2012 Buick electric vehicles ™ introduces a new technology that increases fuel consumption fuel economy by 25 percent compared with the LaCrosse engine four-cylinder/six-speed 2011. EAssist Technology offers world-class fuel economy of 37 mpg on the highway, without losing the luxury, performance and the expected value of Buick's flagship sedan.
The system becomes eAssist powertrain is standard on the LaCrosse from next summer. The system uses state of the art lithium-ion system and electric motor-generator to allow regenerative braking to improve fuel economy 25 percent LaCrosse.

"The LaCrosse eAssist with technology is the latest example of how successful this car - with sales up over 200 percent for the year - throw off the segment by helping to reinvent the Buick," said John Schwegman, vice president of marketing for Buick. "This is a good choice for those who want great fuel economy and performance in a luxury car with excellent value -. The LaCrosse with eAssist cost thousands less than its competitors with similar technologies "
Mated to a 2.4-liter direct injection Ecotec four-cylinder and the next generation six-speed automatic transmission, the system uses the energy stored in the battery to provide electrical stimulation necessary eAssist in different driving scenarios, optimization and performance motor transmission. Avance 115 lithium ion and the latest generation of 15 kW engine-generator fuel economy will help boost the drive through:
• Regenerative braking, which provides up to 15 kW of electricity to charge the battery
• To provide up to 11 kW (15 hp) power assistance during acceleration
• Automatic stop when the vehicle is stopped
• fuel cutoff during deceleration aggressive zero vehicle speed allowed by the smoothness of the torque provided by motor-generator unit
• Intelligent charging / discharging the battery to high voltage.
LaCrosse Buick eAssist with technology is also equipped with underbody aerodynamics improved and optimized for performance tires and fuel economy, and active control of air flow front, which improves aerodynamics and heat engine. Electronically controlled shutters on lower rack near the highest speed to push more air in the vehicle, increasing the aerodynamic efficiency to increase fuel economy. All these systems technology eAssist increased braking capacity, while improving vehicle performance while driving.
"LaCrosse is the first segment of its transmission four-cylinder/six-speed, Strut Hiper before and now looks the way for a new standard for technology eAssist," said Schwegman. "The important thing is, with eAssist LaCrosse is a standard for the transmission-equipped four-cylinder models, and there is no premium cost."
LaCrosse with a pressure gauge on the dash eAssist ECO, which is constantly driving to react, allowing the driver to drive as efficiently as possible. It 'also a hill-help, which captures the brake pressure to help the driver to accelerate more convenient to stop moderate to strong. It does so by reducing the tendency of the vehicle to restore the engine shut down.
Details eAssist.
Although eAssist system to share the same belt-starter-charger design BAS previous assembly, produces more than three times more effective and is much more likely than the previous generation of the BAS.
"This is the system eAssist is more than just the next generation of BAS system. The ability to integrate with the braking technology of lithium-ion battery last creates a system that offers significant fuel efficiency gains that will benefit customers, "said Steve Poulos, chief engineer of the overall system eAssist. "Being able to deliver lifting electric powertrain system under hard acceleration and transmission quality training enables LaCrosse to operate more efficiently, while additional features engine start-stop and fuel shutoff during deceleration added fuel savings. "
EAssist System 115V air-cooled lithium-ion mattresses 2.4l Ecotec four-cylinder is about 11 kW (15 hp) of power assist during acceleration heavy, and 15 kW of regenerative braking. This is comparable to only 2 kW of power and regenerative power of 5 kW watch previous system BAS. Higher power capability allows you to recover more energy during regenerative braking to improve fuel economy.
The system also allows the Ecotec to close the fuel supply in terms of a slowdown, the additional fuel savings. While cut off mode, the motor-generator unit continues to rotate with the engine immediately and provide energy to a good start when the driver presses the accelerator. Then, when the vehicle stops, the motor-generator unit is operating the engine, leading to a smooth stop - well positioned for a graceful restart.
"The battery system is designed to provide assistance to power internal combustion engine, rather than storage of energy for all electric propulsion," said Poulos. "It's really an extension of the conventional combustion engine, not a replacement for her."
The power supply contains eAssist lithium-ion battery, power inverter built in 12V. It is located in a compartment between the rear seat and trunk, and is surprisingly compact and lightweight, weighing only 65 pounds (29 kg). Still allowing access to the trunk by folding rear seats - an attribute not shared with competitors hybrid. The boot is slightly reduced compared to 2011 models with four-cylinder/six-speed propulsion system, but offers 10.9 cubic feet (307 liters) of storage. An electric fan cools the power supply, drawing air from a vent located in the package tray behind the rear seat. The fans are designed to be quiet in the cab.
EAssist electric motor-generator system installed in the engine instead of the shipper, as well as to provide the electric motor assist and activities that generate the motor system through a new belt. The motor-generator is high performance, compact induction motor, which is cooled to enhance performance and efficiency.
The next-generation six-speed transmission.
System works EAssist LaCrosse 2.4l Ecotec four-cylinder direct injection, and the next-generation six-speed automatic transmission combination. In LaCrosse with eAssist, the engine is rated around 180 horsepower (134 kW) and the next generation of Hydra-Matic 6T40 transmission technology, will be held the next level of features designed to improve the efficiency of the power line.
Significant internal changes to the transfer switch and controls the hardware that causes the loss of rotation, improving the response and time-shift. More power offered by the system allows greater eAssist gears to improve efficiency without compromising the steady state acceleration and driveability. The system's ability to offer some help to cruising speed electric, the driver can accelerate gently, or get a slight degree without downshifting the transmission.
Additional electric pump oil is added to the 6T40 transmission, which keeps the transfer of fluid and flows triggered when the engine is shut off at stops. That keeps the transmission ready to run when the driver accelerates, seamless, no-compromise driving experience.
"This is a highly integrated drivetrain without sacrificing the driving performance, quality change, driving and handling," said Daryl Wilson, lead development engineer LaCrosse. "We believe this combination suggests the future of vehicles powered primarily by an internal combustion engine."
