I saw that as well. I got the impression they were just testing the ecoboost engine. Cool video though.
False. 2015 Ford F-150 Baja 1000 Prototype - 2014 NAIAS in Detroit - Road & Track
In the most recent Baja 1000, Greg Foutz (big surprise) ran a disguised 2015 F-150 wearing aluminum body panels stamped out in the 2009-2014 body styles. Pretty sneaky. They did, however, say it was kept as stock as possible. I'm guessing this was not a Raptor mule as it would at least have to be wider and with all the good publicity I doubt they want to disguise the Raptor during its Baja debut.
