Ford Thunderbird


Ford Thunderbird is a nameplate that was used by Ford from model years 1955 to 1997 and 2002 to 2005 for a personal luxury car during which there were eleven distinct generations. Introduced as a two-seat convertible, the Thunderbird was produced in a variety of body configurations. These included a four-seat hardtop coupe, four-seat convertible, five-seat convertible and hardtop, four-door pillared hardtop sedan, six-passenger hardtop coupe, and five passenger pillared coupe, with the final generation designed again as a two-seat convertible.
Ford targeted the two-seat Thunderbird as an upscale model, but the design introduced for 1958 featured a rear seat and arguably marked expansion of a market segment eventually known as personal luxury cars. An American interpretation of the grand tourer, personal luxury cars were built with a higher emphasis on driving comfort and convenience features over handling and high-speed performance. From 1968 to 1998, Lincoln-Mercury marketed rebadged variants of the Thunderbird as the Continental Mark III, Mark IV, Mark V, Mercury Cougar, Lincoln Mark VII, and Lincoln Mark VIII.

Overview

The Thunderbird entered production for the 1955 model year as a sporty two-seat convertible. Unlike the Chevrolet Corvette, it was not marketed as a sports car. Ford positioned the Thunderbird as an upscale model and it is credited in developing a new market segment, the personal luxury car. For 1958, the Thunderbird was redesigned with a second row of seats. Succeeding generations became larger until the line was downsized in 1977, again in 1980, and once again in 1983. Sales were good until the 1990s, when large 2-door coupes became unpopular. Initial production ceased at the end of 1997. In 2002, production of the Thunderbird started again; a revived 2-seat model was launched which was available through the end of the 2005 model year. From its introduction in 1955 to its final phaseout in 2005, Ford produced over 4.4 million Thunderbirds.

Convertible models

The Second to Fourth Generation Thunderbird convertibles were similar in design to the Lincoln convertible of the time and utilized a design from earlier Ford hardtop and convertible models. While these Thunderbird models had a true convertible soft top, the top was lowered to stow in the trunk. This design reduced available trunk space when the top was down.
The trunk lid was rear-hinged; raised and lowered via hydraulic cylinders during the top raising or lowering cycle. The forward end of the trunk lid contained a metal plate that extended upward to cover the area that the top is stowed in. With the top down and the trunk lid lowered, there is no sight of the soft top. With the top down, the overall appearance had no trace of a convertible top and no separate cover boot was needed.
However, this design could present a challenge to one who is troubleshooting a convertible top malfunction. The system consists of a spiderweb of solenoids, relays, limit switches, electric motors, a hydraulic pump/reservoir, hydraulic directional valves and cylinders. While the hydraulics are not often a cause for trouble, the electrical relays are known to fail. Failure of any of the relays, motors or limit switches will prevent the convertible system from completing the cycle.
Unlike hardtop models that utilized a conventional key-secured, forward hinged design, the convertibles combined the trunk opening and closing within the convertible top operating system.

Genesis

A smaller two-seater sports roadster was developed at the behest of Henry Ford II in 1953 called the Vega. The completed one-off generated interest at the time, but had meager power, European looks, and a correspondingly high cost, so it never proceeded to production. The Thunderbird was similar in concept, but would be more American in style, more luxurious, and less sport-oriented.
Credit for the development of the original Thunderbird is given to Lewis Crusoe, a former GM executive lured out of retirement by Henry Ford II; George Walker, chief stylist and a Ford vice-president; Frank Hershey, chief stylist for Ford Division; Bill Boyer, designer Body Development Studio who became manager of Thunderbird Studio in spring of 1955; and Bill Burnett, chief engineer. Ford Designer William P. Boyer was lead stylist on the original 1955 two-seater Thunderbird and also had input in following series of Thunderbirds including the 30th Anniversary Edition. Hershey's participation in the creation of the Thunderbird was more administrative than artistic.
Walker promptly telephoned Ford's HQ in Dearborn and told designer Frank Hershey about the conversation with Crusoe. Hershey took the idea and began working on the vehicle. The concept was for a two-passenger open car, with a target weight of, an Interceptor V8 engine based on the forthcoming overhead-valve Ford V8 slated for 1954 model year introduction, and a top speed of over. Crusoe saw a painted clay model on May 18, 1953, which corresponded closely to the final car; he gave the car the go-ahead in September after comparing it with current European trends. After Henry Ford II returned from the Los Angeles Auto Show in 1953, he approved the final design concept to compete with the then new Corvette.
The name was not among the thousands proposed, including rejected options such as Apache, Falcon, Eagle, Tropicale, Hawaiian, and Thunderbolt. A Ford stylist who had lived in the southwest submitted the Thunderbird name. The word "thunderbird" is a reference to a legendary creature for North American indigenous people. It is considered a supernatural bird of power and strength.
Thunderbird Country Club in Rancho Mirage, California also lays claim to being the inspiration for the name of the car. Ernest Breech, a Thunderbird Country Club member, who was then chairman of Ford Motor Company was supposedly deeply involved in the creation of the Thunderbird. Breech asked the Club's permission to name the new model after the Club and the club consented to the use of the name.

