TheMercury Eight is an automobile that was produced by the American manufacturerFord Motor Company under their now defunct divisionMercury between 1939 and 1951. The debut model line of the Mercury division, Ford positioned the full-size Mercury Eight between theFord Deluxe (laterCustom) model lines and theLincoln. In total, Ford assembled three generations of the Eight (before and after World War II).
During its production, the Eight offered a full range of body styles, including coupes, sedans, convertibles, and station wagons. For its first generation, the Eight was produced with its own body, adapting its own version of a Ford body for its second generation; for the third generation, the Eight shared its body with theLincoln.
For the 1952 model year, Ford expanded its namesake division to three nameplates and Lincoln and Mercury to two each, with Mercury replacing the Eight withMonterey (introduced in 1950 as a trim option), lasting until 1974.

The advertisements for this car declared it to be "The car that truly dares to ask 'Why?'", referring to the idea that a big car could not also be economical.[3] The Mercury two-door sedan was listed at US$946 ($21,385 in 2024 dollars[5]), several hundred dollars more than the 1937Ford V-8, several hundred less than theLincoln-Zephyr and about the same as the upper-rangeOldsmobile andDodges,Hudsons, and the lower-rangeBuicks andDeSotos, sales from all of which, it was hoped that customers would trade in their cars for the new Mercury.[3] Its engine was a 95 hp version of theFord flathead V8 engine, its styling was inspired by theZephyr, and it had standard equipmenthydraulic brakes using 12-inchdrums.[3] With a wheelbase of 116.0 in (2,946 mm) and an overall length of 196.0 in (4,978 mm), it was a good-sized car, which the Ford company advertised extensively, together with its up-to-20 mpg performance—"few cars of any size can equal such economy".[3] Double sun visors became standard in 1940.[6][7]
Although "Eight" script would not appear on the front of the hood until the 1941 model year, sales literature prominently referred to the car as the "Mercury Eight" from the very beginning. This is no doubt because the actual series names, 99A in 1939[3] and 09A in 1940,[3] were somewhat less enticing. A 1940 09A model has the words "Mercury Eight" in an emblem that runs from front to rear alongside the top hood lines on both sides. It appears as chrome wording on top of a double red bar.
By the end of 1940 Mercury could run with the headline "It's made 150,000 owners change cars!"[3]

The 1941 Mercury Eight got all-new styling and some engineering improvements. The Mercury now shared its bodyshell with theFord Super DeLuxe and the wheelbase was expanded by 2.0 in (51 mm) to 118.0 in (2,997 mm).[3] There were many chassis refinements, including improved spring lengths, rates, and deflections, plus changes in shackling, shocks, and an improved stabilizer bar, but the old fashioned transverse springs were still used. The new body featured door bottoms that flared out over the running boards, allowing for wider seats and interiors. The car had 2.0 in (51 mm) more headroom, two-piece front fenders (three-piece at first), and more glass area. The front pillars were made slimmer and the windshield was widened, deepened, and angled more steeply. Parking lights were separate and set atop the fenders for greater visibility. Headlight bezels were redesigned. In all closed Mercurys the rear-quarter windows opened out. Front vent wings were now crank-operated, and in closed cars the ventilation wing support bars rolled down with the windows. The 4-doorconvertible, offered in 1940, was gone, but astation wagon was added. Thewoodie wagon's body behind the engine cowl was identical to Ford's, and produced at the company'sIron Mountain plant inMichigan'sUpper Peninsula. The "Eight" script was moved to the rear of the hood. 90,556 Mercury Eights were sold in the 1941 model year.
In 1942 the Mercury Eight's slender bullet parking lights were replaced with rectangular units placed high on the fenders inboard of the headlights. Running boards were now completely concealed under flared door bottoms. The instrument panel now features two identical circles for speedometer and clock with gauges to the left of the speedometer, a glove compartment to the right of the clock, and a large radio speaker cover in the center. The grille looked more like that of theLincoln-Zephyr andContinental. The "Eight" script was gone but an "8" appeared at the top of the grille center. Horsepower was increased to 100. Mercury's biggest engineering news for 1942 was "Liquamatic", Ford's firstsemiautomatic transmission. It was unsuccessful and Mercury would not have anotherautomatic transmission untilMerc-O-Matic appeared in 1951, which was a true automatic. Mercury production for the short 1942 model year totaled only 1,902. Output was halted in February 1942 as American auto plants were converted to the exclusive production of war material.
Although Mercury's prewar history was short, the Mercury Eight had already earned for itself the image of being a fine performer in mph as well as mpg, this "hot car" image quite in keeping with its name, chosen byEdsel Ford, that of the fleet-footed messenger of the gods ofRoman mythology.[3] The Mercury Eight was strongly identified as an upmarket Ford during this period. In 1945 the Lincoln-Mercury division would be established to change that.[3]
A new grille was the most noticeable difference between the 1942 and 1946 Mercurys.[8] It had thin vertical bars surrounded by a trim piece painted the same color as the car.[8] An "Eight" script now appeared down its center. The Liquimatic automatic transmission option was eliminated.[8] The most distinctive new Mercury was the Sportsman convertible.[8] It featured wood body panels.[8] Only 205 examples of it were produced and it was discontinued the following model year.[8] Mercury Eight sales totaled 86,603.[8]
Styling changes were slight in 1947.[8] The Mercury name was placed on the side of the hood.[8] Different hubcaps were used.[8] The border around the grille was chrome plated.[8] The "Eight" script still ran down its center. There was also new trunk trim.[8] More chrome was used on the interior and the dash dial faces were redesigned.[8] The convertible and station wagon came with leather upholstery.[8] The other body styles used fabric.[8] The wood paneled Sportsman convertible was gone.[8] 86,363 Mercury Eights were sold.[8]
For all practical purposes the 1948 Mercury Eights were identical to the 1947s.[8] The major changes consisted of different dial faces and no steering column lock.[8] 50,268 Mercury Eights were sold.[8]
A uniquecoupe utility variant of the Mercury was produced inAustralia from 1946 to 1948.[9] Marketed as the Mercury Club Coupe Utility,[10] it was built on a 118-inch wheelbase and had a carrying capacity rated at 10–12cwt.[9] The 1946 version was coded as the Model S9A and the 1947 and 1948 variants as the Model 6M.[9]
Apanel van model was also offered.[10]

