 Consumer Reports ' analysis show that many Chevrolets lose about half of their purchase price after three years of ownership , and if the Volt depreciates the same , US $ 17 @,@ 000 seems a reasonable estimate . However , Consumer Reports have noted that fuel @-@ efficient hybrids and diesel models often depreciate far less than most vehicles , which might increase the Volt 's resale value after three years above the US $ 17 @,@ 000 estimate . Additionally , if gasoline prices continue to rise or if the tax credits expire , the demand for used Chevrolet Volts could quickly increase , raising their market value . On the other hand , if the next @-@ generation Volt ’ s battery has twice the capacity and cost less , as General Motors has claimed , the first generation Volts will be obsolete when the new ones come out in 2015 . Considering these assumptions , Consumer Reports considers that " at this point we believe it ’ s still unclear how the Volt will fare . "
