Redesigned from the ground up, the 2010 Buick LaCrosse will make its world debut next week at the North American International Auto Show in Detroit. The LaCrosse offers all wheel drive, a suite of advanced intelligent personal technologies and safety features, and a choice of two fuel-saving V-6 engines. The 2010 LaCrosse will be offered in three models -- CX, CXL and CXS -- and goes into production this summer.
