Buick added a new engine to the LaCrosse line-up: a new fuel-efficient, direct injected Ecotec 2.4L four-cylinder engine that delivers 182 hp and a peak torque of 172 lb-ft. The engine has a fuel economy of 30 mpg highway and 20 mpg city.
Every engine in the LaCrosse lineup is direct injected and matched with a fuel-saving six speed automatic transmission. Along with the Ecotec 2.4L, a new, direct injected 3.0L V-6 is offered and a larger-displacement, more powerful 3.6L V-6 is standard on the LaCrosse CXS model.
