Buick wants to continue the progress that made it the fastest-growing luxury brand in 2010, when sales climbed 52%, making it fourth among luxury brands. The Verano is "Buick's first ever compact luxury sedan," said Jim Schwegman, U.S. marketing VP. He said the car brings "compact fuel economy in a standard full-sized sedan." It starts at about $30,000. Jim Federico, chief engineer for Verano, noted "this will be the quietest compact sedan on the market." Buick developed 50 new "quiet enablers," he said, including tougher assembly sealing standards, stiff body structure, thick, acoustic glass and triple door seals.
