Picking up where the Ventura model left off, the Grand Prix first appeared in the Pontiac line for 1962. It was essentially a standard Pontiac Catalina coupe with minimal outside chrome trim and a sportier interior (bucket seats and a center console). The performance-minded John De Lorean, head of Advanced Engineering at Pontiac, contributed greatly to the development of both the Grand Prix and the GTO. Early models had full access to the Pontiac performance option list, including the factory-race Super Duty 421 powertrain installed in a handful of 1962 and 1963 cars.

The full-size Catalina-based Grand Prix did very well through the 1960s, and is often credited with the move towards minimal exterior trim seen in the 1960s. Yet its clear resemblance to the other full-size Pontiacs caused some to consider it a lesser model than the other personal luxury cars. At the same time, the Grand Prix had a much stronger performance image than its competitors.

For 1963, the Grand Prix received revised sheetmetal shared with other full-size Pontiacs, but with its own squared-off roofline with a concave rear window that contrasted with the convertible-like roofline of the 1962 Grand Prix and continued on the 1963 to 1964 Catalina and Bonneville. Other distinctive styling cues found on Grand Prixs of this era included "hidden" taillight lenses and exclusive grillework up front. Inside, Grand Prixs had luxurious interiors featuring all-vinyl bucket seats separated by a center console with a floor shifter, storage compartment, courtesy light and optional tachometer or vacuum gauge. Starting in 1965, the Grand Prix was offered with a no-cost option bench seat with folding armrest as an alternative to the bucket seats and console.

Standard engines included a 303 hp (226 kW) 389 in³ V8 with four-barrel carburetor and dual exhausts from 1962 to 1964 and a 325 hp (242 kW) version of same engine from 1965 to 1966. Optional engines included higher output four-barrel and Tri Power versions of the 389 and larger 421 in³ V8s with up to 376 hp (280 kW). In 1967, the 389 was replaced by a 400 in³ V8 rated at 350 hp (261 kW) as the base engine while the larger 421 was replaced by a 428 in³ V8 with up to 390 hp (291 kW).

Transmissions included a standard three-speed manual and optional four-speed manual or a Hydra-Matic automatic transmission. The three-speed Roto Hydra-Matic was offered from 1962 to 1964 and replaced by a new three-speed Turbo Hydra-Matic for 1965 and later years.

A two-door hardtop was the sole bodystyle available on the Grand Prix for all years except 1967, when a convertible was also available as a one-year offering.

[edit] 1969

For 1969, DeLorean's team introduced an all-new Grand Prix based on a slightly stretched version of the intermediate GM A platform, which was dubbed the G-body. The previous platform was based on the 121 inch wheelbase from the Catalina, but in 1969 it was decreased to 118 inches. This smaller, lighter car at last had its own body, and brought a new level style and luxury into the intermediate class. The redesigned radiator, "Coke bottle" body shape and other Dusenberg styling cues gave the Grand Prix a feel of high luxury without the high cost. Unlike the previous generation, the new Grand Prix would only be offered as a hardtop. Even the model names took elements of old Dusenbergs (J and SJ trim).

It also refocused attention on performance, with increased installation percentages for manual transmissions and engine options up to the 390 hp (290 kW) 428 HO. Two engine sizes were offered, the base 400 ci and the 428 upgrade. Two power options were available in each engine size; a buyer could opt for a 265 hp 400 ci, 350 hp 400 ci, a 370 hp 428 ci and the high output 390 hp 428 ci. The 390 hp 428 ci option could run the 1/4 mile in about 14.1 seconds. It was both a marketing and an engineering landmark, being hailed at the time as "an Eldorado for the masses" and also in retrospect as the first successful downsizing of an American car.

Inside, the 1969 Grand Prix featured a sporty and luxurious interior with a wraparound cockpit-style instrument panel that placed virtually all controls and gauges within easy reach of the driver, and was named the "Command Seat". The "Strato" bucket seats were separated by a console slanted toward the driver which included the customary floor shifter, storage compartment and ashtray, integrated into the instrument panel. Upholstery choices included standard expanded Morrokide vinyl or cloth and Morrokide, or an extra-cost leather trim. The leather interior option also included a more luxurious cut-pile carpeting replacing the regular nylon loop rug that came with standard interior trims.

Innovations introduced on the 1969 Grand Prix included a concealed radio antenna, which amounted to two wires in the windshield; an optional built-in rear window defogger and side-impact beams inside the doors.

