Beth, I too am exited that these technologies are being explored and implemented.  I am not surprised, because many of these innovations are not new, certainly start-stop technology is something that is not new and could have been implemented 20-30 years ago (has been on the Prius for 15 years).  My hat is off to DN and Captain Hybrid for bringing some of the new technologies to light, we have heard too many excuses as to why we can't reach CAFE standards, and not enough examination of technology and innovation.  These are only 19 ways (there are many more existing) that can be used to increase mpg ratings, not to mention ideas that have not even been thought of yet.  Interesting that none of these ideas force cars to be smaller, and they don't even include hybrid technology.  Coupled with hybrid/electric technology, the 54mpg standard should be met easily if we stop fighting about it and start engineering.

I agree, Beth. There are a lot of little technologies that eke out a few tenths of an MPG. The technology that will have the biggest impact, and will be most widespread, I think, is start-stop. Over the next ten years, we'll be seeing that on huge numbers of vehicles.

The last time automakers needed to improve MPG, we got more aerodynamic, lightweight cars and other great technologies.  It all adds up.

The downside was the loss of individualism in design.  As things improve and become more standardized, everything starts to look alike. 

Nice slideshow.  Thanks for sharing!

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.

A pure electric car with a lithium-ion battery can lose as much as 57% of its range when the temperature dips and 33% when the mercury rises, a new AAA study says.
Volkswagen AG is developing a lithium-air battery that could triple the range of its electric cars, but industry experts believe it could be a long time before that chemistry is ready for production vehicles.
