I finally had a chance to catch up on some of these new comparison videos this morning. This one was is pretty interesting considering the vehicles are close in price ($5000 difference). I was surprised the articulation was the same as a Bronco Sasquatch. Not sure why?
I have a couple thoughts on the articulation subject.
1. this test as with others I have viewed, does Not account for ground clearance which would add to the vehicles off-road rock crawling capabilities.
2. this test doesn't account for wheel base differences.
3. The Bronco Raptor being dual purpose has greater progressive rate springs and shocks to where the vehicle weight alone will not compress the springs to full travel, this plays part in comparing to the Rubicon and Sasquatch Bronco.
I suspect the Rubicon in this test is near or at full suspension travel.
The F-150 Raptor, the progressive rate springs in front may be even greater than the BR to accommodate a greater weight over the front axle, and the rear springs must be of higher capacity (stiffer) to accommodate truck bed loads and higher trailer tongue weight with the increased trailer towing (almost double the BR).
Summary, the Jeep and Sasquatch Bronco are designed primarily as rock crawlers where as the BR is dual purpose as rock crawler and high speed off-road (launches with soft landings) and the F150 Raptor is also dual purpose with high speed off road (launches with soft landings) and will tow and carry twice the load of the others.
This is my explanation for this video's articulation results Not being what I expected.
