vx has...

215 hp
230ft lb of torque
a very still suspension and zippy ride.. handles like a sports car

torque on demand is an awd system of sorts that keeps sends more torque to the front wheels when the rears start to slip, controlled by a computer under the passenger seat and (10 i think) sensors

offroad.. you cant beat a stock vx.. stock vx's with stock tires conquer moab utah every year even when driven by novice off roaders.. there arent quite as many upgrades for a vx as there are say for a jeep.. but for as little as $160 you can lift your vx 3 inches, any higher than that and there is some extensive modding involved (differential drop brackets, cutting of the cladding, heavy duty tie rods, longer brake lines etc) but its all been done... there are a few vxs with 36" tires after extensive mods.. many with 33"
