According to the IIHS (Insurance Institute for Highway Safety) in the US, which has much stricter regulations for vehicle safety than government levels, has rated the 2008-2009 Lancer as "GOOD" on frontal offset crash tests. In addition, the IIHS rated the 2008-2009 Lancer as "GOOD" on the side impact tests with the optional side airbags installed.
In my experience (I have been in 3 major collisions in my life) the seatbelt is your primary friend. It helps to keep your body from moving around in the case of a collision or rollover. The airbags have a certain threshold for them to activate. Taking me for example again, when I rolled my previous Jeep, NONE of the airbags deployed. This was because none of the sensors experienced enough force (I didn't have curtain airbags installed) for the front bags to deploy.
The Lancer is a very well built car in a structural sense; I remember doing alot of research on the body and how it was constructed. I believe the Unibody design was what really convinced me about the structural integrity of the car. So I would not fret about it; it is the car's job to keep you safe in the event of a collision. It is your job to keep the car safe from collisions (IMG:
