For 2011 Buick will replace the entry-level 3.0-liter V6 engine offered in the LaCrosse with a new 2.4-liter 4-cylinder. The 4-cylinder isn't likely to make for spritely performance, but it does do a more than capable job as the entry-level offering in numerous other GM products including the Chevy Equinox.
Power for the new direct-injection 2.4-liter 4-cylinder Ecotec engine is rated at 182-hp and 172 ft-lbs of torque and when mated to a six-speed automatic transmission, delivers EPA rated fuel economy numbers of 19-mpg city and 30-mpg highway.
As a result of these changes, Buick will now also offer all-wheel drive on the top-trim 3.6-liter V6 models.
Unfortunately, with the base LaCrosse CX trim now coming with a 4-cylinder, the price hasn't droped as much as you'd expect. A base LaCrosse now starts from $26,995 – just $90 less than last year's V6.
