The most important thing of a bulletproof car is of course its ballistic performance, but it does not mean that the higher the ballistic performance, the better, because generally speaking, the better the ballistic performance, the heavier the car and the lower the driving performance of the car. As for the bulletproof car, the most important thing is to escape the dangerous scene as quickly as possible, not to be beaten slowly. Therefore, a balance between defense performance and weight must be made according to actual needs.
The bulletproof car requires not only the body to be bulletproof, but the window glass must also be bulletproof glass. It is generally composed of multi-layer glass, polycarbonate, polyurethane, etc., with a thickness of 1/2 inch of Class II and Class IIIA. 1 inch, 1.75 inches for Class III, and 2 inches for Class IV, etc., can withstand the direct impact of bullets.
These alone are not enough, bullet-proof car tires must also have anti-ballistic properties. All tires have special inserts and a central pressure relief device so that the car can still safely drive out of the danger zone after encountering a ground explosion.
The fuel tank of a car is also the focus of protection. The fuel tank of a modern bulletproof car draws on the technology of an aircraft fuel tank and has a special rubber filler. Once it is penetrated by a bullet, the rubber will automatically expand to block the loophole. And if the fuel tank is likely to be detonated, the automatic fire suppression system will start within a few milliseconds after detecting the temperature rise, exhaust oxygen and prevent the fuel tank from catching fire and exploding.
