IIHS Crash probó su vehículo más pesado para prepararse para vehículos eléctricos masivos

Los vehículos eléctricos son realmente pesados, y eso es una mala noticia para nuestras carreteras, nuestro medio ambiente y la capacidad de supervivencia de los pasajeros en los accidentes. El aumento de peso también complica las cosas para los grupos de vigilancia de seguridad dedicados a las pruebas de choque de vehículos nuevos. El Instituto de Seguros para la Seguridad en las Carreteras tuvo que montar los vehículos más pesados ​​que jamás haya probado para asegurarse de que su equipo de evaluación esté a la altura del desafío.

El IIHS cargó algunos vehículos más antiguos con placas de acero y bloques de hormigón para replicar el peso de algunos de los vehículos eléctricos más pesados ​​que se dirigen al mercado, como el gigantesco Hummer EV, que pesa alrededor de 9500 libras. Solo las baterías del Hummer eléctrico pesan más que un Miata completo.

Naturally, the IIHS doesn’t drive vehicles into concrete pylons under their own power. The agency uses a propulsion system consisting of a tow cable that gets hooked to the vehicle and brings it to a speed of 40 mph over just 600 feet. This battery of tests with extra-heavy vehicles was meant to ensure the 20-year-old “crash machine” is up to the task with increasingly massive vehicles.

Since the IIHS only needed to test the strength of the system, the agency didn’t need to consume a real and extremely expensive EV. Instead, they loaded up some older model vehicles and slammed them into the concrete. The 9,500-pound test vehicles represents the heaviest automobiles IIHS has ever smashed in its testing facility, knocking the sub-6,000 pound 2019 Audi E-Tron out of first place.

Crashing EVs can be a risky business. Joe Young, Media Relations Director at IIHS, told Jalopnik there are special considerations when crash-testing a battery-powered vehicle.

“We do test with the batteries in place (at a charge of about 12.5 percent), and we closely monitor the battery temperature during and after the crash,” Young said. “We also have some special precautions in place to ensure that the vehicle chassis is not electrified before our technicians start doing post-crash analysis. And there are special precautions in place to move the vehicle outside quickly and safely if there were a problem.” So far, IIHS has never had an EV catch fire during crash testing, but it pays to be prepared, because battery fires are no joke.

Heavy electric cars, however, are likely to make a bad problem on U.S. roads even worse. Not to be a broken record, but traffic deaths reached a 16-year high in 2021 and this year is not looking much better. Part of the reason for this higher fatality rate, especially among pedestrians, is the increasing presence of heavy, large SUVs and trucks on the roads. The IIHS’ own studies show that such vehicles are more likely to kill pedestrians and other vulnerable road users. It seems another way we could easily cut down on traffic deaths would be to restrict the size and weight of mainstream vehicles, but considering automakers make bank on such vehicles, that solution is likely a non-starter.
