  • 2014 Chevrolet Volt

    A Michigan-based startup called Sakti3 claims it has battery chemistry that doubles the energy density of today's best lithium-ion batteries. Speaking to Scientific American, Sakti3's co-founder and CEO Ann Marie Sastry says the firm's prototype solid-state lithium cells have reached 1,143 Watt-hours per liter--a number that wouldn't just transform an electric car's range, but its cost too. Should we get excited? Yes and no. Technology like this would certainly be beneficial for electric cars. Energy density is something of a holy grail for the genre, because it increases the one aspect of...

    Will California Pioneer A World Beyond Cars This Century?

    It's almost inconceivable, the idea of a world without personally-owned automobiles.

    Tesla CEO Elon Musk's Personal Touch: Secret To His Success?

    How does a car-company CEO get to be a rock star? It helps, of course, if your company makes a five-passenger luxury sedan that outdrags a Porsche 911, uses half the energy of a Prius, and has the highest crash-safety rating ever recorded. But Elon Musk has done something else to separate himself...

    Tesla Model S Drive-Unit Replacements: How Big A Problem?

    It was a car company's worst public-relations nightmare. Edmunds.com, the widely-read automotive website, bought a Tesla Model S for long-term testing in February 2013. After nine months and 11,000 miles, the car developed an ominous grinding noise under acceleration and deceleration. Under...

  • Chevrolet Volt drivetrain teardown

    There's a childish pleasure in seeing something disassembled to its component parts, whether it's a jigsaw puzzle, Lego set or an entire car. The Chevrolet Volt is new enough that you're unlikely to see too many broken up at scrapyards right now, but crash-damaged ones still give some individuals the opportunity to explore its workings in greater detail. For d55guy, the author of the video above (via Inside EVs), it's an opportunity to strip down the Volt's T-shaped battery pack and its motor, inverter and generator. Diving into the workings of an advanced vehicle like the Volt isn't...

    While unveiling its fuel-cell vehicle last month–priced to undercut the Tesla Model S ever so slightly–Toyota's Global R&D Chief Mitsuhisa Kato offered some dismissive thoughts on battery-electric vehicles. As quoted in Automotive News, the 39-year veteran of the Toyota Motor Company said: "The cruising distance is so short for [electric cars], and the charging time is so long ...
