It's not just the low hood (for crumple-area), but also the curve of the leading edge. In older SUVs (and still in today's full-size pickups) the front was squared-off and blunt, and this lead to people getting injured by that sharp edge. With the curved leading edge the pedestrians have a much more progressive landing on the hood. A car like the mid-70's Aston Martin Lagonda with it's knife-edge grill will never be built again. https://upload.wikimedia.org/wikipedia/commons/d/d6/Aston_Martin_Lagonda_West_London.jpg https://upload.wikimedia.org/wikipedia/commons/d/d6/Aston_Ma...
