What if you fly into barriers with a heavy electric car in the hundreds? The Americans answered this question.
The University of Nebraska conducted an experiment funded by the US Army Development Center. The goal was to examine the safety issues raised by the increasing number of electric vehicles on America’s highways. They thus organized an unconventional crash test, where the main actor was the Rivian R1T electric pick-up truck. The latter was sent at a speed of 60 miles per hour, i.e. 96 km/h, at an angle against the barriers that follow the concrete blocks.
The technical data of the car indicates a weight of 7148 pounds, i.e. 3242 kilograms. After the impact, the car almost tore the guardrails apart and then happily continued on into the concrete blocks. An accident would be devastating. The situation in the Czech Republic might not be so different. The tested guardrails were made of corrugated steel with a thickness of approximately 2.6 mm. The seductress in the Czech Republic has a thickness of 2.6 to 3.0 mm, and we often have more elaborate ones.
The trapdoors in America were set 15 centimeters into the ground, but the car did not tear them out, rather it tore apart the support between the posts and the trapdoor itself. You can watch the video above. It is true that electric cars are heavier than cars with internal combustion engines. But they are far from being heavier than trucks, whose accident in a similar situation would have much worse consequences. On the other hand, we had a Ram 1500 here for the test in loaded Longhorn trim and it weighed 2479kg.
