1. Cylinder Cut-Off
During the ’80s when the gas crisis was happening, many automakers including GM decided to start experimenting with cylinder deactivation. This was still a new technology, so most computers were not advanced enough, which caused a lot of frustration. The technology was especially bad for Cadillac because the Fleetwood in the repair shop more than it was on the road. The same thing happened during the 2000s when GM and Chrysler begin to experiment with the technology again. However, the fuel economy was not better. Cylinder cut-off caused was a lot of headaches for those mechanics who were unfamiliar with the technology.
The cylinder deactivation of the past couple of decades was a useless attempt to increase fuel economy. It’s just not something that works on a vehicle that weighs quite a few tons and has a powerful V8 motor.
These are 25 useless car features automakers got away with for decades. If you’ve ever had to deal with any of them, you’re probably glad they are long gone. Some were useful at the time, but became obsolete with emerging technologies, while others were just plain bad from the get-go.
