cylinder engine, V6 and V8, and V8 for bigger and more expensive cars will be sourced from Oldsmobile and Cadillac. This means that from 1981 onwards, V8-powered Buicks will feature Oldsmobile engines, both gasoline and diesel.
1981
Only minor grille and trim changes are highlighting LeSabre 1981, which is still offered in the Basic and Restricted models. The modified grille now has five (not four) opening lines. The bidding machine includes a 231 cubic inch typically aspirated Buick V6 (standard on sedans and coupes though definitely less powerful for a car weighing around 4,000 pounds), or optional Olds 307 cubic inches V8 (standard on wagon, optional on sedan and coupe) and 350 cubic inches Oldsmobile-built V8 diesel (optional on all models). All petrol engines accept GM's "Control Computer Command" system for controlling fuel mix, forward motion, and emission control.
The three-speed Hydra-Matic Turbo Transmission is standard equipment with V6 and V8 diesel. New this year is a four-speed automatic overdrive transmission Turbo Hydra-Matic 200 4-R paired with a gasoline V8 engine to improve the fuel efficiency of the highway.
LeSabre and other GM cars for 1981 received new 35 PSI radial tires to improve rolling resistance and fuel economy.
1982-83
Some changes were made to Buick LeSabre for the years 1982-83 in addition to the revised grille and trim items. The base LeSabre sedan and coupe models were dropped for 1983 with LeSabre Custom now an entry-level model and paired with upscale LeSabre Limited models in both coupe and sedan models. The two-year engines offer includes a standard Buick 231 V6 or optional 252 V6, or optional Oldsmobile 307 (petrol) or 350 (Diesel) V8.
1984
New grille and wider and lower rear lights are among the changes of appearance for Buick LeSabre 1984, still offered in Custom and Limited models. The 252 V6 is dropped from the list of options but all other engines return including 231 V6 (standard on coupe and sedan), or optional Oldsmobile 307 V8 petrol (standard on wagon, optional on sedan and coupe) and Oldsmobile 350 Diesel V8 (optional all models).
1985
This will be the last year for LeSabre rear-drive before downsizing and converting to front-wheel-drive for 1986 (sedan and coupe only; LeSabre Estate Wagon's rear-drive will become a unchanged soldier in a few years). It is also the latest LeSabre sedan and coupe to feature body-on-frame construction, V8 power and traditional Buick All-coil suspension (1992-96 Roadmaster sedans will also be built similar). The top-line LeSabre Limited became the LeSabre Limited Collector Edition to mark the end of the era for sedans and rear-drive coupes.
The engine offer includes the standard 231 V6 (sedan and coupe) or the optional Olds 307 V8 (which comes as standard in the carriage) and Oldsmobile 350 diesel V8 (available on all models). 1985 307 receives roller lift to reduce friction.
Meanwhile, Wagon Estate continued largely unchanged until 1990.
The sixth generation (1986-1991)
The LeSabre 1986 was introduced on the new front-wheel H platform, having departed from the rear-wheel drive on the GM platform B. Join LeSabre on H-bodies including Oldsmobile Delta 88 and 1987 Pontiac Bonneville, which returned to full size after short runs as medium sizes on platform G. One of the most striking features of the LeSabre version of the H-body is that the hood is hinged forward rather than toward the rear near the cowl and windshield in the same way as the Buick Electra and Chevrolet Corvette of that era.
All of the new styling and front wheel drive implementations usher in a new era for LeSabre, which is a flush aerodynamic design. The most radical is probably the long-standing Buick's loss from the front fenders.
Most Buick LeSabre models from 1986 to 2005 are powered by a 3.6 liter (231 cubic-inch) Buick V6 engine. It starts with 150 hp (112 kW). This added axis balance to become the famous "3800" V6 for 1988, with 165 hp (123 kW). This machine increased to 170 hp (127 kW) in 1991 with the addition of Tuned Port Injection. The 1986 model, however, featured 3.0 liter (181 cubic inches) V6 as standard. Each year results in slightly different design changes. 1986 is famous for its sealed sealing lights, 1987 for more modern headlight substance with exchange lights and the introduction of seat belts mounted on doors. In 1988 the 3.8 engine was converted into 3800 (vin code C) motors, while 1989 saw little change in the layout of the bay's engine accessories (especially the battery position, the washing liquid tank, and the coolant overflow tank). For 1990 there was a change in the design of the front bumper/grille assembly and the design of different tail lamps, while 1991 was more or less identical to the 1990 model car in addition to the small power boost.
In 1986, there was a Grand Grand National model built to qualify coupe body styles for the NASCAR competition. LeSabre Grand National is one of the rarest of all Buick's ever made, with production numbers varying between 112 and 117 units. It's only available in black with gray interior.
After the end of Grand National production, the new LeSabre sport appeared in the form of LeSabre T-Type, which was offered from 1987 to 1989. LeSabre T-Type has many unique options set after the Regal Grand National and Regal Type T Model. Some of those options include black trim, black gray seats (only 1987), gray-black door panels, dashboard and gray trim, and a specific T-Type spoiler front and rear.
For 1990, the T-Type trim package was dropped due to slow sales and repositioning Buick in the GM hierarchy as a "Premium American Motorcars" maker rather than a sporty/performance model, rather than a falling role to Pontiac.
