Apples to oranges.... The GM Vehicles you had may have all been full frame vehicles (not uni-body) and that is typically the reason they do not crumble during collisions. This is actually not a good feature (in most situations) since the frame transfers the collision force into the human body causing severe damage during a major collision. It is nice to have a frame during a minor collision (less visible damage) and when hitting a much smaller vehicle (not great for the smaller vehicle) but generally uni-body vehicles are safer.MClady88 said:They took beating (in mileage and sometimes in physical hits) and held up way better than other car manufacturers I have seen. I've seen super expensive import cars crumple under wrecks that our GM cars only got minor "flesh wounds". My husband's Trailblazer just got rear ended HARD and only light cosmetic damage -very impressive results ;D
You sacrifice the vehicle to save yourself with a uni-body design.
Very similar to a motorcycle helmet, you destroy the helmet during one crash and save your head. A full frame vehicle would be similar to wearing a concrete helmet.
