GM Silverada Beats F250 In Frame Twist Test

Built in frame flex will prevent fatigue, leading to a frame that is more durable.

Care to expand on this thought process?

Built CHEVY !! TOUGH !!!!!

Well the twisting to the point of impacting door opening/closing won't impact most people, on road or off, but the flexible frame most certainly does matter to "pavement folks" in terms of ride and handling characteristics and cowl shake.

So... why does the "Test" only show unequal body lines and tailgates that won't open in extreme and absurd conditions? Furthermore, what fatal mechanical flaw did this test reveal about the F250?

I doubt the "test" showed any of that. Again, these types of demonstrations only serve one real purpose... and that is to confuse and befuddle the idiots.

I don't think this showed any fatal flaw at all - other than the potential to make the radiators leak as proven in the other video I linked. Did you watch it? It's pretty apparent that extreme flex is an issue. That said, there are plenty of satisfied F250 owners out there. It does show that the Ford Superduty frame is more flexible than Chevys.

APPARENTLY FORD THINKS IT'S IMPORTANT TO HAVE A STIFF FRAME

If you ask anyone who knows anything about engineering, they will tell you that it is more difficult to tune suspension when the frame isn't "stiff". Commercial trucks aren't concerned much with it as they have air ride cabs and driver's seats.

Are you referring to a different video or test. There was no reported damage unless I missed it.

Only at the extreme end of that bell curve would have this type of issue
on a 'regular' basis

Question is how often does a pavement queen get into this condition
out on a parking lot...launching a boat...etc ?

Then, is this a one time thing where it would damage like that Ford?

It illustrates that the ford has a flexible frame. I don't think that's going to create many practical problems opening doors or tailgates out in the real world, but it sure as heck has some big implications in the ride and handling department, as well as how solid the truck feels traveling over uneven terrain. I'm sure Ford will update the frame on the 2016s, but the current super duty frame is definitely no longer competitive with the heavy duty GM or Ram trucks.

WHY THIS TEST MATTERS

There's not really a problem with a frame that is able to flex, but the rest of the truck has to be engineered with this in mind.
