Mercury Marquis

For 1967, Mercury introduced two hardtop model lines above the Park Lane to serve as the counterpart of the Ford LTD. The Park Lane Brougham was a four-door, with the Marquis offered solely as a two-door. While all full-size Mercury two-doors were hardtops, the Marquis was fitted with a standard vinyl roof giving it a wider C-pillar. While sharing a roofline with the Ford LTD, the Marquis differed from its Ford counterpart from the use of higher-specification interior trim (wood trim in place of simulated wood, optional leather unavailable on the LTD). As with other Mercury sedans, the Marquis was built on a 123-inch wheelbase (4 inches longer than the LTD). In contrast to the full-width bench seat of other Mercury lines, the Marquis was fitted with "Twin Comfort Lounge" front seats. Designed as a 50/50 split bench seat, the design combined the 3-passenger capacity of a bench seat with the individual legroom adjustment of bucket seats. A 4-speed manual transmission was standard, with a 3-speed automatic as an option. A 3-speed manual replaced the previous 4-speed, with the automatic returning as an option. As an option for both years, the 428 cubic-inch Super Marauder V8 was offered, producing 345 hp; for 1968, the engine was retuned to 340 hp. == Second generation (1969–1978) ==

}} For 1969, Mercury underwent a revision of its full-size range. Serving as the successor to the four-door Brougham and two-door Park Lane, the second-generation Marquis was expanded to a full range of body styles, slotted above the Monterey. For 1975, the full-size Mercury range was reduced solely to the Marquis (including the Brougham and Grand Marquis trims). The wheelbase was longer on the two-door and four-door sedan than the Mercury Colony Park station wagon, the Lincoln Continental Mark III and the Lincoln Continental Mark IV while sharing the chassis with the 1970 Lincoln Continental sedan. Front disc brake and rear drum brakes were standard; power brakes became standard in 1971. For 1973, "Sure-Track", an early form of anti-lock braking, was introduced as an option; four-wheel disc brakes became an option for 1975. Powertrain For the second generation of the Marquis, Mercury revised the powertrain line. Along with ending its Marauder branding for engines, Mercury replaced both the 390 and 428 FE-series engines with a 429-cubic inch 385-series V8. A short-stroke version of the Lincoln 460 V8, the Marquis offered the 429 with 2-barrel and 4-barrel carburetors (320 and 360 hp, respectively). The manual transmission was discontinued, paired solely with the 3-speed Ford C6 heavy-duty automatic. During the 1972 model year, the Marquis received the 460 from Lincoln as an option; for 1974, the 460 replaced the 429 outright. As the 1970s progressed, Mercury began efforts to improve emissions and fuel economy of its full-size range; following the discontinuation of the Monterey and the introduction of the Grand Marquis, smaller-displacement Ford 335 engines replaced the 460 as the standard engine offering. For 1975, the 402 cubic-inch Ford 400 V8 was introduced (largely as a successor to the 429), with the 351 cubic-inch Ford 351M V8 becoming the standard engine for the Marquis in 1978. In California and for "high-altitude" use, the 400 remained standard equipment; regardless of usage, the 460 (standard on the Marquis Brougham and Grand Marquis through 1977) remained available as an option until the end of the generation. The C6 transmission remained paired to the 460, with the 400 and 351M using the lighter-duty FMX transmission. Body design The second-generation Marquis was expanded from the previous two-door hardtop to a full range of body styles, inheriting the four-door hardtop from the Brougham and four-door sedan and two-door convertible from the Park Lane series. Under the 1969 rebranding of Ford and Mercury station wagons, the Colony Park station wagon became part of the Marquis line. Alongside the woodgrained Colony Park, a Marquis station wagon (without wood paneling) was introduced. For 1971, the Marquis underwent a revision of the exterior and interior; the convertible body style was dropped (along with the Marauder fastback). Distinguished by the elimination of vent windows and framed door glass (for sedans and station wagons), Mercury saw the introduction of the "pillared hardtop", a sedan combining a thin B-pillar and frameless door glass (to mimic the appearance of a pillarless design). The revision also included the use of fender skirts and wraparound taillamps. The dashboard underwent a redesign, clustering the instruments and controls closer to the steering wheel. For 1972, the grille shifted to an egg-crate design (with a similar panel between the taillamps). In line with federal mandates, the Marquis adopted seatbelt warning buzzers.

