Uber made a deal with Green Wheels and Chinese automaker BYD to use BYD's e6 electric cars. Uber's first fleet of twenty-five electric vehicles is being tested in Chicago. Uber hopes to expand its Chicago test market to include other cities and add hundreds of BYD electric cars to its fleet before the end of the year. If you're unfamiliar with China's BYD, or "Build Your Dream," you're not alone. In America, when we think of electric vehicles we may think of the Tesla or Nissan Leaf instead of BYD.