Generations

First generation (1955–1957)

The Ford Thunderbird was introduced in February 1953 as response to Chevrolet's new sports car, the Corvette, which was publicly unveiled in prototype form just a month before. Under rapid development, the Thunderbird went from idea to prototype in about a year, being unveiled to the public at the Detroit Auto Show on February 20, 1954. It was a two-seat design available with a detachable glass-fibre hard top and a folding fabric top. Production of the Thunderbird began on September 9 of that year, with the car beginning sales as a 1955 model on October 22, 1954. Though sharing some design characteristics with other Fords of the time, such as single, circular headlamps and tail lamps and modest tailfins, the Thunderbird was sleeker in shape, and featured a hood scoop and a speedometer not available on other Fords. It utilized mechanical components from mass-market Ford models. The Thunderbird's wheelbase frame was a shortened version used in other Fords and the standard Y-block V8 came from Ford's Mercury division.
Though inspired by, and positioned directly against, the Corvette, Ford billed the Thunderbird as a personal car, putting a greater emphasis on the car's comfort and convenience features rather than its inherent sportiness. The Thunderbird sold exceptionally well in its first year. In fact, the Thunderbird outsold the Corvette by more than 23-to-one for 1955 with 16,155 Thunderbirds sold against 700 Corvettes. With the Thunderbird considered a success, few changes were made to the car for the 1956 model year. The most notable change was moving the spare tire to a continental-style rear bumper in order to make more storage room in the trunk and a new 12 volt electrical system. The addition of the weight at the rear caused steering issues. Among the few other changes were new paint colors, the addition of circular porthole windows as standard in the fiberglass roof to improve rearward visibility, and a Y-block V8 rated at when mated to a 3-speed manual transmission or when mated to a Ford-O-Matic 2-speed automatic transmission; this transmission featured a "low gear", which was accessible only via the gear selector. When in "Drive", it was a 2-speed automatic transmission. The Low gear could also be accessed with wide open throttle.
The Thunderbird was revised for 1957 with a reshaped front bumper, a larger grille and tailfins, and larger tail lamps. The instrument panel was heavily re-styled with round gauges in a single pod, and the rear of the car was lengthened, allowing the spare tire to be positioned back in the trunk. The V8 became the Thunderbird's standard engine, and was now rated at. Other, more powerful versions of the V8 were available including one with two four-barrel Holley carburetors and another with a Paxton supercharger rated at. Though Ford was pleased to see sales of the Thunderbird rise to a record-breaking 21,380 units for 1957, company executives felt the car could do even better, leading to a substantial redesign of the car for 1958.

Second generation (1958–1960)

Although the 1955–57 Thunderbird was a success, Ford executives—particularly Robert McNamara—were concerned that the car's position as a two-seater limited its sales potential. As a result, the car was redesigned as a four-seater for 1958.
The new Thunderbird began a sales momentum previously unseen with the car, selling 200,000 units in three years, four times the result of the two seat model. This success spawned a new market segment, the personal luxury car. It was the first individual model line to earn Motor Trend "Car of the Year" honors.
It was offered in both hardtop and convertible body styles, although the latter was not introduced until June 1958, five months after the release of the hardtop. The new Thunderbird was considerably larger than the previous generation, with a longer wheelbase to accommodate the new back seat. The increased size also increased the car's weight by. Along with a new, more rigid unibody construction was new styling, including quad headlights, more prominent tailfins, a bolder chrome grille, and a larger, though non-functional, hood scoop. Powering the Thunderbird was a new, FE V8, available with a three-speed manual or automatic transmissions.
In the 1958 model year in which the car was introduced, sales were 37,892 units, outselling the previous model year's 16,000 units.
For 1959, the car received a new grille and a newly optional, MEL V8 for 1959, sales climbed even higher to 67,456 units.
For 1960, the Thunderbird was given another new grille and other minor styling changes along with a newly optional manually operated sunroof for hardtop models. Dual-unit round taillights from 1958 to 1959 were changed to triple-units after the fashion of the Chevrolet Impala. Sales increased again with 92,843 sold for 1960.

