The radical and boring Ford Mustang concepts that never made production


Ever wonder what Ford Mustang concepts never made production? The process of designing and developing new cars is time consuming and costly. You don’t want to commit to investing hundreds of millions of dollars without seriously considering the what if’s. Over the past five decades, Ford designers and engineers have drawn, built and tested countless concept vehicles with only a small percentage of those concepts ever making it to production.

Below we have complied a long list of Mustang concepts from the Ford archives which never made production.  Some are radical and some are boring but for the most part you can see the pony within.

Ford Mustangs That Never Were: 1961 Avventura, Avanti, Allegro d

1961 Ford Avventura Concept
From late 1961 into mid-1962, Ford designers tried out a wide range of themes for a sporty coupe based on the platform of the new Falcon compact. Each design was given an internal name for the purpose of discussion. One fastback design actually went through at least three different names starting with Avventura before moving on to Avanti and finally Allegro. The fastback design was originally sketched with a hatchback and rear-facing second row seat. While this car never made it to production, a variation of the fastback profile was eventually adopted as the third body style for Mustang.

Ford Avanti Concept
As Avventura moved from sketch to physical design model, the hatch was replaced with a trunk and the rear seat was switched to a more conventional forward-facing orientation. Originally shown internally as Avanti, the name was eventually changed to Allegro, likely because Studebaker had introduced its own production Avanti coupe around the same time.

Ford Mustangs That Never Were: 1961-62 two-seater studies

1961-1962 Two-Seater Studies
Early in the gestation of the original Mustang, Ford designers also considered a number of two-seater studies. These were seen as a more affordable return to the roots of Thunderbird, which by this time had grown into a much larger four-seater. The idea of a two-seat Mustang was something designers returned to frequently in the period between the original Mustang 1 concept and the 1992 Mach III. Aside from some track-oriented Mustangs that had the rear seats removed to save weight, there has never been a strictly two-seat production Mustang.

Ford Mustangs That Never Were: 1962 Allegro design study

1962 Ford Allegro Design Study
In 1962, the design team, led by Gene Bordinat, worked on several iterations of another design called Allegro. While the production 1965 Mustang was a very different car in almost every visual detail from Allegro, the design study established the basic proportions that would define most Mustangs for the next five decades. The notchback coupe had the same long-hood, short-deck layout with a compact greenhouse that would roll out of the Rouge factory two years later.

Ford Mustangs That Never Were: 1963 two-seat, mid-engine coupe

1963 Ford Two-Seat Mid-Engine Coupe Concept
Although it was probably never seriously considered for production as a Mustang, this hard-top variation of the Mustang 1 concept from 1962 did provide some inspiration for the GT40 MK I that would race at Le Mans and elsewhere beginning in 1964.

Ford Mustangs That Never Were: 1964 two-seater study

1964 Ford Two-Seater Study
This 1964 clay model of a two-seat Mustang incorporates some of the design cues of the production 1965 car including the side scoops.

Ford Mustangs That Never Were: 1965 four-door Mustang

1965 Four-Door Ford Mustang
When you have a product as enormously successful as Mustang, you invariably have to consider how to capitalize on the idea. While Mustang used the platform of the compact Falcon as its starting point, the four-door Mustang could have brought the idea full circle by adding two doors to the pony car. Fortunately for Mustang fans, cooler heads prevailed.

Ford Mustangs That Never Were: 1966 Mustang station wagon

1966 Ford Mustang Station Wagon
In the mid-1960s, Ford designers considered at least a couple of different concepts for a Mustang station wagon, with at least one running prototype based on a 1966 coupe getting built. Another design study included elements for refreshed models that were coming later that decade. All of the known Mustang wagons were three-doors that were closer to a European “shooting brake” than a traditional American family station wagon.

Ford Mustangs That Never Were: 1966 Mach 1 concept

1966 Ford Mach 1 Concept
As the first-generation Mustang transitioned from a pony car to a larger and heavier big-block muscle car, the Mach 1 concept was created as a preview of the 1968 model. The original nose of the concept drew inspiration from the 1963 Mustang II concept.

Ford Mustangs That Never Were: 1966 Mach 1 concept

1966 Ford Mach 1 Concept #2
The Mach 1, as it was shown at the 1967 Detroit Auto Show with a face closer to production Mustangs of the time. The low-cut roofline and racing-type fuel cap never made it to production, but the hatchback did eventually arrive on the 1974 Mustang II.

Ford Mustangs That Never Were: 1967 Allegro II concept

1967 Ford Allegro II Concept
In 1967, Ford designers decided to reprise one of the original Mustang design concepts from 1962 with a new form and repurposed name. Starting with the Avanti/Allegro fastback coupe, the greenhouse was removed and replaced with a low-cut speedster-style windshield, rollbar, flying buttresses on the rear deck and a new rear end. The reworked concept was dubbed Allegro II.

Ford Mustangs That Never Were: 1967 Mach 2 concept

1967 Ford Mach 2 Concept
With the Mustang having already set sales records following its launch in 1964, Ford design chief Gene Bordinat and the Special Vehicles Group decided to try rearranging the pieces for the Mach 2 concept. The 289 Hi-Po V8 was shifted from the front to behind the two seats to evaluate the layout as a possible successor to the Shelby Cobra. Despite its mid-engine layout, the Mach 2 retained the long-hood, short-deck proportions of a Mustang. Unfortunately, the Mach 2 never went much beyond the auto show circuit.

Ford Mustangs That Never Were: 1970 Mustang Milano concept

1970 Ford Mustang Milano Concept
First shown publicly at the February 1970 Chicago Auto Show, the Mustang Milano concept previewed the nearly horizontal rear deck and sharp, extended nose that would be seen on the production 1971 model. However, aside from those two elements, the Milano didn’t really bear much resemblance to any production Mustang. In fact, the car that probably drew most heavily on the Milano profile was the Australian-market Falcon XB coupe of the mid-1970s.

Ford Mustangs That Never Were: 1980 Mustang RSX concept

1980 Ford Mustang RSX Concept
Created at the Italian Ghia design studio, the RSX was conceived as a rally special based on the new Fox-body third-generation Mustang that debuted for the 1979 model year. With a one-inch-wider track and 5.6-inch-shorter wheelbase than the road-going Mustang, the RSX had extra ride height that would be needed for dealing with the off-tarmac stages of European rallies.

Ford Mustangs That Never Were: “Bruce Jenner” design study f

1990 Ford “Bruce Jenner” Design Study
In 1990, Ford designers evaluated a number of themes for a replacement for the long-running third-generation Mustang. The notchback and hatchback bodystyles would be replaced with a single fastback coupe format. After departing from many of the original design cues on the third-generation models, the upcoming fourth-generation would return elements like the galloping pony in the grille, the side scoops and the tri-bar taillamps. This softer concept, known as “Bruce Jenner” wasn’t considered aggressive enough to be a Mustang.

Ford Mustangs That Never Were: “Rambo” design study for four

1990 Ford “Rambo” Design Study
This alternative proposal to the “Bruce Jenner” design study dubbed “Rambo” was deemed too extreme for production.

Ford Mustangs That Never Were: 1992 Mach III concept

1992 Ford Mustang Mach III Concept
The Mach III provided the first public hints of the new design direction that was coming for the fourth-generation Mustang. While classic elements like the grille pony badge, side scoops and tri-bar taillamps were included on the 1994 Mustang, the two-seater layout and the low-cut speedster windshield have never been part of a regular production Mustang.


2005 Mustang Concept
This concept looks almost identical to the production 2005 Mustang with a few exceptions like the hood, front fascia, fog lights and interior.
