General Motors Corp. and Ford Motor Co. said they would add new electronic systems to sport utility vehicles to help prevent rollover accidents.
GM said it would make so-called electronic stability control systems standard equipment on 1.3 million SUVs, including the Chevrolet TrailBlazer and the GMC Yukon. Ford said it would add electronics to three models that sense when the vehicles start to tip.
GM said it would begin making the stability control systems standard on large SUVs immediately and expand them to mid-size models starting next year.
Ford’s new technology will become standard equipment on 2005 models of the Explorer and Mercury Mountaineer and available as an option for $595 for the Ford Expedition.
