Acura RDX and BMW 3 series earn IIHS Top Safety Pick award
The 2013 RDX and 2012 3 series, both redesigned models, earn the
Institute's top award for affording occupants good protection in
front, side, rollover and rear crashes.
The RDX, a midsize luxury SUV, and the 3 series, a midsize luxury car,
earn the award with improved roof strength for protection in rollover
crashes. Top Safety Pick only applies to the redesigned 4-door version
of the 3 series.
To measure roof strength, a metal plate is pushed against one corner
of a vehicle's roof at a constant speed. The maximum force sustained
by the roof before 5 inches of crush is compared to the vehicle's
weight to find the strength-to-weight ratio. This is a good assessment
of occupant protection in rollovers.
The 2007-12 RDX was rated marginal for roof strength. The 2006-11 3
series was rated acceptable
