Buick introduces the 2012 Regal with eAssist fuel-saving technology, which improves overall fuel economy by 25 percent over the 2011 four-cylinder/six-speed powertrain.
The 2012 Regal with eAssist joins the 2012 LaCrosse as the second Buick to feature the efficiency-enhancing technology. The system uses a state-of-the-art lithium-ion battery system, electric induction motor-generator and regenerative braking capability to improve fuel economy.
Regal with eAssist offers the range of luxury and convenience packages offered in the other models, along with unique features that include: lightweight 17-inch alloy wheels and tires with lower rolling resistance; a driver-selectable, fuel economy-optimizing mode for the air conditioning system; an ECO gauge on the instrument panel that continuously responds to driving behavior, enabling the driver to drive with greater efficiency; and a powerflow readout in the 7-inch infotainment screen, which shows the flow of energy through the electric assist system, such as battery charging from regeneration and electric power directed to the engine.
The 2012 Regal with eAssist technology features improved underbody aerodynamics and tires optimized for performance and fuel economy. It also features a hill-assist system that captures brake pressure to help the driver more comfortably accelerate from a stop on a moderate or steep grade.
The eAssist system works with Regal's direct injected 2.4L Ecotec four-cylinder and next-generation six-speed automatic powertrain combination. In the Regal with eAssist, the engine is rated at 182 horsepower.
The Regal with eAssist joins an expanding lineup that also includes 2.4L and 2.0L Turbo (with manual transmission) models, as well as the Regal GS.
