The 2012 Ford Focus, on sale early next year in North
America and Europe, uses cotton from recycled clothing for carpet backing and
"Ford is continually looking for greener alternatives," says
Carrie Majeske, product sustainability manager. "One of our key goals is to use
more recycled or renewable materials without compromising performance or
durability. Recycled content is a way to divert waste from landfills and reduce
the impact of mining virgin material."
Ford is implementing a strategy to broaden use of sustainable
materials. "One of the key goals of this strategy is to identify and globally
implement materials technologies that improve environmental and social
performance and lower costs," the company says in a report.
Two direct engineering impacts are the development of global
specifications for sustainable materials and standardization of sustainable
One big winner in Ford's new strategy will be increased use
of post-consumer recycled plastics and other materials. Ford says cars already
start with a high content of recycled materials - 20 to 25 percent - because of
the use of steel scrap in mini mills.
This year, Ford specified the use of textile materials using
30 to 40 percent recycled content for rear wheel liners. "These fabric parts
are 50 percent lighter than plastic wheel liners and absorb sound, which will
enable improved noise vibration and harshness performance while potentially
reducing the need for sound-deadening insulators, sprays and foams," Ford says
in its report.
The recycled materials resin strategy saved Ford $4 to $5
million in 2009 and diverted between 25 and 30 million lb of plastic from
landfills. Use of in-house scrap materials is not counted toward Ford's
Ford is also a leading user
of sustainable materials, such as seat foam made from soybeans.
A bold, gold, open-air coupe may not be the ticket to automotive nirvana for every consumer, but Lexus’ LF-C2 concept car certainly turned heads at the recent Los Angeles Auto Show. What’s more, it may provide a glimpse of the luxury automaker’s future.
The complexity of diesel engines means optimizing their performance requires a large amount of experimentation. Computational fluid dynamics (CFD) is a very useful and intuitive tool in this, and cold flow analysis using CFD is an ideal approach to study the flow characteristics without going into the details of chemical reactions occurring during the combustion.
