First generation (1967–1969)
The first generation Firebird had characteristicEngines
Second generation (1970–1981)
The second-generation debut for the 1970 model year was delayed until February 26, 1970, because of tooling and engineering problems; thus, its popular designation as a 1970½ model, while leftover 1969s were listed in early Pontiac literature without a model-year identification. This generation of Firebirds were available in coupe form only; after the 1969 model year, convertibles were not available until 1989. Replacing the "Coke bottle" styling was a more "swoopy" body style, while still retaining some traditional elements. The top of the rear window line went almost straight down to the lip of the trunk lid. The new design was initially characterized by a large C-pillar, until 1975 when the rear window was enlarged. Originally, the "wraparound" style window that occupied more of the c-pillar was initially supposed to be the deisgn, but problems with the glue and sealing the rear window led to the flat style window being used until the re-designed body in 1975. This style became the look that was to epitomize the F-body styling for the longest period during the Firebird's lifetime.

The first year of the second generation Firebird began offering a wider array of model subtypes and marked the appearance of the Firebird Esprit, and the Firebird Formula. The Firebird Esprit was offered as a luxury model that came with appearance options, the deluxe interior package, and a Pontiac 350 as standard equipment. The Formula was advertised as an alternative to the Trans Am and could be ordered with all the options available to the Trans Am with the exception of the fender flares, shaker scoop, and fender heat extractors. The base model Firebird came equipped with a inline-six. The Firebird Esprit and the Firebird Formula came standard with the . The Esprit could be upgraded to a two barrel carbureted , while the Formula could be optioned to receive the L78 4 barrel 400 that produced or the L74 Ram Air III 400 . There were two Ram Air engines available for the 1970 Trans Am: the L74 Ram Air III 400 ( in the GTO) and the L67 Ram Air IV ( in the GTO) that were carried over from 1969. The Ram Air IV was exclusive to the Trans Am, and could not be ordered on any of the lower Firebird models. The difference between the GTO and Firebird engines was that the secondary carburetor's throttle linkage had a restrictor which prevented the rear barrels from opening completely, adjusting the linkage could allow full carburetor operation resulting in identical engine performance. For the 1970 and 1971 model years, all Firebirds equipped with radios had the antennae mounted "in-glass" in the windshield.1971
The 1971 model year had a few minor changes to the Firebird. Fenders across all models now featured a one-year-only exhaust vent seen on the lower half of the fenders. The interior options also changed to the newer style collared bucket seats in the deluxe interior, and the previous year's seats with the headrest were no longer available. The rear seat console was introduced as an option, and Honeycomb wheels became available for all Firebirds. 1971 saw changes to the way the engines were rated from the factory. GM mandated that engines no longer use SAE Gross horsepower ratings and use the SAE Net power ratings to help alleviate the rising cost of insurance for performance vehicles. The compression ratio was also lowered for some of the models, de-tuning the power rating for some of the engines as part of new requirements for low-leaded fuels, however, the engine options remained mostly unchanged from 1970. As the limit for the compression ratio was lowered, this allowed for larger displacement engines to become available. The 455 was now available for the Firebird in two configurations. The 455 engine was available in the L75 version and the LS5 HO version. Both the 455 and 455 HO were available as engine options for the Firebird Formula, but the Trans Am received the 455 HO as standard equipment.1972
During a 1972 strike, the Firebird (and the similar F-body1973
