The Shadow Hawk uses a titanium monocoque chassis design. A monocoque design is the lightest and strongest method of construction known. Aluminum is the oldest and most widely used material and now carbon fiber composite is replacing it in most high-end race cars and aircraft. Titanium was used because of its strength, light weight, repairability, and most importantly, its ability to deform under severe impacts and remain functional unlike composites that break away to absorb impacts. The last thing a Shadow Hawk driver wants is to be several hours from civilization, have an accident and an undrivable vehicle. Military studies have shown that titanium is the best ballistic base material to composite from. The Shadow Hawk is the first and only vehicle to use a full titanium monocoque in production; ever.
