By 2025, every automaker will need to boost its corporate average fuel economy (CAFE) to 54.5mpg. That's not an easy task, so most manufacturers are already working with suppliers on products to help squeeze the most out of every gallon of gas. The obvious way to do that is to use electrified powertrains. But not all vehicles can do that, so automakers are building new engines, and vendors are dreaming up fuel-stingy components.
From fuel injectors and air conditioning compressors to tires and power steering systems, we offer a potpourri of technologies aimed at boosting CAFE to 54.5mpg.

Wow, Chuck. I am duly impressed. I didn't realize there was such a wide swath of technology and innovations underway to address the 54.5 CAFE standard mandate. As you well noted, the focus tends to be on powertrain technology, yet there are many other places, many probably not considered, where auto OEMs can squeeze more mileage out of their designs. I particularly was impressed by the so-called "little things"--the improvements to making the wiring systems lighter and the flaps on the Chevy Cruze for aerodynamics. Very, very interesting stuff.
For industrial control applications, or even a simple assembly line, that machine can go almost 24/7 without a break. But what happens when the task is a little more complex? That’s where the “smart” machine would come in. The smart machine is one that has some simple (or complex in some cases) processing capability to be able to adapt to changing conditions. Such machines are suited for a host of applications, including automotive, aerospace, defense, medical, computers and electronics, telecommunications, consumer goods, and so on. This discussion will examine what’s possible with smart machines, and what tradeoffs need to be made to implement such a solution.
