The Chevrolet Malibu Second generation 1968–1972

The Chevrolet Malibu Second generation 1968–1972

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-cubic-inch (5.0 L) V8 rated at 200 horsepower (150 kW) that replaced the 283-cubic-inch (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, 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.

New grilles and rear decks with revised taillights highlighted the 1969 Malibus and other Chevelles. Instrument panels were revised and front seat headrests were now standard equipment due to federal safety mandate. The ignition switch moved from the instrument panel to the steering column and also doubled as a steering wheel lock. The 307 continued as the base V8 but the 327 engines were replaced by new 350-cubic-inch (5.7 L) V8s of 255 and 300 horsepower (190 and 220 kW). GM's three-speed Turbo Hydra-Matic transmission, previously only offered on SS-396 Chevelles, was now available on all models with all engines including the six-cylinder and small-block V8s which in previous years were only available with the two-speed Powerglide.

For 1970, the Malibu was initially the only series of Chevelles offered, aside from the SS-396 and new SS-454, as the low-line 300 and 300 Deluxe models were discontinued, which also eliminated the two-door pillared coupes from the Chevelle lineup – which were never included in the Malibu series. New grilles, rear decks with taillights moved into the bumper and revised Sport Coupe roofline highlighted this year's changes. The standard six-cylinder engine was punched up from 230-to-250-cubic-inch (3.8 to 4.1 L) and 155 horsepower (116 kW), while the same assortment of V8s carried over with the addition of a 330 horsepower (250 kW), 400-cubic-inch (6.6 L) V8 on non-SS Chevelles. At mid-year the Malibu was rejoined by lower-line Chevelle models that were simply called the base Chevelle in both four-door sedan and two-door hardtop.

In 1971, Malibus and all other Chevelles got a new grille surrounded by single headlamps replacing the duals of previous years and four round taillights similar to Camaros and Corvettes were located in the bumper. All engines were detuned to use lower-octane unleaded gasoline this year per GM corporate policy as a first step toward the catalytic converter equipped cars planned for 1975 and later models which would require no-lead fuel.

Only new grilles highlighted the 1972 Malibu and other Chevelles. All bodystyles were carried over from 1971 but 1972 would be the final year for hardtops and convertibles as the redesigned Chevelles originally planned for this year, but delayed until 1973, would feature Colonnade styling with side pillars and frameless door windows.
