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.

You need to see this 2009 link which breaks down the foreign vehicles made in each state and % of parts that are North American made (US-Canada). Spot checking the site I don't see a single one under 50% other than BMW (30%) and most average around 65% US-Canadian content. Compare that with, say, the Corvette which is 70% or the Jeep Wrangler which is 56%. We need to look in our own backyards before flinging around percentages of foreign cars.

Why "US- Canadian " content I wonder? Where is US only which is what relevant to this discussion? Jobs going either to China or Canada are the same to me - they are lost.

Good question actually. The US and Canada have had tight partnerships in the automotive industry for decades. It's nothing new. The US automotive industry has referenced "North America" produced and included Canada as long as I can remember.

In any event, I'd rather be in a partnership wit Canada over China or Mexico any day.

Have you read the Act itself? What constitutes a domestic part is clear as mud. The labeling act is quite easy for the manufacturers to manipulate, its pathetic at best.

As to Canada and the US they have been cooperating on cars for almost a hundred years.

As to GM they appear to be a yes man for the the current administration and that is enough of a standard for me to say they jump on command when told to do so. Appearances of an act, regardless of the facts, is enough to get military members punished. Congress wrote that law BTW. So that is where I get my standard.

To mix Government and private sector like that leads to all kinds of wonderful, unaccountable to the people, organizations like Fanny, Freddy, Amtrak... What a great track record. Look back in history at any Gov/Private business marriages and see all the wonderful outcomes.
