New techniques cut cost of carbon fiber

Carbon fiber, once so costly that it was the preferred material only for fighter planes and supercars, is catching the attention of weight-conscious automakers. Carbon fiber's cost is falling dramatically, thanks to production advances that let suppliers speed the material's finicky, and costly, curing process. One technological breakthrough that makes carbon-fiber auto parts more affordable may come from a process used to make carbon-fiber golf clubs.

BMW delays X3's U.S. launch to push custom orders

BMW is delaying the U.S. introduction of the redesigned X3 to launch a system designed to encourage buyers to custom-order the crossover to their specifications, says Jim O'Donnell, president of BMW of North America. The delay could put the X3 in U.S.

Battery breakthrough set to accelerate electric-car development

A team of scientists working at the Massachusetts Institute of Technology are claiming a significant breakthrough in recharging times for lithium-ion batteries. According to findings published in the scientific journal Nature, MIT researchers Byoungwoo Kang and Gerbrand Ceder have unlocked the potential of lithium-ion batteries by patenting a unique process which is claimed to allow a typical laptop power pack to be fully recharged in less than a minute--an improvement in recharging performance of roughly 90 percent over existing lithium-ion batteries. Lithium-ion batteries generate electric current via the flow of lithium ions across an electrolyte, from an electrode to a cathode.
