Actually no. I noticed this last month when they changed to the 2014 models. I emailed Mark Williams at Pickuptrucks.com about this since he published different numbers on premium fuel. His response is below.
This is just how Ford published that the 2011 Ecoboost had a different 6th gear ratio then all the other engines in the spec sheets, but it actually didn't. It wasn't fixed until the following year. I have yet to email Mike Levine who used to have Mark Williams' job as chief editor at Pickuptrcks.com, and now is Ford's truck communications manager. I will let you guys know what he says as well.
