For 1965, Malibus and other Chevelles received new grilles and revised tail sections but carried over the same basic styling and bodystyles from 1964. The Malibu and Malibu SS models continued as before with the SS featuring a blacked-out grille and special wheelcovers. Top engine option was now a 350-horsepower 327.
The Malibu SS was replaced in 1966 by a new Chevelle SS-396 series that included a big-block 396 cubic-inch V8 engine, heavy duty suspension and other performance equipment. Other SS-396 equipment was similar to Malibu Sport Coupes and convertibles including an all-vinyl bench seat. Bucket seats and console with floor shift were now optional on the SS and for 1966 with the SS now denoting a car with a big-block engine, the bucket seats became a new option on the regular Malibu Sport Coupe and convertible, upon which any six-cylinder or small-block V8 could be ordered. Also new for 1966 was the Chevelle Malibu four-door Sport Sedan hardtop. Styling revisions on all 1966 Chevelles including more rounded styling similar to the full-sized Chevys with sail panels and tunneled rear windows featured on two-door hardtop coupes.
For 1967, the same assortment of bodystyles were continued with styling changes similar to all other Chevelles including a new grille and revised tail section with tailights that wrapped around to the side. New this year was a Chevelle Malibu Concours station wagon with simulated wood trim on the exterior. Front disc brakes were a new option along with a stereo 8-track tape player. Same assortment of drivetrains carried over from 1966 with the top 327 cubic-inch V8 dropped from 350 to 325horsepower (242kW).
Malibus and all other Chevelles were completely restyled for 1968 with semi-fastback rooflines on two-door hardtops and wheelbases split to 112inches (2,800mm) on two-door models and 116 for four-door sedans and station wagons. Engine offerings included a new 307 cubic-inch V8 rated at 200horsepower (150kW) that replaced the 283 cubic-inch V8 that had served as the base V8 since the Chevelle's introduction in 1964. Inside was a new instrument panel featuring round gauges in square pods similar to what would appear in Camaros the following year. New for 1968 was the Concorus luxury option for Malibu sedans and coupes that included upgraded cloth or vinyl bench seats, carpeted lower door panels, woodgrain trim on dash and door panels, and Concours nameplates. There was again a top-line Concours Estate wagon with simulated woodgrain trim that had the same interior and exterior appointments as the Malibu sedans.
