2012 Buick Lacrosse with eAssist. Its here.

Buick’s innovative eAssist Technology improves your vehicle’s fuel efficiency by adding a compact electric motor and state-of-the-art lithium-ion battery to a 2.4L four-cylinder ECOTEC engine, improving fuel economy by an estimated 25%. The 2012 LaCrosse and Buick Regal will be the first vehicles available with eAssist Technology.

 Here a quick video on how it works.

Buick’s eAssist Technology is about improving fuel efficiency through innovations like:

*An automatic start/stop technology that shifts from gas to electric power and back seamlessly—conserving fuel. When you step off the brake, the engine restarts instantly—lag free.

*A process called regenerative braking, which transforms your vehicle’s forward momentum into energy when you slow or come to a stop.

*A state-of-the-art lithium-ion battery pack stored in the trunk, which uses the energy created via regenerative braking to power the radio, climate control, and other accessories whenever the engine operates in auto stop mode.

In fact, the 2012 LaCrosse gets better highway fuel economy than the Lexus HS and Infinity M Hybrid.

It’s the combination of simple ideas and innovative technology that helps Buick make 36 MPG HWY a reality on the road. That means you can enjoy more time driving and fewer stops at the pump.



The Power Flow Display shows you everything Buick eAssist Technology does to improve your vehicle’s fuel efficiency as it happens. See when your battery is charging, when your engine is in start/stop mode, or when the electric motor is giving you a boost. All you need to do is keep driving—eAssist will do the rest.

Ever wonder how efficient your driving is? Get instant feedback on how economical your time on the road is with the ECO Gauge located in your vehicle’s instrument cluster. The ECO Gauge responds to the way you drive and lets you know the effectiveness of your acceleration and braking. Imagine that—a car that not only makes you look smarter, but also makes you drive smarter.

The 2012 Buick LaCrosse with eAssist Technology brings innovative fuel economy together with world-class luxury to create a rewarding driving experience.

It is also now available at Peterson Chevrolet Buick Cadillac in Boise Id.
