At Briggs Buick GMC - the leading Buick dealer in Manhattan, KS - they are excited about all the great new technology coming from Buick, especially the new eAssist tech on the 2012 Buick LaCrosse.

Thanks to super smart technology in the Buick that doesn’t require compromising the ride, performance or costs that typically accompany hybrids, engineers have been able to boost the fuel economy of the LaCrosse quite a bit.

“The eAssist system integrates regenerative braking with the latest lithium-ion battery technology, for significant fuel-efficiency gains customers will enjoy,” said Steve Poulos, global chief engineer of the eAssist system.

“Providing electric boost to the powertrain system during heavy acceleration and grade driving helps the transmission operate more efficiently. The engine start-stop and fuel shut-off during deceleration features add to the fuel savings.”

While in fuel shut-off mode, the motor-generator unit continues to spin with the engine to provide immediate (smooth) take-off power when the gas pedal is pushed down. As the vehicle comes to a stop, the motor-generator unit spins the engine and brings it to a smooth stop – properly positioned for a smooth restart.

“The battery system is designed to provide power assistance to the internal combustion engine, rather than storing energy for all-electric propulsion,” said Poulos. “It’s really an extension of the conventional internal combustion engine, not a replacement for it.”

An auxiliary, electric-driven transmission oil pump has been added to the 6T40, which keeps the transmission fluid flowing when the engine shuts down at a stop. This helps keep the transmission ready to perform when the driver accelerates, for a seamless driving experience.

“It’s a very integrated powertrain system, with no compromises in driving performance, shift quality or ride and handling,” said Daryl Wilson, LaCrosse lead development engineer. “We believe this combination points to the future of vehicles powered primarily by an internal combustion engine.”
