The 1966 Plymouth Valiant was a popular compact car that offered a wide range of body styles and trim levels, including the V-100, V-200, Signet, and Barracuda. The Valiant V-100 and V-200 were the standard models, available as two-door sedans, four-door sedans, and station wagons. The V-100 featured a basic trim level, while the V-200 offered more luxurious features, such as vinyl upholstery and chrome accents. The Signet was a two-door hardtop coupe that offered a sportier appearance, while the Barracuda was a high-performance muscle car that became a legend in its own right. All models shared the same basic platform, which included a unibody construction with a sturdy suspension and brakes. However, they differed significantly in terms of their powertrains, styling, and features.

The 1966 Valiant V-100 and V-200 were powered by a 170 cubic-inch (2.8-liter) six-cylinder engine, which produced 101 horsepower. The Signet offered the same engine, but with a slightly higher output of 110 horsepower. The Barracuda, however, was available with a variety of engines, including a 273 cubic-inch (4.5-liter) V8 that produced 145 horsepower. This made the Barracuda a formidable performer, especially when paired with its optional four-speed manual transmission. The base Valiant models were known for their fuel efficiency and affordability, making them popular choices for families and commuters. The Signet offered a touch of style and luxury, while the Barracuda appealed to those who craved performance and excitement. The 1966 Plymouth Valiant was a successful model year for the brand, thanks to its versatility, reliability, and attractive pricing.
