By rules adopted in March 2012 by the California Air Resources Board (CARB), the 2014 BMW i3 with a REx unit qualifies as a “BEVx”, or range-extended battery-electric vehicle. It is also described as “relatively high-electric range battery-electric vehicle (BEV) to which an APU is added.”

  • The APU must not be capable of switching on until the battery charge has been depleted;
  • The vehicle must meet “super ultra low emission vehicle” (SULEV) requirements; and
