2016 Volvo XC90 small overlap IIHS crash test
Crash Test Ratings What is the difference between IIHS and NHTSA.
If you are a customer of car safety conscious, you probably checked crash test ratings on all vehicles you are considering But with two groups - the Insurance Institute for Highway Safety IIHS and Administration National Highway NHTSA Traffic Safety - running different tests, how do you know which ones to look explain the differences.
There are several differences between IIHS and NHTSA, the most important is that the NHTSA is a federal government agency, while IIHS is a nonprofit group funded by insurance companies Of course, this has little impact on the ability of groups to test both cars carry out thorough tests on several aspects of vehicle safety, but they come with their scores using different scoring systems and tests.
The crash test ratings from NHTSA uses a star system, where a star suggests poor performance of crash test and five stars is excellent rating indicates exceptional performance The exact meaning of a star depends on the test, for example in the rollover test, five stars indicates a low probability of rollover, while five stars in the side impact test indicates a low probability of serious injury.
The NHTSA rating system comprises three tests The first is a frontal test that measures the probability that the driver or passengers injury when a vehicle accident in a fixed barrier at 35 miles per hour then is an impact assessment side, which requires an average of a vehicle performance on two trials in the former, the car being evaluated is struck from the side of a vehicle of 3000 lb moving at 5 mph NHTSA 38 then measures the likelihood of injury for front and rear passengers Side- the second test the component impact extent likely to lead to injury in a 20 mph side impact with a pole.
A final test NHTSA is working side Interestingly, this n t test at all, but rather a mathematical formula that takes into account the width and center of gravity of a car While NHTSA really doesn t test vehicles for rollover risk, the agency argues that this test is valid after comparison with the statistics of car accidents.
Once NHTSA conducted three tests - the impact front and two side impact tests - and added the figures for the assessment roll, an overall rating is given, again on a scale of 1 to 5 stars this indicates the overall crashworthiness car.
IIHS crash tests carried out its a bit differently for one, it's no star system Instead, the agency ranks in vehicle four ways poor, marginal, acceptable and good, with good being the highest rating possible.
IIHS puts vehicles across five different crash tests There its test before small overlap, where 25 percent of the face width of the car hits a barrier 40mph It its moderate lookahead overlap, where a larger part of the the car hits the barrier of the test side, where a barrier SUV hits like cars at 31 mph it sa roof strength test where a metal plate is pushed against the roof of a car to see if it can easily collapse if reversal, SA and headrest-and-seat test, which measures the forces on a driver's head and neck in a collision IIHS has recently begun testing the safety equipment before the accident prevention, such as systems that prevent or warn drivers of imminent collision before.
According to a performance vehicle in the tests the IIHS, it can be given one of the two car prices that work well are awarded a Top Safety Pick designation, which indicates that the performance is well above average in their class cars that do a remarkable job are given an even more prestigious Top safety pick, which is a step above a simple Top safety pick designation.
As for crash tests, you can never be too careful So if you were wondering what tests are most important, our advice is simple look at a car that all aces both IIHS and NHTSA tests will surely be a good choice, while one who earns more moderate scores may not be the best choice if security is your main concern anyway, now you have all the facts on how IIHS and NHTSA conduct their tests collision, so you can make the most informed decision possible.
