The list of winners of the Institute'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 pickup trucks, 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 (see "More Top Safety Pick winners as rollover and side protection improve," Dec. 22, 2010). 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.
Top Safety Picks by manufacturer, April vs. December 2011
Again this year every major automaker has at least one winner. Subaru remains the only manufacturer with the distinction of earning awards for every model it builds. Subaru picks up 5 awards, including one for the redesigned Impreza, a small car.
Toyota/Lexus/Scion has 15 winners for 2012, more than any other auto manufacturer. General Motors is next in line with 14, followed by Volkswagen/Audi with 13, and Ford/Lincoln and Honda/Acura with 12 awards apiece.
Ten of the 18 new additions are Honda/Acura models, including the midsize Accord sedan, which hasn't earned Top Safety Pick since the Institute toughened criteria to win the 2010 award by adding a test to assess roof strength in a rollover crash (see "2010 Top Safety Pick: Criteria now include good roof strength," Nov. 18, 2009).
Vehicles rated good for rollover protection have roofs more than twice as strong as the current federal standard requires. The Institute estimates that such roofs reduce the risk of serious and fatal injury in single-vehicle rollovers by about 50 percent compared with roofs meeting the minimum requirement. A new federal standard for roof strength will phase in beginning with 2013 models (see "Rollover safety gets a big boost in new roof rule," June 11, 2009).

Roofs on the 2009 Honda CR-V and 2010 Pilot scored marginal ratings in prior Institute tests, while earlier models of the Accord, CR-Z, Fit, and Insight rated acceptable. Now all of these 2012 models earn good ratings and Top Safety Pick.
"Honda/Acura deserves credit for most-improved status," Lund says. "The automaker buckled down and upgraded roofs on 10 models that missed winning last year because of rollover protection. Now, the automaker has winners in the minicar, small car, midsize car, small SUV, midsize SUV, minivan, and large pickup categories."

Another midsize sedan, the Toyota Camry, earns its first-ever Top Safety Pick. Last year, the Camry missed the mark because of a marginal rating for seat/head restraints. The Toyota Yaris also earns its first Top Safety Pick award. Toyota upgraded the roof and seat/head restraints of the 4-door hatchback model to win. Good ratings secure the Yaris a spot alongside 3 other minicars, the Fiat 500, Ford Fiesta, and Honda Fit, as 2012 winners.
"It's great to see the Accord and Camry, 2 of the top-selling midsize cars in the U.S. market, join the Top Safety Pick ranks this year," Lund says. "The Accord previously won the 2009 award but has been missing from the list since then."
With fuel efficiency and reduced emissions on many buyers' wish lists, the winners' circle includes more green choices. Toyota's all-new Prius v is among them. Roomier than the original, the v brings to 15 the number of winners available as hybrids. The plug-in electric Chevrolet Volt and Nissan Leaf, winners in 2011, also earn this year's award.
For drivers who need to haul loads, the Ford F-150, Honda Ridgeline, and Toyota Tundra are good choices in the large pickup category. Small pickups continue to be shut out. None the Institute has evaluated qualify for the award.
"When we launched Top Safety Pick in 2005, consumers had 11 models to pick from. Six years later, finding a winner that fits most budgets and lifestyles is easy," Lund says. "It's a testament to the commitment automakers have made to going above and beyond minimum safety standards."
About the award
The Institute awarded the first Top Safety Pick to 2006 models (see "Institute announces Top Safety Picks," Dec. 17, 2005) 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.
Vehicle 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.
