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. It is the standard powertrain for the 2018 LaCrosse.

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.

The 3.6L has projected 305 horsepower and 268 lb-ft of torque. The 3.6L V-6 is 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. In addition, the 2018 LaCrosse has three new exterior color options: Satin Steel Metallic, Dark Slate Metallic and Red Quartz Tintcoat.

The LaCrosse features a grille design with a large opening distinguished by the return of a three-color -- red, silver and blue -- Buick tri-shield insignia, accented by wing-shaped elements set against darkened waterfall grille bars.

Longer, lower and wider than the previous generation, the LaCrosse is built on a stronger yet lighter structure. It is about 300 pounds lighter, which contribute to greater efficiency and more responsive handling.

The LaCrosse's interior is designed to offer an open and inviting space for passengers -- one that is relaxing, luxurious and well-connected. Sculpturally beautiful form and premium materials complement technologies developed for effortless interfacing.
