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.

Future products: The new Ford has learned to think small

Ford Motor Co., long known for pickups and SUVs, will emphasize cars, crossovers and fuel-efficient engines in the next few years. The company wants to be the fuel economy leader, and federal mpg standards are rising. Ford launched the Fiesta subcompact this summer and will introduce a redesigned Focus compact early next year.

Your official BMW i3 photo gallery

Try to contain yourselves. To help refresh your memory, the new i3 is the first road-going BMW model to be based around an all-carbon-fiber body.