In 1973, the Trans Am added two new colors, Buccaneer Red and Brewster Green. Other exterior upgrades included the updated more modern nose bird. The new hood bird was option “RPO WW7 Hood Decal”, a $55 option exclusive to Trans Am. The “Trans Am” decals were larger than previous versions and shared the same accent color schemes as the hood bird. Inside the 1973, Firebird the standard interior equipment was almost the same as prior years. The new “Horse Collar” optional custom interior featured new seat coverings and door panels. The 1973 Firebird also had to meet the new safety and emissions requirements for 1973. There were extra steel reinforcements in the bumper and core support to the fender. The 1973 Trans Am engine displaced 455 cubic inches in the base L75 and the Super Duty LS2 option. The base 455 produced 40 fewer horsepower than the round port Super Duty 455. Horsepower for the base L75 455 was rated at 250@4000 rpm and 370 lb/ft @2800 rpm. Pontiac removed the H.O. designation from the base engine, and simply decaled the now non-functioning shaker with “455”. The “all hand-assembled” LS2 SD455 engine was rated at 290@4000 rpm and 395 lb/ft @3600 rpm. All Pontiac engines included a new EGR system, which delayed the SD-455 program until late into the production year. The shaker decal on the scoop read "SD-455". The 1973 Trans Am introduced "Radial Tuned Suspension". When ordered, it included 15-inch radial tires. This delivered a more comfortable ride while also providing better cornering. The 1973 Trans Am production was up over previous years, the L75 455 production was 3,130 with automatic and 1,420 with manual transmission. The special ordered $550 Option LS2 SD-455 production saw 180 automatics and 72 manuals.1974
Curb weights rose dramatically in the 1974 model year because of the implementation of telescoping bumpers and various other crash- and safety-related structural enhancements; SD455 Trans Ams weighed in at in their first year of production (1974 model year; actually 1973). The 1974 models featured a redesigned "shovel-nose" front end and new wide "slotted" taillights. The 400, 455, and SD-455 engines were offered in the Trans Am and Formula models during 1974. A June 1974 test of a newly delivered, privately owned SD-455 Trans Am. This appeared in ''Super Stock and Drag Illustrated''. With an unmodified car and a test weight of 4,010 lbs the testers clocked 14.25 seconds at 101 mph. The car had an automatic and A/C. Also, the factory rating of 290 hp was listed at 4,400 rpm while the factory tachometer has a 5,750 rpm redline. A production line stock 1974 SD455 produced 253 rear wheel HP on a chassis dyno, as reported by ''High Performance Pontiac'' magazine (January 2007). This is also consistent with the 290 SAE net horsepower factory rating (as measured at the crankshaft). A 1974 Firebird was driven by Jim Rockford in the pilot movie and the first season (1974–1975) of ''1975
The 1975 models featured new wraparound rear windows that curved out to occupy more of the B-Pillars, but the rear body shape and bumper remained unchanged. The turn signals were moved up from the valance panel to the grills which helped distinguish the 1975 from the 1974 front end as they are otherwise similar. This was also the last year of the larger profile larger snout Formula hood for the Firebird Formula. The Super Duty engine and TurboHydramatic 400 three-speed automatic were no longer available in 1975. Due to the use of catalytic converters starting in 1975, the TH400 would not fit alongside the catalytic converter underneath the vehicle. The smaller TurboHydramatic 350 automatic was deemed suitable as the power output for the engine had significantly decreased from the earlier years. TH350 drew less power and also did not require an electronic kickdown system. The Pontiac L78 400 was standard in the Trans Am and the 455 was optional for both 1975 and 1976 models. 1975 also saw the start of the "500577" cast 400 engine blocks enter production. The 500577 cast blocks were considered a weaker cast, as they had a lower nickel content, had metal shaved off in the lower journals of the block to decrease the overall weight, cost, and emissions to meet the tightening smog restrictions. These blocks were used until the W72 engine reverted to the original specifications from the start of the decade with the 481988 cast in late 1977. Originally, the L75 455 7.5L V8 was dropped entirely, but it returned mid-year, available only with a four-speed Borg Warner Super T-10, and it was no longer available for the Formula. Although it was brought back as the "455 HO", it was not the same engine as the 1971-72 LS2 455 HO seen in the earlier Firebirds. It was a standard D-port engine with a low profile camshaft and restrictive exhaust system that was also seen in the larger body Pontiac platforms. Power output was restricted to 200 HP with a torque rating of 330 lb⋅ft at 2,000 rpm. It was the largest displacement "performance" engine still available. Track testing in 1975 showed the 455 capable of 16.12 second quarter-mile time, which was similar to the L82 Corvette.1976
