A viral video made headlines, including ours, showing a 2022 Rivian R1T smashing done a guardrail arsenic though it were made of bedewed insubstantial towels during a University of Nebraska-Lincoln test. This brought a awesome woody of attraction to nan truth that electric vehicles are dense and going to termination america all. Certainly, the Rivian's weight of 7,173 pounds was a facet successful nan guardrail's ineffectiveness astatine stopping specified a brute. However, an investigation by The Drive shows that nan little halfway of gravity that astir EVs person plays a important domiciled arsenic well.
According to Cody Stolle, nan adjunct head of nan Midwest Roadside Safety Facility, wherever nan trial took place, specified tests typically usage a 2,400-pound subcompact sedan, representing nan debased extremity of conveyance weight, and a 5,000-lb pickup truck, typically a Ram 1500, connected nan precocious end. The Rivian weighs almost arsenic overmuch arsenic these 2 vehicles combined. While surely an outlier for really these tests person been conducted up until now, nan proliferation of EVs connected nan roadworthy intends much and much dense vehicles, acknowledgment to their monolithic artillery packs.
However, galore configurations of nan Ford Super Duty and different heavy-duty versions of accepted pickups are moreover heavier than nan Rivian R1T. Why aren't stories astir them slicing done guardrails and moving complete puppies each complete nan regular news?
Low riders
Weight is 1 thing, but wherever that weight is located connected nan car plays a important domiciled arsenic well. The University of Nebraska-Lincoln ran nan aforesaid guardrail clang trial connected a Tesla Model 3. It weighs 3,838 lbs, almost nan aforesaid arsenic nan low-slung Ford Mustang GT Fastback pinch a manual transmission. While Mustangs person a estimation for plowing into crowds, it's been proven that guardrails will extremity them. The Tesla, however, went correct done nan guardrail conscionable for illustration nan Rivian, contempt being almost half nan weight.
EVs typically spot their large, dense artillery packs astatine nan bottommost of nan car. This improves handling and performance, and moves nan wide halfway of gravity 5 to 8 inches little than accepted fossil fuel-powered vehicles. The dense engines and transmissions of state guzzlers beryllium higher successful nan car than an EV's artillery pack. Effectively, an EV's little halfway of gravity transfers astir of its effect unit into nan guardrail's little supports, not nan building that is designed to sorb impacts. That's why nan Tesla went nether nan guardrail alternatively than consecutive into it.
The problem is now twofold. Larger EVs measurement much than guardrails tin handle, but each EVs person a little halfway of gravity that transfers astir of nan effect unit to guardrails successful a different spot than they are designed to beryllium hit. The costs of upgrading our infrastructure to grip some EVs and accepted vehicles will beryllium immense.
