Can You Explode a Car by Shooting Its Gas Tank?

It seems counterintuitive. You’d think punching a hole in a fuel tank would be a one-way ticket to the afterlife. Car makers reinforce the entire fuel system for a reason. Manufacturers know that a hard enough impact to rupture a gas tank usually kills everyone inside or near the vehicle. The National Highway Traffic Safety Administration (NHTSA) enforces strict regulations to prevent this. They run side-impact and rear-impact tests on every new model. The goal is simple. Keep damage below acceptable limits. The agency then publishes safety ratings for the public. They also standardize non-gasoline systems. Hydrogen tanks, compressed natural gas lines, and electric vehicle batteries all fall under these same rigorous scrutiny.

But cars fail these tests sometimes. That implies fuel tanks might not be protected as well as we assume. Plus, getting T-boned isn’t the same as getting shot at. A bullet travels differently than a crumpling steel door. It moves faster. It carries heat from friction. What happens when the impact source is an extremely fast projectile rather than blunt force?

TV shows and movies love to tell us that penetrating the rear of a sedan triggers an instant explosion. Filmmakers often cut corners. But the premise is somewhat plausible. Gasoline is highly flammable. That’s why it powers your engine. Firing hot bullets into the tank could theoretically replicate the detonation process of an internal combustion event. That’s why the idea sticks in our heads.

To test this, Discovery Channel’s MythBusters took matters into their own hands. They aimed a Cadillac sedan with several rounds. All shots targeted the fuel tank directly. The result? Nothing. No fire. No explosion. The six bullets passed through one side and exited the other. Zero drama. No one has stepped up to replicate this specific experiment since. At least, none that are publicly known. So, MythBusters provides the most compelling visual evidence we have. We aren’t saying it’s completely impossible to blow up a car by shooting its gas tank. We’re just saying there’s no evidence it’s ever actually happened.
