The DeVille Protection Series, Detroit-based Cadillac’s entry into the protected vehicle market, was designed to meet the security needs of high profile individuals requiring luxury and personal protection as they travel. The company offers two distinct models: a standard wheelbase model and an 8-inch extended wheelbase model, both of which can withstand handguns as powerful as a .44 Magnum. Significant components include an armor shell, ballistic glass, a self-sealing fuel tank and run-flat tires with an advanced bead-lock system.
