US Institute for Highway Safety testing results show that some automakers are paying much attention to the development of the vehicle roof strength rollover case, which are made much better than current federal standards require. And the roof of some other developers, need to be improved.
SUVs that earned good grades – 2018-2019 Chevrolet Equinox release in March , Jeep Liberty (Dodge Nitro), Toyota Highlander and the Venza, as well as the Jeep Grand Cherokee and Kia Sorento – model.
Ford Edge is estimated acceptable. Minimum evaluation earned Honda Accord Crosstour, Honda Pilot, Mazda CX-7, Mitsubishi Endeavor, and Nissan Murano – all models.
Besides the fact that Grand Cherokee, Highlander, Sorento, and Venza have earned good grades, they have been awarded Top Safety Pick US security institute. To achieve this, the vehicle must be sure to protect occupants in a rollover, and the vehicle must have electronic stability control.
Institute of Research has shown that the roof of the car to be more than twice as strong as the minimum required in accordance with current federal safety standards. Strength Assessment Program conducted Institute for informing customers. Rollover test is designed to help consumers choose a vehicle that will protect itself in case of a serious accident.
“We tested the mid-size SUVs, as a huge number of users,” says Institute president Adrian Lund. “The first results show that automakers are making progress in protection against tipping, but disappointed by the fact that the new design, like Crosstour does not protect better.”
When testing the press presses on the angle of the roof at a constant speed. In order to get a good grade, the roof should withstand the force of 4 vehicle weight not exceeding 5 inches of deflection. Suitably, the minimum ratio of strength to weight is 3.25. Bad ratio – 2.5, and anything below. Grand Cherokee, Highlander, Liberty, and Venza withstood forces of nearly 5 times their weight.
With a good assessment (4 or more), the percentage of serious injury or death is reduced by 50 percent. The current federal standard operating only 1.5.
