The Plymouth Barracuda is a two-door pony car manufactured by Plymouth from 1964 to 1974.
The third generation, offered from 1970 to 1974, was no longer based on the A-body, but on the Chrysler E-body. The completely new design was similar to the Dodge Challenger and available in hardtop and convertible body styles. The Barracuda was discontinued after the 1974 model year.
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 (2,794 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’.”

The Valiant was totally reskinned for 1963 with a 0.5 in (13 mm) shorter wheelbase; it had a wide, flat hood and a flat square rear deck. The upper belt feature line ran from the rear body, in a gentle sweep, to the front fender tip. Here it was ‘veed’ back and down to the trailing edge of the front fender. The roofline was flatter and sharpened in profile. The grille was a variation of the inverted trapezoid shape that characterized contemporary Chryslers, with a fine mesh insert.
