FLT gives F150 Diesel worlds toughest towing test

Just wanted to share his video that gives the F150 diesel, a serious hauling test. Interestingly enough the truck actually throws an engine code and inevitably ends up in limp home mode. It looks like they heard back from Ford and identified that this pre production model had issues with calibration. Ford has indicate this problem will not be evident on full release..hmm

This isn't a problem limited to this pre-production model because I've seen complaints from other F-150 owners before though not with a diesel engine. Let's hope Ford has ironed out this problem in all of the newer F-150 models because it's dangerous for your pickup to quit on you while driving, worse if it's on an interstate.
Well this is a pretty strenuous test, so there's a good chance you wouldn't come across this fault with regular use anyways. But yeah its going to be pretty disappointing if all this wait for a diesel engine on the F150 ends up resulting in widespread issues with the new powertrain.
i have watched that video several times, I think that they just held the engine at or near the red line for way too long. So then the engine went to self preservation mode. I would rather have that instead of a blown engine due to over revving, witch would probably not be covered under warranty. I also think this engine would benefit from either an engine or exhaust brake to help with down hill control.

I am not impressed with FLT testing, one of these days they will throw a rod thru the block of one of these test vehicles at redline rpms, no one should have to ever exceed 4500 rpms at most while towing, the other nonsense I see is taking away points by hitting the brakes on downhill, why not just manually downshift to a proper gear for the given incline? I do it all the time while towing my travel trailer, much better control anyway downshifting. I feel sorry for whoever buys these test vehicles after they are done torturing them. They may suffer premature engine failure eventually due to the extreme rpms they were subjected to.

Widespread issues? Only real issue I head of is the EGR and those will all be cleared up soon.
Poor Truck. If you drive any truck like this you will destroy it. It's completely out of its capacity.

This video is useful. It gives us bench marks and shows the limitations. However it is not real world test other than the fact that they preformed the test on a public road.

Downhill test

I wish Ford had put an exhaust brake on this truck. If they did, this test would have been radically different. Hopefully, an aftermarket will be able to do the job for the people who need it.

The engine brake was overwhelmed. I wonder how long they had the engine at redline before all the editing of the video. In my opinion they should be thanking Ford for putting in engine preservation commands. They needed to use the brake A LOT more to keep the engine RPMs down. Good thing for disk brakes otherwise they may have been in danger of runaway.

Uphill test

They held the throttle wide open the entire way. Who does that? But the tuck held together pretty well considering. I was happy to see that their engine temp at the end of the test was good (217) and from what I can make out on the dash, the transmission temp was good also. To me, this is by far them most important bench mark. Not speed and decibel levels.

.... Just my thoughts
