This video explores the effectiveness of a standard car as ballistic cover, testing various firearm calibers against a Mazda 626. The experiment reveals that while handgun rounds and even 5.56 can penetrate doors and windshields, the engine block offers the most reliable protection. The host, an enthusiast with practical testing experience, demonstrates safe firearm handling throughout the process.

Quick Summary

Testing reveals that standard car doors offer limited ballistic protection, with 9mm FMJ rounds penetrating both front doors. While smaller calibers may be stopped, higher calibers will easily breach panels. The engine block is the most reliable component for stopping bullets, including .50 caliber rounds, making it the only truly bullet-resistant part of a typical vehicle.

Frequently Asked Questions

Can a car door stop bullets?

Standard car doors offer limited protection. While smaller calibers like .22 LR and .380 ACP may be stopped, 9mm FMJ rounds have been shown to penetrate both front doors of a typical sedan. Higher caliber rounds will easily defeat door armor.

What part of a car is bulletproof?

The engine block is the most reliable component on a car for stopping bullets. In testing, even a .50 caliber round was successfully stopped by the engine block, proving its significant ballistic resistance compared to body panels or glass.

Will a 9mm go through a car windshield?

Yes, a 9mm round will penetrate a standard car windshield. Testing shows that 9mm FMJ rounds, along with .22 LR and 5.56 NATO, can easily pass through the glass, posing a significant risk to occupants.

Is a car a good place to hide from gunfire?

While a car might offer some minimal cover, it is not reliable ballistic protection. Doors and windows are easily penetrated by most common firearm rounds. The engine block offers the best protection, but it's not practical to use as cover during a shooting scenario.
