Full-size luxury sedans are typically guilty pleasures since they can be coddling, comfort machines or all-out speed freaks. One thing they haven't been is fuel efficient... until now. Making its debut at the 2010 LA Auto Show is the 2012 Buick LaCrosse for sale in Berlin. This now contains eAssist technology which we are going to showcase in this blog.
Power for the LaCrosse eAssist is provided by a 2.4-liter four-cylinder gasoline engine with direct-injection. It gains an efficiency boost through the addition of a 115V lithium-ion battery pack, which allows the fuel system to take a nap during certain conditions. These two power systems working together, along with the six-speed automatic transmission, allow the Buick LaCrosse eAssist to achieve 25 miles per gallon in the city and 37 mpg on the highway - a 25% percent improvement compared to the 2.4-liter flying solo. Consider this the reinvention of GM's long lost mild hybrid system.
The eAssist system becomes the standard powertrain on LaCrosse starting next summer. The system uses a state-of-the-art lithium-ion battery system and electric motor-generator to enable regenerative braking capability to improve LaCrosse fuel economy by an estimated 25 percent.
"The LaCrosse with eAssist technology is the latest example of how this successful car - with sales up more than 200 percent for the year - is shaking up the segment and reinventing Buick," said John Schwegman, vice president of Buick marketing. "It is the smart choice for those who want great fuel economy and performance in a luxury vehicle, with excellent value - the LaCrosse with eAssist will cost thousands less than competitors with similar technologies."
Mated to a 2.4L Ecotec direct injection four-cylinder engine and next-generation six-speed automatic transmission, the eAssist system uses power stored in the battery to provide needed electrical boost in various driving scenarios, optimizing engine and transmission operation. An advanced 115V lithium-ion battery and latest-generation 15-kW motor-generator unit help increase fuel economy through:
- Regenerative braking, which provides up to 15 kW of electricity to charge the battery
- Providing up to 11 kW (15 hp) of electric power assistance during acceleration
- Automatic engine shut-off when the vehicle is stopped
- Aggressive fuel cut-off during deceleration down to zero vehicle speed, enabled by the torque smoothing provided by the motor-generator unit
- Intelligent charge/discharge of the high-voltage battery.
Buick LaCrosse with eAssist technology also features improved underbody aerodynamics and tires optimized for performance and fuel economy, as well as active control of front-end airflow that improves aerodynamics and engine warm-up. Electronically controlled shutters in the lower grille close at higher speeds to push more air over the vehicle, which increases aerodynamic efficiency to enhance fuel economy. All of these technologies increase the eAssist system's regenerative braking capability, while also improving the vehicle's efficiency while driving.
