What was the Oldsmobile Ninety-Eight?
The Ninety-Eight was Oldsmobile’s full-size luxury car and flagship, known for its roomy, comfortable character. Earlier versions came in more than one body style; the later generations were large sedans with front-wheel drive. The name dates back to the early years of the marque and remained part of Oldsmobile’s range until 1996.
Ninety-Eight generations
The X generation ran from 1977 to 1984, followed by the XI from 1985 to 1990 and the XII from 1991 to 1996. The last two generations used GM’s C-body platform. Over that period, the Ninety-Eight adapted to the move toward front-wheel drive while keeping its place as Oldsmobile’s largest, most luxurious car.
Engines and power
In the United States, the range covered engines from 3.0 L to 5.7 L, with petrol and diesel options. Canadian versions used a 3.8 L petrol engine.
How economical was the Ninety-Eight?
US EPA figures show a best combined rating of 24 MPG and a lowest stated consumption of 9.8 L/100 km. In Canada, the 3.8 L petrol versions are rated at 11.5 L/100 km on the NRCan five-cycle test. WLTP or NEDC results in Europe, EPA figures in the United States and five-cycle results in Canada use different procedures, so the figures are best read within their own markets.
