There was also another "torture test" just filmed down at Miami Holmstead.... Ecoboost F150 @ max tow rating, running at WOT for a 24-hour period. That should be ready for viewing soon, and will shut up all the haters about extended towing "burning" up these turbo engines.
Yup, what ^ said. I know first hand that a LOT of extra engineering went into making this engine (and the rest of the lineup too of course) extremely durable, and able to run tests like this 24hr endurance run without skipping a beat.
