Buick LaCrosse 2012
The 2012 Buick LaCrosse powerplant consists of a 2.4L Ecotec direct-injected four-cylinder engine paired with next-generation six-speed automatic transmission. Using the advanced power storage from its air-cooled lithium-ion battery, needed electrical boost can be utilized in various driving scenarios to optimize the engine and transmission. The LaCrosse delivers an estimated 36 mpg highway and 25 mpg city, thanks to the 115V lithium-ion battery and latest-generation 15-kW motor-generator unit. Buick LaCrosse with eAssist technology uses improved underbody aerodynamics for performance, as well as active control of front-end airflow, allowing the LaCrosse to hug the road for better vehicle stability and driving experience.
