Military-inspired and military grade, Polaris TerrainArmor is one badboy piece of kit. Sporting specially made non-pneumatic tires, this all-terrain beast of a vehicle will tear up any track your dare take it to. Boasting an incredible center of gravity, its 77-hp engine will launch you across any surface, and it's so tough it can take a hit from a 50-cal round. But we don't recommend it.
