Cars   The combination of an electric motor with four-cylinder engine

The Buick LaCrosse expands its technological credentials by adding eAssist light electrification for the 2018 model.


2018 Buick LaCrosseThe 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.

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.

2018 Buick LaCrosseOther 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.

2018 Buick LaCrosseBuick’s eAssist propulsion system combines a compact electric motor and an advanced 24-cell air-cooled 0.45kWh lithium-ion battery pack with the 2.5L four-cylinder gas engine to enhance efficiency and maintain refined performance. Upper and lower active aero shutters in the front fascia close under certain driving conditions to help maximize aerodynamics and contribute to improved fuel economy. The 86V lithium-ion battery pack, which has been repackaged to be more compact, stores energy captured during regenerative braking. This energy powers the electrical system when the vehicle is in Auto-Stop mode.
