The Catalina, though it was the lowest-priced full-sized Pontiac, was priced and trimmed below the Chevrolet Impala due to GM's overlapping price structure formula only a step below the Buick LeSabre and Oldsmobile 88 in trim and appointments but priced about $100 to $200 less. Catalinas also came standard with more amenities than Chevrolet models and included a larger and more powerful V8 engine of 389 cubic inches, compared to the Chevy's six-cylinder or 283 and 348 cubic-inch V8s. Pontiacs also benefited from a much better automatic transmission than their Chevrolet counterparts - the four-speed Hydra-Matic - versus the Chevy's two-speed Powerglide.
