It’s just a few weeks since we learned that Daimler and BYD had come up with a name for their joint venture in China to produce New Energy Vehicles (basically EVs). Denza – or Tengshi, in Chinese – seeks to take Daimler’s expertise in car making (and they do claim more than any other car maker on the planet) and mate it with BYD’s undoubted expertise in electric cars to build a car company that only produces new energy vehicles.
