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 popular. The "overhang" roof style of the sedans was replaced with a wider "C" pillar with wraparound rear window. Engine choices for 1962 included the 348-cubic-inch (5. 7 L) V8 discontinued and replaced by the 380 bhp (283 kW) 409-cubic-inch (6. 7 L) or 409 bhp (305 kW) 409-cubic-inch (6. 7 L) 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-inch (5. 4 L), offered in two versions, one with 250 bhp (186 kW) and one with 300 bhp (224 kW), 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 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. The Impala also gained the top trim station wagon body design, in place of the Chevrolet Nomad model. 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.