The 1969 Grand Prix also created a new market segment—the intermediate personal luxury car with sales ending up at over 112,000 units, well above the 32,000 full-sized Grand Prixs built in 1968. The similar Chevrolet Monte Carlo followed two years later. Ford and Chrysler responded by producing plusher versions of their Ford Torino and Dodge Charger intermediates, but both eventually created new models to enter the battle—the Ford Elite and Mercury Cougar XR-7 in 1974 and Chrysler Cordoba in 1975.

The basic 1969 bodyshell continued until the 1972 model year with a major facelift in 1971 but only minor detail revisions in 1970 and 1972.

[edit] 1970

Vertical grille inserts replacing the horizontal bars of the 1969, movement of "Grand Prix" nameplates from the lower cowls to the rear C-pillars and the vertical chromed louvers from the C-pillars down to the lower cowls. The optional 428 in³ V8 rated at 370 and 390 hp (291 kW) in 1969 was replaced by a new 370 hp (276 kW) 455 in³ V8 with an astounding 500 lb-ft of torque at 3100 rpm. The base 350 hp 400 ci engine was still standard, but a low-compression 400 ci engine was available with a two-barrel carburator. An automatic transmission was offered as a no cost option.

Interior trim also received minor revisions, and a bench seat with center armrest returned as a no-cost option to the standard Strato bucket seats and console. Bench seat-equipped Grand Prixs got a steering column-mounted shifter with the automatic transmission along with a dashboard-mounted glovebox, replacing the console-mounted shifter and glovebox of bucket-seat cars. Power front disc brakes became standard equipment this year.

Due to the success of the 1969 Grand Prix, other GM manufacturers followed suite and built their own intermediate cars. The Monte Carlo and Cutlass Supreme were very similar in dimension to the Grand Prix, but were 2 inches shorter and only shared the Grand Prix's roofline. The introduction of the cars cut into the Grand Prix's dominance, and sales dropped 40%. 65,750 Grand Prixs were built in 1970.

[edit] 1971

A new integrated bumper/grille and larger single headlights replacing the quad lights of 1969-70 models marked the introduction of the 1971 Grand Prix along with a new slanted boattail-style rear with taillights built into the bumper. Interior revisions amounted to new trim patterns for cloth and vinyl upholstery patterns for both the bench and bucket seats, but the leather interior option was discontinued. .

Engine choices included the standard 400 in³ V8 with four-barrel carburetor and dual exhausts, rated at 300 hp (220 kW); and the optional four-barrel 455 in³ V8 rated at 325 hp (242 kW). Both engines received substantially lower compression ratios (8.4 to 1 for 1971 compared to 10.25 to 1 in 1970) as part of a GM-corporate edict that required engines to use lower-octane regular leaded, low lead or unleaded gasoline beginning with the 1971 model year. Transmission offerings initially were carried over from previous years, including the standard three-speed manual, or optional four-speed stick or Turbo Hydra-Matic. However, at mid-year, Turbo Hydra-Matic automatic became standard equipment and the manual shifters were dropped. Variable-ratio power steering was made standard equipment as well. At mid-year, the SJ model received a sealed Delco X battery that no longer needed water refills.

New power ratings were put into effect, requiring manufacturers to post net horsepower with all accessories installed (vs. gross rating without the accessories). This system gave a more realistic measure of horsepower that customers actually saw. The base 400 four barrel engine then produced only 255 horsepower after the switch to the net-rating system, and the 455 found in SJ models also dropped in power to 260 horsepower (net). Customers who wanted the higher powered 455 SJ model paid $195 to get Rally gauges, body-colored mirrors, SJ badging, a no maintenance AC Delco battery and other amenities. 1971 looked to be a good sales year for the Grand Prix, but in mid-September, a labor strike haulted production. The strike also delayed the production of the second generation Grand Prix by one year in 1973. Production numbers for 1971 were lower than 1970 with only 58,325 units being produced. This was possibly due to the low horsepower ratings and improvements in the competition (Cutless, Monte Carlo).

[edit] 1972

Minor styling revisions included a new cross-hatch grille up front and triple cluster taillights in back. Inside, the burled-elm trim was replaced by a new teakwood design and upholstery trim patterns for vinyl and cloth selections were revised for both bucket and bench seat offerings. Engine offerings remained the same as before with the major change being the change in horsepower measurements from the previous gross method on a dynamometer to the new net ratings as installed in a vehicle with accessories and emission equipment which made the horsepower ratings of 1972 models much lower "on paper" than their 1971 counterparts though actual performance didn't change much between the two years. Under the new net horsepower system, the standard 400 in³ V8 with four-barrel carburetor was rated at 250 hp (186 kW) while the optional 455 in³ V8 with four-barrel carb was rated at 300 hp (220 kW).

