Buick Brings Back eAssist For 2018

Buick has confirmed the brand’s eAssist light electrification system is returning on the 2018 LaCrosse sedan. We confirmed plans of its return back in March after the system showed up on GM’s own internal order guides.

Like the previous eAssist systems, the new one essentially pairs a lithium-ion battery pack and oversized alternator with GM’s 2.5-liter four-cylinder engine. The electrification system provides torque assist at launch, a smooth start/stop system and regenerative braking. The system will serve as the standard powertrain on the 2018 LaCrosse.

Thus far Buick hasn’t confirmed what the EPA fuel economy ratings will be on the new eAssist cars. Instead the company has just stated that it will have a city rating that is 19 percent higher than the LaCrosse V-6. The 2017 LaCrosse V-6 carries a city rating of 21 mpg. Doing the math, that would mean the 2018 LaCrosse eAssist will come in around 26 mpg city, which isn’t far from what the old system was rated.

Thanks to the new standard powertrain, the base price of the 2018 LaCrosse is dropping from $32,990 to $30,490.

In addition to the eAssist system, Buick has also confirmed that the LaCrosse V-6 will upgrade from today’s eight-speed automatic to GM’s new nine-speed automatic transmission. Buick is also expanding availability of all-wheel-drive on the 2018 LaCrosse v-6.

    I guess it is one way to meet the mileage challenge and the price gets lower as well.

    I see no point in this returning other than the lower the base MSRP on the LaCrosse.

    Swap to a 48-volt electrical system and then we'll talk.

    Glad to see the return of this powertrain (in updated form) for the Lacrosse. As much as I love power, I'd rather have the fuel economy, plus the eAssist isn't too slow for the driving I do. Big car, lots of room, and fuel efficient.

    This was the biggest issue with the last Lacrosse eAssist, glad to see they have improved battery packaging. Can't wait to see what this really means for trunk space. No intrusion at all? Or just less?


    There might still be a "step". That's what I have on my MKZ Hybrid but both rear seats can still fold down and there's also a pass through in the middle. That was a big selling point for me since most other hybrids were sealed off or only one side could go down.

    the newest eAssist system is discreetly packaged to maintain the LaCrosse’s fold-down rear seat and ample trunk space.
