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, has a 19 percent increase in city fuel economy 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 powertrain 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. With the introduction of this new standard powertrain, the 2018 LaCrosse starting price will be lowered to $30,490. The 3.6L V-6 will be an available option on select trims.
Other notable updates to the 2018 Buick LaCrosse include expanded availability of AWD and an all-new nine-speed automatic transmission for V-6 models that will provide customers with a smooth and refined shifting experience. By this time next year, five Buick models will offer this advanced transmission. In response to customer demand, Buick's intelligent AWD with active twin clutch is now available on the Essence trim level.
In addition, the 2018 LaCrosse will have three new exterior color options: Satin Steel Metallic, Dark Slate Metallic and Red Quartz Tintcoat.
