Under the same deceleration ( say you hit a stationary object ) or the same initial speed ... the more mass you have the more impact energy you have. Mass increases the impact energy not decreases it... Mass doesn't absorb the impact energy , it increases it.
A better design is a better design ... that part I'll give you ... but the mass part you have backwards.

I said energy absorbed INTO the structure, rather than transferred kinetic energy.

Hmmm I guess. I also forgot that SUVs tend to be a lot higher and so the strength of the doors is less relevant since you'd be getting hit closer to the frame. My bad.
