ARLINGTON, VA - The Insurance Institute for Highway Safety has given Ford's re-engineered and restyled 2010 Mustang convertible the institute's highest rating of "good" for occupant protection in offset frontal crashes and side impacts. 

When the institute initially tested the 2010 model it earned a "poor" frontal rating, but the vehicle improved to a "good" rating in a follow-up test after Ford modified the front structure and doors of models made after December 2009. 

The institute also announced that the 2010 Acura MDX has earned a "good" rating for occupant protection in new side tests. Acura modified the side airbags in the current model of this midsize luxury SUV, which was redesigned for the 2007 model year. The 2007-2009 models also earned a "good" side rating. 

Moreover, IIHS noted that Toyota modified the 2010 Tundra's frontal airbags and safety belts and added knee airbags for the driver and front passenger to retain the "good" rating it earned for frontal protection for 2007-09 models. This large pickup had previously earned "good" ratings for side and rear protection, too.
