What good is a truck if it can't be used to invade your neighbors? Not much good. Not much good at all, say the armament experts at Rheinmetall Defense.At the recent Eurosatory defense expo in Paris – consider it the Geneva Motor Show of military hardware – Rheinmetall unveiled its conversion options for the Volkswagen Amarok , transforming the four-door short-bed civilian pickup truck into a Light Multi-Purpose Vehicle for military applications.The options list includes a reinforced suspension, advanced communications systems and an automated, motorized turret for a machine gun or grenade launcher. (The actual firearms are another, matter, of course.) Military and paramilitary buyers can order theirs with a variety of engines ranging up to 177 horsepower, with either six-speed manual or eight-speed automatic transmissions.Somehow, we're guessing that even if this Volkswagen does show up in Canada as is being discussed , we don't see our neighbors to the north getting these sorts of optional extras.
