DuPont's Collaborative Programs Help Replace Metal and Reduce Weight of Vehicles
Ask anyone in the automotive design or engineering community what technologies they are working on to lower emissions and improve fuel economy and half the time you'll hear "lightweighting," according to the results of a July WardsAuto survey sponsored by DuPont. Also topping the list are engine efficiency programs, vehicle electrification and adoption of diesel for engines. Sixty six percent of the nearly 900 respondents said again this year that the 2017-2025 CAFE (Corporate Average Fuel Economy Standards) could get more stringent as a result of the upcoming mid-term reviews.

"The automotive industry is racing to develop safe, fun and affordable vehicles that are much more fuel efficient a...
