2012 Buick LaCrosse eAssist

The eAssist is an updated mild-hybrid system for midsize sedan models of General Motors. The eAssist system is paired with 2012 Buick LaCrosse.

The 2012 Buick LaCrosse is a sharp-looking midsize sedan, Buick made a point of not changing 98 percent of the car’s exterior design in fitting it with the eAssist package. The LaCrosse’s large dimensions and wheel wells designed to properly house 19 -inchers at all four corners just make this eAssist-specific.

But what is the eAssist? The eAssist system enhances fuel mileage by “assisting” the gasoline engine, either by shutting down the engine when the car comes to a stop or cutting off the fuel supply when cruising or decelerating. The motor-generator continues spinning along with the engine to provide immediate and smooth take-off power when the driver presses on the accelerator.

This new BAS design has noteworthy fuel economy gains compared to the earlier system, but neither come close to fuel mileage delivered by a “full hybrid” operation. However, the eAssist is more complex and performs better than the “micro hybrid”stop-start systems deployed in the Porsche’s 2011 Cayenne and Panamera models. Buick’s eAssist is closer in function and fuel economy to the “mild hybrid” systems used in the Honda Insight and BMW ActiveHybrid 7.

Though the officially classified as a mid-size car, dimensionally the LaCrosse is closer to a large sedan. The LaCrosse never cuts costs with the choice of cabin materials. Even at night, drivers are rewarded with an ice blue ambient lighting package.

2012 Buick LaCrosse is powered by a 2.4-liter four-cylinder engine, produces a perfectly adequate 182 horsepower and 172 pound-feet of torque. The o-60 MPH time is about 2.6 seconds. Buick will offer the LaCrosse with eAssist as a no-cost option on the base car for the next model year; meaning buyers can select this setup or the V6 for the same price.

  1. The Buick E-Assist sounds like a great feature; especially when gas is so expensive right now and nearing over $4 a gallon in the states.
