Oldsmobile built its biggest full-size car in 1971 although wheelbase was unchanged from 1970.
The 98s were the roomiest Oldsmobiles ever built thanks to the new GM full-size bodies which, at 64.3" front shoulder room and 63.4" rear shoulder room, set a record for interior width that would not be matched by any car until the full-size GM rear-wheel drive models of the early to mid-1990s. The 1971 through 1976 Ninety-Eight was very similar to the Oldsmobile 88 (which by now was called the "Delta 88") except the Ninety-Eight had a longer passenger compartment owing to its 3" longer wheelbase, and had rear Cadillac-esque tailfins to better differentiate between the two full-size models.
The standard 455 cubic-inch Rocket V8 was rated at 320 hp (239 kW) and designed to run on lower octane regular lead, low-lead or unleaded gasoline for the first time this year thanks to a General Motors-mandate that all engines be designed to run on such fuels in preparation for the catalytic converter equipped cars of 1975 and later years that absolutely required unleaded gasoline. Despite this, a few 1975 and 1976 Ninety Eights were released from this catalytic converter requirement in Canada and were given certification along with exemption from requiring unleaded gasoline. V8s were progressively detuned as production wore on in line with tighter emission standards. Trunk mounted louvers for the flow through ventilation system were only found on 1971 models (as in many other GM models of 1971). The louvers were moved to the doorjambs for 1972-1976 models. From 1971 to 1976, Oldsmobile's full-sized Custom Cruiser station wagon shared the 127.0-inch (3,230 mm) wheelbase and 455 cubic-inch V8 with the Oldsmobile 98, and shared its interior and exterior styling, in particular the 98's distinctive front fascia and rear quarter panels complete with fender skirts.
The number of body styles was reduced to four for 1971. The convertible was gone as were the 4-door sedan body styles. A new body style was the Luxury Coupe. For the first time ever all Oldsmobile 98s were now hardtops, and for the first time since 1964 not all hardtops were called Holidays. Standard equipment included armrests, front and rear, power brakes with front discs, electric clock, carpeting, inside hood release, lamp package, power seat, power steering and Turbo-Hydramatic transmission. Standard tire size was J78-15. Interiors were vinyl, cloth and leather. Ninety-Eights were built in both Linden and Lansing.
Four body styles were offered in the 98 series for 1972. Standard equipment included: Deluxe armrests, dual ashtrays, power brakes with front discs, electric clock, carpeting, interior hood release, remote control outside mirror, molding package, interior light package, windshield radio antenna, power seat, power steering, spare tire cover and Turbo-Hydramatic transmission. A midyear version of the 4-door hardtop named the Regency was produced to commemorate Oldsmobile's 75th year as an automaker. For the first time in 17 years the 98 set a new sales record of 121,568.
In 1973 a five body style 98 series was at the top end of the Oldsmobile line. The 75th anniversary Regency 4-door hardtop continued, following its successful mid-1972 introduction. Standard equipment included: Deluxe armrests, dual ashtrays, power brakes with front discs, cigarette lighter, carpeting, inside hood release, dome light, molding package, windshield radio antenna, foam sheet cushions, power steering, Deluxe steering wheel, Turbo-Hydramatic transmission and wheel opening covers. Standard tire size was L78-15. Upholstery was vinyl or cloth. The Oldsmobile 98 set another record of 138,462 sold.
The 1974 Ninety-Eight was now Oldsmobile's longest running series dating back to 1941, and was still popular. Five models were offered with the Regency Coupe taking the place of the Luxury Coupe. Standard equipment included: power brakes with front discs, cigarette lighter, electric clock, interior hood release, lamp package, molding package, remote control outside mirror, windshield radio antenna, power steering, Deluxe steering wheel, spare tire cover, power windows, power seat and Turbo-Hydramatic transmission. Standard tire size was J78-15. Upholstery was vinyl, cloth or leather.
From 1974 to 1975 the 98 reached a record length of 232.4 in (5903 mm), when federally mandated 5 mph (8.0 km/h) bumpers were added both front and rear increasing the overall length of the cars by several inches, while 1976 model year saw minimal length reduction to 232.2 in (5898 mm). It is also worth to note that 1974 Oldsmobile 98 4-door hardtop was the longest car with that body style sold that year, since the longer Lincoln Continental, Cadillac Sixty Special and Cadillac Series 75 were basically sedans (and 1974 Lincoln Continental came only with one hardtop body style: the 2-door). The 1974-76 Oldsmobile Ninety-Eight (as well as all full-size Oldsmobiles, Buicks and Cadillacs) also were among the first US production cars to offer an air bag option ("Air Cushion Restraint System") beginning in 1974. Very few cars were so equipped. The high cost ($700) plus public uncertainty about the yet-to-be proven safety systems that are now universal in today's automobiles saw quite handily to that.
The number of 98 body styles was reduced in 1975. Four were available consisting of coupes or 4-door hardtops in Luxury or Regency trim. Two door models were no longer hardtops. Standard equipment included: power brakes with front discs, cigarette lighter, electric clock, electronic ignition, hood release, bumper impact strips, lamp package, 455 CID engine, molding package, remote-controlled outside mirror, power seat, power windows, power steering, Deluxe steering wheel, chrome wheel discs and Turbo-Hydramatic transmission. Standard tire size was J78-15. Upholstery was vinyl, cloth or leather.
In 1976 the Luxury and Regency editions of the full-size 98s were offered, in 2-door coupes or 4-door hardtops. 4-doors had an extra window (like an opera window) in the C-pillar. A landau roof option for the coupe gave it a huge-looking opera window. Like the Custom Cruiser, 98s had a dual section eggcrate-design grille, with new front end panel, front bumper, and wraparound horizontal parking lamps. Amber marker lenses aligned with the headlamps wrapped around the fender sides. Separate clear cornering lamps had horizontal ribs. Vertical tailamps were decorated with a small emblem in each lens. Tiny back-up lamps stood alongside the license plate, on a panel that also contained small red lenses next to the tailamps. Standard 98 equipment included a 455 CID Rocket V8 with 4-barrel carburetor, Turbo-Hydramatic, vari-ratio power steering, power brakes, power driver's seat, driver's door armrest control console, electronic message center, electric clock, fold-down center armrests, front ashtray, and JR78 x 15 blackwall steel-belted radials. Rear fender skirts and bumper impact strips were also standard. A new 2.41:1 axle ratio became standard to improve fuel economy.
Ninety-Eight Regency
For the 1972 model year, the Limited Edition Regency was offered to commemorate Oldsmobile's 75th anniversary. Each 1972 Oldsmobile Ninety-Eight Regency was registered at Tiffany's and included the specially styled interior with a black or covert "pillow effect" velour upholstery, and power split bench seat, in place of the power bench seat with rear clock. Tiffany touches include the Tiffany Gold paint (an exclusive custom metallic color created especially for this car), the clock has also been specially styled by Tiffany's and bears a white Oldsmobile emblem above the Tiffany's name on a golden face. Each 1972 Regency owner received a distinctive sterling silver key ring as a gift, if ever lost the keys could be dropped in a mail box, and Tiffany's would return them to the owner. A total of 2,650 75th anniversary Ninety-Eight Regencys were built, all of them four-door hardtops. In 1973 the non-anniversary Regency stayed in the line up slotted just above the LS. The Regency package would remain available on the Ninety Eight throughout the 1996 model year when it would become a separate model nameplate.
