Light-duty vehicles cost $5,000 to $10,000 more than their gasoline-powered counterparts. Those “incremental” costs can be offset by State and Federal incentives and by the fuel savings.
Other light and medium-duty vehicle conversions can cost $10,000 to $15,000. Several states also offer additional incentives such as rebates or tax credits. Check with your local area to see what incentives are available. The District does offer CNG vehicle rebates for individuals and will consider project incentives for other fleets considering CNG vehicles on a case by case basis.
