Mopar fans will gleefully point out that Ford's "original pony car" was actually beaten to the showroom floor by Plymouth's offering in the youthful sporty coupe category, the Barracuda. (Maybe the category should be called fishy cars?)
This was possible because the Mustang was one of the most poorly-kept secrets in Detroit and, while it relied heavily on shared mechanicals with the compact Falcon, the Barracuda was simply a Valiant hardtop coupe with a new glass fastback and bucket seats.
Like the Valiant (and the Mustang, for that matter) the base engine in the Barracuda was a thrifty inline six. For 1966 this meant the bulletproof 225 cubic inch Slant Six rated at 145 horsepower, with an optional 273 cubic inch V-8 breathing through a single 2-barrel carb and single exhaust, making 180 ponies.
The performance-oriented Formula S model got the four-barrel, dual-exhaust Commando 273 V-8, which had a 10.5:1 compression ratio and put out 235 gross horsepower. Formula S buyers could get a floor-shifted four-speed manual or three-speed automatic.
Car and Driver tested a Formula S with the three-speed auto and 3.23 rear end. They clocked a zero-to-sixty time of 9.1 seconds and a 17.6 quarter at 81mph through the traps. With an auto transmission, front disc brakes, and factory racing stripes, the well-optioned test car stickered at $3,011.81 which is about $31,000 in today's dough.
Alas, the purple color on this one is a repaint job. "In Violet" wouldn't be a factory Barracuda color for another few years.
This one was photographed with a Canon EOS R5 and an RF 24-240mm f/3.5-6.3 zoom lens in June of 2026.
