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 , had a wheelbase that was longer than the Barracuda.
