From this fall Buick is expanding its staggering Regal range with the addition of a new, ultra efficient member, the 2012 Buick Regal with eAssist fuel-saving technology. Offering improvement in the overall fuel economy by 25 percent over the 2011 four-cylinder/six-speed Regal powertrain, the all-new eAssist-based ride estimates fuel economy of 26 mpg city and 37 mpg on the highway.

The 2012 Regal with eAssist is the second ride by Buick that benefits from the state-of-the-art eAssist fuel-saving technology after the 2012 LaCrosse. The system utilizes a battery system, electric induction motor-generator and regenerative braking capability, which incredibly improve the fuel economy. Its fuel economy tops competitors such as the Acura TSX, rated at 22 mpg city and 31 mpg highway.

Tony DiSalle, vice president of Buick marketing shared: "Buick's eAssist technology means customers don't have to trade a premium driving experience for efficiency. We believe Regal and LaCrosse with eAssist provide more logical and affordable choices, compared to other hybrid midsize and full-size luxury sedans."

The newly-packed model with eAssist will join Regal's expanding line-up that already includes 2.4L and 2.0L Turbo (with manual transmission) models, as well as the upcoming Regal GS. Among the highlights of the 2012 Regal with eAssist will be:

  • Lightweight 17-inch alloy wheels and tires with lower rolling resistance
  • A driver-selectable, fuel economy-optimizing mode for the air conditioning system, which enables more frequent and longer-duration engine stop periods
  • An ECO gauge on the instrument panel that continuously responds to driving behavior, enabling the driver to drive with greater efficiency
  • 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.