For 1949, Mercury introduced its third-generation design as its first postwar line. The first models released under the combined Lincoln-Mercury Division, the Mercury Eight now shared its body with theLincoln (which no longer carried a divisional nameplate).
Keeping its 118-inch wheelbase, the third-generation Mercury was sized between its two divisional counterparts. The "pontoon" body design eliminated freestanding fenders and running boards (along with widening and lowering the hood). Substantial modernization was made to the chassis, as Ford retired its long-running transverse-leaf suspension and torque-tube drive axle (the former feature, used since 1908 on the Model T).[12] While the rear axle was remained leaf-sprung (with more conventional longitudinal springs), the front suspension was independent with stabilizer bars.[12][13]
TheFlathead V8 (resized to 255 cubic inches) made its return, producing 110 hp.[14] A new overdrive system was optional, activated by a handle under the dash.[1][15]
In a model change, the four-door station wagon was replaced by a two-door version; as with theFord Country Squire, wood construction was relegated to side paneling (still manufactured at theFord Iron Mountain Plant).[8] An 8 tubeAM radio was introduced as an option; full instrumentation was added to the dashboard.[16]
For 1950, theMercury Monterey made its debut as the flagship version of the Mercury Eight. Developed in response to the two-door hardtop coupes introduced by General Motors, the Monterey was a counterpart of theFord Crestliner, Lincoln Lido, and Lincoln Cosmopolitan Capri, featuring a fabric-covered roof and upgraded interior.[12]
For 1951, the Mercury saw minor styling revisions, but introduced the Merc-O-Matic 3-speed automatic as an option (identical to theFord-O-Matic introduced alongside it).[12]
The shift from the Ford to the Lincoln body proved successful for Mercury, increasing sales by over 250,000 vehicles from 1948 to 1949, with the brand becoming the sixth-best selling automobile in the United States.[12] For 1952, Mercury redesigned and expanded its model line, renaming the Eight as the Mercury Custom and establishing the Monterey as its flagship nameplate.[1]

Within its era and beyond, the third-generation Mercury Eight was popular with customizers. In 1949,Sam Barris built the firstlead sled from a 1949 Mercury Eight; the Eight became the definitive "lead sled", much as theFord V-8 (as the"deuce") was becoming the definitivehot rod. The Eights were among the first models to receive an aftermarketOHV engine swap, sinceOldsmobile andCadillac developed the first high-compression OHV V8 engines in 1949, whereas Ford was still using a sidevalve engine.
Sam and George Barris also used the 1949 body style to build "the most famous custom car ever",[17] theHirohata Merc, for customer Bob Hirohata in 1953. Setting a style and an attitude, it had a "momentous effect" on custom car builders,[18] appeared in several magazines at the time,[19] and reappeared numerous times since, earning an honorable mention onRod & Custom's "Twenty Best of All Time" list in 1991.[19]
The Eight remains a very popular subject for car modellers. In 1990,Hot Wheels created thePurple Passion, a model based on the 1949 Mercury with a chopped top.[citation needed]Fiberglass replicas of the Eight, inspired by Sam Barris's car, are still in production and are popular withcustom and rod enthusiasts.[20]
