If you want to show up anyone with an older 4x4, just get them crossed up with opposing wheels off the ground. The Yeti with it's traction control will apply the brakes to the wheels off the ground which will then make the wheels that are on the ground drive. I don't know how technically minded or your knowledge of diffs but that's simply how it works.
I had a mate follow me in his 100 series Land Cruiser. There was this very steep track that ended sharply and on and angle. There was no room at the bottom for a run up due to a sharp bend so it was drive slowly up this steep pinch and then the front left wheel came off the ground until the car passed balancing point, the front went down and the opposing rear came up. The Yeti just podded up nice and slow and smooth at the rocking point there is no weight on 1 front and 1 rear wheel so both of these wheels have no traction. With a normal vehicle, you would just be stuck but as I said before the Yeti applies the brakes to these wheel and you continue on. My mate was very worried that he'd never live it down if he didn't make it. He did but it looked ugly as he tried to get enough speed up this steep pinch so he could get over the rocking point with momentum.
Happy Days.