Third generation (1961–1963)

The Thunderbird was redesigned for 1961 with styling that gave the car a unique bullet-like body side appearance. A new engine, the FE V8, was the standard and only engine initially offered in the Thunderbird. It was rated at and was mated to a 3-speed automatic transmission. The new Thunderbird was well received with 73,051 sold for 1961.
The car was 1961's Indianapolis 500 pace car and was featured prominently in US President John F. Kennedy's inaugural parade, who appointed Ford executive Robert McNamara as Secretary of Defense. It also benefitted from product placement, notably on the popular television series 77 Sunset Strip.
A vinyl-roofed Landau option with simulated S-bars was added to the Thunderbird for 1962 as was a Sports Roadster package for convertible models. The Sports Roadster included 48-spoke Kelsey-Hayes designed wire wheels and a special fiberglass tonneau cover for the rear seats which gave the car the appearance of a two-seat roadster like the original Thunderbird. The Sports Roadster package was slow-selling due to the high price of the package and complexity of the tonneau cover, resulting in few Thunderbirds being equipped with it. Newly optional for 1962 was an upgraded version of the V8 called the "M-Code". The M-Code version of the V8 was equipped with three two-barrel Holley carburetors and was rated at. M-Code V8 Thunderbirds are exceptionally rare with only 200 being sold between 1962 and 1963. For 1963 only, Y-code cars could come equipped with the same 390 cubic inch V8 also equipped by the factory with tri-power carburetors only if the buyer desired air conditioning.
Few other changes were made to the Thunderbird for 1963 as Ford prepared to introduce a new version for 1964. A horizontal styling line was added that ran from the point where bumper and fender meet back through the door and angled down. Small diagonal chrome bars were added in this area on the door. Alternators rather than generators were a new feature on all 1963 Thunderbirds.

Fourth generation (1964–1966)

For 1964 the Thunderbird was restyled in favor of a more squared-off appearance, which was mostly evident when viewing the car from the side or rear. Hinting at its roots in the previous generation of Thunderbird that it evolved from, the new model retained a similar grille design with quad headlights and a wheelbase. As before, the new Thunderbird continued to be offered in hardtop, convertible, and Landau versions. The FE V8 continued as the standard engine for the Thunderbird. It was paired with a 3-speed automatic transmission. For 1965, sequential turn signals were added, flashing the individual segments of the broad, horizontal tail lights in sequences from inside to outside to indicate a turn. Also new for 1965 were standard front disc brakes, and doubled sided keys.
Even though it was the last year of the generation, 1966 saw a stylistic revision for the Thunderbird highlighted by a new egg-crate style grille with a large Thunderbird emblem at its center and a single-blade front bumper. The rear bumper was restyled to include new full-width taillamps. Engine choices were also revised for 1966. The standard V8 equipped with a single four-barrel carburetor was rated at. Newly optional and taking the top position for performance was a FE V8. The 428 cost only $86 over the base engine, and was a popular option. This would be the last year for the convertible until the "retro" models of 2002-05.

Fifth generation (1967–1971)

; 1967–1969
The Thunderbird's fifth generation brought the second major change in the car's design direction since its debut in 1955. From 1958 to 1966, the Thunderbird had remained fundamentally the same in concept as a sporty two-door coupe/convertible with two rows of seating. However, the introduction of the Ford Mustang in early 1964 had created a challenge to the Thunderbird's market positioning for it. Like the Thunderbird, the Mustang was also a two-door coupe/convertible with two rows of seating. Where the Mustang had an advantage was in the point that it was substantially cheaper. To prevent overlap between the two cars, Ford's response was to move the Thunderbird upmarket. The result, introduced for 1967, was a larger Thunderbird with luxury appointments more in line with a Lincoln.
The new Thunderbird abandoned unibody construction in favor of a body-on-frame construction with sophisticated rubber mountings between the body and frame to reduce noise and vibration. A pair of significant departures from the previous generation of the Thunderbird was the elimination of a convertible model and the addition of a four-door model, which used suicide doors for rear seat access. The available four-door design would remain a unique feature to this generation as it was not carried on after 1971. One of the most noticeable design elements of the fifth generation Thunderbird was the gaping, fighter jet-inspired grille opening that incorporated hidden headlights.
; 1970–1971
The 1970 Thunderbird continued with the same platform and many of the same parts and styling cues used in the 1967 to 1969 models, including the sequential turn signals incorporated into the full width tail lamps. The most noticeable change was in the front fascia where there was now a large prominent projection resembling a bird or eagle's beak that was in line with long angular lines in the hood. Semon "Bunkie" Knudsen, a former GM executive now President of Ford, is said to be responsible for this dramatic change. The T-bird was offered in coupe or sports-back models for these two years, the latter being a further distinction from the '67 to '69 models.
In 1971, Neiman Marcus offered "his and hers" Thunderbirds in its 1970 catalog, with telephones, tape recorders and other niceties. Sold only as a pair, they retailed for a total of $25,000 USD. The 1971 Thunderbird was mostly a carry-over from the 1970 model as Ford prepared to release a new, larger Thunderbird for 1972. It was also the last year to offer a four-door.

Sixth generation (1972–1976)

The sixth generation of the Thunderbird debuted in the fall of 1971 as a 1972 model. With a wheelbase, an overall length of , and a curb weight of , it was the largest Thunderbird ever produced by Ford, sharing the assembly line with the Lincoln Continental Mark IV. Matching the large size of the car were large engines, including a standard V8 and an optional V8. Though offering two of the largest displacement V8 engines ever installed in a production vehicle by Ford, the car's considerable weight combined with low power output caused by restrictive emissions technology resulted in modest performance. As might also be expected from installing a large displacement V8 in a heavy car, fuel efficiency was poor. The big Thunderbirds were popular with sales peaking at over 87,000 units in 1973 in spite of the 1973 oil crisis, but sales had slumped to less than 43,000 by 1975. Finishing off the generation, sales saw an uptick to almost 53,000 units for 1976. Acknowledging increasing fuel prices and more stringent federal emissions standards, a new, down-sized Thunderbird would appear for 1977.

Seventh generation (1977–1979)

For the 1977 model year, the Thunderbird was shifted to the smaller wheelbase chassis that underpinned the 1972–76 Ford Torino and its replacement, the LTD II which also debuted for 1977. Even with the nearly 8 inches shorter length from the 1975 Thunderbird it still looked large to the eye. It was not until the next generation that there was a dramatic downsizing, from 217.7 to 200.4 inches in length. 1977 saw Ford's first effort at downsizing the Thunderbird, reflecting rising demand for more fuel efficient cars. In essence, this generation was a continuation of the 1974–1976 Ford Elite, Ford's first attempt at competing in the market created by the Pontiac Grand Prix and Chevrolet Monte Carlo. Compared to the previous generation Thunderbird, the new car lost nearly 8 inches of overall length at 217.7 and of weight, although height and width were relatively unchanged. A substantial component of the weight reduction was in the drivetrain, where a small-block V8 replaced the heavier big-block V8s of previous years and proved to be an outstanding performer. The standard engine outside California was the Windsor V8, while the larger 351M and Ford 335 engine| and T-tops were available as options along with the 351W. In California, the 351 was the standard engine, and the 400 was optionally available. For the first time, a wide fixed "B" pillar was used, reflecting Detroit's abandonment of pillarless hardtops in the mid- and late-1970s. However, the door window glass remained frameless.
In 1978, Ford offered the "Diamond Jubilee Edition" Thunderbird to commemorate the company's 75th year as an auto manufacturer. This option package escalated the price of the car to almost US$12,000, virtually doubling the standard price. Naturally, it included every option available except for a moonroof and an engine block heater. A similar option package, called "Heritage", was available for 1979. Though this generation was the most successful in sales with over 955,000 examples produced in its three-year run, Ford sought to downsize the Thunderbird further out of fuel efficiency and emissions concerns, leading to a redesign for 1980. For the 1979 model year, the 400 cuin engine was no longer available.

