How much more expensive is petrol compared to a Tesla battery?  

Thanks to Tesla's battery advancements, electric cars have become competitively priced with gasoline vehicles.

Tesla's batteries are built to last and require less maintenance.  

Tesla batteries benefit from federal and state tax credits that reduce the cost of the vehicle,

regardless of how much gas prices may or may not change.

When comparing the total cost of ownership throughout the life of an electric vehicle to that of a gasoline-powered vehicle,  

the savings on Tesla batteries and tax incentives can be substantial.  

Electric vehicles powered by Tesla batteries may have a lower lifetime cost of ownership than conventional gasoline-powered vehicles.
