Tesla means conservation:

The Tesla Motors company announced yesterday that it will be producing a standard - everyday model that will allow for more consumers to practically own a full electric car. The vehicles will have similar range to the higher priced models and have similar teachnology but they won't contain the near 70,000 pricetag associated with the cars. 

Tesla claims that their new line of Tesla cars will be available for consumer purchase by spring of 2015.
