Malibus and all other Chevelles were completely restyled for 1968 with semi-fastback rooflines on two-door hardtops and wheelbases split to 112 inches (2,800 mm)} on two-door models and 116 for four-door sedans and station wagons. Engine offerings included a new 307 cu in (5. 0 L) V8 rated at 200 hp (149 kW; 203 PS) that replaced the 283 cu in (4. 6 L) 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 Concours 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, a center console and floor shifter (only with the hardtop and convertible, which was shared with the SS396) 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.
