The Plymouth Barracuda is a two-door car that was manufactured by Plymouth from the 1964 to 1974 model years.
The first-generation Barracuda, a fastback A-body coupe based on the Plymouth Valiant, had distinctive wraparound back glass and was available from 1964 to 1966.
The second-generation 1967 to 1969 Barracuda, though still Valiant-based, was heavily redesigned. Second-generation A-body cars were available in fastback, notchback, and convertible versions.
The third-generation 1970 to 1973 E-body Barracuda, no longer Valiant-based, was available as a coupe and a convertible, both of which were very different from the previous models. The final model year for the Barracuda was 1973. Although a prototype of the Plymouth Cuda was introduced as a concept in 1974, it was never produced.
The redesign for the 1970 Barracuda removed all its previous commonality with the Valiant. The original fastback design was deleted from the line and the Barracuda now consisted of coupe and convertible models. The all-new model, styled by John E. Herlitz, was built on a shorter, wider version of Chrysler's existing B platform, called the E-body.[ Sharing this platform was the newly launched Dodge Challenger; however no exterior sheet metal interchanged between the two cars, and the Challenger, at 110 inches (2,800 mm), had a wheelbase that was 2 inches (51 mm) longer than the Barracuda.
The E-body Barracuda was now "able to shake the stigma of 'economy car'." Three versions were offered for 1970 and 1971: the base Barracuda (BH), the luxury oriented Gran Coupe (BP), and the sport model 'Cuda (BS). Beginning mid year 1970, and ending with the 1971 model, there also was the Barracuda Coupe (A93), a low-end model which included the 198ci Slant Six as a base engine, lower grade interior, and (like other Coupe series Chrysler Corp. offered that year) had fixed quarter glass instead of roll-down rear passenger windows. The high-performance models were marketed as 'Cuda deriving from the 1969 option. The E-body's engine bay was larger than that of the previous A-body, facilitating the release of Chrysler's 426 cu in (7.0 L) Hemi for the regular retail market
