Fire in the car: can cars explode?

First there is a fire in the engine compartment, then there is a bang and the whole vehicle is blown up - there are scenes with exploding cars in action films again and again. But: how realistic is that? And what do you have to do if the car is on fire?

Under what circumstances and how quickly does a car catch fire?

A fire can result from a short circuit in the vehicle electrical system or from a hot bearing. There is also a risk if fuel lines or the tank are damaged and the gasoline or diesel contained therein ignites. Like all liquids, both fuels only burn on the surface. The reason: fire not only needs fuel, but also oxygen so that it does not go out. A fire in a car usually only spreads slowly: it can take up to eight minutes for a car to catch fire completely.

How often do cars really burn?

Vehicle fires are among the rarest types of accidents or breakdowns. Based on the total number of accidents, the risk of a vehicle fire is less than one percent.

Why do cars explode?

Usually there is no explosion. This can only happen if there is a gas mixture in the tank - i.e. the evaporation of the fuel and in combination with oxygen. But that only happens if, for example, the tank is almost empty and an ignition source such as a cigarette is added.

Do electric cars burn more often than normal vehicles?

The risk of fire is comparatively low, since current electric cars are just as safe in an accident as conventional cars and the high-voltage system is usually switched off after an accident when the airbag is triggered.

At what impact speed does a car blow up?

In general, there is no limit above which an explosion is likely or even inevitable. Anytime fuel or oil leaks and sparks form, a fire can result. The fire would then have to penetrate into the tank, which - see above - would have to contain an air-gasoline mixture. The likelihood of that happening is very slim.

What should drivers do if their car is on fire?

When a fire breaks out, sparks can fly, which is dangerous. In addition, the resulting smoke gases are poisonous. Motorists can endanger their lives as a result, so they should leave the vehicle immediately and move away quickly. You should also alert the fire brigade (112) and police (110) immediately. Nevertheless, please don't panic: In the event of a vehicle fire, there is usually enough time to get out of the car to safety - and to rescue injured occupants if necessary.
