The big news surrounding the 2012 Buick LaCrosse is the addition of General Motors‘ eAssist technology – a new powertrain that will help the big sedan achieve up to 37 miles per gallon on the highway. Buick will offer the eAssist four-cylinder as the standard engine in the 2012 LaCrosse, but The General’s 3.6-liter V6 will be available as a no-cost option, and GM has now confirmed that the six-cylinder powerplant will get a boost in power versus the 2011 LaCrosse.
For 2012, the 3.6-liter direct-injected V6 will churn out 303 horsepower and 264 pound-feet of torque – an increase of 23 hp versus the 2011 model. However, this added power will not result in any loss of overall efficiency, with GM stating that the V6 LaCrosse’s 17/27 city/highway mile-per-gallon ratings will remain intact.
The 2012 Buick LaCrosse will start production this summer. For the full details on the V6′s power increase, follow the jump for GM’s official press blast.
