Buick Charges 2018 LaCrosse With eAssist Battery

Buick's full size flagship sedan will soon be offered with GM's second attempt at a mild hybrid. The 2018 LaCrosse with eAssist will feature a 2.5-liter Ecotec inline-4 from a Chevrolet Impala paired with an 84V 24-cell 0.45 kWh lithium-ion battery pack and electric motor. The motor itself replaces the alternator as it's capable of performing generator duties for battery recharge including regenerative braking.

Moving around in stop-and-go traffic is where the LaCrosse eAssist works to its strengths as its 2.5-liter Ecotec engine is equipped with start-stop technology while operating in partnership with the electric motor for added torque delivery when pulling from a standstill. Chevrolet says the LaCrosse with eAssist has 19% increased fuel economy over the 3.6-liter V-6 model and 9% more torque over the first generation eAssist system. The LaCrosse eAssist makes 194 hp and 191 lb-ft of torque not including the electric motor (figures yet to be released).

Additionally, Buick has refined the packaging for the batteries so as not to disturb the trunk space and rear-folding seats. The first generation eAssist, launched in 2012, compromised on its gas tank capacity and spare tire space so you can expect the same compromises again. All Buick eAssist models come with improved underbody aerodynamics, 9-speed transmission, and front wheel drive. Stated MSRP for the eAssist is $30,490 making it the lowest priced trim for the LaCrosse. 3.6-liter V-6 models start at $32,065 available in FWD or AWD.

2018 Buick LaCrosse eAssist models will go on sale fall, 2017.