1976 saw a revision to the design and had done away with the rubber bumperettes on the front and back bumpers. Instead, the body featured a sleeker design with polyurethane front and rear bumpers that adhered to the safety standards at the time. The interior design was unchanged for the standard interior, however the deluxe interior seats had changed to feature larger and deeper buckets. The engine options across the Firebird remained the same as the previous year. This was the last year for the optional 15x7 honeycomb wheels. 1976 marked the end of the Pontiac L75 7.5L 455 V8, as it could no longer meet the tightening emissions restrictions and the "HO" moniker used the year prior was dropped. The L75 was only available with a four-speed manual Borg Warner Super T-10, and was exclusive to the Trans Am. 1976 also introduced the "W50 appearance package" for the Formula model line, consisting of a two-tone appearance package with lower accents across the bottom of the body, a large "Formula" decal across the bottom of each door, and a "Firebird" decal on the rear spoiler. The Formula had a one year exclusive steel hood design with smaller recessed, less pronounced hood snorkels. Pontiac celebrated its 50th anniversary year in 1976. To commemorate this event, Pontiac unveiled a special Trans Am option at the 19761977
The 1977 Firebird received a facelift that featured four rectangular headlamps. The shaker scoop was also revised for this year, with the early 1977-built T/As coming with off-center, lower-profile shaker scoops. The Formula hood was changed for the last time for the second generation with a much lower profile. The snowflake wheel became an option for all Firebirds and was standard with the Y82 appearance package, although it could be replaced with Rally II wheels as a credit option. For the Esprit, an optional appearance package RPO W60 called the "Skybird appearance package" became available, featuring an all blue exterior and interior. This package was originally slated to be called the "Bluebird" similar to the "Yellowbird" and "Redbird" packages to follow in the upcoming model years, but the name was already in use for a company that produced school buses. In 1977, General Motors began to source a larger selection of V8 engines to supply in the lower model Firebirds, and the Oldsmobile 350/403 V8, as well as the Chevrolet 305/350 V8, became options for the Firebird, Esprit, and Formula after June 1977. Previously, the Chevrolet inline-six was the only outsourced engine in a Firebird. Pontiac made the 301 (4.9 L) V8 available for order in the lower Firebird models, but due to such high demand and popularity, they removed it's availability from the Firebird model to allow enough 301 engines for the other Pontiac lines. It was re-introduced as an option in 1979 as production for the 400 ceased and tooling was converted over to the 301. The Trans Am had now three different engine options, the standard Pontiac L78 400, the optional extra cost Pontiac W72 400, and the Oldsmobile-sourced L80 403. 1977 also saw the cubic inch metrics on the shaker dropped in favor of the displacement of the cylinders. The shakers had a "6.6 Litre" decal for all L78 Pontiac 400 and L80 Oldsmobile 403 engines. Only the optional W72 Pontiac 400 received the "T/A 6.6" decal. As Pontiac had discontinued the 455 in the previous model year, a modified 400 Pontiac V8 dubbed the "T/A 6.6" RPO W72 with a single four-barrel 800CFM Rochester Quadrajet carburettor rated at at 3,600 rpm and a maximum1978
Changes for 1978 were slight, with a switch from a honeycomb to a crosshatch pattern grille being the most notable change to the body style. The decals for the standard Trans Ams changed from the "looping style" lettering to the "block-style" font that would remain on the Firebird until the end of the second generation. T-tops in 1978 transitioned from Hurst units to Fisher (GM) in mid-year. Pontiac also introduced the Red Bird package on the Firebird Esprit model. Painted in Roman red with a matching deluxe red interior, it demonstrated gold accents with a unique Red Bird graphic on the b-pillars. It also included a Formula steering wheel with gold spokes and gold dash bezel, similar to the ones included in the Special Edition package, however, the red and gold steering wheel was exclusive to the Red Bird Esprit. A new appearance package on offer for the Trans Am was the gold Y88 Special Appearance package, available for order in late 1977. It was a new variation of the black Y82 Special Appearance Package, and featured an all gold colour pallet, T-Tops, snowflake aluminium wheels, and the hood decal. All Y88's were painted in paint code 51 Solar Gold and always featured code 62 Camel Tan interior, however, the deluxe interior and tan coloured seatbelts were still pay extra options. The Y88 featured brown pinstriping as opposed to the gold pinstriping on the Y82/Y84 package, and included the new design 5-color hood decal and block style