There is almost no reason to write about the new 2010 Subaru’s. If you arrive on scene of a MVA with entrapment in a Subaru vehicle you can safely assume you will encounter some UHSS and most likely Boron. Here is what Subaru says about the 2010 Subaru Outback:
Subaru reinforces the key structural elements of its vehicles by building them with the most durable high-tensile steel. Because we see so much of the frame as key to your safety, nearly 40% of our Ring-shaped Reinforcement Frame is constructed of high-tensile steel.
One option to consider if you have an entraped occupant is the trunk tunneling techique. The liftgate opening in large enough to slide a patient out on a backboard.
