General Motors and Toyota Motor Corp. are gearing up to produce hybrid gasoline-and-electric versions of sport utility vehicles and pickup trucks, giving fuel-saving hybrid technologies a big push toward the mainstream market, according to the Wall Street Journal. At the annual Detroit auto show next month, Toyota and GM will announce plans to introduce hybrid versions of several of their bigger vehicles, the Journal said. GM, the world's biggest automaker, intends to roll out hybrid systems as optional equipment across much of its lineup between 2004 and the end of the decade, according to an official familiar with the plans. Toyota will disclose plans to launch hybrid versions of its Lexus RX330 luxury SUV and its Toyota Highlander SUV before the middle of the decade, according to the Journal.