gold font callouts. The Y88 SE debuted the Fisher style T-Top roof and featured special gold tinted Fisher glass tops exclusive to the Y88. There are no confirmed documented examples of hard-top Y88's made. The Y88 was discontinued due to problems Pontiac experienced with the Solar Gold paint such as streaking in the paint, or a green discolouration with the water based paint used at the Van Nuys assembly plant. It was then changed back to the black Y84 (replaced RPO Y82) Special Appearance package for the very few remainder of the 1978 Special Edition Trans Ams built. The W72 engine option also saw a revision to the camshaft duration and the tuning of the Rochester Quadrajet which lead to a 10% increase of horsepower from the following year, bringing the total to 220 hp. Additionally, the earlier stronger and more durable 481988 cast block returned on the W72, denoted with a large "XX" cast protruding off the side of the block near the cast code. The WS6 special performance package developed by Herb Adams was introduced as a handling option for the Trans Am, including a larger diameter rear sway bar, tighter ratio steering box, 15x8-inch snowflake wheels, additional frame bracing, as well as other suspension changes. Delays in manufacturing prevented the rear disc brake (RPO J65) from being available on the 1978 model year. Approximately 23.1% (28,239) of Trans Ams in 1978 had the WS6 option according to Pontiac sales information at the start of 1979. At the end of 1978, the WS6 handling package became available for the Formula models as well.1979
The body was completely restyled for 1979, featuring a new aerodynamic front end, revised rear end spoiler, bulkier flares for the Trans Am, and a revised connected single taillight assembly design that would remain consistent for the rest of the Firebirds design. The grilles had been repositioned to the lower section of the front bumper to allow more cold air to directly travel to the lower part of the radiator and engine bay. The interior remained mostly unchanged to the previous model year, however the deluxe cloth interior had now changed from velour to a Hobnail pattern. The hood decal from the Y88 SE and Solar Gold cars from 1978 became the standard design across the entire Trans Am line and now came in a variety of colours. The Formula steering wheel that was optional in the lower models and standard in the Trans Am now came colour coded to the interior. For 1979, there were three possible engine options. The L80 Oldsmobile 403 engine became the standard option and was only available with the Turbo Hydramatic 350 3-speed automatic. The W72 Pontiac 400 was available for a short period and in limited supply. This was the last of the line for the Pontiac large displacement V8 engines, and only available with the Borg-Warner Super T-10, while also requiring the WS6 handling package as mandatory equipment in conjunction with this driveline choice. A credit option with a four-speed transmission was the smaller displacement L37 Pontiac 301 and it could come with either the Super T-10 or Turbo Hydramatic 350. The Formula received some revisions for the 1979, where the two-tone W50 colored stripe decal now became the standard look for the Formula, however, the W50 package was still available and it added the "Formula" lettering along the bottom of the doors and rear deck spoiler. The dashboard bezel now wore the same machined swirl aluminium bezel as the Trans Am. As the Pontiac 301 had now ramped up production as the Pontiac 400 production had ceased, it became the standard engine for the Formula. The WS6 package had now been renamed from the "Trans Am Mk IV Special Handling Package" to "Special Handling Package" as it was now available for the Firebird Formula. Due to significant popularity and demand for the option to receive 4 wheel disc brakes in the WS6 handling package, some WS6 equipped cars were shipped without the option of rear disc brakes and were instead coded WS7, but still received all other equipment included in the WS6 package. A limited-edition anniversary package to commemorate the 10th anniversary of the 1969 Firebird Trans Am was made available. It featured platinum silver paint with charcoal gray upper paint accents, mirrored T-tops, a special interior featuring silver leather seats with custom-embroidered Firebird emblems and aircraft-inspired red lighting for the gauges. The colloquially known as the "TATA" (Tenth Anniversary Trans Am, RPO Y89), it featured every single available production option on the Firebird, however, cruise control was not compatible with the manual transmission resulting in the being credited on the window sticker for the 4-speed equipped TATAs. The TATA also featured special 10th-anniversary