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

tighter emissions standards, and saw anincrease to 139 horsepower – nearly equalto the ’73’s standard V-8 power level. TheMach 1’s optional Competition Suspensionpackage offered stiffer springs, adjustableshock absorbers and fatter front and rearstabilizer bars to improve handling, andkept it a popular enthusiast choice over allfive years of Mustang II's production. Bythe dawn of the third-generation Mustang,the Mach name would not return again tothe Mustang line until some 25 years later.
After the 1979-93 Fox Body Mustang yearshad come and gone with the reintroductionof a GT model, new sheet metal on arevamped SN-95 platform helped torekindle consumer interest in afourth-generation Ford Mustang.Enthusiasts lavished their attention uponthe 1993-1999 Mustang Cobraperformance model developed by the FordSpecial Vehicle Team skunkworks group,while Ford engineers looked to specialtymodels to fill the mid-market slot betweenthe standard Mustang GT and theupmarket Cobra.
After the success of the 2001 Bullitt, anew-for-2003 Mach 1 was launched tooffer fans some design cues from its '69namesake, including a blackout hood,black front air-dam extension and reardecklid spoiler – even bodyside scoops. Tomatch its aggressive look and hardwareupgrades, the '03 Mach 1 was powered bya 305-horsepower, 4.6L DOHC modularV-8. Unlike the SVT Cobra, the Mach 1offered an automatic transmission optionin lieu of the manual, and consequentlydrew a new group of enthusiast buyers intothe Ford fold. The strong customerresponse prompted another year of Mach1 production for 2004, the Mustang's finalyear on the fourth-gen platform.
Thanks to a popular mix of appearance,features and power, the 1969-73 Mach 1'sproved to be everyman's muscle car, andhave earned a respected place in Mustangperformance lore. Beyond those classicyears, the Mach 1 carried over for all fiveyears of the often overlooked 1974-78'sbefore a hiatus that ended with themodern and muscular 2003-04's. Mach1’s return to the Mustang lineup for 2021will add a new chapter on modern-daymuscle for this beloved model, and willcement its rightful place near the very topof Mustang performance history.

EMISSION LAW
WARNING: Do not remove or alterthe original equipment floor covering orinsulation between it and the metal floorof the vehicle. The floor covering andinsulation protect occupants of thevehicle from the engine and exhaustsystem heat and noise. On vehicles withno original equipment floor coveringinsulation, do not carry passengers in amanner that permits prolonged skincontact with the metal floor. Failure tofollow these instructions may result infire or personal injury.
U.S. federal laws and certain state lawsprohibit removing or rendering inoperativeemission control system components.Similar federal or provincial laws mayapply in Canada. We do not approve of anyvehicle modification without firstdetermining applicable laws.
Tampering with emissionscontrol systems includingrelated sensors can result inreduced engine power and the illuminationof the service engine soon light.
Tampering With a Noise ControlSystem
Federal laws prohibit the following acts:
•Removal or rendering inoperative byany person other than for purposes ofmaintenance.
•Repair or replacement of any device orelement of the design incorporated intoa new vehicle for the purpose of noisecontrol prior to its sale or delivery tothe ultimate purchaser or while it is inuse.
•The use of the vehicle after any personremoves or renders inoperative anydevice or element of the design.
The U.S. Environmental Protection Agencymay presume to constitute tampering asfollows:
•Removal of hood blanket, fender apronabsorbers, fender apron barriers,underbody noise shields or acousticallyabsorptive material.
•Tampering or rendering inoperative theengine speed governor, to allow enginespeed to exceed manufacturerspecifications.
If the engine does not start, runs rough,experiences a decrease in engineperformance, experiences excess fuelconsumption or produces excessiveexhaust smoke, check for the following:
•A plugged or disconnected air inletsystem hose.
•A plugged engine air filter element.
•A clogged fuel filter.
•Contaminated fuel.
•Air in the fuel system, due to looseconnections.
•Fuel system leaks, due to looseconnections.
•An open or pinched sensor hose.
•Incorrect engine oil level.
•Incorrect fuel for climatic conditions.
•Incorrect engine oil viscosity forclimactic conditions.
Note:Some vehicles have a lifetime fuelfilter that is integrated with the fuel tank.Regular maintenance or replacement is notneeded.
Note:If these checks do not help youcorrect the concern, see your authorizeddealer as soon as possible.
