If you thought replacing the wheels of a Subaru WRX STi with a Mattracks rubber track system was impressive, take a look at the strap-on tank that turns your old rust-bucket into a half tank, half car, true all-terrain vehicle.

Apparently the brainchild of a resourceful inventor from Chelyabinsk, Russia, Metelica is constructed from the leftover tread assemblies. As the videos show, the car is driven onto the treads, the wheels are removed and (although exactly how the conversion works remains a bit of a mystery to us) the driver is able to control both the speed and steering of the treads using the cars controls.

Check out the vids to see the strap-on tank in action. If you can enlighten us with further details, please drop us a line in the comments. We’re sure we’re not the only ones who’d love to learn more about this unit.
