Mercury Cougar is a nameplate applied to a diverse series of automobiles sold by the Mercury division of Ford from 1967 to 1997 and from 1999 to 2002. While the nameplate is most commonly associated with two-door coupes, at various times during its production, the Cougar was also marketed as a convertible, four-door sedan, station wagon, and hatchback. With 2,972,784 examples produced, the Cougar is the highest-selling vehicle ever produced by the Mercury brand; its 34-year production is second only to the Grand Marquis in the Mercury model line (produced for 36 years). During the 1970s and 1980s, the Cougar was closely tied to the marketing of the Mercury division; Mercury advertised its dealers as "The Sign of the Cat" with big cats atop Lincoln-Mercury dealer signs. In line with the Cougar, several animal-related nameplates were adopted by the division, including the Bobcat, Lynx, and Sable. During its production, the Cougar was assembled at the Dearborn Assembly Plant (part of the Ford River Rouge Complex) in Dearborn, Michigan from 1967 to 1973, San Jose Assembly (Milpitas, California) from 1968 into early 1969, Lorain Assembly (Lorain, Ohio) from 1974 to 1997, and at Flat Rock Assembly (Flat Rock, Michigan) from 1999 to 2002.
Overview
During much of its production life, the Cougar followed tradition within the Mercury division, marketed as a Mercury counterpart of a Ford vehicle. Distinguished by a distinct exterior (ranging in degree from grilles and lighting components to nearly the entire exterior), to streamline its production, the Cougar shared its chassis underpinnings with Ford vehicles throughout its production life. For its first two generations, the Cougar was derived from the Ford Mustang; initially developed as a pony car, it replaced the Cyclone muscle car in the Mercury model line. For its third and fourth generations, the Cougar adopted the chassis of the Ford Torino intermediate. Initially the counterpart of the Ford (Gran Torino) Elite, the fourth generation was split into two model lines, replacing the Montego as the Mercury intermediate (alongside the Ford LTD II), with the Cougar XR7 becoming the counterpart of the Ford Thunderbird. For its fifth and sixth generations, the Cougar adopted the compact Fox platform. For the fifth generation, the Cougar was again two model lines, with the Cougar XR7 derived from the Thunderbird and the standard Cougar replacing the Monarch as the counterpart of the Ford Granada. The sixth generation Cougar, derived from the Thunderbird, reverted to the two-door coupe body style. For its seventh generation, the Cougar introduced the MN12 platform, developed for the Cougar, Thunderbird and Lincoln Mark VIII. After 1997, the Cougar and Thunderbird were discontinued (the Mark VIII was discontinued after 1998). For its eighth generation, the Cougar returned for 1999 as a sports compact hatchback. Sharing a chassis with the Ford Contour, the model line began development as a third generation of the Ford Probe, shifting to Mercury as its development neared completion. Sold only under the Mercury brand, this generation is the only version of the Cougar with no direct Ford counterpart (though export examples were badged as Ford Cougars).
Seventh generation (1989-1997)
On 26 December 1988, the seventh-generation Mercury Cougar was introduced for the 1989 model year. Developed from the second quarter of 1984, as a counterpart of the tenth-generation Ford Thunderbird, the $2 billion redesign of the two vehicles was intended to create handling benchmarked against far more expensive coupes (BMW 6-Series, Mercedes-Benz 560SEC, Jaguar XJS) while remaining in the same price segment. During the development of the 1989 Cougar, the form factor of coupes shifted significantly, as the quartet of GM G-body coupes were replaced by front-wheel drive vehicles; the introduction of the Acura Legend by Honda marked the introduction of Japanese-produced luxury vehicles. At its 1989 debut, the Cougar was marketed largely as the flagship coupe of the Mercury division. As Mercury revised its model line during the 1990s, the Cougar became the sole two-door model offered by the division. As market demand shifted away from large two-door coupes, the Mercury Cougar and Ford Thunderbird were discontinued after the 1997 model year, with the final example produced on 4 September 1997.
Chassis
The seventh-generation Mercury Cougar is built upon the Ford MN12 platform. Designed specifically for the Mercury Cougar and Ford Thunderbird, the MN12 chassis retained the use of rear-wheel drive. While its exterior footprint changed negligibly, in a major change, the wheelbase was expanded nine inches to 113 inches (longer than a Mercedes-Benz 560SEC). Centered around the design of the MN12 chassis was its use of four-wheel independent suspension in place of a live rear axle. With the exception of the Chevrolet Corvette, the Ford MN12 chassis marked its first use in a mass-produced American automobile. In front, the Mercury Cougar was configured with a short/long arm wishbone suspension. As an option, the Cougar was available with 4-wheel antilock disc brakes (standard on the Cougar XR7). As part of the 1989 redesign, the MN12 chassis was powered solely by a 3.8L V6, as the lowered hoodline of the MN12 was too low to properly house the 5.0L V8, the engine was removed from the model line (marking the first time no V8 was available for the Cougar or Thunderbird). LS-trim Cougars were offered with a naturally aspirated 140 hp version of the V6, while the XR7 was powered by a 210 hp supercharged version (serving as the replacement for the turbocharged 2.3L inline-4). The naturally aspirated V6 was paired with a 4-speed automatic transmission, while the supercharged V6 was offered with a 5-speed manual (with the automatic as an option).
For 1991, to increase demand for the Cougar, Mercury introduced a 200 hp version of the 5.0L V8, a redesigned intake manifold allowed for sufficient underhood clearance. Offered as an option on the Cougar LS, the V8 replaced the supercharged V6 in the XR7 (which also marked the end of the 5-speed manual in the MN12 Cougar). Originally slated for 1993, the 1994 Cougar shifted from the overhead-valve 5.0L V8 to a 205 hp 4.6L SOHC V8 (shared with the Mercury Grand Marquis). In another 1994 change, the 4R70W electronically controlled version of the AOD 4-speed automatic was introduced for both the V6 and V8 engines.
