  • Prototype production of battery modules for BMW Group’s fifth-generation electric powertrain

    As automakers develop more efficient electric motors, EVs pulling electrons from dirtier, coal-powered grids are as clean or cleaner than even the most efficient fossil-fueled cars when it comes to equivalent tailpipe emissions. But electric vehicles still have a supply-chain problem. A partnership between some of the world's largest automakers is looking to fix it.

    Rare-earth metals in magnets for electric-car motors: what you need to know

    It's not surprising that the powertrains of electric cars differ quite a bit from traditional internal-combustion engines. Although they have fewer moving parts, the rare-earth magnets that help power electric cars can be quite complex to fabricate. So, what is there to know about rare-earth...

    Why Can't Other Plug-In Hybrids Copy Chevy Volt's All-Electric Running?

    The distinguishing feature of the Chevrolet Volt has always been that as long as it has charge left in its battery, it runs solely on electricity.

    Mitsubishi's Mini-Motor For Electric Cars Integrates...Well, A Lot

    Electric vehicles already offer car designers much greater freedom than internal combustion vehicles, eliminating the need to find space for the rigid shape of an engine, its transmission and its ancillaries. That's not to say electric vehicle packaging can't be improved though, and Mitsubishi is...

  • Axiflux compact electric motor (Axiflux)

    All that sitting in front of the TV watching bad sitcoms could pay off, if a new electric motor proves successful in field trials. A startup in Melbourne, Australia, has developed a new motor for use in an electric-powered Holden Commodore. There's nothing wildly special about that, but the new, more efficient design was only possible due to the popularity of plasma televisions bringing down the cost of certain electrical components. According to GoAuto, the motor, developed by David Jahshan and his company Axiflux, is claimed to be smaller, lighter and less expensive than existing designs...