Eighth generation (1980–1982)

Reflecting a further industry-wide adoption of smaller vehicle designs in the interest of improved fuel efficiency and emissions compliance, the Thunderbird was redesigned for 1980 on the compact Ford Fox platform, which first appeared only two years prior as the basis for the Ford Fairmont. Compared to the previous Torino-based Thunderbird and its large wheelbase and overall length, the new Thunderbird lost of wheelbase and in overall length. The squarish styling seen in the previous generation of the Thunderbird was favored for the new model, but now utilizing a smaller car platform. Frameless door glass was no longer used; a chrome metal frame was used instead, making the car look more like a two-door sedan. Combined with the poor performing Windsor V8 as a base engine, and a C5 3 speed transmission with 2.26 rear gears, this Thunderbird generation was not well received by the public. The available 5.0 L Windsor V8 with the AOD automatic overdrive transmission, coupled with a 3.45 rear end gear, was a welcome alternative to the 255, but with only, performance was moderately enhanced. Significantly, though failing to generate any new interest for the Thunderbird, a six-cylinder engine was made available for the first time in the Thunderbird's history in 1981, the Thriftpower Six. For 1982 this was followed up with the replacement of the straight-six with a more modern V6, the 3.8 L Essex, which was also now the Thunderbird's standard engine. It came equipped with a Motorcraft 2150 2V carburator. Hurting the Thunderbird's sales performance further, the 302 V8 did not return for 1982, leaving the 255 Cubic inch V8 as the only alternative engine. At 288,638 examples produced between 1980 and 1982, the eighth generation of the Thunderbird was barely more successful than the final model year of the previous Thunderbird generation.

Ninth generation (1983–1988)

In response to the lackluster reception of the eighth-generation 1980–1982 Thunderbird, Ford executed a significant redesign for 1983. Though based on the Fox body like the previous Thunderbird, the new Thunderbird featured a radically sleeker, more aerodynamic body and a slightly shorter wheelbase of. To power the new Thunderbird, the 3.8 L Essex V6 and the 5.0 L V8 were carried over from the previous generation with the V8 engine gaining CFI electronic fuel injection in 1983, and the V6 in 1984 for US models, 1985 for Canadian models. All-new, and a Thunderbird first, was a turbocharged 2.3 L OHC 4-cylinder engine featured in the 1983 Thunderbird Turbo Coupe. The engine initially was rated at, but by 1985 power was increased to. Another first was the availability of a 5-speed manual transmission with the turbocharged four. In 1983, the higher trim model was the Heritage; this was renamed the Elan in 1984. There was also a Fila-branded model. In 1985, a special 30th Anniversary edition was available, with special Medium Regatta Blue Metallic paint, special graphics, and trim.
For 1987 the Thunderbird received a significant refresh complete with new sheetmetal and a revised front fascia with aerodynamic composite headlamps. Mechanically the car was mostly unchanged. V6s models carried over port fuel injection from 1986 while the Turbo Coupe's turbocharged 4-cylinder engine gained an intercooler, increasing output to and 240 lbs of torque.

Tenth generation (1989–1997)

