It was my gf's dad's F150 FX4 with the 5.4l engine, her brother drove it down to this field so we could jump start a dead 4wheeler and then it got stuck. The reason it was stuck is because the F150 (along with most 4x4 trucks on the road) have all open differentials. If one wheel spins, then the truck goes nowhere, essentially making the truck 1 wheel drive. (I even took a stab at trying to get it out, but it would never move an inch, just because one wheel would keep spinning.) My point when it comes to this topic is that a 4x4 isn't really a 4x4 until it has either a locking center diff, some sort of traction control, or some sort of limited slip differential. What makes the WRX great (and 90% of WRX owner's never even notice) is the fact that the WRX comes from the factory with a limited slip center differential, and a limited slip rear. This essentially means that the front or the rear can get as much power as it needs to keep the car moving, and the rear left or right side can individually get power it needs to keep the car moving. It's not just the F150 that has all open difs, it is Dodge, GM, and all kinds of other trucks. I mean some do have decent drivetrains, but most don't. The WRX won't win any rock crawling events, but it will definitely be stronger in grass, snow, mud, etc. than 99% of trucks on the road today. That's definitely something to consider when people actually are somehow trying to compare it to a Chevy Cobalt. It's in a whole other league. It's like comparing apples to um . . . . steak.
