eASSIST
19
eAssist is a fuel-saving engine technology available on LaCrosse. As the name implies, it uses a compact electric motor/
generator and an advanced lithium-ion battery to assist LaCrosse and its 2.4L DOHC DI four-cylinder gasoline engine by
conserving fuel in certain situations. When LaCrosse brakes to a stop, such as at a red light, eAssist switches its power
source from the gasoline engine to the electric motor. It returns to gas power the instant the driver’s foot leaves the brake
pedal. eAssist also captures and stores energy in the battery as you coast or brake. This energy is used to run accessories
when LaCrosse is stopped with the engine in auto stop mode. When needed, the stored energy also powers the electric
motor, increasing the horsepower and torque of the 2.4L engine for an enviable fuel-consumption rating of 6.5 L/100 km hwy.
