The Oldsmobile 98 (originally Series 90; a.k.a. Ninety-Eight) was a full-size automobile and the flagship model of the Oldsmobile division of General Motors. It was introduced for model year 1941 and continued production until 1996.
As 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.
With the introduction of the Aurora a year earlier, the Ninety-Eight was discontinued for 1996, ending production on May 31 1996.
