Survey of auto industry identifies challenges in meeting new CAFE standards

According to a WardsAuto and DuPont Automotive survey conducted in late July, if the auto industry is to meet 2025 fuel economy standards, its current materials portfolio should be augmented. Respondents also believed that there will be more changes in materials used in power train vehicle systems. More than 1,000 subscribers responded to the WardsAuto survey which was designed to identify the challenges and trade-offs associated with the 2025 U.S. corporate average fuel economy (CAFE) standards. The survey was commissioned by DuPont and was conducted before the original 2025 fleet average of 56.2 mpg (4.1 L/100 km) proposed by the Obama administration was negotiated to 54.5 mpg (4.3 L/100 km). “Clearly CAFE regulations have confronted the industry, but they’ve also driven focus around technology needs, material demands and cost issues,” said David Glasscock, DuPont global automotive technology director. He added, “While the CAFE standard is a little lower than proposed, it’s significantly higher than where we are today. Advanced materials, alternative propulsion systems and new technologies must be developed quickly and cost effectively.” Respondents also said that there is a need for higher strength, lighter metals like aluminum and magnesium among others. They also said that there should be more cost-effective advanced composites for structural components which can reduce weight significantly. High-heat resistant, lightweight materials that will withstand higher combustion pressures and temperatures are also needed. (August 3, 2011)
