Mach 1 History
The Ford Mustang has been celebratedover the past half-century with manyspecial performance versions, includingseveral unique models that have proudlycarried their own nomenclature. Therehave been HiPos, Shelbys and GTs, plusCalifornia Specials, Bosses, Cobras, SVOsand 5.0s, Cobra Jets and Bullitts – eachwith distinct design cues and equipmentenhancements targeted at specific buyers.Of them all, perhaps the best-known andmost accessible to the widest owner baseis the Mustang Mach 1, a sporty fastbackfirst introduced in 1969 that had the look,features and performance that helpeddefine the muscle car era.
In postwar America, the Jet Age influencewas all the rage -- especially in the autoindustry, where tail fins and air intakesinfluenced progressive car designs. It wasthen when the terms Mach 1 and SoundBarrier became part of public conversation,as jets and rockets were being employedin aeronautic experiments to helphumankind soar past the speed of sound.
Ford’s first use of the Mach 1 name cameon a concept vehicle – a wheel-lesssingle-seat pod tethered to an arm thatallowed it to glide on a cushion of airaround a circular track set up at the FordRotunda in the spring of 1959. Ford’sLevacar Mach 1 Concept was anair-propulsion flying car of sorts,suggesting that vehicles in the future coulduse ducted air to levitate and maneuver athigh speed while off the ground.
The Mach 1 name was resurrected in 1966for another Ford concept car that wasmeant to preview some aerodynamic andstyling advances for a futuristichigh-performance Mustang fastback. Thetwo-seat Mustang Mach 1 Concept thatwas shown at the 1967 Detroit Auto Showfeatured a slanted areo-grille, severelychopped roof, large air scoops and steeplyslanted rear glass as part of a fullhatchback -- a design feature thatwouldn’t appear in production until 1974.Ford updated the Mustang Mach 1 Conceptwith a new front-end treatment in time fortouring the auto show circuit in 1968 toherald the popular pony car’s third stylingrefresh due the following year.
By the time 1969 had rolled around, theagain restyled and upsized Ford Mustangwas facing a series of new challenges, bothin the muscle car wars taking place out inthe marketplace by an onslaught ofpowerful new competitors, and inside ofFord Motor Company, where a new, Steedfor Every Need marketing approachexpanded pony car offerings to five distinctmodels with at least 10 differentpowertrain combinations. Ford's Mustanghad galloped into its fifth model yearrefreshed with unmistakable good looks,thanks to its 2+2 fastback now called theSportsRoof, featuring upper rear-quarterscut with forward-facing scoops and adramatic tail that incorporated an upsweptrear edge.

Even though the GT equipment groupintroduced in 1965 was again available fora final year, it was overshadowed for 1969,as the hot ticket was an all-new Mach 1model – wearing the name borrowed fromthose radical recent Mustang show cars.The new Mustang Mach 1 came standardwith the 351, a desirable mix of appearanceenhancements, plus special reflectivebodyside stripes and an uplevel interior.Later, a flat-black rear decklid spoiler anda set of rear window louvers were addedas dress-up options. To many enthusiaststoday, a ’69 Mach 1 equipped with anoptional new-for-’69 428 Cobra Jet V-8 isthe first true Mustang muscle car and atop-shelf collectible.
Other than yet another front-endfreshening (including going back to justtwo headlamps and adding non-functionaloutboard air inlets) and the elimination ofthe side scoops, the biggest change to the1970 Mustang lineup was a move to theCleveland-design 351 V-8 over the Windsor351 version from the year before. The GTmodel was dropped in the face of theMach 1's popularity, but the 428CJ engineoption was again available across theboard. By 1971, Ford’s famedfirst-generation pony car had alreadyundergone its fourth major facelift, growingin every dimension to accommodate evenbigger engines. The ’71 Mustang featuredan extended nose with a body that waswider, close to a foot longer and around600 pounds heavier than the original. TheSportsRoof-only Mach 1 model was nowFord's bread-and-butter enthusiast model,especially with the optional new big-block429 Cobra Jet engine, good for 370horsepower.
There were only minor changes on tap forMustang in 1972 and ’73, most of themdealing with the options list and thecontinuing emasculation of engineofferings and horsepower in the face ofemissions and fuel economy regulations,
as well as the elimination of a convertible.The automotive performance world sooncame to a screeching halt in the wake ofan oil embargo and resulting gasshortages, forcing most Americans toabandon their muscle cars andV-8-powered rides in favor of smaller,more fuel-efficient vehicles. Ford saw themarket shift as the perfect time to returnits pony car to its roots – a compact,affordable, sporty car whose styling andimage captured the spirit and imaginationof the American public.
When the new-from-the-ground-up,second-generation Mustang II waslaunched for the 1974 model year, it wasthe first Mustang equipped with afour-cylinder engine. An all-new 2.3-literI-4 produced around 90 horses as thestandard powerplant for the downsizedMustang II - yet performance was roughlyequivalent to the previous Mustang’s biginline six. The Mustang II was available asa hardtop two-door notchback coupe or athree-door hatchback-style fastback.Buyers had a choice of either I-4 or V-6power, as well as a three-speed automaticor four-speed manual transmissions. Tokeep Mustang’s performance image goingeven in a world where consumers favoredfuel economy over horsepower, anenthusiast-focused Mustang II Mach 1model was offered as a three-doorhatchback-style fastback, replete withbucket seats.
There’s little question that the saving gracefor the Mustang II’s performancereputation came when Ford finally realizedit needed to put the 302 V-8 back onto theMustang option list for 1975-78. The V-8was available in any model, but first onlymated to a three-speed automatictransmission, as a four-speed manual wasdelayed a full year until a suitable clutchcould be tooled up. The two-barrel 302shoehorned into the Mustang II gotcatalytic converters to help meet 1976’s
