2012 Buick LaCrosse is officially set to get bigger 3.6L V6 engine


The recent announcement of GM’s eAssist Technology that will be used in 2012 Buick LaCrosse to help provide a fuel economy rating as much as 37 miles per gallon on the highway in the four-cylinder engine, but that didn’t deter GM from offering a bigger engine for the new Buick LaCrosse.

GM just announced the new 3.6-liter V6 engine for the 2012 Buick LaCrosse. The V6 engine will be available as a no-cost option, which means that customers will have a choice between the four-cylinder engine with eAssist or the 3.6-liter engine at the same price.

The 3.6-liter direct-injected V6 engine is estimated to produce about 303 horsepower and 264 pound-feet of torque, which is an increase of 23 hp over the current 2011 model. Buick claims that with the added horsepower, overall efficiency remains the same; the V6 LaCrosse still has the same fuel economy rating of 17/27 city/highway mile per gallon.

“As a result, there is more power without sacrificing fuel economy,” Sutter said. “The more-efficient combustion also means reduced emissions.”

The 2012 Buick LaCrosse will start production this summer.
