The eAssist mild hybrid system combines a 2.4-liter direct injection gasoline engine and a 115V lithium-ion battery pack along with a 15 kW generator. The latter charges the battery and offers electric power assistance during heavy acceleration. The eAssist LaCrosse also has an auto stop/start system, with the battery pack powering all of the car’s systems when the vehicle is stopped.
Improved underbody aerodynamics, active grille shutters that close at higher speeds to optimize airflow and low-resistance tires contribute further to fuel saving.
Average consumption is claimed to be 20% lower than that of the conventionally powered version, at 7.2 lt/100 km (32.6 mpg), and drops more than 30% in city driving.