At mid-year, Pontiac released a radial tire option for the Grand Prix, which increased the wheel diameter from the standard 14-inch (360 mm) to 15-inchers. The radial donuts, provided by the division's usual tire suppliers, included Firestone 500s and B.F. Goodrich Lifesaver T/As. This was the first time that Pontiac offered a radial tire option which actually became a reality. In 1968, Pontiac announced a radial tire option for the GTO that was quickly discontinued due to production problems.

An all-new Grand Prix was scheduled for 1972. However, a 67-day corporate-wide strike at GM in late 1970 that hobbled the 1971 model introduction set back 1972 model production plans and the new A and G-body cars planned for 1972 were delayed for introduction by one year to the 1973 model year. Production numbers reached 91,961 units in 1972 for the Grand Prix.

[edit] 1973

All A-bodies, including the Grand Prix, were redesigned for 1973. This generation was larger and heavier, due partly to the federally mandated 5 mph (8 km/h) crash bumpers. Although large V8s were still available, performance was on the decline due to another federal standard—a new emissions control system. The most notable styling feature of this generation was the appearance of the fixed opera window, replacing the previous disappearing rear side glass. This year's Grand Prix switched from pillarless hardtop design to a pillared "Colonnade" hardtop with frameless door glass as did all GM intermediates in response to proposed federal safety standards regarding roll-over protection that would have ultimately spelled the end of pillarless and convertible bodystyles, a mandate that never materialized. The 1973-77 GM intermediates with their pillared hardtop design were often referred to as "Colonnade hardtop coupes" or "Colonnade hardtop sedans".

Front and rear styling of the 1973 Grand Prix turned out be an evolution of the 1971 to 1972 models with a vertical-bar V-nose grille and single headlamps along with the new federally mandated 5 mph (8 km/h) front bumper. The rear featured a revised boattail-like trim with square-taillights above the bumper.

Inside, a new instrument panel continued the wraparound cockpit theme of previous models with new African Crossfire Mahogany facing on the dashboard, console and door panels, which was "real" wood in contrast with the simulated woodgrain material found in most car interiors during that time. The Strato bucket seats were completely new with higher seatbacks and integrated headrests in Morrokide or scivvy cloth trims, and optional recliners and adjustable lumbar support, with a notchback bench seat offered as a no-cost option.

The standard drivetrain consisted of the four-barrel 400 in³ V8 rated at 230 hp (172 kW) and the Turbo Hydra-Matic transmission. Also standard were power steering and power brakes. A four-barrel 455 in³ V8 was optional and included with the "SJ" option that also added a rally gauge cluster and a radial tuned suspension with front and rear sway bars, Pliacell shock absorbers and radial-ply tires.

Although the Third Generation Grand Prix was indeed bulkier and heavier than its predecessor, handling was very good for such a large car, due to improvements in suspension design that gave better stability and cornering. The introduction of radial-ply tires was also a boon for handling. GM's "A" body cars' suspensions were based on the road-hugging Chevrolet Camaro during this production run.

[edit] 1974

The 1974 Grand Prix received a revised split grille with vertical bars that was entirely above the bumper. Out back, the boattail effect was softened somewhat thanks to a new federally mandated 5 mph (8 km/h) bumper added to the similar mandated front bumper introduced in 1973. The license plate and fuel filler were moved above the bumper and taillight lenses were revised. Interior trim remained virtually unchanged from 1973 with standard seating choices including Strato bucket seats with center console or notchback bench seat with armrest and cloth or Morrokide upholstery. The bucket seats were available with optional recliners and adjustable lumbar support. However, the real African Crossfire Mahogany trim was replaced by a simulated material for the instrument panel due to splintering problems on '73 models, but the "real" wood was continued on the console and door panels for another two years. Also, a new cut-pile carpeting replaced the nylon loop rugs of previous years.

Engines were carried over from 1973 including the 400 in³ V8 (standard on the Model J) and 455 in³ V8 (standard on the Model SJ, optional on the Model J). Turbo Hydra-Matic transmission, variable-ratio power steering and power brakes were standard equipment on both models. In addition to the 455 V8, the Model SJ also added a Rally Gauge Cluster, "SJ" identification and a radial-tuned suspension similar to Pontiac's Grand Am. Radial tires were also a new option on the Model J this year.

Sales of Grand Prixs for the 1974 model year dropped from 1973's record of around 150,000 units to just under 100,000 units primarily due to new competition in the intermediate personal-luxury car market from a new upsized Mercury Cougar XR-7 coupe. Still 1974 was the third-best selling year to date for the Pontiac Grand Prix.

