Newer cars are more rigid in just the right places (e.g. driver cage) - they do have larger/softer crumple zones that permit the damage to be absorbed along a longer time period. By prolonging the total crumple/crash time, the peak energy is decreased, thereby avoiding injuries from force overload during deceleration.

Knowing that, one should also be able to conclude this Focus crash test is meaningless. How it performs vs. an immovable wall at 120mph really doesn't tell you much about how it will perform at 65mph vs. a fence, or a tree, or a guard rail. If it didn't crumple at 120mph, then you'd have cause to worry though.