Largely coinciding with the addition of 5-mph bumpers for the front and rear fascias, the roofline of the Marquis saw a complete redesign.). For 1974, the grille underwent a redesign (nearly matching that of the Lincoln Continental), shifting to a vertically-oriented layout and eliminating the egg-crate trim of the headlamp covers. Following their addition to the front fascia, the Marquis received 5-mph rear bumpers. In response to pending safety regulations, the four-door hardtop was offered for the last time. For 1975, the front fascia saw several revisions, with a larger radiator-style grille (with the "Mercury" block lettering replaced by a script above the left headlamp); in contrast to the Ford LTD Landau and the Lincoln Continental, the headlamp doors were revised with chrome border trim and a crest emblem. The rear fascia received padded vinyl trim (body color or contrasting) between the taillamps. While Ford and Lincoln added B-pillars (and opera windows) to their two-door sedans, Mercury retained its hardtop roofline. For 1976 though 1978, the Marquis saw few visible changes; in 1976, a Landau vinyl roof option was introduced for Brougham and Grand Marquis two-doors, while all versions of the Marquis were marketed as "Ride-Engineered" (promoting its successful ride comparisons against more expensive European sedans of the time). For 1978, the Marquis was given a redesigned grille, retaining a similar radiator-style design. Alongside the 1978 Chrysler New Yorker two-door, the 1978 Mercury Marquis was the final pillarless two-door hardtop (with retractable rear side windows) offered by an American automobile manufacturer.

Following the discontinuation of the Monterey after 1974, all full-size Mercury sedans took on the Marquis nameplate. the Grand Marquis became a stand-alone trim line above the Brougham for 1975. From 1969 to 1978, the Colony Park was included as part of the Marquis model range, with Mercury also offering a non-woodgrain Marquis station wagon. == Third generation (1979–1982) ==

For the 1979 model year, Mercury introduced the third-generation Marquis, marking the first ground-up redesign of the full-size range since 1969. Trading places with the Cougar as the longest Mercury vehicle, the Marquis shed 17 inches in length and over 1,000 pounds in curb weight (in comparison to its 1978 predecessor). For the first time since 1955, the full-size Mercury station wagon was produced with a curb weight under 4,000 pounds. While downsizing of the Marquis resulted in an exterior footprint closer in size to the intermediate Cougar (prior to its downsizing for 1980), the model line saw an increase in overall interior space (through a taller roofline and redesigned seats); a significant increase in glass area contributed to improved outward visibility. For 1983, Mercury rebranded its entire full-size line under the Grand Marquis nameplate; under minor revisions, the design was produced through the 1991 model year. Chassis specifications The third-generation Marquis is based upon the rear-wheel drive Ford Panther platform. An all-new design developed for the downsizing of full-size product ranges for all three Ford Motor Company divisions, the architecture is an evolution of the previous-generation chassis (introduced in 1969). For the first time in the history of the division, the full-size Mercury shared a common wheelbase with Ford, with both the Marquis and Ford LTD using a wheelbase; reduced from the previous (or from for station wagons). For 1980, the Panther chassis was also adopted by Lincoln, introducing a downsized Lincoln Continental (Town Car from 1981) and the Continental Mark VI. The Panther architecture underwent several design revisions over previous-generation designs. While the double-wishbone independent front suspension was largely unchanged, the live rear axle was changed from a 3-link to a 4-link layout (all four wheels were supported by coil springs). Due to cost considerations, the optional anti-lock brake system and four-wheel disc brakes were dropped in favor of upgraded front disc brakes; power brakes were standard. the now-optional 5.0 L V8 was offered on Brougham-trim Marquis and Grand Marquis four-door sedans. For 1982, the 5.8 L V8 was dropped from the US-market Marquis, with sales continuing in Canada.). Similar to the Mark V and Mark VI, the Marquis was styled with non-functional) fender louvers behind the front wheels (and vents in the front bumper). For 1981, the vents were removed from the front bumper (for 1982, they were deleted from the fenders). Alongside trim and badging details, the full-size Ford and Mercury sedan interiors were styled with their own dashboard designs; the previous two-spoke steering wheel was replaced by a four-spoke design. While the LTD received a horizontal full-width speedometer, the Marquis received two square pods for the instrument panel (with white-face instrument bezels). For 1982, a digital trip computer was introduced as an option (replacing the analog clock in the dashboard). Trim The third-generation Marquis carried over its trim nomenclature from the previous generation. Alongside the standard Marquis, Mercury also sold the Marquis Brougham and the top-trim Grand Marquis. The woodgrain-trim Colony Park was trimmed as either a Marquis or a Grand Marquis (dependent on options Along with its Ford LTD counterpart, police-use versions of the Marquis were fitted with a model-specific speedometer Production figures == Fourth generation (1983–1986) ==

