    Pontiac Firebird (4th gen) 1993-2002

    The Pontiac Firebird was an American automobile built by Pontiac from the 1967 to 2002 model years. Designed as a pony car to compete with the Ford Mustang and Mercury Cougar, it was introduced on February 23, 1967, simultaneous with GM's Chevrolet division platform-sharing Camaro. This also coincided with the release of the 1967 Mercury Cougar, Ford's upscale, platform-sharing version of the Mustang.

    The name "Firebird" was also previously used by GM for the General Motors Firebird 1950s and early 1960s concept cars.

    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 160 hp (119 kW) 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 200 hp (149 kW) became the Firebird's sole engine. From 1993 to 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.[29]:898 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 was 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 17" x 9" 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 turnsignal lamps), digital odometers, 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 to 1997 with the WS6 package.

    1998-2002
    In 1997, in relation to the Camaro, the Firebird received a mid-cycle refresh for 1998 model year. Major changes included a new hood and front fascia with dual intakes, retracting quad halogen headlights, circular turnsignal 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.[29]:911 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 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, a Hurst shifter for variants with the 6-speed manual and a power steering cooler became options for LS1 Firebirds.

    In 2000, the WS6 performance package was available exclusively for 2001 model year Trans Am coupe and convertible variants.

    For 2002, more convenience items such as power mirrors and power antenna became standard equipment, while cassette stereos were phased out.
