The 2010 Buick LaCrosse is getting a new engine option--but GNX fans won't be impressed to hear that the new option is a four-cylinder engine.
The new four-cylinder is a 2.4-liter engine, and GM's fitted direct injection to it to boost power and fuel mileage. Available in the CX model, this engine will put out 182 horsepower and 172 pound-feet of torque. It will give the LaCrosse estimated fuel economy of 20/30 mpg, putting it in striking range of the four-cylinder Honda Accord in the mid-size segment.
In the LaCrosse, the four-cylinder will be teamed with a six-speed automatic--a nearly identical installation to the one found in the 2009 Chevrolet Malibu, which shares mechanicals with the new LaCrosse. GM adds the four-cylinder gives the LaCrosse a miserly edge not found in the Acura TL or the Lincoln MKZ, in case you're wondering which other vehicles they see as key competitors.
Upmarket versions of the 2010 LaCrosse will get a 3.0-liter V-6 or a 3.6-liter V-6. The 2010 Ford Taurus, by comparison, will make do with just the base 3.5-liter V-6 and the SHO's EcoBoost V-6.
The 2010 LaCrosse CX won't be the brand's only four-cylinder car. A 2012 Buick Century is a distinct possibility--a new compact sedan based on the 2011 Chevrolet Cruze has been spotted by spy photographers, wearing distinctive Buick cues from the shield badges and grille down to a brand-unique steering wheel.
