Sixth generation (1965–1970)

The Delta name in 1965 was a luxury trim line of the Dynamic 88, the Dynamic 88 Delta, which replaced the previous top-series B-body Olds, the Super 88. The first 65s were known as the Dynamic 88 Deltas, But within a few weeks after the start of the model year, Olds began marketing the line as a separate series known as the Delta 88. Other lines of full-size Oldsmobile models included the low-priced Jetstar 88, the high-volume Dynamic 88 from sales, the sporty Jetstar I and the sporty, luxurious Starfire, all on a 123-inch (3.124 mm) wheelbase.

All 1965 Olds models featured completely new styling and engineering. B-body cars featured more rounded styling than previous years with Coca-Cola bottle profiles and semi-fastback roof lines on Holiday coupes (two-door hardtop) – Jetstar I and Starfire coupes got a variation more rounded of the square 1963-64 roofline with concave rear window shared by the Pontiac Grand Prix. Also introduced this year was a new 425-cubic-inch Super Rocket V8 with horsepower ratings ranging from 300 to 370 depending on carburetion and compression ratio. The new Turbo Hydramatic three-speed transmission with torque converter replaced the Roto Hydramatic used since 1961. Another addition to the list of options for 1965 on all B-body cars was a four-speed manual transmission with a Hurst shifter, which it was rarely an ordered offering.
1966 Oldsmobile Delta 88 Holiday Sedan

Few styling changes other than revised grills and tail sections marked the 1966 full-size Oldsmobiles. The Jetstar I sports series was dropped with a lower-priced Starfire that was only offered as a hardtop coupe instead. . All 88 models from the other series were carried over from 1965 with a new convertible added to the Delta 88 lineup and the same body style was removed from the Jetstar 88 line.

A new option for all senior Oldsmobiles (88, Ninety-Eight and the new front-wheel drive Toronado) was GM’s automatic Comfortron air conditioning system first introduced by Cadillac in 1964. Comfortron allowed the driver to automatically set a constant temperature. throughout the year. level. The basic Frigidaire air conditioning unit offered in previous years continued as before and became an increasingly popular option on full-size Oldsmobiles. Another new option for 1966 was a tilt-and-telescope steering wheel that could be adjusted vertically to six different positions, as well as telescopically outward from the instrument panel to enhance driver comfort.

For 1967, all full-size GM cars received a mid-cycle makeover that included fuller body panels. Rounder styling cues marked all 1967 Olds 88 models that received longer hoods and shorter tires and wider roof lines and fastbacks on 88 Holiday coupes to emulate the styling of Olds’ front-wheel drive flagship, the Toronado. . Olds 88 received a three-part front grill made of a central bow flanked on both sides by headlight pods. For the first time since 1959, the dual headlights were divided by parking lights. The taillights on the 88s featured a cascading pattern. Interiors made extensive use of wood-tone paneling and shiny metal finishes were kept to a minimum.

As for the model, there was more juggling of names. The Delmont 88 was introduced in 1967 and was produced for only two years, replacing the Jetstar 88 and Dynamic 88 model lines. The Delmont included the 330 V8 as standard and the 425 V8 as an option in 1967 and the new “Rocket 455” version. of the same engine in 1968. The 425 was standard on the Delta 88. The Delta 88 gained a new subseries. called the Delta 88 Custom, which had a more luxurious interior than the standard Delta 88 with a Strat bench seat in the Holiday Sedan (four-door hardtop) or, in the Holiday Soupe (two-door hardtop), a choice of Strato individual seats with console or Strato bench with armrests. The Delta Custom Holiday Coupe was essentially a successor to the old 88-based Starfire series offered in previous years (1961–66) but with a standard 88 semi-fastback roofline instead of the square roof of the Starfire with a concave rear window. Another styling cue for the Delta Custom was the addition of a second set of taillight reflectors positioned at the bottom of the bumper.

New options for 1967 included front disc brakes, 8-track stereo tape player, and a control system.
