DuPont has announced a new type of resin that can work as a metal substitute. The new Zytel(R) nylon resin has replaced steel in exhaust system parts on all Volkswagen vehicles built on the current Golf platform, cutting weight of the component by nearly 50 percent. The resin is used in the catalytic converter bracket to substitute a previous multi-assembled metal and rubber part, so the benefits are not only from the reduced weight but also in the ease of assembly. As stated in the press release (which you can find after the jump), this might be a small step, but it's one small way to achieve higher mileage figures.
