The Impala SS became its own series (separate model rather than an option package) for 1964 and continue to feature unique exterior trim and a lavish interior. A slight redesign distinguished the 1964 Impala giving the car a more boxy formal look. The Impala SS received different side moldings which ran along the body side sculpturing. The usual red-filled SS letters on the rear fenders did not use the Impala emblem. The SS models got the aluminized taillight panel insert and additional SS identification on the right side of the trunk. The new wheel covers did not have the nonfunctional knock-off spinners. Available only as a convertible or Sport Coupe the SS was offered with the same engines as 1963 including the top of the line 409 except the 427ci 2x4bbl 430hp V-8 was dropped. But the introduction of the Pontiac GTO would steal the Impala SS thunder as buyers began to shift over to smaller lighter cars that could offer similar performance for less money than the full size car. Prices ranged from $2671-$3196. Weights were approximately 3325-3895 lbs.