[edit] 1975

A revised grille with fewer vertical bars and revised taillight lenses marked the 1975 Grand Prix. Mechanical changes this year included the addition of GM's High Energy electronic ignition and a catalytic coverter that mandated the use of unleaded gasoline. Radial tires became standard on all models.

A new luxury LJ model was added the lineup, positioned between the base Model J and the sporty SJ series. The LJ included pinstriping and a luxurious velour interior trim. Speedometers were revised with numerals now topping at 100 mph (200 km/h) rather than the 120 or 140 mph (230 km/h) readings found in previous years and speed readings in kilometers were added.

The addition of the catalytic converter spelled the end of dual exhaust pipes for 1975 and detuning of engines. The 400 in³ V8 (standard on J and LJ models) dropped from 230 to 180 hp (134 kW) while the 455 in³ V8 (standard on SJ, optional on J and LJ) was detuned from 250 to 200 hp (150 kW). New for 1975 was a more economical 170 hp (127 kW) 400 cubic-inch V8 with two-barrel carburetor, which was available as a no-cost option on J and LJ models.

[edit] 1976

A new split vertical bar "waterfall" grille and quad rectangular headlights in front and revised taillight lenses out back highlighted the 1976 Grand Prix. The same three model designations continued (J, LJ and SJ) with the LJ and SJ offering the same trim and equipment levels as in 1975 with the exception being the SJ downgraded to a standard 400 in³ V8.

The base Model J underwent a number of content changes to cut the base price by around $500 to be more competitive with other mid-sized personal luxury cars. Those changes for the "J" included a smaller 160 hp (119 kW) 350 in³ V8 as the base powerplant and some downgrading of interior trim that included a new notchback bench seat made standard equipment and the Strato bucket seats/console moved to the "option" list. Also, custom features such as a cushioned steering wheel and custom pedal trim plates were moved to the option list on Model J, but remained standard on LJ and SJ, both of which also continued to include Strato bucket seats as standard equipment. All models got a new simulated rosewood trim for the dash, door panels and console (with bucket seats) that replaced the African Crossfire Mahogany trim of previous years. Upholstery choices included cloth or Morrokide vinyl bench or bucket seats on the Model J, velour buckets on the LJ or Morrokide buckets on the SJ. Leather interior trim was a new extra-cost option available with the Strato bucket seats and LJ and SJ models. Both the "LJ" and "SJ" models came standard with a 180 hp (134 kW) 400 in³ V8 that was optional on the Model J. The 200 hp (150 kW) 455 in³ V8 was optional on all models. In celebration of Pontiac's 50th anniversary in 1976, a number of special edition Grand Prix painted gold were produced. These models featured removable Hurst T-tops, Rally II wheels and other distinctions but were mechanically similar to the regular models.

Grand Prix production set a new record of over 226,000 units during this Bicentennial year, making the GP only second in sales in its market segment to Chevy's Monte Carlo.

[edit] 1977

Revised grille work with fewer vertical bars, a stand-up hood ornament and revised taillight lenses with "GP" logos highlighted the 1977 Grand Prix, which was the final year for the 1973-vintage bodyshell which was set to be replaced by a downsized GP for 1978. The same three models (J, LJ and SJ) were carried over with engine revisions. The base Model J got Pontiac's new 135 hp (101 kW) 301 in³ V8 as standard equipment, which was a bit too small and underpowered to propel a 4,000-pound car. Optional engines included a 160 hp (119 kW) 350 in³ V8 or 180 hp (134 kW) 400 in³ V8; those two engines standard on the LJ and SJ models, respectively.

Each of those engines were Pontiac-built units as in previous years, but offered in 49 of the 50 states. Due to the fact that Pontiac's own V8 engines could not meet the more stringent California emission standards set for 1977, all Grand Prixs (and other Pontiac models) sold in California were powered by Oldsmobile-built engines including Lansing's 350 in³ Rocket V8 for J and LJ, and the 403 in³ Rocket V8 standard on the SJ and optional on the other two GPs in California. Due to a shortage of Olds 350 engines resulting from record sales of Cutlasses and reduced production of that engine due to a plant conversion to build a Diesel V8 beginning in 1978, a few '77 Grand Prixs destined for California reportedly came off the line with a Chevrolet-built 350 in³ V8.

Grand Prix sales soared to an all-time high of over 270,000 units for 1977, the last year for this bodystyle, despite competition from a newly-downsized and lower-priced Ford Thunderbird introduced this year and a restyled Mercury Cougar XR-7 whose bodyshell switched to the T-Bird this year from the discontinued Ford Torino/Mercury Montego.

