Buick’s Amazing eAssist™ Fuel-Saving Technology
The price of gas is hot topic as well as trying to find ways to save on gas costs. If getting rid of your gas guzzler is an option for you then you might want to consider a Buick. Buick just recently announced that they are adding the 2012 Buick Regal to its eAssist™ Fuel-Saving Technology lineup, joining the 2012 Buick LaCrosse.
Buick announced the 2012 Regal with eAssist™ fuel-saving technology, which improves overall fuel economy by 25 percent over the 2011 four-cylinder/six-speed powertrain. Estimated fuel economy is 26 mpg city and 37 mpg on the highway (pending EPA certification).
Mated to Regal’s 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 induction 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 induction motor-generator unit
- Intelligent charge/discharge of the high-voltage battery.
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. Its fuel economy tops competitors such as the Acura TSX, rated at 22 mpg city and 31 mpg highway. Regal’s estimated 37 mpg on the highway is 20 percent greater and the TSX doesn’t offer a six-speed automatic transmission, which is standard on the Buick. [GM News]
