General Motors says it is focused on rebuilding its historical strength in passenger cars while broadening its current strength in trucks as it enters the 2004 model year in the United States. "GM today is leaner, faster, more flexible and more efficient," said marketing and advertising head John Middlebrook. "We're focused like a laser on bringing to market the kind of well-built, stylish, innovative vehicles that GM was known for when it was the undisputed automotive leader."