[edit] 1978

1978 brought a downsizing of the Grand Prix and the other A-bodies. This version of the A-body also received some sheetmetal revisions in 1981. The 1978 GP was about a foot shorter and 600 pounds lighter than the 1977 model with an overall length of 200 inches (5,100 mm) and a 108-inch (2,700 mm) wheelbase.

For the first time in Grand Prix history, a V8 engine was not standard equipment. In order to meet Corporate Average Fuel Economy (CAFE) mandates set after 1973-74 energy crisis, a Buick-built 231 in³ V6 was standard equipment on the base model (formerly the Model J) and two versions of the Pontiac 301 in³ V8 (Chevy 305 V8 in California) were optional. The luxury LJ model came standard with the 135 hp (101 kW) 301 V8 with two-barrel carburetor while the sporty SJ was powered by a 150 hp (112 kW) 301 V8 with four-barrel carburetor. A floor-mounted three-speed manual transmission was standard equipment with the V6 on the base model and the three-speed Turbo Hydra-Matic automatic was optional. Turbo Hydra-Matic was standard on LJ and SJ models and base models with either of the optional V8 engines. Standard seating choices by model included a notchback bench seat with cloth or Morrokide vinyl in the base GP, a pillowed velour cloth notchback bench seat in the LJ or Strato bucket seats in cloth or Morrokide in the SJ. The Strato buckets were optional on the base GP and a 60/40 split bench was optional on both base and LJ models. Viscount leather upholstery was available with bucket seats on SJ models.

[edit] 1979

A new crosshatch grille and revised taillight lenses were the only appearance changes made to the 1979 Grand Prix. The same models, base, LJ and SJ continued as before as did the basic engine lineup including the 231 cubic-inch Buick V6 standard on base and LJ models, the 135 hp (101 kW) 301 cubic-inch Pontiac V8 with two-barrel carburetor that was optional on both of those models, and the 150 hp (112 kW) 301 V8 with four-barrel carburetion that was standard on the SJ and optional on the other models. Transmissions remained the same as before with the three-speed manual standard with the V6 engine on the base model and automatic transmission optional. The automatic transmission was standard on LJ and SJ models and all models when a V8 engine was ordered. Again, the Pontiac V8s were not available in California, where they were replaced by Chevy 305s rated at 140 and 160 hp (119 kW). A new and one-year-only option this year was a four-speed manual transmission available with the 301 four-barrel or two barrel V8 on all models. Only 232 4 speed/301 V8 cars were built.

[edit] 1980

The 1980 Grand Prix returned to a vertical bar grille and featured new taillight lenses with "GP" logos. Automatic transmission was standard equipment on all models and the two-barrel 301 Pontiac V8 was replaced by a new 265 cubic-inch V8 rated at 125 hp (93 kW). The Buick 231 V6 and the four-barrel version of the Pontiac 301 V8 were carried over from the previous year as was the Chevy 305 V8 offered in California.

[edit] 1981

A minor reskinning of the sheetmetal for improved aerdynamics marked the 1981 Grand Prix along with a new grille design and revised tail section. The sporty SJ model was dropped and a new ultra-luxurious Brougham series was now the flagship of the Grand Prix line featuring a plush cloth interior similar to the full-sized Bonneville Brougham and standard power windows and other amenities. The base and LJ models continued as before. All models now came standard with the Buick 231 V6 with the 265 cubic-inch Pontiac V8 available as an extra cost option (Chevy 305 V8 in California). The 301 V8 was discontinued and a new option this year was the Oldsmobile-built 350 cubic-inch Diesel V8, which was not often ordered due to high cost of around $700 and poor reliability. The year 1981 was also the last for Pontiac Motor Division to offer its own V8 engine due to an emerging GM corporate engine policy that determined Pontiac would build only four-cylinder engines and Buick only V6 engines, leaving Chevrolet and Oldsmobile to build V8 engines for most GM cars and trucks, while Cadillac would produce its own aluminum-block V8 that debuted in 1982. From 1982-on, all V8-equipped Pontiacs were equipped with Chevy or Olds engines.

[edit] 1982

The 1982 Grand Prix was a virtual re-run of the 1981 model with no appearance changes to note. No gasoline-powered V8 engines were offered this year, leaving only the standard 231 cubic-inch Buick V6, a larger Buick 252 cubic-inch V6 and the Olds 350 Diesel V8. The A-body line became front-wheel-drive, leaving the rear-wheel-drive midsize platform as the G-body. The downsized four-door Bonneville was now related to the Grand Prix.

