I was just checking the car listing in www.fueleconomy.gov and found curious listings for:All three are listing some "F150" vehicle. Note, apparently these are remanufactured vehicles using propane or other alternate fuel systems.

There are some other manufactures I don't remember before:You find the cars listed have no photos. The changes were so great that at first I thought someone has hacked their site. Instead, they've expanded to include some alternative fuel vehicles. They now have a downloadable PDF file and these new vehicles were listed in the PDF too. That is more than a simple hacker attack.
