In addition to having eAssist added to its four-cylinder powertrain, the 2012 Buick LaCrosse is undergoing a few other changes. We aren't talking about styling or content tweaks – instead, General Motors is revising its packaging strategy for the LaCrosse. Buick will be ditching the CX, CXL and CXS trim level designations and simply offer large option packages that encompass all of the available amenities.
For 2012, the 2.4-liter Ecotec engine with eAssist technology will be offered as the "standard" powertrain. We recently had some very limited drive time with an eAssist-equipped LaCrosse (stay tuned for our full impressions), and found the four-cylinder with 182 horsepower and 172 pound-feet of torque to be pleasantly adequate and its highway rating of 37 miles per gallon downright remarkable. eAssist-equipped cars will look no different than other LaCrosses, save the addition of model-specific 17-inch wheels on efficiency-optimized tires and other fuel-saving upgrades not visible from outside the car.