For 1983, the fourth-generation Marquis was introduced as Mercury shifted the nameplate to the midsize segment to replace the slow-selling Cougar sedan and station wagon. Within Mercury, the Cougar XR-7 was replaced by a redesigned two-door Cougar, with all full-size Mercury sedans adopting the Grand Marquis nameplate. Effectively downsizing the model range for a second time, the 1983 Marquis shed nearly 9 inches in wheelbase, nearly 16 inches in length, and up to 900 pounds of curb weight (dependent on powertrain and bodystyle). As with previous generations, the fourth-generation Marquis was the Mercury counterpart of the Ford LTD (in 1983, rebranded to replace the Granada). Coinciding with the design change, production of the model line shifted from St. Louis Assembly to Chicago Assembly (Atlanta Assembly adopted production of the fourth-generation Marquis). Ford Venezuela marketed the Mercury Marquis (under slight trim revisions) as the Ford Cougar from 1983 to 1985. As Ford transitioned its car platforms to front-wheel drive, the Marquis was replaced by the Mercury Sable, with Mercury selling both lines for 1986. Chassis specifications The fourth-generation Marquis uses the rear-wheel drive Ford Fox platform. Initially developed for compact sedans, the architecture was expanded for a wide range of Ford and Lincoln-Mercury vehicles; as a multiple-wheelbase design, the Fox platform was introduced for the mid-size segment for 1980. A 105.6 inch wheelbase As with the previous generation, the Marquis used front disc brakes with rear drum brakes. Station wagons were marketed with six-cylinder engines; a 3.3 L inline-6 (dating back to the Falcon/Comet) was the standard engine for station wagons and optional on sedans. A 3.8 L V6 was optional on both body styles, replacing the inline-6 entirely for 1984. Sold only in Canada from 1984 to 1985, the Marquis LTS was powered by the 5.0 L HO V8 (shared with the Mustang). A 4-speed manual was standard with the 2.3 L engine, and was deleted after 1983; subsequent production used the previously optional 3-speed C3 automatic. The 3.3 L six was paired solely with a 3-speed C5 automatic. The 3.8 L V6 used two different transmissions: the 4-speed AOD automatic was standard for 1983, becoming an option for 1984; the 3-speed C5 became standard for 1984 (replacing the AOD entirely for 1985). All examples with the 5.0 L V8 (the LTS) used the 4-speed AOD automatic. Body design The fourth-generation Marquis was produced as a four-door sedan and as a five-door station wagon (the two-door was discontinued, with the Cougar becoming the sole Mercury mid-size coupe. Sharing its entire bodyshell with its Ford LTD, the Marquis was distinguished by its own grille, taillamps, and parking lamp lenses. For the 1985 model year, the Marquis underwent a minor exterior revision; along with revised taillamps, Mercury lettering in the grille was replaced with a centered crest emblem. The interior of the Marquis and LTD was largely shared between the two model lines (with the exception of the interior door panels). To save development costs, the Marquis retained the dashboard design of the Cougar XR-7 coupe (mixing wood and silver trim), adopting its electronic instrument panel option. Adopted from the full-size Marquis and the Cougar XR-7, the Marquis continued the use of an electronic trip computer. Production figures == Discontinuation ==

For the 1986 model year, Mercury introduced the front-wheel drive Mercury Sable, replacing the Marquis as its mid-size model line; both models were sold concurrently through the 1986 model year. The final example was produced by Atlanta Assembly on December 13, 1985 and by Chicago Assembly on January 3, 1986. Originally introduced as the third-generation Marquis in 1979, the design of the Grand Marquis was produced nearly unchanged through the 1991 model year. After an extensive redesign (though retaining the Panther chassis) for 1992, the Grand Marquis remained in production for 19 model years, becoming the final vehicle produced for the brand in January 2011. == References ==
