iirc, this thing is a truncated 4WD 4Runner platform. At least that's how it was originally designed. A small SUV to compete with the Element and draw niche ownership by marketing towards a "younger people, outdoors-ish" demographic.
Should be a 5VZFE under the hood unless they went to the 4.0 V6... which is a ... 1GRFE according to my fast-moving parts books. Never saw any regular warranty claims or damages to that engine that I can remember (spent 3 years in a parts department). Only thing funny about it was using a different style oil filter.
It's a good trial-sized SUV. I like it. I'm biased though. I love my 4Runner, and anything on a Toyota PreRunner platform is usually rock solid.
Only thing I don't like, which they do to all production cars... is they completely screwed up the interior. The concept interior was much nicer looking. Also can't tell from the pic.. but it looks like they replaced the solid rubber floor with carpet. Kinda ruins the point of it imho. Get it dirty, clean it with a hose, drive home.
