Automakers spend billions of dollars on research and development in the never-ending quest to make internal combustion engines (ICEs) more useful and efficient. Sometimes that spending results in a giant breakthrough, like the electric self-starter developed more than 100 years ago. But most often, it results in small but significant gains, which is the case with BMW’s eBoost.
Those who follow automotive technology grasp that “e” most often refers to some form of electrification. At the same time, “boost” typically refers to something that momentarily increases performance. For instance, that is the case with the “boost” gained from turbocharging or supercharging. Based on this background, it is not surprising that BMW eBoost refers to a method of improving vehicle performance by adding a relatively short-duration “burst” of horsepower electrically.
