Lear has now developed a new kind of foam made from soybean oil that they're marketing as SoyFoam. It's lighter than traditional foams and less susceptible to fluctuations in oil prices. So far both the 2006 Chevrolet Impala and Ford Five Hundred are using limited amounts of SoyFoam. When combined with some of the other alternative interior materials like Honda's bio-fabric and the new recycled interior fabric that Ford is introducing on the 2008 Escape, crude oil consumption is being reduced in the production as well as the operation of new cars.
