Even more inconsistencies in an insurance company's crash test: the electric cars had no battery cells on board.

The fire at a Tesla was faked.

Update from August 30, 2022, 9:40 a.m.:

The alleged crash test by Axa insurance is increasingly turning out to be a show event without any real gain in knowledge: As the company admitted at the request of 24auto.de, there were no batteries in the tested vehicles .

According to the press office, "demonstrating a battery fire would have been too dangerous due to the guests present, which is why the battery cells of the electric cars were removed before the tests".

With the same reasoning, the insurance company had also ignited the fire of a tested Tesla Model S with pyrotechnics itself.

Fake fire in crash test: electric cars had no batteries

Instead of using their own power, the cars were driven "by a towing vehicle via a tow bar".

This can also be seen in the photos and videos.

An external drive (but not the removal of important components) is also quite common in serious crash tests, after all there is no driver behind the wheel, but at most a dummy.

However, removing the batteries, which has an impact on stiffness and weight, may have changed the crash behavior.

Fake fire in crash test: ADAC sees no risk in electric cars

The statement by the Axa Crash Show that electric cars (because of their batteries!) can pose a particular risk in a crash contradicts other tests.

This is how the ADAC judged after corresponding crash drives in its technical center in Landberg am Lech: “None of the current electric cars have so far had negative results in a crash test.

Compared to conventionally powered cars, the safety of electric cars is often even better because of the optimized crash structure in the vehicle."

First report from August 26, 2022, 11:28 a.m.:

Are cars with electric drives less safe than conventional ones?

Not only since the EU decided to ban internal combustion engines from 2035 has this question been on the minds of many motorists.

Above all, the risk of fires (whether in individual cases like this Tesla or due to production errors in the batteries like the Chevrolet Bolt) is a recurring topic.

Overall, based on previous practical experience, the risk with electric vehicles does not appear to be greater than with combustion engines.

The insurance group Axa wanted to know exactly and publicly drove two crash tests with electric cars.

The first focused on the vulnerable underbody with the batteries placed there.

The experts simulated an accident that was triggered by the motor power of electric cars, which took some getting used to: “Most electric cars, especially the powerful ones, have a very high torque, which is immediately noticeable when you tap the power pedal.

This can result in unwanted, jerky acceleration that the driver can no longer control,” explains Michael Pfäffli, Head of Accident Research at AXA Switzerland.

In the crash test, it was assumed that the driver would lose control of a Tesla Model S when accelerating, which would then overturn on a traffic island.

Fake fire in crash test: insurance company ignites Tesla itself

The passenger compartment remained intact, but the underbody was actually badly damaged.

Although the drive battery is very well protected by additional stiffening of the body at the front, rear and sides, according to the Axa researchers, such severe damage could pose a fire hazard: the Axa photo and the videos made available to the media show that also to see how the Stromer burns.

However, the spectacular shot showed a fake fire.

Because the battery had not ignited by itself during the crash.

"For safety reasons, it was not possible to ignite a real battery fire at an event with around 500 people, which is why a fire with pyrotechnics was staged," said the Axa press office in Cologne at the request of 24auto.de: "We wanted to use the fire the accident researchers: on the one hand point out the danger of a cell fire, which can result from damage to the underside of the electric car, and on the other hand point out the problems with fires in electric vehicles in general.

Fortunately, fires are very rare in electric cars as well as in conventional combustion engines.

The other crash test simulated a frontal impact at 50 km/h between a conventionally powered VW Golf VII and the electric version.

It should draw attention to the different weight classes: The e-Golf weighs around 400 kilograms more than the combustion engine.

The result: the lighter vehicle is at a disadvantage in a crash because the energy load is greater than the heavier one with batteries.

However, since both vehicles have modern safety systems, the effects of the mass difference are compensated and the passenger compartments remain intact.

However, it would look different if older models without modern safety equipment were involved in an accident.

Drivers of heavy vehicles, such as battery-electric vehicles, should therefore be particularly careful and considerate when driving, according to the insurance company.
