Traditional metal sheet forming allows volume production of automotive body parts such as doors and roofs via a process known as deep drawing. The metal spools off a huge roll to be pressed into a corresponding mold by a three-dimensional die. High-strength steel, such as high-alloy hardenable steel or high-nickel maraging steel, is starting to take over from conventional steel though as auto makers look to reduce vehicle weight and boost fuel economy without compromising safety or performance.

After dedicating the last several years to the pursuit of power and handling, we're finally putting forth an effort to slow down our car. Consider this to be an indicaton of hard-earned maturity (as opposed to our receding hairlines, which are just signs of getting old).
Alternative-fuel engines of different sorts all suffer from one major drawback or another: poor range, hard-to-find filling stations, high cost, poor performance. EEStore is out to change all that with a revolutionary new kind of "battery". We put "battery" in quotation marks because the unit doesn't store power in a chemical capsule like a conventional battery, but instead uses some kind of glass- and aluminum-coated ceramics. The inventors are understandably tight