On December 26, 1988, a completely redesigned Thunderbird was introduced as a 1989 model along with the similar Mercury Cougar. The new Thunderbird was developed on Ford's MN12 platform, which had been in development since 1984. Featuring a nine-inch longer wheelbase than the previous generation Thunderbird and a four-wheel independent suspension, with short-and-long arms and a spring strut assembly in the front and multiple links in the rear, the car offered excellent handling and ride quality. Significantly, the 1989 Thunderbird was the first in the car's history not to offer a V8 engine, instead offering two different versions of Ford's 3.8 L Essex OHV V6. Standard versions of the Thunderbird received a naturally aspirated version of the V6 producing while the model received a supercharged and intercooled version of the engine rated at. The naturally aspirated V6 came with an AOD 4-speed automatic transmission as standard equipment. The AOD was optional on the Super Coupe and a M5R2 5-speed, Mazda-derived manual transmission was standard in the SC model.
The Super Coupe's engine had the same displacement as the naturally aspirated V6, but most all internal components were upgraded to handle the increased torque and temperature generated due to the addition of a supercharger. Among the modifications, the engine block and heads were modified to enhance coolant flow, the crankshaft was upgraded to a fully counter weighted forged unit, the billet roller cam had a unique profile, and the pistons were made of a stronger hypereutectic alloy. The supercharger utilized was an Eaton M90 Roots-style, designed for mounting atop the intake manifold. Boost pressure during hard acceleration under ideal conditions is approximately.
In 1990 for the 1991 model year, a V8 was offered in the Thunderbird once again, slotting in between the standard and supercharged versions of the 3.8 L V6. The V8 5.0 L engine produced at the Cleveland Engine Plant #1, now with more power and torque relative to the last time the engine was used in the Thunderbird in 1988. For 1992, there was a one-year only Thunderbird Sport model featuring the 5.0 liter V8 engine, the Super Coupe front fascia with fog lamps and colored coordinated lower bodyside stripes. In 1993, the 1994 model year Thunderbird received a substantial refresh, including stylistic changes inside and out and mechanical enhancements. In particular, the Windsor 5.0 was replaced with Ford's new Modular 4.6 L OHC V8 while the Super Coupe's supercharged V6 was enhanced to produce more power and torque. The performance increase is largely attributed to the tighter gap tolerance of the supercharger rotors allowed by the use of resin coating and a new high flow supercharger case. Simultaneously, the AOD automatic transmission was replaced by the also-new electronically controlled 4R70W 4-speed automatic in all instances where the AOD was previously used in the Thunderbird.
In 1995, Ford did little to commemorate the Thunderbird's 40th anniversary; instead, choosing to reduce its investment in the tenth generation model. While the Thunderbird received minor changes for 1996, the Super Coupe model was discontinued the previous year and the options list for the remaining models was condensed. In the mid-1990s, Ford decided to discontinue the tenth generation Thunderbird with the last example of the car rolling off the assembly line in Lorain, Ohio on September 4, 1997.

Eleventh generation (2002–2005)

After a five year hiatus, Ford introduced the 2002 Thunderbird. Returning to the original formula for the Thunderbird, the latest version had a two-passenger convertible/removable hardtop configuration like the first-generation Thunderbird and styling strongly recalling the original.
The eleventh generation Thunderbird was manufactured at Ford's Wixom Assembly Plant, sharing the Ford DEW platform with the Lincoln LS, Jaguar S-Type and XF. Though the Thunderbird's exterior styling was unique relative to the others, the instrument panel, steering wheel and other trim pieces were borrowed from Lincoln LS. The sole engine of the Thunderbird was a Jaguar-designed AJ-30 3.9 L DOHC V8, a short-stroke variant of the Jaguar AJ-26 4.0 L V8, rated at and of torque — in combination with Ford's 5R55N 5-speed automatic transmission. The AJ-30 V8 was replaced by the AJ-35 in 2003 and later Thunderbirds, bringing with it variable valve timing and electronic throttle control as well as and of torque. Complementing the extra power and torque provided by the AJ-35 V8, a manual shift feature for the 5-speed automatic called SelectShift was available as an option in 2003 and later Thunderbirds. With sales dropping off significantly after its first model year, Ford ended Thunderbird production with the 2005 model year the Thunderbird. The last Thunderbird was manufactured on July 1, 2005.

NASCAR

Thurderbirds first made serious inroads into NASCAR racing in the 1959 season. The combination of the second generation body style and the newly available 430 CID V8 took drivers Curtis Turner, Johnny Beauchamp, "Tiger" Tom Pistone and Cotton Owens to victory lane. In the 1960 season, most teams returned to using the conventional full sized Ford body style, and the T-Bird made only sporadic appearances through the rest of the 1960s, with no additional wins.
Beginning in 1977, Thunderbird bodied racecars replaced the Torino as Ford's primary body style in NASCAR, starting a trend of luxury coupe type bodystyles being used as a sheet metal source on the race track. Bobby Allison won 13 races with this car driving for owner Bud Moore in the 1977 through 1980 seasons even though the cars looked boxy and unaerodynamic. During the period 1981–1997, the downsized and aerodynamically clean Thunderbirds were successful in NASCAR stock car racing before they were replaced by Taurus-based bodies in 1998. The 1983–1988 bodied cars routinely broke the 200 mph barrier, in one case during a qualifying session set the record of the fastest lap in stock car history at 44.998 seconds with an average speed of at Talladega Superspeedway, a record that still stands. Bill Elliott and Davey Allison, in particular, were successful with the cars, with Elliott winning the 1988 championship. Alan Kulwicki also won the championship in 1992 in a car nicknamed "Underbird", due to his underdog status as a driver.