decals, including a Firebird hood decal that extended off of the hood and onto the front fenders. Pontiac produced 7,500 Y89 TATAs, of which 1,817 were equipped with the high-output Pontiac T/A 6.6 W72 400 engine. The remainder all featured the Oldsmobile 403. Two TATAs were the actual pace cars for the 1979 Daytona 500, which has been called the race that made NASCAR. ''Car and Driver'' magazine named the Trans Am with the WS6 performance package the best handling car of 1979. During period dyno testing, the National Hot Rod Association rated the "T/A 6.6" W72 Pontiac 400 engine at 260–280 net horsepower, which was significantly higher than Pontiac's conservative rating of 220 hp. In 1979 Pontiac sold 116,535 Trans Ams, the highest sold in a year.1980
In 1980, ever-increasing emissions restrictions led Pontiac to drop all of its large-displacement engines. 1980 therefore saw the biggest engine changes for the Trans Am. The 301, offered in 1979 as a credit option, was now the standard engine. No manual transmission was available for the Firebird in 1980, all received the 3-speed automatic Turbo Hydramatic 350. Dealer order information listed a 3-speed manual available with the Buick V6 in the base model Firebird, however, none were ordered or built. Optional engines for the Trans Am and Formula included a turbocharged 301 or the Chevrolet 305 small block. The Chevrolet LG4 305 was mandatory in Californian and High Altitude emission states. There were three different iterations of the 301 in 1980, the L37 301 4bbl, the W72 E/C 301 T/A 4.9, and the LU8 301 Turbo. The W72 E/C 301 was standard for the Trans Am and optional for the Formula, however the W72 E/C could be deleted and instead come equipped with the standard L37 301. The turbocharged 301 used a Garrett TB305 turbo attached to a single Rochester Quadrajet four-barrel carburetor and featured a hood-mounted "boost" gauge that would light up as the TB305 accumulated boost. The hood of the 301T equipped Firebirds had a large offset bulge to accommodate for the mounting position of the carburetor on the engine as the turbocharger exhaust occupied a large amount of space in the engine bay. The 301T equipped cars were restricted to an automatic transmission, a 3.08 rear differential ratio and were always required to have A/C. A memo from Pontiac to dealers in late 1980 mandated that all 301T cars must be ordered with J65 rear disc brakes or the orders would be rejected. However, the WS6 Special Handling Package was never mandatory with the 301 Turbo. The Redbird Esprit was retired for 1980, and the new Yellowbird Esprit was introduced. This was the last year to feature the colored Esprit appearance packages. It featured a two-tone yellow exterior with yellow 15x7 snowflake wheels, deluxe Camel Tan interior, a gold dash bezel, special yellow Firebird decals, and Formula steering wheel. The new Limited Edition Trans Am produced for 1980 was the Y85 Turbo Trans Am Pace Car that was featured in the1981
1981 became the final year for the second generation Pontiac Firebird. The three engine options were unchanged for the model line-up, however, the option for a four-speed Borg Warner Super T-10 was re-introduced for the Formula and Trans Am, but was only available with the Chevrolet sourced LG4 305 "5.0 LITRE" V8. The W72 E/C 301 replaced the standard 301, so the W72 code was dropped as all 301 engines featured the Electronic Spark Control system. The 301T now became certified to pass Californian and H/A emissions requirements, making it the most powerful Pontiac engine to be sold in California since the mid 70's. As with all other General Motors vehicles for 1981, all engines came equipped with the "computer command control" system attached to the carburetor. The hood decal for the 1981 model year was also slightly restyled. All Firebirds also received an embossed silver Firebird decal on the petrol tank cap attached to the rear taillights. On the special edition Trans Ams, this Firebird was gold. The Turbo wheel previously exclusive to the 301 Turbo cars now became available across the Esprit and Formula line in a slightly smaller size (15x7.5" as opposed to the WS6 Formula/Trans Am 15x8") The Formula received some changes for the 1981 model year, as previously in 1979, the two-tone W50 style paint was standard without the Formula lettering. However, if the W50 package was not ordered, the Formula simply appeared in the single colour they were ordered in with the smaller fender decals. This also prompted an increase in price for the W50 option as the decals were not included in the base Formula package anymore. In mid 1981, theEngines

Third generation (1982–1992)
