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.
