The decision by global automakers almost 10 years ago to design the front ends of SUVs and pickup trucks so their energy-absorbing structures would align better with those of cars has paid dividends in lives saved. According to the Insurance Institute for Highway Safety (IIHS), the front-end-design measure is a major reason why the fatality rate in crashes among certain types of vehicles plummeted two-thirds from 44 per million registered vehicles in 2000-2001 to 16 in 2008-2009. Those fatality rates apply to crashes between SUVs and cars/minivans of roughly the same weight (3000-2499 lb; 1361-1587 kg). Also credited with the fatality rate reduction was a separate decision by the automakers to improve side-impact protection, mainly by installing side airbags. This video from IIHS shows how engineering design affects crash dynamics.
