Oldsmobile 98 (5th gen) 1957-1958

The Oldsmobile 98 (spelled Ninety-Eight from 1952 to 1991, and Ninety Eight from 1992 to 1996) is the full-size flagship model of Oldsmobile that was produced from 1940 until 1996. The name — reflecting a "Series 90" fitted with an 8-cylinder engine — first appeared in 1941 and was used again after American consumer automobile production resumed post-World War II. It was, as it would remain, the division's top-of-the-line model, with lesser Oldsmobiles having lower numbers such as the A-body 66 and 68, and the B-body 76 and 78. The Series 60 was retired in 1949, the same year the Oldsmobile 78 was replaced by the 88. The Oldsmobile 76 was retired after 1950. This left the two remaining number-names to carry on into the 1990s as the bread and butter of the full-size Oldsmobile lineup until the Eighty Eight-based Regency replaced the 98 in 1997.

Occasionally additional nomenclature was used with the name, such as L/S and Holiday, and the 98 Regency badge would become increasingly common in the later years of the model. The 98 shared its General Motors C-body platform with Buick and Cadillac.

Since it was the top-line Oldsmobile, the series had the most technologically advanced items available, such as the Hydramatic automatic transmission, the Autronic Eye, an automatic headlight dimmer, and Twilight Sentinel (a feature that automatically turned the headlights on and off via a timer, as controlled by the driver), and the highest-grade interior and exterior trim.

The Oldsmobile line underwent a sweeping reengineering in 1957, with a 3-piece rear window making a reappearance on some models. Once again the 4-door 98's were at the top, this year officially titled Starfire 98. Standard equipment included armrests, turn signals, rubber floor mats, sun visors, front fender chrome script, exposed chrome roof bows, side interior courtesy lights, electric windows, special emblems, power steering, power brakes, and Jetaway Hydramatic. Upholstery choices included a variety of cloth, Morocceen (vinyl), and leather. Standard tire size was 9.00 (229) by 14 inches (356 millimetres). The standard engine was now the 371 cu in (6.1 L) Rocket V8.[12] A safety recessed steering wheel was added. Front leg room was 43.8 inches (1,113 millimetres).

A major styling change was seen in 1958. The Ninety-Eight series again had its own exclusive wheelbase of 126.5 inches while sharing the more powerful Rocket V8 with the Super 88. Four body styles were available. Standard series equipment included four headlights, oil filter, turn signals, printed circuit instrument cluster, aluminum anodized grille, padded dash, foam rubber padded seat cushions, courtesy lights, parking brake light, special side moldings, chrome rocker panel moldings, Jetaway Hydramatic transmission, power steering and brakes, dual exhaust, electric clock, color accented wheel discs, and chrome wheel frames. Interiors could be ordered in a variety of colored leathers, cloth, and Morocceen. Standard tires were 8.50 (216) by 14 inches (356 millimetres). Air suspension was added as an option. Also new was a speed warning device, which could be set towards a certain speed and when the limit was reached, a buzzer would sound, alerting the driver of the vehicle to slow down.
