i have to agree with toto, i cant say the v8 is the better engine, yes, both are great, i have the v6 in my 08 highlander, but i will say, ive owned 4x4s since 73, most had 4 or 6 cyl., one had a v8. all had selectable transfer cases, except one also had the fulltime option.(grand cherokee). so i went shopping for a v6,selectable transfer case, t4r,... drove both engines, & was just greatly impressed with the v8, it seemed smoother & quieter. not only was i surprised, but i was also greatly impressed with toyotas version of fulltime 4wd. to me, it seems better than alot of other auto makers versions. so, even tho i wasnt looking for the v8 with FT4WD, i ended up buying one, & can honestly say i dont feel " saddled" with anything. its also nice to have a v8 again before we all have to start driving a prius , not that theres anything wrong with that. im not trying to offend anybody, just telling my story to the person whos looking for a T4R, good luck, youll enjoy either version of this great vec.
