The Buick Lacrosse expands its technological credentials by adding eAssist light electrification for the 2018 model. The combination of an electric motor with Buick’s latest 2.5L four-cylinder engine delivers quiet, refined and spirited efficient performance backed by the value and customer experience expected of Buick.
This new eAssist system, when coupled with the four-cylinder engine, is expected to have a 16 percent increase in city fuel efficiency compared to the Lacrosse’s advanced V-6 and leverages a compact lithium-ion battery pack to provide select benefits found in fully electric vehicles, such as torque-assisted launch, energy-saving regenerative braking and exceptionally smooth stop/start. It will be the standard power train for the 2018 Lacrosse, which goes on sale this fall.
Compared to previous Buick eAssist executions, this newest iteration is more sophisticated, powerful and compact. With its 9 percent increase in overall torque, drivers get the responsiveness expected from a full-size sedan. In addition, the newest eAssist system is discreetly packaged to maintain the Lacrosse’s fold-down rear seat and ample trunk space.
The new standard 2.5L four-cylinder with eAssist is the perfect complement to the powerful V-6 that launched on the 2017 LaCrosse last September. The 3.6L V-6 will be an available option on select trims and standard on Premium.
Another notable update to the 2018 Buick LaCrosse includes an all-new nine-speed automatic transmission for V-6 models that will provide customers with a smooth and refined shifting experience. Lacrosse will have three new exterior colour options (!) Satin Steel Metallic (2) Dark Slate Metallic (3) Red Quartz Tint coat.