The availability and cost of gasoline (two fuel crises had occurred by this time) meant the weight and the fuel consumption of the third generation had to be considered in the design. In F-body development, both the third generation Firebird and Camaro were proposed as possible front-wheel-drive platforms, but the idea was scrapped. Computerized engine management was in its infancy, and with fuel efficiency being the primary objective, it was not possible to have high horsepower and torque numbers. They did manage to cut enough weight from the design so that acceleration performance would be better than the 1981 models. They also succeeded in reducing fuel consumption, offering a four-cylinder Firebird that would provide . GM executives decided that engineering effort would best be spent on aerodynamics and chassis development. They created a modern platform so that when engine technology advanced, they would have a well-balanced package with acceleration, braking, handling, and aerodynamics. The Firebird and Camaro were completely redesigned for the 1982 model year, with the windshield slope set at 62 degrees, (about three degrees steeper than anything GM had ever tried before), and for the first time, a large, glass-dominated hatchback that required no metal structure to support it. Two concealed pop-up headlights, a first on the F-Body cars, were the primary characteristic that distinguished the third generation Firebird from both its Camaro sibling and its prior form (a styling characteristic carried into the fourth generation's design). In addition to being about lighter than the previous design, the new design was the most aerodynamic product GM had ever released. Wind tunnels were used to form the new F-Body platform's shape, and Pontiac took full advantage of it. The aerodynamic developments extended to the finned aluminum wheels with smooth hubcaps and a functional rear spoiler.Models

In 1988 the Trans Am GTA, which was built with the standard 350 cu in 5.7 L V8 engine, was offered with the option of the removable roof "T-tops". However, any buyer ordering this option could only order the 305 cu in 5.0 L V8 engine, because the roof did not have the support for all the extra torque from the engine, requiring a power trade-off for those who wanted this option. Pontiac also introduced a rare option for the Trans Am GTA in the 1988 model year, the $800 "notchback", which replaced the standard long large, glass-dominated hatchback to make the Firebird design look less like the Camaro design, and shared an appearance with theEngines
Fourth generation (1993–2002)
The fourth-generation Firebird amplified the aerodynamic styling initiated by the previous generation. While the live rear axle and floorpan aft of the front seats remained largely the same, ninety percent of the Firebird's parts were all-new. Overall, the styling of the Firebird more strongly reflected the Banshee IV concept car than the 1991 "facelift" did. As with the Camaro, major improvements included standard dual airbags, four-wheel anti-lock brakes, 16-inch wheels, rack-and-pinion power steering, short/long-arm front suspension, and several non-rusting composite body panels. Throughout its fourth generation, trim levels included V6-powered Firebird, and V8-powered Formula and Trans Am. Standard manual transmissions were the T5 five-speed manual for the V6s, Borg-Warner′s T56 six-speed manual for the V8s. The 4L60 four-speed automatic was optional for both in 1993, becoming the 4L60E with built-in electronic controls in 1994.1993–1997
From 1993 until 1995 (1995 non-California cars), Firebirds received a 3.4 L V6, an enhanced version of the third-generation's 3.1 L V6. Beginning mid-year 1995 onward, a Series II 3.8 L V6 with became the Firebird's sole engine. From 1993 until 1997, the sole engine for the Formula and Trans Am was the 5.7 L LT1 V8, essentially identical to the LT1 in the C4 Corvette except for more flow-restrictive intake and exhaust systems. Steering wheel audio controls were included with optional uplevel cassette or compact disc stereo systems. Beginning with 1994 model year cars, "Delco 2001"-series stereo systems replaced the previous Delco units. This revised series, also introduced for other Pontiac car lines, featured ergonomically-designed control panels with larger buttons and an optional seven-band graphic equalizer. Also in 1994, the fourth-generation convertible was available; every Firebird (and Camaro) convertible featured a glass rear window with a built-in electric defroster. The 1995 models were the same as those of previous years, but traction control (ASR: acceleration slip regulation) was available for LT1 Firebirds, controlled by a switch on the console. The steering wheels in all Firebirds were also changed; their optional built-in audio controls were more closely grouped on each side. The "Trans Am GT" trim level was dropped from the lineup after its model year run in 1994. For 1995, all Trans Ams received 155-mph speedometers and Z-rated tires. 