1964 Chevrolet Impala SS Convertible

The Chevrolet Impala is a full-sized car built by Chevrolet for model years 1958 to 1985, 1994 to 1996, and 2000 to 2022. The Impala was Chevrolet's popular flagship passenger car and was among the better-selling American-made automobiles.

For 1964, the Impala was restyled to a more rounded, softer look. The signature taillight assembly had an "upside-down U" shaped aluminum trim strip above the taillights, but the individual lights were surrounded by a body-colored panel.

In a December 17, 1960, press release, Chevrolet introduced the Impala SS (Super Sport) option to the market. The SS badge was to become Chevrolet's signature of performance on many models, though it often has been an appearance package only. The Impala's factory SS package in 1961 was truly a performance package when so equipped from the factory with both the trim and "mandatory" suspension and engine upgrades, beginning with the 348 cu in (5.7 L) V8 engines available with 305 hp (227 kW; 309 PS), 340 hp (254 kW; 345 PS), and 350 hp (261 kW; 355 PS) or the new 409 cu in (6.7 L) V8, which in 1961 was rated at 360 hp (268 kW; 365 PS). Unlike all other years, the 1961 Super Sport package was available on any Impala, including sedans and station wagons (the sales brochure shows a 4-door hardtop Sport Sedan with the SS package). The package also included upgraded tires on station wagon wheels, springs, shocks and special sintered metallic brake linings. Only 142 1961 Impala Super Sports came from the factory with the 409. In addition to the factory-installed SS package, Chevrolet dealers could add SS trim to any standard Impala without the "mandatory" performance upgrades, and a number of 1961s were so equipped.
