The 2013 Buick LaCrosse is a midsize premium sedan offering a blend of style, comfort, and technology. Part of the third generation, it is available in five trim levels: Base, Leather, Premium 1, Premium 2 and Touring. A 182-horsepower 2.4L four-cylinder hybrid powertrain comes standard, while a more potent 303-hp 3.6L V6 is also available. Both are paired with a six-speed automatic transmission. Standard features include a 7-inch touchscreen, keyless entry/start, and dual-zone automatic climate control, while higher trims offer advanced safety features like adaptive cruise control and blind-spot monitoring. Notably, 2013 was the year Buick introduced the IntelliLink infotainment system across the LaCrosse line, providing voice command and smartphone integration capabilities.
