The goal here is high-speed travel over rough and uneven terrain, and Pratt & Miller's METS system is awesome to watch in action. It uses standard 20-inch rims, mounted to a dual suspension system. A short-travel suspension system gives six inches (15 cm) of regular off-road bump handling, but when the road gets really rough, an active high-travel suspension gives each wheel a whopping six feet (1.8 m) of travel – 42 in (107 cm) upward and 30 in (76 cm) downward from the center point. In this way, the METS can get around while keeping the cabin upright in some pretty extreme situations.
