LaCrosse eAssist video

In its latest 30-second advertisement pitching the 2012 LaCrosse eAssist, Buick makes an interesting point: since people don't constantly run in place, its near-luxury mid-size sedan doesn't either.

The ad thus extolls the virtues of eAssist, a fuel-saving mild hybrid setup with stop-start technology available in the LaCrosse. Because of Buick's simple – but, indeed, quite clever spot – the general buying public should comprehend eAssist: it shuts down the 2012 LaCrosse's gas-burning 2.4-liter Ecotec engine when not in motion.

Thanks to eAssist technology, the $30,820 2012 LaCrosse, which is indeed quite a porker (3,829 to 4,045 pounds), returns 25 miles per gallon in the city and a rather impressive 36 mpg highway. Buick says eAssist, is a "technology that shifts from gas to electric power, and back, seamlessly." And that's all Buick is trying to say, and you can check it out for yourself after the jump.
