2023 Mustang (CZG) Canada/United States of America, Vehicles Built From: 14-11-2022, enUSA, Edition date: 202209, First-PrintingTable of Contents
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