Started in 1989 and continued for several years, Buick LeSabre received an award from J.D. Power and Associates as one of the highest rated cars as far as customer satisfaction is linked to factors such as quality and reliability.
Seventh generation (1992-1999)
LeSabre was out in 1991 for the 1992 model, LeSabre redesigned along the same lines as Park Avenue the previous year. LeSabre was only available as a four-door sedan ("family style") from this point until the car was discontinued in 2005. The headlights are enhanced with separate sein lamp strips that wrap the lower front fascia. The rear fascia features a wider baggage mouth and a lower lift above the altitude to make it easier to load the luggage while the front is smoothed with simplified chrome prints and a non-existent bumper. The LeSabre also features GM's plastic body technology, with high-pressure plastic replacing the traditional steel in the front fenders.
The LeSabre engine from 1992-1995 is 3800 V6 (L27), which produces 170 hp (127 kW) and 225 lb Ã, Â · ft (305 Nm) Mobil 3513 lb (1593 kg) gets 18 mpg (13.1 L/100 km) in the city and 28 mpg (8.4 L/100 km) on the highway, which is slightly better than the 1991 model. The car accelerates to 60 mph (97 km/h) in 8.9 seconds and can cover a quarter mile in 16.9 seconds at 80 mph (129 km/h). The maximum speed is electronically limited to 108 mph (173 km/h).
The LeSabre is offered in two trim levels. Custom trim level is the base level. The Limited is a premium trim featuring wheels, front hood ornaments, and folding access panels in the rear seats to access the luggage. The car has an 18-gallon fuel tank, anti-lock brakes, and a power radio antenna located on the rear-side back panel of the passenger. Instrumentation includes gas gauge, speedometer, and gear indicator. Optional instrumentation includes tachometer and temperature, oil pressure, and charging voltage gauge.
In 1993, a special edition of LeSabre was sold to commemorate Buick's 80th birthday. In addition to standard Custom trim level equipment, this model includes badging, cassette player, cruise control, rear window defogger, power amplifier seat, carpet floor rug, exterior pinstripes, and wheel wheel or aluminum wheel cover options.
For 1996, LeSabre received a 3800 Series II powerplant, with a gain of 35 hp (26 kW). The engine boosted the fuel economy rating more than its predecessor, 19 MPG city and 30 MPG highway estimates of the US Environmental Protection Agency.
LeSabre was facelifted for 1997, moving the turn signal indicator to the front bumper instead of headlamp assembly. New gauge groups with tachometers appear. Interestingly, the front fenders switched from composite material to a more conventional galvanized steel substrate. Other minor changes are also influential, including different grille, different rear backup lights and different trims. The overall effect of this change is that the 1997-99 model looks a bit leaner than their predecessors. Despite the redesign of the exterior, one automotive magazine article around 1996-97 says the interior is "1970-something" which means it's a bit old-fashioned for cars from the mid-1990s.
In 1999, Flint, the Buick City assembly plant in Michigan, which built LeSabre and Pontiac Bonneville, was shut down and LeSabre's production moved to Hamtramck. The last LeSabre 1999 left the Buick City final line as the last Buick City made in June 1999.
The eighth generation (2000-2005)
2000 LeSabre was introduced in March 1999. Now built on GM G platform; But GM chose to continue to call it the H platform. The LeSabre is manufactured at Detroit GM/Hamtramck Assembly factory in Hamtramck, Michigan and Lake Orion Assembly, in Lake Orion, Michigan.
Some changes with the redesign include a new grille that does not open with a hood, and slightly smaller exterior dimensions. Although the size of the exterior is somewhat smaller, it still offers a similar interior space and more luggage space than previous models. The pollen filter is installed with this generation, and is accessed from within the passenger side compartment of the machine against the firewall. Custom and Limited trim levels continue to be offered.
In 2003, the Celebration Edition package was added in recognition of Buick's hundred years. The Celebration Edition features all standard equipment from Limited with a choice of White Diamond pearlescent or Crimson Pearl trichy paint schemes, blackened grille, 16 "chrome wheels and special badges.Otherwise optional or standard features on LeSabre include Stabilitrak, OnStar, EyeCue head-up display , all-weather traction control, automatic load-level, side airbag, tire pressure monitoring system, heated seats, dual zone climate control, and RainSense automatic windshield. Although created to commemorate the hundred-year Buick in 2003, the package remains available on 2004 and 2005.
Among the other packages offered at LeSabre include the Platinum Edition package in Customs 2004.
The standard engine, and only available, for the eighth generation LeSabre is the 3.8L Series II Buick 3800 V6 that provides:
- Power: 205 hp (153 kW)
- Torque: 230 lbÃ, Â · ft (312 NÃ, Â · m)
Termination
LeSabre was the best-selling full-size car in America when the car was discontinued at the end of the 2005 model year. It was replaced in 2006 by Luzick, the newly designed Buick aircraft carrier.
LeSabre last slid from the Orion Lake Michigan assembly line on June 18, 2004 (restoring the factory to build the Pontiac G6) and the last Hamtramck, Michigan LeSabre slid off the assembly line in mid-August 2005.
