Saturn alerts customers it is considering a spinoff

Saturn has begun alerting customers that it may be spun off by General Motors as an independent marketing and distribution company. In a letter sent to about 1.5 million Saturn owners Wednesday night, Saturn said it would have to line up products to sell--either from other manufacturers or from GM in the role of a vendor--after GM's current commitment to build Saturn products ends after the 2012 model year. "The Saturn Distribution Corporation already exists as an indirect subsidiary of GM," wrote Jill Lajdziak, general manager of Saturn, in the letter.

MIT researchers rethink electric-car batteries

Researchers at the Massachusetts Institute of Technology say a new battery design for electric vehicles could be a lightweight and inexpensive alternative. The goal for the team's three-year project, launched in September 2010, is to have a functioning prototype ready to be engineered as a replacement for existing electric-car batteries. At this point in the project, the prototype uses a “semi-solid flow” to separate the two functions of a battery--storing energy and discharging it when needed--into separate physical structures.
