The list of winners of the Insurance Institute for Highway Safety's Top Safety Pick award is longer than ever this year, with vehicles in nearly every size category the Institute evaluates earning accolades. From minicars to sedans to pickups, consumers have a record number of choices among 2012 models.
In all, 69 cars, 38 SUVs, 5 minivans, and 3 pickups earn Top Safety Pick. The award recognizes vehicles that do the best job of protecting people in front, side, rollover, and rear crashes based on ratings in Institute evaluations. The ratings, which cover all 4 of the most common kinds of crashes, help shoppers pick vehicles that offer the highest levels of crash protection. Because the federal government now requires all 2012 and later passenger vehicles to have electronic stability control to help drivers avoid loss-of-control crashes, ESC no longer is a requirement to win as it was in prior years.
The winners' circle includes 18 new recipients for 2012, while 97 models that previously qualified for the 2011 award carry over to 2012.
"For the second year running a record number of models qualify," says Institute president Adrian Lund. "It's tough to win, and we commend auto manufacturers for making safety a top priority."
That commitment to protecting people in crashes is evident in the fast pace of design improvements automakers have made during the past year. Initially 66 vehicles qualified for last year's award as less-than-perfect rollover ratings held back many contenders. Later the number climbed to 100 as manufacturers redesigned roofs to make them stronger or introduced new models to win. The Institute's rolling test schedule allows for recognition of additional winners throughout the year, so many 2012 models qualified for a 2011 Top Safety Pick.
About the award: The Institute awarded the first Top Safety Pick to 2006 models and then raised the bar the next year by requiring good rear test results and ESC as either standard or optional equipment. In 2010, the Institute toughened criteria by adding a requirement that all qualifiers must earn a good rating for performance in a roof strength test to assess protection in a rollover crash.
The Institute groups winners according to vehicle type and size. Lund advises consumers to keep in mind that size and weight influence crashworthiness. Larger, heavier vehicles generally afford better occupant protection in serious crashes than smaller, lighter ones. Even with a Top Safety Pick, a small car isn't as crashworthy as a bigger one.
How vehicles are evaluated: The Institute's frontal crashworthiness evaluations are based on results of 40 mph frontal offset crash tests. Each vehicle's overall evaluation is based on measurements of intrusion into the occupant compartment, injury measures recorded on a 50th percentile male Hybrid III dummy in the driver seat, and analysis of slow-motion film to assess how well the restraint system controlled dummy movement during the test.
Side evaluations are based on performance in a crash test in which the side of a vehicle is struck by a barrier moving at 31 mph. The barrier represents the front end of a pickup or SUV. Ratings reflect injury measures recorded on 2 instrumented SID-IIs dummies representing a 5th percentile woman, assessment of head protection countermeasures, and the vehicle's structural performance during the impact.
In the roof strength test, a metal plate is pushed against 1 side of a roof at a displacement rate of 0.2 inch per second. To earn a good rating for rollover protection, the roof must withstand a force of 4 times the vehicle's weight before reaching 5 inches of crush. This is called a strength-to-weight ratio.
Rear crash protection is rated according to a 2-step procedure. Starting points for the ratings are measurements of head restraint geometry — the height of a restraint and its horizontal distance behind the back of the head of an average-size man.
Seat/head restraints with good or acceptable geometry are tested dynamically using a dummy that measures forces on the neck. This test simulates a collision in which a stationary vehicle is struck in the rear at 20 mph. Seats without good or acceptable geometry are rated poor overall because they can't be positioned to protect many people.
2012 winners include:
Chrysler 200 4-door, Chrysler 300, Chrysler Town & Country, Jeep Patriot, and Jeep Grand Cherokee.
