ARLINGTON, VA - The Insurance Institute for Highway Safety said it has given its 2010 Top Safety Pick award to both the Hyundai Genesis and the redesigned Mercedes-Benz E-Class. 

The large luxury cars, IIHS said, earned the top rating of "good" for front, side, rollover, and rear crash protection. Both also have electronic stability control as standard. 

The Genesis was introduced in the 2009 model year. During the 2010 model year, Hyundai made changes to the roof structure to improve protection in rollover crashes. The Top Safety Pick award applies to Genesis models built after January 2010. 

The E-Class was redesigned for the 2010 model year. This is the first time the E-Class has earned the institute's top safety designation. Earlier this year, design changes were made to the padding in the front and rear doors to improve protection in side-impact crashes. The Top Safety Pick award applies to E-Class models built after March 2010.
