Buick LaCrosse Hybrid  with eAssist

The 2012 Buick LaCrosse Hybrid with eAssist was unveiled and boasts an increased fuel economy by 25 percent, while the eAssist technology ensures a class-leading highway figure of 37 mpg. This system makes use of an electric motor-generator and a state-of-the-art lithium-ion battery, thus enabling regenerative braking capability, which provides up to 15 kW of electricity to charge the battery . The eAssist system is much more capable than the previous-generation BAS system and appears mated to a next-generation six-speed automatic system and a 2.4-liter Ecotec direct injection four-cylinder engine.The engine delivers approximately 180 HP and the added electric power allows a higher gearing without compromising driveability or acceleration performance. It is to be found between the rear seat and the trunk, in a compartment, and includes a 12V power supply, an integrated power inverter and a lithium-ion battery pack. Both motor assist and electric-generating functions are provided by the system's electric motor-generator which was mounted to the engine, replacing the alternator.
Daryl Wilson, LaCrosse lead development engineer, stated that the powertrain system was a very integrated one, offering an improved performance and a high qaulity of handling and ride.
