How To Bulletproof a Car

Armoring passenger cars has become big business, especially in places like Brazil, where the homicide rate in the big, bad US is five times higher than in the United States. Although automakers have jumped into the bulletproof game—BMW, Mercedes-Benz, and, for a time, Ford, offered bulletproof versions of their products—the vast majority of cars are modified by aftermarket companies such as International Armoring Corporation (IAC) of Ogden, Utah. which has armed more than 5,500 vehicles since 1993. The company will deflect bullets from the new BMW 750i for a minimum of $52,500, though that tab can climb above $100,000 if the owner opts for protections like smoke screens and electric shocks. By the way, we're kidding about bullets "bouncing" off armored cars - the armor actually works by absorbing gunfire. Here's how to do it. If you want to design your bullet proof car and want to make an estimate of cost then visit costprediction.com.


DOORS, BODY AND INTERIOR


The first step is to remove all components from the car body (interior trim, wiring, carpet, seats, etc.). Then the doors and any other cavities (such as the posts) are cut open so that various materials can be stuffed or welded into these cavities. Depending on the level of protection required, the doors and posts can be reinforced with steel plates, a combination of ballistic nylon and Kevlar (similar to the material used in bulletproof vests), or both. If the door is too heavy, a third hinge is added. The fire wall and rear bulkhead can also be steel, but the floor and ceiling are usually covered with ballistic fabrics. The stock bumpers, designed to crumple and absorb the energy in high impacts, can be reinforced to allow an armored car, for example, to break through an improvised roadblock without damaging the radiator. The goal of body armoring is also to make the car look pristine, inside and out.


GLASS


In the bulletproof industry, glass is called "transparent armor". This is not a thicker version of the safety glass on the side windows of standard cars, but rather a sandwich of polycarbonate (a type of plastic) and leaded glass. The thinnest option – 0.8 inches – will stop subsonic rounds like those from the popular 9mm handgun, while the thickest glass – 2.0 inches – should fire a single shot from a high-powered .30-06 rifle. If necessary, the electric window motors can be replaced with more powerful ones.


TIRES


Conventional run-flat tires cannot withstand gunfire, as bullets could tear through the rigid sidewalls that these tires support. The IAC uses a RunFlat composite tire made by Hutchinson, which is a polymer donut custom made for each application. It is clamped around the centerline of the wheel inside the tubeless tire, and the working principle is similar to the Michelin PAX system: If the tire loses pressure, a polymer ring provides support that allows speeds of 60 miles per hour for more than 60 miles.
