Survey: Battery, Engine, Materials Are Top CAFE Techs
9/19/2012

A DuPont-sponsored survey has found that automakers are focused almost equally on improving battery performance, breakthroughs in combustion engine performance, and lighter materials.   (Source: DuPont)

I agree, Chuck. weak sales of EVs make EVs a weak contributor to CAFE standards. Of course that could change quickly if battery technology breakthroughs bring down the cost of EVs and hybrids. What do you think the chances of that are?

I agree, Rob. EVs have the potential to help boost CAFE, but first, someone's going to have to sell them. Nissan Leaf's recent sales numbers have been unimpressive.

I agree, Mydesign. Until there is a significant breakgrough, the EVs will probably not contribute greatly to meeting CAFE standards. As it stands now, the EVs will proably not have sufficient sales to help car makers meet CAFE.

Lou and Matt, I suspect aerodynamics issues run smack into fashion and style issues, and what the car companies think people want in terms of appearance.

I asked Carole, the DuPont spokeswoman quoted in the article, if we could give more details. Carole, thanks for sharing these with our audience and addressing their questions about DuPont's survey design and the survey respondents.

Thinking_J, the pie chart represents categories summing up this section of the results of the survey, which included many questions posed to respondents. There are also other illustrations depicting somewhat different data from the survey, which you can access using the link we provided.

Want to share some info Ann didn't have room to include.  Respondents were asked to report on the types of programs they are working on – not what they believe.  As most folks probably know, the industry is currently working on programs designed to meet milestones along the way to 2025 regulations.

Also, the makeup of the survey represents several points of view:  half report they are in the system/component  segment of the value chain; 31% are in the OEM role; and 17% say they work in engine/engine services.  Half are in the engineering role, with the rest spread between quality; corporate management; production engineering; and research & development.

Rob, in case of EVs the main two major areas which are lagging is Battery power and engine power: which are related to each other. So any further improvement has to happen in these two areas, otherwise it cannot improve efficiency. Putting up more charging stations is not an issue, but better yield from battery is an important factor.

Light strong materials not new.

Some time ago I helped restore some automobiles fron the 1920s.  I was surprised at the range of materials the manufacturers used to provide light strong structures.  These included not just steel, but hard and soft woods, aluminum, fabrics, and such plastics as existed then.  During the decades that followed, the US manufacturers slid a long way backwards in the materials department.   It's good to see that they are again gaining ground.

The graph represented what the 700 subscribers to WardsAuto "thought" as they were polled...  not much more meaning than an "exit poll" at an election. It did not indicate where the automotive decision makers were actually spending their research dollars. It did not indicate relative value of improvement vs money spent in any scientific way.. it was the "gut" feeling by subscribers to a "automovtive information center" on the subject.

So .. at best we have some indication from a few in interested in the industry where they believe improvements are to be made.

Sorry Ann, I want a bit more "meat" to the subject before making any meaningful observations.

As the 3D printing and overall additive manufacturing ecosystem grows, standards and guidelines from standards bodies and government organizations are increasing. Multiple players with multiple needs are also driving the role of 3DP and AM as enabling technologies for distributed manufacturing.
A growing though not-so-obvious role for 3D printing, 4D printing, and overall additive manufacturing is their use in fabricating new materials and enabling new or improved manufacturing and assembly processes. Individual engineers, OEMs, university labs, and others are reinventing the technology to suit their own needs.
For vehicles to meet the 2025 Corporate Average Fuel Economy (CAFE) standards, three things must happen: customers must look beyond the data sheet and engage materials supplier earlier, and new integrated multi-materials are needed to make step-change improvements.
3D printing, 4D printing, and various types of additive manufacturing (AM) will get even bigger in 2015. We're not talking about consumer use, which gets most of the attention, but processes and technologies that will affect how design engineers design products and how manufacturing engineers make them. For now, the biggest industries are still aerospace and medical, while automotive and architecture continue to grow.
More and more -- that's what we'll see from plastics and composites in 2015, more types of plastics and more ways they can be used. Two of the fastest-growing uses will be automotive parts, plus medical implants and devices. New types of plastics will include biodegradable materials, plastics that can be easily recycled, and some that do both.