[edit] 1983

No appearance changes for the 1983 GP. Only significant change to note was the 252 V6 was discontinued and the gas-powered V8 returned after a one-year absence in the form of a 150 hp (112 kW) Chevy 305. 1983 also marked the end of the LJ series, as the LE model would be added in 1984.

[edit] 1984

New grille inserts and minor revisions to the tail section marked the 1984 Grand Prix. The base and Brougham models continued as before but the LJ was replaced by a new LE model. Same engines continued as before including the Buick 3.8 liter (231 cu.-in.) V6, Chevy 5.0 liter (305 cu.-in.) V8 and Olds 5.7 liter (350 cu.-in.) Diesel V8. A new option this year was the Turbo Hydra-Matic 200-4R four-speed overdrive automatic available with the 305 V8 for improved highway gas mileage.

[edit] 1985

For 1985, the minor trim changes to the front grill inserts and last year for the flat rear deck panel in the interior were the only changes. In 1986, laws mandated cars to have a third brake light. Some options for the 1985 Pontiac Grand Prix included the rare aluminum turbo finned wheels, rare chrome painted plastic hub caps, full size spare tire, AM/FM Cassette stereo system with 4 speakers, and rally gauge package. The standard engine for 1985 was the 110 horsepower Buick built 3.8 liter (231 cu.-in) V6.

[edit] 1986

In 1986 a 2+2 model was offered for homologation of an Aerocoupe body for NASCAR competition. 2+2 specific pieces are an aero nose, bubble rear glass and a fiberglass trunklid with integral spoiler. All 2+2 were optioned similarly with a corporate 305 four barrel, 200-4R 4 speed automatic transmission and 3.08:1 rear axle ratio. All were silver with 2+2 decals and striping, with 15X7 steel rally II wheels. Approximately 1225 1986 Grand Prix 2+2's were built in 1986.

[edit] 1988

The first front-wheel drive W-body Grand Prix coupe was built on January 12, 1988. This generation Grand Prix was built in Kansas City, Kansas. Three model designations were available: base, LE, and SE. The Grand Prix LE had standard air conditioning, power windows, and power locks. SE models got the 2.8 L V6 engine along with other amenities, such as "AQ9" 14-way pneumatic power seats, a driver information computer in the center console, and a sport gauge cluster. The Grand Prix was Motor Trend magazine's Car of the Year for 1988. An unusual feature replaced the keyed lock on the glove compartment with a three digit combination lock.

[edit] 1989

In 1989, air conditioning became standard on all models, and a 3.1 L multi-port fuel injected V6 replaced the 2.8 L engine. Another model designation to appear in 1989 was the Turbo Grand Prix. This version started as an SE minus three available options: leather seats, a sunroof, and in 1990, a CD player. These were shipped to McLaren/ASC to get a "B4M" body kit with special molding and hood louvers, and a modified 3.1 L V6 with a Garrett T-25 turbocharger and intercooler. The Turbo also included a full-analog instrument cluster that would soon become the base of the 1990–1993 sport cluster.

[edit] 1990

In 1990, the base model was dropped in favor of a sedan version (replacing the 6000 and the Canada-only Tempest), entering production on September 12, 1989. The new Grand Prix STE (Special Touring Edition) had special seats, audio systems, and Driver Information Centers. The seats were 8-way pneumatic with adjustable lumbar supports. The audio systems were 8-speaker with full graphic equalizer and a "gain" slider to control bass. The Driver Information Centers were quite a step up from the more basic ones available in the SE and Turbo. In addition to the basic information that the SE LCD counterparts displayed, the STE vacuum fluorescent display DICs had a full light and door monitor with icons for all the major vehicle systems. The STE also had a front and rear lightbar in addition to a trunk-panel. A turbocharged STE was also available for this year. A 2.3-liter 4-cylinder Quad 4 was also available in this model year although not a popular option.

[edit] 1991

In 1991, the turbo models were dropped in favor of a new GTP model. This included the new 3.4 L Twin Dual Cam engine along with all available options and a modified version of the B4M body package. The composite headlights were replaced with mini-quads and the package was renamed B4U. An optional but rare 5 speed manual (Getrag 284) was included and only available with the 3.4 Litre. An SE sedan also became available that year. Like the 1990 model year a 2.3-liter 4-cylinder Quad 4 was also available in this model year although not a popular option.

