With a range of around 100 miles, expect to see the eStar in cities like San Francisco.  Navistar has an eStar First Responder Guide availible, so make sure you read through it.

A few key pieces of info:

  • The power steering and cab heater are both High Voltage.
  • The 12 volt battery is located forward and slightly above the right rear (passenger side) wheel well and is accessed through a removable cover on the top of the right rear wheel housing on the inside of the vehicle.  The cover is fastened and sealed requiring tools to remove.
  • All high voltage cables are covered with orange conduit or orange tape for the length of the wire.
  • An inertia switch is located in the cab to isolate high voltage in the event of a heavy impact.
  • An isolation check in the high voltage system disconnects the battery cassette in the event of a short to ground.
