eAssist

• The 5.3L L83 V-8 engine is mated to a mild hybrid eAssist system in order to deliver uncompromised capability and better fuel economy – up to 13 percent – in city driving.
• The mild hybrid belt alternator-starter (BAS) system with a compact lithium-ion battery is joined with the 5.3L EcoTec L83 V-8 engine and 8-speed automatic transmission.
• Electric Power Boost: the on-board electric motor provides up to 13 horsepower and 44 pound-feet of supplemental power during acceleration and passing. The electric motor also enables the Active Fuel Management (AFM) system on the 5.3L V-8 engine to operate in 4-cylinder mode for longer periods, resulting in additional fuel economy benefits.
• Stop/Start capability: added fuel savings are achieved by seamlessly turning the engine off when stopped at a traffic light or in congested traffic and turning the engine back on when the driver’s foot lifts off the brake pedal.
• Regenerative Braking: by using the on-board electric motor as a generator, the energy recovered while braking is converted to electricity to recharge the onboard battery system.
• Power for the eAssist system is supplied by a 24-cell, air-cooled 0.45 kWh lithium-ion battery pack located under the center console (or front bench seat) that uses the same battery cells as the Chevrolet Malibu Hybrid.
