2012 Buick Regal gets eAssist Fuel Economy Boost

Reviewers love the Buick Regal, and we named it the 2011 Best Upscale Sedan for the Money for its affordability, performance and quality interior. Still, if you like the Regal, but wish it yielded slightly better fuel economy; you may want to wait till the 2012 model year. “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,” says GM. “Estimated fuel economy is 26 mpg city and 37 mpg on the highway (pending EPA certification).”

The system works like a traditional hybrid in many respects. “Like a traditional hybrid, the battery will help propel the car with up to 11 kilowatts of power from a stopped position and store energy from braking,” writes CNET. “The battery also runs the electrical systems when the car is idle, allowing the gas engine to turn off, and provides a boost during cruising to avoid shifting into a lower gear.”

Those shopping for a larger Buick are in luck, as the new system will be standard on the Buick LaCrosse. “GM first unveiled the new technology in November, announcing it would be standard on the 2012 Buick LaCrosse, and increases the full-size car's gas mileage to 37 mpg highway,” notes the Detroit News. “On the midsize 2012 Regal, however, eAssist will sell as an option.”
