Unibody construction forms a rigid, cage-like safety cell around the occupants. The body and chassis are welded into a single shell with reinforced pillars, floor, and roof that resist crash intrusion and keep the cabin intact. Energy from a impact is absorbed by designed crumple zones and load paths that steer forces along the vehicle’s structure, protecting occupants by maintaining a stable interior space. This differs from a ladder-frame design, which uses a separate frame and can allow more cabin deformation. Subframes and engine cradles are parts of the overall structure, not the primary safety cell itself.
