The challenges facing the automotive community are so significant and global that they must be attacked from multiple angles simultaneously, tapping into global teams for support and fresh ideas.
Troy, Mich. (PRWEB) August 07, 2013
With automotive regulations governing fuel economy and CO2 emissions being discussed in Europe and the United States, nearly half of automotive engineers predict those regulations will strengthen, according to a WardsAuto and DuPont survey conducted in late July. Only 8 percent predict regulations will relax, primarily due to economic and cost issues, and one-fourth expect no change, the results show. (See chart "Automotive Engineers Predict Regulation Review Will Strengthen Fuel Economy, CO2 Emission Regulations")
The survey results also show the value for lightweighting vehicles to help meet targets is increasing, and that every system in the vehicle is a candidate for reduced mass. (See chart "Automotive Lightweighting Continues to Grow in Value")
“Fuel and emission standards throughout the world are driving significant changes in vehicle design,” said DuPont Performance Polymers President Diane H. Gulyas. “There are multiple solutions simultaneously getting into the market and the industry must continue to work in harmony to develop low emission, fuel-efficient vehicles that consumers want to drive.”
Now in its third year, the annual survey with WardsAuto was conducted as the European Union delayed a vote to adopt stringent 2020 emission regulations. This uncertainty, coupled with the mid-term evaluation process built into the 2017-2025 U.S. regulations, stimulated a survey asking subscribers to weigh in on the outcome and whether their companies are reacting to uncertainties. More than 1,300 subscribers to leading industry publication WardsAuto responded to the survey (see PDF file "WardsAuto World Industry Study Report (2013)"). Forty three percent say there are no changes, 36 percent say there are some or many changes in the development pipeline (see chart "Regulation Reviews Have Impacted Some Current Vehicle Programs").
While last year’s respondents gave aluminum a slight edge over plastics and composites as the material that can best help them meet regulations, respondents today are looking at all materials in the portfolio (see chart "Automotive Engineers See All Materials Helping Meet Fuel Economy Requirements").
In 2011 surveys with the Society of Automotive Engineers and WardsAuto, the automotive engineering community revealed that materials are critical to a product’s success, yet most said they were not confident that today’s materials portfolio would help them meet CAFE regulations.
“We’ve seen a variety of materials-based solutions introduced in the past couple years,” said Mike Day, DuPont Automotive Performance Polymers development director in North America. “And development activity with the automakers is intensifying, especially related to new composite and multi-material solutions that deliver the strength and stiffness needed for performance and safety.”
Last month DuPont highlighted a developmental composite technology called DuPont™ Vizilon® in a PSA Peugeot Citroen side-impact door beam. This developmental thermoplastic composite technology showed a 40 percent weight reduction compared to ultra-high strength (UHHS) steel and absorbed more energy than metal and short glass-fibre polymer beams to pass the PSA Peugeot Citroën’s crash test.
“Speed is critical,” said Day “but not at the expense of performance and safety. We believe that close collaboration on these new technologies is more important than ever before. Each of us brings to the table a deep knowledge and different perspective. The synergy experienced when we converge is the catalyst that sparks the breakthrough.”
Diverse Technologies Fuel Automotive Efforts
Lightweighting is core to meeting new standards and one that is growing in value, according to more than 60 percent of respondents. Further, when asked which systems are the most likely targets – all ranked relatively equally. “The results reflect that every system, every component throughout the vehicle is a candidate for weight savings,” said Day. “This is a great time to incorporate plastics early in the design stage since there are many more opportunities to integrate functions for significant mass and cost savings.”
In addition to lightweighting, the industry continues to optimize the internal-combustion engine, develop hybrid and electric vehicles and adopt alternative fuels. For its part, DuPont offers advanced materials to help reduce mass and improve efficiency; battery chemistries and materials for more efficient electric-powered vehicles; and has collaborated to develop low global warming potential refrigerants for vehicles and biofuels manufactured from non-food based cellulosic resources.
“The challenges facing the automotive community are so significant and global that they must be attacked from multiple angles simultaneously, tapping into global teams for support and fresh ideas,” Gulyas added.
About the Survey
The WardsAuto survey was sponsored by DuPont and conducted by Paramount Research, Coralville, Iowa. Forty-three percent of the 1,300 respondents indicate they work for system, component or parts manufacturers; 24 percent work for an automaker; and the balance work for engine or engine-service companies. Nearly half the respondents say they work in engineering, R&D or in quality/reliability. Sixteen percent work in management and the remainder represent manufacturing, purchasing or other field.
DuPont offers more than 100 materials and product families for the global automotive industry. Through its global application development network, DuPont Automotive is committed to collaborating with customers throughout the value chain to develop new products, materials, components and systems that help reduce dependence on fossil fuels and protect people and the environment.
