Although Buick completely overhauled the LaCrosse for 2017, it is now bringing big changes to the 2018 model. The 2018 Buick LaCrosse goes on sale this fall with a standard mild hybrid powertrain, lower starting price, and other updates.
Buick will continue to offer a 3.6-liter V-6 that was the sole engine choice on the 2017 LaCrosse. But for 2018, the new standard engine is a 2.5-liter four-cylinder gas engine with eAssist light electrification. This system utilizes a compact electric motor and a 0.45-kilowatt-hour lithium-ion battery pack that stores energy captured from regenerative braking. The eAssist system allows for a 9-percent increase in overall torque. City fuel economy is also 19-percent higher compared to the LaCrosse’s V-6 engine. The current LaCrosse nets 20-21 mpg in the city depending on whether or not you opt for all-wheel drive. Buick offered an eAssist drivetrain as standard on the previous-generation LaCrosse. That car featured a 2.4-liter four-cylinder and a 15-kilowatt motor-generator good for 182 hp and 172 lb-ft of torque. Output figures for the 2018 LaCrosse eAssist have not yet been revealed.
Thanks to the new standard engine, the starting price of the LaCrosse will drop by more than $1,000. The 2017 LaCrosse starts at $32,990.
The V-6 engine, which will be offered on select trim levels, will come paired to a new nine-speed automatic transmission. Buick says the new transmission will spread to five of its models by this time next year. Currently, the LaCrosse is only available with an eight-speed.
Buick is also expanding all-wheel-drive to the mid-level Essence trim. Three new colors—Satin Steel Metallic, Dark Slate Metallic, and Red Quartz Tintcoat—are available for the new model year.
