Buick to launch its next generation BAS hybrid system

It's no doubt impressive when today's compact sedans -- which are loaded down with hundreds of pounds of safety gear and chassis reinforcements not found on vehicles from decades past -- top the 40 mpg mark. However, it's even more impressive when midsize sedans approach that mark as well.

You know about the compact 2011 Chevrolet Cruze and 2011 Hyundai Elantra which can hit 40+ mpg on the highway. Hyundai's 2011 Sonata midsize sedan can achieve 35 mpg on the highway in its base configuration. GM is now flaunting its 2012 LaCrosse which will come standard with eAssist technology (which will provide up to 37 mpg on the highway) and will be priced at roughly $30,000.

“It’s a very integrated powertrain system, with no compromises in driving performance, shift quality or ride and handling,” said Daryl Wilson, LaCrosse lead development engineer. “We believe this combination points to the future of vehicles powered primarily by an internal combustion engine.”

The LaCrosse will be powered by a traditional 2.4-liter direct injection four-cylinder engine which generates 180 hp. The engine is mated to a 6-speed automatic transmission. However, GM also includes its next generation "mild hybrid" system which it calls eAssist. On the LaCrosse, the eAssist electric motor provides an additional 15 hp and 79 pound-feet of torque during acceleration. Other features to improve fuel economy include an engine start/stop function and regenerative braking.

A 115V lithium-ion battery mounted in the trunk powers the electric motor, but it encroaches on cargo-hauling capabilities. Maximum cargo capacity drops from an already lackluster 13.3 cu ft to just 10.9 cu ft.

However, the benefits in fuel economy are huge. EPA ratings jump from 19/30 mpg (city/highway) to an impressive 25/37 mpg. The city rating falls short of Lincoln's MKZ Hybrid which pulls in an impressive 41 mpg, but that vehicle is priced higher at $35,180.

“The eAssist system is more than just the next-generation BAS system. The ability to integrate regenerative braking with the latest lithium-ion battery technology creates a system that delivers significant fuel-efficiency gains that customers will enjoy,” said Steve Poulos, global chief engineer of the eAssist system. “Being able to provide electric boost to the powertrain system during heavy acceleration and grade driving enables the LaCrosse transmission to operate more efficiently, while the added functionality of engine start-stop and fuel shut-off during deceleration provides added fuel savings.” 

Official pricing and availability of the Buick LaCrosse with eAssist should be available closer to its launch later next year.

Geeze Room, you want some more. Okay....

Why the assumption that everyone who is unionized works at Walmart or is poor? That's clearly your elitist attitude taking over.

Because unions have been after Wal Mart for YEARS. As for the second point, show me where I stated that Wal Mart employees are "poor." I worked low wage retail jobs for YEARS while in high school and college.

Somehow, you have this weird idea that people who are not educated or have low-paying jobs have no right to speak up for themselves.

On the contrary. My grandfather had nothing but a 6th grade education and wound up a successful businessman in the plumbing industry. He didn't b!tch about it and what he was dealt with in life.

This whole me, me, me attitude is NOT what this country was founded upon.

Actually you are wrong there. This nation WAS founded on ME ME ME - as in ME get the hell away from the Crown and chained freedom - at government control.

Furthermore, if your "private pension retirement plan goes bust", don't look to help from anybody but yourself.

The beauty (and fallacy) of American freedom is that we have CHOICES to make. I chose to work and better myself. People like you recoil like a snake as if it's a sin or something.

You want me to post tons of situations of private corporations taking advantage of non-unionized workers? There are many.

I know. I left several jobs in my career that were underpaid after I found a BETTER job. It's the American way. Maybe you like the Eastern European way better where everyone has the same amount of income. Well, you'll reap what you sow then.

You had to search for that bogus one you posted (I saw that one on Fox News too.

My link was a CBS affiliate link. See exhibit A and dude laid up in the hospital? Maybe you are confusing that with a Tea Party member who was allegedly beat up by some union goons.

Listen. It's apparent you aren't educated. That's nothing to be ashamed of. Some of the most productive and best people on this planet do not have college degrees. But sitting around whining about what life has dealt you, for whatever reason, is not going to man you up. Nor is blindly party voting for so-called caring politicians in Washington.

I'm done here Room. Good luck and man up, man. And I mean that.