[edit] 1994

Grand Prix gets redesigned front/rear fascias and ground effects, as well as a new instrument panel with dual airbags, new gauges, and controls. STE, LE, and GT designations are gone. GT and GTP become option packages on SE coupe. A GT package is available on SE sedan, and includes 3.4 L V6, alloys, low-profile tires, ABS, and sport suspension. Front seatbelts are anchored to pillars instead of doors on sedan; coupe retains door-mounted belts. Twin-cam 3.4 L V6 is up 10 hp (7 kW). Five-speed manual and three-speed automatic transmissions are dropped in favor of four-speed automatic. Coupes gain standard equipment, including 16-inch (410 mm) alloys, cruise, and leather-wrapped steering wheel with integral radio controls. A redesigned 160 hp (119 kW) 3100SFI V6, Gen III, replaces old 3.1 L V6.

[edit] 1995

Brake/transmission shift interlock is added. This year model would feature the GM 3100 in the GT. GT coupe dropped in favor of GTP Package. GT sedan continues. Variable-effort steering is added to GTP and GT. New aluminum wheels debut on GT and GTP. Coupes can be equipped with a White Appearance Package, which includes color-keyed alloys and special pinstriping. Floor consoles are redesigned on models with bucket seats.

[edit] 1996

3.4 L DOHC V6 gains 5 hp (4 kW) with intake and exhaust improvements. All Grand Prix coupes get a sport package with five-spoke alloy wheels and dual exhaust. This is the last year for the fifth-generation Grand Prix.

[edit] 1997

In 1997, the W-bodies received a major redesign. The first 1997 Grand Prix was built on August 12, 1996. Promoted widely for its "wide track" appearance and racy styling, the second generation W-body Grand Prix sold well. There were 2 trim levels available in 1997; the SE and GT (available in coupe and sedan body styles). The Grand Prix came as a base SE sedan or a sportier GT coupe and sedan, as well as with a high-performance GTP package--available for GT models in either body style. Coupes and sedans shared similar styling, except for rear doors and quarter panels. The GTP was an option package under the GT trim level, and later became its own trim level. The base engine on the SE was the 3.1 liter V6. The GT had a 3.8 liter V6 (3800 Series II) which was an option on the SE. The 3800 Series II was on the Ward's 10 Best Engines list for 1995 through 1997. The GTP added an Eaton M90 supercharger (also used in the 2000-2005 Bonnevilles) to the 3.8 liter, boosting power from 195 hp (145 kW) to 240 hp (179 kW). GTP trim level featured a "performance shift" button on the shifter, that raised the transmission shift points. Also standard was a tire-pressure monitor.

[edit] 1998

Few Changes occurred this year, except that traction control now was available with the supercharged engine. Airbags were "depowered" to deploy with reduced force. The tire-pressure monitor was dropped. To add some excitement, Pontiac also launched a special pace car model. This model celebrated the 40th running of the Daytona 500 on February 15, 1998. The pace-car replicas, had special Medium Gulf Blue Metallic paint, unique "Sparkle Silver" 16-inch torque star aluminum wheels, custom decaling, a plaque notating the specific model number, and custom door panels. 1500 were produced, with 200 of the 1500 getting sunroofs.

[edit] 1999

Detail changes marked the '99 editions of Pontiac's midsize coupe and sedan. The nonsupercharged V6 engine gained five horsepower. GT models got a standard rear spoiler this year. The coolant overflow reservoir was relocated from being in front of the intake box to being mounted to the passenger strut tower. Available 16-inch alloy wheels came in a new 5-spoke design. The one new option was a Bose 8-speaker audio system.

[edit] 2000

Wheels were revised and the nose restyled on Pontiac's midsize coupe and sedan. The standard 3.1-liter V6, installed in SE models, gained 15 horsepower (now 175). New standard equipment included rear child-seat anchors and an antitheft system that disabled the starter unless the proper ignition key was used. Pontiac also launched a Daytona 500 pace-car replica, with silver paint, unique 16-inch aluminum wheels, functional hood vents, a decklid spoiler, bright exhaust tips, and Daytona decals. Only 2000 were planned. By now, the list of Grand Prix competitors included the Toyota Solara coupe and Chevrolet Impala sedan.

[edit] 2001

OnStar, formerly available on all Grand Prixs, was made standard on GTP, optional only on GT for 2001. SE got revised frontal styling, standard rear spoiler, and in-trunk emergency release; dual-zone manual climate-control was standard on GTP.

