This model year also holds historical significance as the first to feature the now-famous Barracuda fish logo, a symbol that would become synonymous with Mopar performance in the years to come. The fastback body style, with its sweeping rear glass, was a distinctive feature that set the Barracuda apart from its competition.
Commando V-8 Power and Four-Speed Fun: Engine and Performance: This Barracuda Formula S is powered by a 273 cubic inch Commando V-8 engine, factory rated at 235 horsepower. This small-block V-8 was a potent option for the Barracuda, offering a good balance of power and relatively light weight, contributing to a spirited driving experience. The inclusion of a 4-speed manual transmission is particularly significant, as it allowed drivers to fully exploit the engine’s capabilities and provided a more engaging and спортивний feel. Being one of only 2,970 Barracuda models equipped with this transmission in 1966 further adds to its rarity and desirability among collectors who appreciate the direct connection between driver and machine.
Formula S Performance Enhancements: The Formula S package on the 1966 Barracuda included more than just a potent engine. It typically featured upgraded suspension components, a Sure-Grip differential, and specific badging, all aimed at enhancing the car’s handling and performance capabilities. While the specific details of these enhancements on this particular vehicle are not provided, the Formula S designation itself indicates a focus on a more спортивний driving experience compared to the standard Barracuda.
A Rare and Collectible Early Barracuda: This 1966 Plymouth Barracuda Formula S Fastback represents a rare and collectible piece of early Mopar muscle car history. Its low production numbers, especially when equipped with the 4-speed manual transmission, make it a sought-after vehicle for enthusiasts.
