Generation 01 · 1965–1973

THE ORIGINAL

A long hood, a short rear deck, and a remarkably personal idea of performance. The original Mustang offered a choice of body styles, engines, and equipment that let the same basic car become a daily driver, a boulevard cruiser, or a competition machine.

THE CHAPTER IN CONTEXT.

The first cars reached buyers in April 1964 as 1965 models. Early-production cars are often called 1964½. The 1967 redesign created room for larger engines; 1969 introduced the Boss models and Mach 1. The larger 1971–73 cars closed the first chapter.

BUYING & OWNERSHIP.

Inspect the cowl, floor pans, torque boxes, shock towers, rear frame rails, and trunk drop-offs. Verify engine and body identification against year-specific records. Restoration quality and structural integrity matter more than fresh paint.

Use the exact year and configuration when sourcing parts or maintenance instructions. Options, engine swaps, and regional differences can change applicability.

YEAR BY YEAR.

1965

The original formula

The first full model year brings hardtop, convertible, and 2+2 fastback choices. Early 1964 production is commonly called 1964½; the cars are 1965 models.

1966

Refining the original

The familiar first-generation shape continues, with revised grille and trim details. The broad option list lets buyers tailor appearance and performance.

1967

Room to grow

A larger body and engine bay broaden the Mustang formula. A big-block 390 becomes available, and the Shelby GT500 joins the story.

1968

More performance choices

The fastback becomes a screen icon in Bullitt. The 428 Cobra Jet and California Special add distinct chapters to the model year.

1969

Meet the legends

Mach 1, Boss 302, and Boss 429 make 1969 one of the most recognizable Mustang years. The SportsRoof body replaces the earlier fastback shape.

1970

A sharper expression

A revised front end gives the Mustang a new face. Boss and Mach 1 models continue, and the 351 Cleveland becomes part of the powertrain story.

1971

The big-body era begins

The Mustang grows again, with a longer, wider presence. Boss 351 and Mach 1 anchor the performance side of the range.

1972

Changing measurements

The larger first-generation body continues. Published horsepower figures must be read in the context of the transition to SAE net ratings.

1973

Closing the first chapter

The original platform reaches its final model year. Convertible production ends before returning a decade later.
