The 1962 model featured new "C" pillar styling for all models except the 4-door hardtop. Sport Coupe models now featured the "convertible roof" styling, shared with other GM "B" full-size hardtop coupes. This style proved extremely popular, and contributed to the desirability of the 19621964 Impalas as collectibles. The "overhang" roof style of the sedans was replaced with a more attractive, wider "C" pillar with wraparound rear window. Engine choices for 1962 settled down, the 348-cubic-inch (5.7 L) V8 discontinued and replaced by the 380 brake horsepower (280 kW) 409-cubic-inch (6.7 L)or 409 bhp 409 cubic inch engine. These engines could only be ordered with a manual shift transmission. The small-block 283 was offered with a two barrel carburetor. The 283 was also enlarged to 327 cubic inches (5.4 L),offered in two versions, one with 250 brake horse power and one with 300 brake horse power, which added more engine choices for small-block fans. The Beach Boys produced a hit single, "409," referring to the Chevrolet, which became an iconic song for these cars. Impalas again featured premium interior appointments, plusher seats pillar mounted seat belts as well as lap belts also this could be done by the dealerships on customer request.And more chrome trim outside, including a full-width aluminum-and-chrome panel to house the triple-unit taillight assembly. Super Sport (SS) models featured that panel in a special engine-turned aluminum, which was also used to fill the side moldings, making the SS more distinctive in appearance. Impala also gains the top station wagon after the Chevrolet Nomad is gone. Due to reliability problems, the optional Turboglide automatic transmission was discontinued, leaving Powerglide the only automatic transmission available until 1965. A new radio was optional.