[edit] 2002

New for 2002 was a 40th Anniversary Package which included a rear spoiler, hood ducts, chrome wheels, Dark Cherry paint, and unique red-and-gray interior trim. The SE gained standard cruise control and dual-zone climate control, and GTs got a standard power driver's seat and CD player. This was the last year of the sporty two door coupe. The SE model has one exhaust

[edit] 2003

Pontiac dropped the 2-dr coupe version of its midsize car for 2003 and makes antilock brakes and traction control optional instead of standard on most of the remaining sedans. Grand Prix was redesigned for 2004.

The Grand Prix was updated for 2004 on a revised version of the GM W platform. The first 2004 Grand Prix was built on May 5, 2003. The Grand Prix came in four different option groups; GT1, GT2, GTP, and GTP Comp-G ("Competition Group").

The base model GT1 and fancier GT2 have the Series III 3800 V6, putting out 200 hp (150 kW) and 230 lb-ft (310 Nm) of torque, while both GTPs have the supercharged (Eaton Gen 5 Supercharger) 3800 Series III V6 engine with 260 hp (195 kW) and 280 lb-ft (380 Nm) of torque.

A Competition Group (Comp-G) package was available for the GTP that included red painted brake calipers (same brakes as the 'standard' GTP), sport tuned suspension, heads-up display, 4 speed automatic transmission with paddle-style TAPshift, StabiliTrak dynamic control system, 3.29 axle ratio, performance tires and Magnasteer II. Also, a 10 spoke light weight wheel was standard with the Comp-G package but could be 'upgraded' to the GTP optional wheel.

Commencing with this generation, the 2 door coupe version of the Grand Prix was no longer an available body style. The timing of the disappearance of the Grand Prix coupe coincided with GM's reintroduction of the 2 door Pontiac GTO.

[edit] 2005

The Grand Prix remains basically unchanged from 2004. With the Base sedan, GT, GTP, and the new GXP. The base model and GT still have the naturally aspirated 3.8 L V6 with the GTP having the 3.8 L V6 w/ supercharger. Also, the Comp-G package was still available for the GTP with an added door emblem denoting the Comp-G package.

The GXP powerplant is the LS4 V8, a 5.3 liter Displacement on Demand (active fuel management) engine based on the legendary LS1 block. It has a shortened crankshaft, and a host of other modifications to make it fit into a FWD vehicle. The GXP also has a 4 speed automatic transmission with paddle-style TAPshift, heads-up display, vented cross drilled brakes with PBR calipers, performance tuned suspension with Bilstein gas-charged struts (sits about 9 mm lower than other GP models), Magnasteer II, and StabiliTrak dynamic control system. Also, the DIC will display G-Force (maximum achieved for lateral, acceleration, and deceleration) information when the car is not moving. Cosmetically, the GXP differs from the other models with more aggressive bodywork including a different front clip, engine cooling ducts on the front quarter panels, a different rear bumper, and twin-dual polished exhaust. The Grand Prix GXP also offers a unique feature of the different-width 18-inch (460 mm) polished Alcoa Forged aluminum wheels. The front wheels are eight inches (203 mm) wide, while and the rear wheels are seven inches (178 mm) wide.

[edit] 2006

For 2006, little has changed for the Grand Prix. The three options are the Grand Prix, powered by the 3800 Series III V6, the GT, now powered by the 3800 Series III Supercharged V6, and the GXP, powered by the LS4 V8. The GTP designation (and with it the Comp-G) is dropped.

[edit] 2007

For the 2007 Model Year, A "Special Edition" body package was added, and the GT models received a new "Diffuser" style rear bumper. The model designations remained Base, GT,and GXP. Also, the active displacement management capability on the 5.3L V8 (GXP) was renamed to "Active Fuel Management" from "Displacement on Demand".

[edit] 2008

The Pontiac Grand Prix remains unchanged for 2008. Pontiac no longer offers the GT trim, but continues to offer a base and GXP trim. The base trim is offered with a 200-horsepower V6 engine and 16-inch wheels, while the GXP trim includes a 303-horsepower V8 engine with a firmer suspension, performance tires, a heads-up display and 18-inch wheels. ^[1] A few new colors were also added for the 2008 model year. Grand Prix production phased out and will be replaced with the rear-wheel drive Pontiac G8. The last Grand Prix rolled off the vehicle assembly line on November 30, 2007.

[edit] 2008 Recall

In March of 2008, GM announced a plan to recall all 1997-2003 Grand Prix models with the supercharged 3.8 liter engine (GTP and GTX models) due to a problem which causes fires in the engine compartments of these vehicles. Over 230 fires were reported. This recall will affect over 200,000 vehicles. GM sent a letter to owners of these vehicles on March 13, 2008, instructing owners of these vehicles not to park in garages or carports until the problem is resolved. ^[2]
