Maintains the roll radius. The patented external roll hoop keeps the vehicle's center of gravity on the major radius, allowing the body to roll smoothly instead of collapsing on the trailing corner.

Minimizes intrusion. Keeps roof intrusion and speed low at the A and B pillars — protecting the occupant survival space.
