Well, shoot. Yet another things that shows the push for EVs is not ready for primetime
Crash tests indicate nation’s guardrail system can’t handle heavy electric vehicles
Electric vehicles that typically weigh more than gasoline-powered cars can easily crash through steel highway guardrails that are not designed to withstand the extra force, raising concerns about the nation’s roadside safety system, according to crash test data released Wednesday by the University of Nebraska.
Electric vehicles typically weigh 20% to 50% more than gas-powered vehicles thanks to batteries that can weigh almost as much as a small gas-powered car. And they have lower centers of gravity. Because of these differences, guardrails can do little to stop electric vehicles from pushing through barriers typically made of steel.
Last fall, engineers at Nebraska’s Midwest Roadside Safety Facility watched as an electric-powered pickup truck hurtled toward a guardrail installed on the facility’s testing ground on the edge of the local municipal airport. The nearly 4-ton (3.6 metric ton) 2022 Rivian R1T tore through the metal guardrail and hardly slowed until hitting a concrete barrier yards away on the other side.
“We knew it was going to be an extremely demanding test of the roadside safety system,” said Cody Stolle with the facility. “The system was not made to handle vehicles greater than 5,000 pounds.”
On the brightside, after slamming through the guardrails the vehicles did offer fantastic protection for the passengers
But the entire purpose of guardrails, found along tens of thousands of miles of roadway, is to help keep passenger vehicles from leaving the road, said Michael Brooks, executive director of the nonprofit Center for Auto Safety. Guardrails are intended to keep cars from careening off the road at critical areas, such as over bridges and waterways, near the edges of cliffs and ravines and over rocky terrain, where injury and death in an off-the-road crash are much more likely.
“Guardrails are kind of a safety feature of last resort,” Brooks said. “I think what you’re seeing here is the real concern with EVs — their weight. There are a lot of new vehicles in this larger-size range coming out in that 7,000-pound range. And that’s a concern.”
In fairness, a lot of big vehicles are a problem, but, most EVs are sedans and compact SUV size, and the guardrails won’t save you. Have fun!
