eAssist technology uses a variety of technological advances and body enhancements to deliver fuel efficiency without sacrificing passenger comfort. eAssist uses a state-of-the art 115V lithium-ion battery system and latest generation 15-kW electric motor-generator to enable regenerative braking, which takes place anytime the driver is off the throttle. Regenerative braking provides up to 15 kW of electricity to charge the battery to power all of the vehicle's electrical systems with recaptured energy instead of fuel. It also uses power stored in the battery to provide 15 hp of electric power assistance in various driving scenarios.
Other enhancements include underbody aerodynamics, wheels and tires optimized for performance and fuel efficiency, and electronically controlled shutters in the lower grille.
An ECO gauge on the instrument panel helps the driver attain maximum efficiency.
eAssist is available on the 2012 Buick Regal , the 2012 Buick LaCrosse and the 2013 Malibu Eco.1
eAssist technology uses a variety of new technology to deliver excellent fuel efficiency without sacrificing performance. eAssist uses both Stop-Start engine capability and a state-of-the art 115V lithium-ion battery to power a 15-kW electric motor-generator. In certain conditions when the vehicle is stopped the engine will stop running to save fuel. All vehicle functions for steering, radio, and interior. When the brake pedal is released the engine restarts seamlessly and the vehicle accelerates smoothly. Under hard acceleration or when at cruising speed the eAssist system can engage the electric motor-generator to help accelerate the vehicle using the power stored in the 115V lithium-ion battery mounted in the trunk. Using battery power for 15 horse power for additional acceleration and helps keep engine rpm's low and assists in getting great highway fuel economy. The lithium-ion battery is recharged through regenerative braking, that takes place anytime the driver is coasting or stopping by using the generator-motor to send power back to the battery.
Other eAssist enhancements include underbody aerodynamics, wheels and tires optimized for performance and fuel efficiency, and electronically controlled shutters in the lower grille.