1995 was also the first year of the vented version of the Opti-Spark distributors on LT1 F-cars, addressing a common mechanical fault with the unit. The 'transmission perform' button was available only in the 1994 and 1995 Formula and Trans Am. This option was stopped for the 1996 and later models, but the unused connections remain available for 1996 and 1997 Formula and Trans Am. While 1995 cars still used the OBD-I (on-board diagnostic) computer system (the last year of any American car including the F-body to use OBD-I), a majority of them had OBD-II connector ports under the dash. Firebird performance levels improved for 1996, with the establishment of the stronger 200-hp 3.8 L V6 as the new base engine, and the power rating of the LT1 increased to 285 for 1996, due to its new dual catalytic-converter exhaust system. 1996 was also the first model year of the OBD-II computer system. Optional performance enhancements were available for each Firebird trim level; the Y87 performance packages for V6s added mechanical features of the V8 setups, such as four-wheel disc brakes, faster-response steering, limited-slip rear differential, and dual tailpipes. For Formulas and Trans Ams, functional dual-inlet "Ram Air" hoods returned as part of the WS6 performance package. The optional package boosted rated horsepower from 285 to 305, and torque from 325 lb·ft to 335. Also included were 17x9-inch wheels with 275/40ZR17 tires, suspension improvements, oval dual tailpipe tips, and a WS6 badge. Bilstein shocks were a further option with the package. The 1997 model year introduced standard air conditioning, daytime running lamps (utilizing the front turn signal lamps), digital odometer and optional 500-watt Monsoon cassette or compact disc stereo systems to all Firebird trim levels. For V6 Firebirds, a W68 sport appearance package was also introduced as a counterpart to the Camaro RS trim level. The WS6 "Ram Air" performance package was now also an option for the Formula and Trans Am convertibles, although these convertibles did not receive the 17-inch wheel-and-tire combination. There were 41 Formula convertibles and 463 Trans Am convertibles produced from 1996 until 1997 with the WS6 package.1998–2002
In 1997, in relation to the Camaro, the Firebird received a mid-cycle refresh for the 1998 model year. Major changes included a new hood and front fascia with dual intakes, retracting quad halogen headlights, circular turn signals and fog lamps, a front license plate pocket, lower fender air vents, unified-style lower door raised lettering for each trim level, and a new "honeycomb" rear light panel, with circular reverse lamps. In the dashboard, "next-generation" reduced-force dual airbags became standard. As before, the Formula and Trans Am again received a close derivative of the Corvette's 5.7 L V8, the LS1 of the C5 Corvette, as the LT1 (and LT4) V8s were discontinued. The LS1 Firebirds were also equipped with an aluminum driveshaft, replacing the previous steel version, while all Firebird trim levels gained four-wheel disc brakes with dual-piston front calipers and larger rotors at each wheel, complete with a solenoid-based Bosch anti-lock system. The Formula convertible was no longer offered. Beginning in 1998 for 1999 models, a standard 16.8-gallon non-metallic fuel tank increased the potential traveling range. GM's ASR traction control system was extended to the V6-powered Firebirds, and all LS1 (V8) and Y87 (V6) Firebirds also received a Zexel/Torsen II slip-reduction rear axle. An electronic brakeforce distribution (EBD) system replaced the old hydraulic proportioning valve for improved brake performance. An enhanced sensing and diagnostic module (SDM) recorded vehicle speed, engine rpm, throttle position, and brake use in the last five seconds prior to airbag deployment. In 1999, aSpecial editions
Firehawk
