I'm personally not an SUV fan, I'd take a touring anyday. And while 400hp or whatever out of a 6.1L isn't all that impressive by todays standards, it's not all about horsepower all the time. While in a perfect world a naturally aspirated 6.1L engine should have at least 610hp and 610ft-lbs, that will never happen. From what I've seen, it's a trade off, you can get 100hp/L, but the torque will be lacking, or you can have a lot of torque, but the rpm's and the hp won't be there. For the purpose of an SUV, torque is the direction you'd want to go.
Also, having a huge vehicle like this (with a solid rear axle I belive) still do 0.9G's on a skidpad, that's pretty good. And they're doing something BMW's seem to avoid, 4-piston brake calipers. 125ft to stop from 60mph is great for a small car, let alone from an SUV.
At that price, you can probably out perform any new BMW or Mercedes.
"Driving is like a narcotic, an addiction that can take over lives. It ruins people, breaks families apart, and even kills. Itís habit that needs to be fueled. Time, money, rationality, sweat, knuckle skin, and anyone who disapproves are of little importance to a driver, and are often overlooked. Hi, Iím Nelson, and Iím a drivaholic."
