Did you guys watch the other videos in the series?
That motor has over 150,000 simulated miles (weeks of 4000-6000 RPM's in a lab). Then they slapped it into a new Ford....
After the log test they towed 11,300 LBS around a Nascar track for 24 hrs (about 1600 miles) averaging 84 MPH, sometimes exceeding 90 MPH. Only stopping for fuel and tire changes and maybe a driver change.
In the next video they pit the Ford against a Chevy. Pretty amazing little motor that V6 Ecoboost is.
Oh and this is just the Ford F150. There are several videos of the new 6.7L Superduty pwning every aspect of the new Chevy and Dodges.
Oh and I see next to nothing wrong with the ball thing, that was probably a 2-5/16th ball with a 1-1/4" shank meaning if you where to hook a trailer and load up you could tow up to 10,000lbs. And that chain wasn't going anywhere guys and you know it.