The special-edition extra-performance Firehawk (available in Formula trim for 1993–1997, and again in both Formula and Trans Am trims for 1999–2002) was produced by SLP Engineering, Inc., and sold through Pontiac dealerships. Featuring 17-inch wheels with namesake Firestone Firehawk 275/40ZR17 tires along with a functional twin-inlet hood above a specific air cleaner box, its rated power increased to and 330 lb·ft (445 Nm) of torque. A total of 201 Firehawks were built for 1993. In 1994, the Firehawk package was expanded to include options for a suspension upgrade as well as a larger-diameter exhaust system that could boost power to . T-top Formula coupes and convertibles could also be optioned as Firehawks beginning in 1995. For 1996 and 1997, the Firehawk gained rectangular driving lights mounted inside the front scoops and (except Firehawk convertibles) the Trans Am's elevated rear wing. In 1997, an LT4 Firehawk was also available, utilizing the same , balanced-and-blueprinted LT4 V8 engine as found in the manual-transmission 1996 Corvette. A total of 29 LT4-powered Firehawks were produced. Power levels for the 1999 Firehawk, powered by the LS1 V8, rose to (330 in 2000, 335 in 2001, and 345 in late 2002 models equipped with the "Blackwing" intake). A 10th-anniversary Firehawk was available in 2001, distinguished as a black Trans Am coupe (123 units) and convertible (16 units) with gold-painted hood stripes (prototype only), gold vinyl stripes on hood and spoiler (production), gold 17-inch wheels, and gold tailpipe tips.1994 Trans Am GT
In 1994 only, a "Trans Am GT" option was available. Trans Am GTs did not receive any special badging, graphics, or emblems, and looked externally identical to the base Trans Am cars. The GT package included 245/50ZR16 tires and a 155-mph speedometer. Non-GT optioned Trans Ams in 1994 received 235/55R16 tires, a 115-mph speedometer, and a much lower top-speed limiter. The "highrise spoiler", leather, and T-tops were not standard on the Trans Am GT cars in 1994, nor any year of LT1 Trans Am. RPO code T43 "uplevel spoiler" was an option on all Trans Ams, and while the mass majority of 1994 Trans Am GT cars received the T43 spoiler (along with the majority of all 1993–1997 Trans Ams), it was not part of the Trans Am GT package. Both base Trans Ams and Trans am GTs could be ordered as a coupe, T-top, or convertible versions and were both available with automatic or manual transmissions. While the GT package was a cost option on the 1994 Trans Am, a majority of 1994 Trans Ams were made with the GT package. All of the 1994 Trans Am GT options became standard in 1995–2002 as part of the Trans Am package, and the GT name/package was dropped for 1995. Some of the early fourth-generation Trans Am and Formula Firebirds list "GT" on the vehicle's title or registration. The reason behind this is because the VIN does not specify a "package" (Formula, Trans Am, Trans Am GT, Firehawk, etc.); it only specifies the engine (5.7 L V8 LT1). Because the title is based on the VIN alone, titles and registrations often list all of the packages, but it does not mean the car is equipped with any certain package.1994 25th-anniversary Trans Am
The 1994 model year marked the 25th anniversary of the Trans Am, and another anniversary edition was released, painted white with a single dark blue stripe down the center of the vehicle that was reminiscent of the 1970 Trans Am. It also featured white-painted, five-spoke, 16-inch alloy wheels, and white leather seats and door trim. This edition was available in either coupe, T-top or convertible form.1999 30th-anniversary Trans Am
As with the previous 25th-anniversary edition, the 30th-anniversary edition was either a white WS6 convertible or WS6 T-top coupe, with twin dark blue stripes from hood to tail, and distinct blue anodized five-spoke 17-inch alloy A-mold wheels, with white leather seats and door trim. 2001 was the 75th anniversary of Pontiac. A 75th-anniversary package incorporated a power and performance package that included power door locks including retained accessory power, power windows including express down drivers side, dual power sport mirrors, power antenna. Radio, ETR AM/FM stereo with CD player and 7-band graphic equalizer including a clock, seek up/down, remote CD pre-wiring Monsoon 500 watt peak power with 10-speaker premium sound system and steering wheel leather-wrapped w/driver touch radio controls. 4-speed automatic transmission, power drivers 6-way seat, security package (includes theft-deterrent system and remote key-less entry), 3800 performance package that included 3.42 gears with "posi-trac" Zexel Torsen T2 limited-slip differential, 4-wheel disc brakes, dual mufflers, and an LS1 steering rack= 14.4:1, 235/55/16 tires, hatch roof, removable, 16-inch chromed aluminum wheels, 50-state low emission vehicle. There were a total of 472 of these packages sold in 2001, No. 239 on the L36 Firebird, 231 on the Formula W66 coupe, 5 on Formula Firehawks, and 2 on Trans-Ams. The manufacturer original window stickers included this as a separate package listing the items and one price.2002 collector's edition Trans Am
For the Firebird's final year, a collector's edition Trans Am was released as either a yellow WS6 convertible or WS6 T-top coupe, with twin black stripes from hood to tail, black-painted five-spoke 17-inch alloy wheels, and further black-trimmed body details.Engines
