![]() “We tell consumers: What you really should be looking for is no less than four stars from the government and a Good or Top Safety Pick recommendation from us.The resultant vector of the addition of vectors a → and b → is r →. The next-best rating of Top Safety Pick goes to vehicles that earn those same top ratings in the five crash tests and front crash-prevention equipment performance but can score only Acceptable in headlights Top Safety Pick award does not require a Good or Acceptable rating in the passenger-side small-overlap front test.“We develop tests not to necessarily supplant what NHTSA is producing, but to augment it,” said Joe Nolan, chief administrative officer and senior vice president for vehicle research at the IIHS test facility in Ruckersville, Virginia. We've actually conducted our very-own automated braking test on four-different models at an IIHS facility. The car also must score a rating of Advanced or Superior in driving tests related to the effectiveness of front crash-prevention systems such as automated emergency braking. It must also earn a Good or Acceptable rating for headlights. These tests include driver's-side small-overlap front, moderate-overlap front, side, roof-strength, passenger-side small-overlap test, and head-restraint crash tests. To earn it, a car must score Good ratings in all six crash tests. Other factors-such as the effectiveness of a vehicle’s headlights, the ease of using child-seat anchors (LATCH), and the performance of safety systems such as automated emergency braking-are factored into a vehicle's overall score.The IIHS's highest rating is Top Safety Pick+. Ratings are Good, Acceptable, Marginal, or Poor. Like NHTSA, it generally chooses vehicles that sell in high numbers and are new or significantly updated. IIHS Picks Its Safest CarsĪn insurance-industry-backed nonprofit organization, the IIHS conducts its own series of six crash tests on over 100 new vehicles each year. ![]() Calspan's 58,000-square-foot test lab features two crash halls and is used to test everything from production cars and prototypes to motorcycles and heavy-duty trucks. “In the scheme of running a test, we provide a completely unbiased result.” Goupil says car-focused clients include government agencies (like NHTSA, which is part of the Department of Transportation) or car companies that don't have the capacity or infrastructure needed to run certain tests. “We have no ties to anyone,” said Gerald Goupil, Calspan's director of vehicle crash testing. One of these is Calspan Corporation, an engineering and research firm based in Buffalo, New York. NHTSA's tests are performed by several independent facilities located around the United States. That means a car such as the redesigned Kia K5 would be tested but not a limited-edition sports car or a carryover volume model. The federal agency now conducts 90 to 125 tests annually on high-volume models that are new or significantly updated for a given model year. Ratings are given for each test as well as overall, with five stars being the top score. NHTSA started wrecking cars in 1978 to test their performance during frontal-impact crashes and later added side and rollover crash tests as well as lists of recommended safety technology to its New Car Assessment Program (NCAP). The two main players are the National Highway Traffic Safety Administration (NHTSA) and the Insurance Institute for Highway Safety (IIHS). Safety organizations have different methods of testing vehicles before assigning their ratings. But finding out a car's safety ratings-and how it earned those ratings-should be simple and stress-free. Buying a new car or truck can be nerve-racking, what with all the different options to choose from and the financial aspect of such a major transaction.
