1970 Plymouth 'Cuda convertible

The short-lived 1970-1971 Plymouth Barracuda Convertibles were part of the automaker's third-generation ponycar line, offered only for these two years. They were rebodied like the hardtop models for 1970 with husky yet clean lines to make room for big-block Chrysler V-8s up to the torquey 440 and ferocious 426 Hemi.

The performance-oriented 'Cuda became a separate series, offering a standard 375-horsepower 383. But these heavier engines made for piggish handling, and the 'Cudas were a bit overdecorated even for muscle machines.

More tasteful were the base and new luxury Gran Coupe series with standard slant six and V-8 options of 318, 340, and 383 cid; the latter provided more than sufficient go. Only detail styling, mechanical, and equipment changes were made for '71, but production slipped in a faltering ponycar market.

The convertibles were never high-demand items, making them quite rare today. Notchback coupe companions carried on through 1974, after which Barracuda was abandoned, a victim of the first energy crisis.
