Ford Mustang

Ford Mustang at a glance

The Mustang has its own page in our Ford catalogue, and the early years are told in detail in the history of the Ford Mustang. For the place of the car among its rivals, see the American muscle car guide.

How the pony car began

The project, known inside Ford as T-5, was pushed by Lee Iacocca, then general manager of the Ford Division, with Donald N. Frey as chief engineer. Gale Halderman drew the side view that became the first clay model. Ford credits John Najjar with the name; he had also co-designed the 1961 Mustang I prototype with Philip T. Clark. In Germany the car was sold as the T-5 until December 1978, because the Mustang name there belonged to Krupp.

Production started in Dearborn on 9 March 1964, and the first public sale took place in St. John's, Newfoundland, on 14 April. Three days later the Mustang was shown at the New York World's Fair — sixteen days after the Plymouth Barracuda. The early cars are known as "1964½" models, although Ford sold and titled them as 1965 models; 121,538 of them found buyers in that short period.

Ford had expected fewer than 100,000 sales in the first year. More than 400,000 were sold, and over a million cars were built in the first 18 months. The 1965 model year alone accounts for 559,451 cars and 1966 for 607,568. The Mustang was also the first automobile to receive the Tiffany Gold Medal for American design.

The first generation (1964–1973)

The first Mustang used the running gear of the Falcon compact under a long-bonnet, short-deck body. Buyers could choose a hardtop, a convertible or, from August 1964, a 2+2 fastback, which Ford called SportsRoof from 1969. The engine range ran from straight-six engines to V8s. The long options list was part of the idea: the same body could be an economical commuter or a fast car.

Performance came quickly. The 289 cu in Hi-Po V8 (K-code) was rated at 202 kW (271 hp) from 1964 to 1967. Car and Driver tested a 1965 HiPo with a 4.11 axle: 60 mph came up in 5.2 seconds, and the quarter mile took 14.0 seconds. The 390 FE V8 followed, and from 1968 the 428 Cobra Jet with 250 kW (335 hp) turned the Mustang into a proper muscle car.

The body grew with the engines. The 1967 car was larger inside and out. The 1969 update added 97 mm of length on an unchanged 108-inch wheelbase, and for 1971 the car became 3 inches wider so that the big 429 V8 would fit. The first generation ended in June 1973.

Boss, Mach 1 and Shelby: the V8 Mustangs

The Mach 1 package arrived for the 1969 model year and became the best-known sporty Mustang of the period. The same year Ford built two Boss models to homologate engines for racing: the small-block Boss 302, rated at 216 kW (290 hp), and the big-block Boss 429, rated at 280 kW (375 hp). Wikipedia gives 1,628 Boss 302s and 859 Boss 429s sold through 1969.

For 1971 the top engines were the 429 Cobra Jet with 276 kW (370 hp) and the 429 Super Cobra Jet with 280 kW (375 hp). A Boss 351 rated at 246 kW (330 hp) replaced both Boss models. These were the last gross ratings. From 1972 American makers quoted SAE net power, and the 1972 Mustang's strongest engine, the 351 HO, was listed at 205 kW (275 hp) net.

Carroll Shelby's versions began in 1965 as a fastback, the GT350. The racing GT350R won five of six SCCA divisions in its first season. Later came the GT500 with a big-block V8; for 1969 the GT-350 used the 351 Windsor rated at 216 kW (290 hp) and the GT-500 the 428 Cobra Jet. Shelby production ended in 1969, and 789 leftover cars were retitled as 1970 models. The 1967 Shelby GT500 has its own article on 1CARS.

Mustang II, Fox and SN95

The 1974 Mustang II was a different car: smaller, and built on a longer-wheelbase version of the Ford Pinto. It sold 385,993 cars in its first year — close to the original car's twelve-month record of 418,812 — and it was Motor Trend's Car of the Year for 1974. The "5.0" badge first appeared on the 1978 King Cobra.

The third generation of 1979 moved to the Fox platform, which the Mustang shared with 14 other Ford vehicles. The GT returned in 1982 with a high-output 302 cu in (4.9-litre) V8 marketed as the 5.0, and the turbocharged, intercooled 2.3-litre SVO of 1984–1986 showed another way to performance. The Fox Mustang lasted until 1993 and ended with the Cobra R.

The SN95 car of 1994 kept a modified Fox chassis, known as Fox-4, and was again Motor Trend's Car of the Year. Its best-known performance version was the SVT Cobra; the supercharged 2003–2004 model was rated at 291 kW (390 hp). A Bullitt edition appeared in 2001.

The modern Mustang

The fifth generation (S197) of 2005 moved to Ford's D2C platform, used only by the Mustang, and production moved to Flat Rock. Its styling brought back the lines and colours of the original car. The GT had a 4.6-litre V8 with 224 kW (300 hp), and from 2011 the new 5.0-litre "Coyote" V8 gave 307 kW (412 hp). The 2012 Boss 302 was rated at 331 kW (444 hp), and the 2013 Shelby GT500 with a supercharged 5.8-litre V8 reached 494 kW (662 hp).

The sixth generation (S550), unveiled on 5 December 2013, was the first Mustang designed for right-hand drive and sold globally. Its GT reached 343 kW (460 hp) in 2018, and the Mach 1 returned for 2021 with 358 kW (480 hp). The 2020 Shelby GT500 with the supercharged 5.2-litre "Predator" V8 reached 567 kW (760 hp). The GT350 was dropped after 2020.

The seventh generation (S650) went into production on 1 May 2023. The GT has 358–362 kW (480–486 hp), and the Dark Horse 373 kW (500 hp). The road-going Mustang GTD of the 2025 model year uses a supercharged 5.2-litre Predator V8 with 608 kW (815 hp) and 900 Nm, the highest output of any Mustang so far. Sales in calendar year 2025 were 45,333 cars. The electric Mustang Mach-E of 2019 is a crossover that shares only the name.

Racing and recognition

Racing was part of the Mustang story from the start: the Shelby GT350R won five of six SCCA divisions in 1965, and the Boss models of 1969 existed to homologate engines for competition. On the road, the car won Car and Driver's Ten Best award in 1983, 1987, 1988, 2005, 2006, 2011 and 2016.

Its rivals defined the segment. The Chevrolet Camaro arrived in 1966 as a direct answer, followed by the Pontiac Firebird, the Plymouth Barracuda and the Dodge Challenger. Unlike the Camaro, Firebird, Barracuda and Challenger, the Mustang has stayed in production since 1964.

Which Mustang to look at

For a classic with muscle car credentials, the 1967–1970 fastbacks with the 428 Cobra Jet, the Mach 1 and the two Boss models are the reference points; the Boss 429 is the rarest of them. The Fox-body 5.0 GT of the 1980s is the simplest way into a V8 Mustang with rear-wheel drive and a light body. Among modern cars the 5.0-litre GT is the core model, while the Shelby GT500 and the Dark Horse are the track-oriented versions. Figures for every generation can be compared in our car rankings.
