Oldsmobile Aurora
The Aurora was the car supposed to save Oldsmobile, and it was a sports car. Cramming a V8 engine under the hood of a small car seemed to be what GM did best during this era. The problem with Aurora was that it didn’t seem to catch on with consumers. The styling was too extreme and the price tag was high (via Cars).
That’s not to say the Aurora wasn’t a great car, because it was. But it just wasn’t the sports sedan that people were looking for. There were far better sports sedans on the market and the Aurora just didn’t cut the mustard.
