Safety technology has improved by leaps and bounds over the last few decades, and just about every automaker now knows how to score a five star rating from the National Highway Traffic Safety Administration. Toyota is looking to keep the stars coming by developing a new rear window airbag that will be standard equipment on its upcoming iQ micro car. A quick glance at micro-vehicles like the iQ shows that there is very little space between the back seat and the rear window, which means there won't be as much metal to absorb the impact of a rear collision. With Toyota's new rear window airbag, the rear air bag is ejected from the roof lining during a fender bender. Toyota says it will help protect the heads and necks back seat passengers, which is all the more important in smaller vehicles like the iQ. In addition to this new bag, Toyota wants to improve its safety reputation by making side curtain and shield airbags standard for all of itsmodels.
