New Car Safety Technologies Promise Increases In Fuel Economy

"For years, the accepted wisdom in the car industry held that, all things being equal, heavier vehicles are always safer when two vehicles crash. New studies highlight how other factors -- including a car's size, body design and advanced technology -- can do much to counteract the weight issue.

...The newer studies also have homed in on the downside of weight: While a heavy vehicle protects its occupants in an accident, it inflicts more damage to those it hits. That means reducing the weight of the biggest vehicles could yield dividends in both fuel consumption and safety.

All of this has contributed to a rethinking of the fuel-economy regulations from the National Highway Traffic Safety Administration. Last month, NHTSA crafted new "Corporate Average Fuel Economy" rules, or CAFE, for light trucks that aim to balance safety and fuel efficiency."
