Cars powered by gasoline were sold for many years before hybrid vehicles that use gasoline， electricity， and solar energy．Car companies are now making cars that are fully powered by electricity only．How do these electric cars measure up to（符合标准） traditional gasoline cars？

      Electric and gasoline vehicles look similar on the outside．They have very different parts under their hoods，though． Electric cars have one main moving part：the motor．But gas cars literally have hundreds of parts，often requiring frequent maintenance（保养）．Having fewer parts makes the electric car cheaper to maintain and less likely to have mechanical problems．

     Electric vehicles are energy efficient，also making them cheaper to operate．It costs about ＄ 1.00 to travel 43 miles in an electric car，which is a clear contrast to a gas car， which costs about ＄1.25 to go 18 miles．Basically， an electric car can go twice as far as a gas car for the same price．

    Electric vehicles do not have tailpipe emissions ，making them more friendly to the environment， too．

    While some details make electric cars seem attractive， other details aren't as favorable．For example，some electric cars can travel only 60 to 120 miles on a full charge（充电）．Most gas cars can drive hundreds of miles on a full tank．

      An electric car has to stop more often to get recharged．Therefore，a gas car would be a better option（选择）if you have far to drive．And electric cars aren't as convenient（方便的） to power up as gas cars are．There are plenty of gas stations， but not many charging stations for electric cars．Then， once an electric car reaches a charging station， it can take up to six hours to charge．

    There are certainly benefits to both electric cars and gasoline cars．It’s good to know that there is an option．
