The U.S. Transportation Department has announced their new 5 star safety rating system that will be used to rate the new 2011 automobile models. The safety rating program was first introduced in 1979, but changes were needed since almost 90% of vehicles tested under the old system received a five star rating. According to Transportation Secretary Ray LaHood, “Through new tests, better crash data and higher standards, we are making the safety ratings tougher and more meaningful for consumers.” “The new rating system will encourage auto makers to install crash avoidance technologies and will help shoppers buy a safer vehicle.”

The ‘Stars on Cars’ system uses an overall score rating. Different size test dummies are used and crash prevention technologies are included in the score. A new test that simulates a car striking a pole or a tree has also been added. The overall score combines the results of front, side and rollover tests and compares those results with average risk of injury and the potential for vehicle rollover. So far, of the 34 vehicles tested under the new program only two have received the top grade of five stars. BMW AG’s 2011 5 Series and a version of the 2011 Sonata from Hyundai Motor Co.

There will be a bit of confusion for consumers, when trying to compare safety of a 2010 model with a 2011 model, but automobile manufacturers expect consumers will embrace the new changes. The window sticker attached to vehicles in dealership lots will need to be redesigned and won’t include the overall score until the 2012 model year. Vehicles that haven’t been tested will be listed as “not rated”.
