In 1966 a top-line Cutlass Supreme was introduced as a four-door hardtop sedan with a more powerful 330 CID Jetfire Rocket V8 than the regular F-85 / Cutlass models, a more luxurious interior and other trimmings.

The Cutlass was initially the top model of the F-85 line but became a separate model by 1964 with the F-85 nameplate continued only on the lowest priced models through the 1972 model year, after which all Oldsmobile intermediates were Cutlasses.

The existing F-85 models returned, and a convertible was added to the line-up in September, available in both standard and Cutlass versions.

Two-door F-85 and Cutlass models adopted a semi-fastback roofline with a massive rear end.

The 1969 F-85 / Cutlass models received only minor trim changes from their ' 68 counterparts such as a now-Olds trademark split grille with vertical bars and vertical taillights.

New that year was the introduction of price leader for the full-sized Olds series, the Jetstar 88, which used the same basic bodyshell as other 88 models, but shared many of the mid-size car components with the F-85.

It was introduced as an option package for F-85 and Cutlass models sold in the United States beginning with the 1964 model year.

Unlike in previous years which the 4-4-2 option could be ordered on either baseline F-85 or upscale Cutlass models, the 1967 4-4-2 package was based on the top-line Cutlass Supreme series including the sport coupe ( with center post ), Holiday hardtop coupe and convertible.

Generally, interior appointments in Supreme models were more luxurious than lesser F-85 and Cutlass series cars and included a cloth or vinyl notchback bench seat with armrest in sedan models and all-vinyl Strato bucket seats in coupes and convertibles.

In mid-1961, each of three divisions introduced two-door pillared coupes to the line with sportier versions of the Buick and Olds models added including the Special Skylark and F-85 Cutlass, both of which featured bucket seats, custom interior and exterior trim, and more powerful engines.

In Spring of 1962 Chevrolet really committed itself to the sporty image they had created for the Corvair by finally introducing a Convertible version and then offering a high performance turbocharged " Spyder " option for Monza coupes and convertibles, making the Corvair the first production automobile to come with a turbocharger as a factory option, with the Oldsmobile F-85 Turbo Jetfire a few weeks later in 1962.

The F-85 had double wishbone front suspension and a four-link live axle in the rear, suspended with coil springs all around.

The F-85 had drum brakes of diameter.

This engine had been used in the A-body platform Buick Special and Oldsmobile F-85 and was the lightest mass-production V8 in the world, with a dry weight of only, and was about lighter than its 4-cylinder counterpart by the MOWOG ( Morris-Wolseley Garages ) foundry.

The first-year F-85 was offered as a four-door sedan in base or Deluxe trim, or a four-door station wagon with either two or four seats, in base or Deluxe form.

Redesigned base model F-85 and mid-level Vista Cruiser station wagons were also available.

The 1970 Cutlass was available in seven body styles: the base F-85 two-door sedan, as well as two-door hardtops offered in both notchback Cutlass Supreme and fastback Cutlass S and 442 body styles-a practice similar to Ford and Mercury intermediates of that time, which were offered in both notchback and fastback coupes starting in 1968.

The aluminum V8 was replaced by conventional cast-iron block V8s of 300 cubic inches for the Buick Special / Skylark and 330 inches for the Oldsmobile F-85 / Cutlass, while Pontiac carried over its 326 cubic-inch V8 to the ' 64 Tempest / LeMans line while switching the base engine from the four-cylinder to a 215 cubic-inch inline six-cylinder.

The Oldsmobile, dubbed F-85, shared a new A-body platform, using a 112-inch ( 2845 mm ) wheelbase and still-novel unibody construction, with the Buick Special and Pontiac Tempest.

Car Life magazine tested an F-85 with the standard engine and automatic transmission, and recorded a 0-60 ( 0 – 96 km / h ) time of 14. 5 seconds, with a top speed just over.

Overall F-85 sales rose to 97, 382, with the Cutlass displacing the four-door Deluxe sedan as the top-selling model.

Disappointing sales of the compact F-85, along with the introduction of Ford Motor Company's intermediate Fairlane in 1962, prompted GM to enlarge the senior compacts for the 1964 model year.

The new intermediate F-85 now rode a conventional body-on-frame chassis with a perimeter frame.

Base model remained the F-85, with mid-level Cutlass S, and upscale Cutlass Supreme, as well as the 442.

F-85 station wagons without the rooftop glass were also available with a 350 CI engine with a 2 barrel carburetor and two-speed JetAway automatic transmission.

An all-new body and chassis with perimeter " Guard Beam " frame and all-coil suspension replacing the previous leaf springs highlighted the 1961 full-sized Oldsmobiles, which were joined by the new compact F-85.

Priced at $ 285. 14, it was available on any F-85 or Cutlass model except the station wagon, although most were Cutlass hardtop coupés ( Oldsmobile archives indicate that approximately 10 four-door sedans were built with the B09 option ).

In addition to the new body style ( also available on the midline F-85 Deluxe series ), the Supreme featured a plusher interior that included a notchback bench seat with armrest, full wheel covers and deluxe door panels among other items including " CS " emblems on the rear C-pillars and trunk lid.

* The Tempest also used a rear transmission, or transaxle to permit a flat floor, eliminating the driveshaft hump, for improved interior space, while the Buick Special and Olds F-85 used a conventional front engine / front transmission drivetrain.

Its platform was quite similar to the later compact F-85, which was not introduced for seven more years.

Although initially envisioned for the smaller F-85 line, its cost and experimental nature pushed the program towards a larger, more expensive car.

Even more new competitors were squeezing their way into the marketplace, as Dodge brought out the Lancer, and General Motors issued the Buick Special, Oldsmobile F-85 and Pontiac Tempest.

* Oldsmobile 442-began as a 1964 muscle car option package ( 4-barrel carburetor, 4-speed manual transmission, 2 exhausts ) on the F-85 / Cutlass.

But a complete departure in 1961 was the new Tempest, one of the three BOP ( Buick-Olds-Pontiac ) " compacts " introduced that year, the others being the Buick Special and Skylark and Oldsmobile F-85 and Cutlass.

Introduced in 1961 as the top trim level in Olds ' compact F-85 line, over the years the Cutlass name accumulated great brand equity, and became one of the most popular nameplates in the industry in the 1970s.

The F-85 / Cutlass underwent a major body restyle in 1968, as did all other GM A-body cars.

The Vista Cruiser used a six-inch ( 152 mm ) stretched wheelbase version of the intermediate F-85 / Cutlass.

Other sporty bucket-seat compact cars that appeared during the early 1960s included the Mercury Comet S-22, Oldsmobile F-85 Cutlass, Buick Special Skylark, and Pontiac Tempest LeMans.

Sharing the new monocoque ( unibody ) Y platform with the Buick Special and Skylark, and Oldsmobile F-85 and Cutlass, the model also appeared under the LeMans nameplate ( largely beginning with the 1962 model year, though Pontiac also manufactured a few 1961 Le Mans coupes ).

Together with its sister cars ( the Oldsmobile F-85 / Cutlass and Buick Special / Skylark ), the Tempest / Le Mans moved to the new A body platform shared with the new Chevrolet Chevelle, and all three cars received updates and modifications standardizing them throughout — including the wheels — by GM edict.

Interestingly, the success of the GTO prompted Oldsmobile to rush out its own high-performance option package for the F-85 / Cutlass called the 442 that year, and the next year, for Buick to release a high-performance version of the Skylark called the Skylark Gran Sport, or GS.

The W31 option was offered on Supreme coupes only in 1968, but continued on lower-line F-85 and Cutlass S coupes through 1970.
