Redesigned in 1965, the Impala set an all-time industry annual sales record of more than 1 million units in the US. All new full-size Chevrolets eschewed the "X" frame for a full-width perimeter frame, a new body that featured curved, frameless side glass (for pillarless models), sharper angled windshield with newly reshaped vent windows, and redesigned full-coil suspension.

The 1967 model was redesigned with enhanced Coke bottle styling that featured Corvette-inspired front and rear fender bulges. The curves were the most pronounced with the 1967–1968 models. In keeping with federal regulations, safety features were built into Impalas during the 1967 and 1968 model years, including a fully collapsible energy-absorbing steering column, side marker lights, and shoulder belts for closed models. The L72 engine was not available in 1967, but a L36 Turbo-Jet V8 was optional.

The 1969 model year Impala production topped Caprice production by 611,000 units. Impala station wagons were renamed Kingswood, a name which would continue through 1972. The similar 1970 Impala got a minor facelift featuring a more conventional under the grille bumper replacing the wrap-around unit used in 1969 along with new triple vertical taillights in the rear bumper. Canadian buyers got the choice of a lower priced companion to the Impala Sport Coupe, the Bel Air Sport Coupe, which used the same body but featured Bel Air trim.
