2: Cylinder Deactivation
throughout the ’80s, automakers were experimenting with all kinds of new fuel management technologies. The Cylinder Deactivation was among one of the most controversial. On most of the cars that featured this technology the reliability suffered. As such, most automakers ended up moving away from Cylinder Deactivation not long after it was introduced.
Cylinder deactivation has returned in some sense of the word almost 30 years later. Most modern engines have some type of deactivation, especially on pickup trucks. It’s questionable how much fuel the technology saves. Most consumers went to have a reliable vehicle and with cylinder deactivation, this isn’t always the case.
