The Plymouth Barracuda is a two-door car that was manufactured by the Plymouth division of the Chrysler Corporation from 1964–1974.
The first-generation Barracuda, a fastback A-body coupe based on the Plymouth Valiant, had a distinctive wraparound back glass and was available from 1964–1966.
The second-generation 1967–1969 Barracuda, though still Valiant-based, was heavily redesigned. Second-generation A-body cars were available in fastback, notchback, and convertible versions.
The 1970–1974 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 1974.
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 also the newly launched Dodge Challenger; however, no sheet metal interchanged between the two cars and the Challenger, at 110 inches, had a 2 in (51 mm) longer wheelbase than the Barracuda, at 108 inches.
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). In 1971 only, there also was a low-end model called the Barracuda Coupe, which (like other Coupe series Chrysler Corp. had in 1971) had a fixed rear passenger window and minor B pillar 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.
For 1970 and 1971, the Barracuda and Barracuda Gran Coupe had two six-cylinder engines available — a new 198 cu in (3.2 L) version of the slant-6, and the 225 — as well as three different V8s: the 318ci, the 383ci with 2-barrel carburetor and single exhaust, and the 383ci with 4-barrel carburetor and dual exhaust 330 hp (250 kW) SAE gross. The Cuda had the 383ci 335 hp (250 kW) SAE gross (same as Dodge's 383 Magnum) as the standard engine. It also had the 440ci 4-barrel Super Commando, the 440ci 6-barrel Super Commando Six Pak, and the 426ci Hemi. The 440- and Hemi-equipped cars received upgraded suspension components and structural reinforcements to help transfer the power to the road.
