For the 1978 model year, the Malibu name, which had been the best-selling badge in the lineup, replaced the
Chevelle name. This was Chevrolet's second
downsized nameplate, following the lead of the 1977
Chevrolet Caprice and
Impala. The new, more efficient platform was over a foot shorter and had shed compared to previous versions, yet offered increased trunk space, leg room, and head room. Only two trim levels were offered: Malibu and Malibu Classic. The Malibu Classic Landau series had a two-tone paint job on the upper and lower body sections, and a vinyl top. This generation introduced the
Chevrolet 90° V6 family of engines, with the 200 CID (3.3 L) V6 as the base engine for the all-new 1978 Malibu, along with the 229 CID (3.8 L) V6 and the 305 CID (5.0 L) Chevrolet V8 as options. The 200 and 229 engines were essentially a small-block V8 with one pair of cylinders removed. The front and rear bellhousing face were the same as the small V8. The 231 engine was a Buick product, and featured a front distributor. Three bodystyles were produced (
station wagon,
sedan, and
coupe), and the design was also used as the basis for the
El Camino pickup truck with its own chassis. The sedan initially had a conservative six-window
notchback roofline. This was in contrast to the unusual fastback rooflines adopted by Oldsmobile and Buick divisions which would later revert to a more formal pillar style. To increase rear seat hip room (and encourage more orders for the high-profit air conditioner), the windows in the rear doors of four-door sedans were fixed, while the wagons had small moveable vents. With the rear window regulators no longer required, Chevrolet was able to recess the door arm rests into the door cavity, resulting in a few extra inches of rear seat room. Customers complained about the lack of rear seat ventilation. This design undoubtedly contributed to the number of factory air-conditioning units sold with the cars, to the benefit of General Motors and Chevrolet dealers. For the 1981 model year, sedans adopted a four-window profile and "formal" pillared upright roof line. The two-door coupe was last produced in this year, as the
Monte Carlo assumed the market position held by the 2-door coupe. For 1982 the Malibu was facelifted with more squared-off front styling marked by quad headlights with long, thin turn signals beneath them. The look was reminiscent of the also recently facelifted Chevrolet Caprice. For 1983, Malibus gained a block-style "Malibu" badge on the front fenders to replace the cursive-style script located on the rear quarter panels of previous model years. The four-door Malibu was commonly used in fleet service, especially for law enforcement. After the
Chevrolet Nova ceased production in 1979, the
mid-sized 9C1 police version (not to be confused with the full-size
Chevrolet Impala 9C1 which was also available) was transferred to the Malibu, filling a void for the
mid-sized police patrol cars. A 9C1-equipped Malibu with an LT-1 Z-28 Camaro engine driven by
E. Pierce Marshall placed 13th of 47 in the 1979
Cannonball Baker Sea-To-Shining-Sea Memorial Trophy Dash, better known as the Cannonball Run. There was no factory Malibu SS option available on this generation. The SS only came in the
El Camino. The rare, and striking, 1980 Malibu M80 was a dealer package for only North and South Carolina. It was mostly aimed at NASCAR fans who regularly traveled to Darlington Raceway. To this day, the number actually produced is unknown; estimates place this around 1,901 cars. All M80s had to be white with dark blue bucket seats and center console interior. The base of the M80 was a two-door sport coupe equipped with the F41 Sport Suspension package and the normal V8 (140 hp) drivetrain. The M80 option added two dark-blue skunk stripes on top and a lower door stripe with the M80 identification. The package also added front and rear spoilers and 1981 steel rally wheels (sourced from the 1980 Monte Carlo). In Mexico, General Motors produced this generation at the
Ramos Arizpe plant, which was sold during three years (1979 to 1981). Mexican versions came in three trim levels (Chevelle, Malibu and Malibu Classic) and two body styles (sedan and coupe) with the I6 as basic engine and the V8 as the optional; this engine was standard on Malibu Classic models during those three years. This was possible because the Mexican emissions regulations remained relatively loose at the time.
Iraqi taxi In 1981,
General Motors of Canada (GMCL) produced a special order of 25,500 four-door Malibu sedans at their
Oshawa plant for
Saddam Hussein's
Iraqi government. The deal was reportedly worth $100 million to GMCL. The proffered excuse for the cancellation was dissatisfaction with the cars' quality, notably difficult shifting of the transmission—which GM traced to a clutch release issue that eventually required on-site retrofitting by a crew of Canadian technicians sent to Iraq. Later speculation was that the Iraqis backed out for financial reasons, due to their escalating hostilities with
Iran requiring the immediate diversion of funds to support the Iraqi war effort. GMCL President Donald Hackworth was initially quoted as stating the company would try to sell the Malibus in other Middle East markets, but in the end the orphaned cars were all sold to the Canadian public at the greatly reduced price of about
CA$6,800. Over the years, they have acquired a low-key celebrity status, sometimes being colloquially referred to as "Iraqibu".
NASCAR The Malibu was an extensively used body style in
NASCAR competition from 1973 to 1983. The Laguna S-3 variant, in particular, was successful during the 1975 through 1977 racing seasons, with
Cale Yarborough winning 20 races in those years as well as winning the NASCAR championship one year. Because it was considered a limited-edition model, NASCAR declared it ineligible for competition following the 1977 season, even though (given NASCAR's three-year eligibility rule) it should have been allowed to run through 1979. Beginning in 1981, the downsized Malibu body style was eligible to run, but given its boxy shape only one driver,
Dave Marcis, ran it in 1981 and 1982, with one victory in a rain-shortened
Richmond 400 at
Richmond in 1982, the independent driver's last win.

Production Figures: G platform Beginning in 1982, the Malibu shared GM's redesignated
rear-wheel-drive G platform with cars like the
Pontiac Grand Prix,
Oldsmobile Cutlass Supreme and
Buick Regal. The Malibu Classic was last marketed in 1982; Malibus were produced as four-door sedans and as station wagons until 1983, at which time it was fully replaced by the
front-wheel-drive Chevrolet Celebrity. Although the sedan and wagon were phased out, the
El Camino utility, which shared styling with the Malibu, remained in production until 1987. == Fifth generation (1997) ==
