XP1K

If you've well been sleeping on UTVUnderground's XP1K side-by-side series, then you're one of the few, with the truly batshit off-road video series racking up over 16 million views across its first two installments (which you should definitely check out if you haven't already). Riding that incredible viral crest, the SxS auteurs dropped their third epic, XP1K3, yesterday and, much like its predecessors, the results have to be seen to be believed. Featuring RJ Anderson pushing a 200-hp Franken-Polaris RZR XP Turbo to its absolute gravitational limits amongst the burnt-out factories and rusted-through trainyards of Youngstown, Ohio, this one might well be the craziest driving video of 2015, so strap in, fire it up, and put that right foot to the floor.
