|Includes:Clean Energy Fuels Corp. (CLNE), F, WPRT

BAF Technologies is a wholly owned subsidiary of CLNE. They are involved in CNG engines on the following platforms, some of which are Ford. Ford formed a partnership with WPRT as well that put fully integrated systems into light duty Ford 250s and 350s under the Westport Wing name. Ram CNG engines are designed completely in house. GM and Westport have a joint agreement for developing a CNG engine, but GM is also creating its own in house. There are some private companies in this business as well. A nice summary of CNG engines is here. Ford F-450s and 550s will be available this year with Westport's WING natural gas dual-fuel systems as of April 2013.
