The first Allegro was finished in late 1962 and, painted red, was shown with a group of other similarly sized concepts referred to today as Ford’s X-cars. Out of that program came the Mustang II concept, which would go on to influence the production Mustang. About all the Allegro contributed to the production Mustang were elements from its fastback roofline. And that was about all that was seen of the Allegro until 1967, when Ford pulled it out of retirement, sliced off its roof and tacked on some flying buttresses that connected via a basket handle with integrated headrests for the driver and front-seat passenger. (Those flying buttresses, incidentally, appear to come straight off a design study that the Lincoln-Mercury design studio proposed for the Mustang in 1962. Coincidence?) The metallic gold paint remained, but now with a pair of green-gold stripes. Ford simply described it as a contemporary version of the fastback Allegro, and one must presume that the same Falcon chassis that was under the original Allegro supported its predecessor as well. We’ve yet to come across a designer’s name attached to the Allegro II or any mention of the Allegro II’s whereabouts.
We suspect Ford has it stashed away somewhere in Dearborn. Can anybody confirm that suspicion?
