Buick Unveils 2012 LaCrosse with eAssist Mild Hybrid System, Returns 37 mpg Highway

Starting from next summer, all versions of the Buick LaCrosse with the 2.4-liter four-cylinder unit will be fitted with GM's eAssist mild hybrid technology as standard, the automaker announced today. The 2012MY LaCrosse will make its world premiere this week at the Los Angeles Auto Show.

The eAssist system shares the same basic belt-alternator-starter configuration of previous BAS designs, but according to GM, it delivers more than three times the power and is much more capable.

More specifically, the 115V air-cooled lithium-ion battery adds approximately 11 kW (15 horsepower) of electric power assist during heavy acceleration and 15 kW of regenerative braking power, helping the base LaCrosse return 37 mpg (6.36 lt/100 km) on the highway. The system's combine output is rated at approximately 180 horsepower (134 kW).

To further improve fuel efficiency, the 2012MY LaCrosse with the 2.4-liter engine comes with a next-generation six-speed automatic transmission with faster shift times and a start-stop system.

The firm's engineers also developed a few aerodynamic aids as well. Additional panels optimize the airflow under the car, shutters in the lower grille close at high speeds pushing more air over the vehicle, thus increasing aerodynamic efficiency, and the wheels are shod in special tires.

But maybe the best thing about the 2012 Buick LaCrosse with eAssist is that the price will remain the same.

"LaCrosse was the first in its segment with a four-cylinder/six-speed powertrain, the first with HiPer Strut and is now is leading the way with the new standard eAssist technology," said Schwegman. "Importantly, LaCrosse with eAssist is the standard powertrain for four-cylinder-equipped models and there isn't a cost premium."

GM Recalls 2010-2011 Cadillac DTS and Buick Lucerne Over Possible Fire Risk

If you happen to be one of the 13,780 owners of a 2010-2011 Cadillac DTS or Buick Lucerne sedan with a V8 engine, you'll soon receive a recall letter from General Motors. According to the National Highway Traffic Safety Administration [NHTSA], the aforementioned sedan models have alternator cables that can wear through a power steering line causing a fluid leak. The power steering leak could result in a loss of power steering as well as fall onto hot engine parts and cause an engine compartment fire.

Up until now, there have been two reports of fires in late August related to this problem.

To fix this issue, GM said dealers will secure and if necessary, reroute the lines to prevent contact. As expected, the service will be performed free of charge. The Detroit automaker will begin mailing letters to owners of the affected models on November 19.

Buick Teases New GL8 Luxury Minivan for China Market

General Motors has release the first teaser photos of the all-new 2011 Buick GL8, a full size luxury minivan developed exclusively for the China market. The new-generation of the GL8, which will replace the Buick Terraza / Chevy Uplander-based model in China, was previewed last year at the Shanghai Auto Show with the Buick Business hybrid concept model.

As you can see from the pictures we have after the break, the 2011 GL8's exterior styling appears to have remained quite true to the concept model. GM Shanghai did not release specifications, but the production version will most likely be similar in size to the 2009 study that measured 5,278mm (207-in.) in length riding on a 3.198mm (129-in.) wheelbase.

However, whereas the Business concept featured a next-generation Hybrid System, at launch, the new GL8 will be available in China with a choice of a 2.4-liter Ecotec engine or 3.0-liter V6 SIDI unit, as well as a six-speed automatic-manual transmission.

According to GM Shanghai, the GL8 will officially be launched on November 28.

2012 Buick Regal GS with 255HP 2.0-liter Turbo and FWD Unveiled in Production Form

GM has revealed the production version of the 2010 Detroit Auto Show's Buick Regal GS concept but to our disappointment, the automaker has kept the 255HP 2.0-liter turbocharged engine instead of the Opel Insignia OPC's far more potent 2.8-liter twin-scroll turbocharged V6 with 325 ponies. The General's cost-cutters also ditched the OPC's four-wheel drive system as the GS is a front-wheel drive model only.

Buick says with the standard six-speed manual gearbox, the GS will accelerate from 0 to 60mph in less than seven seconds (*estimated). In comparison, the basic $28,200 VW Passat CC 2.0 Turbo with 200HP completes the standard sprint in 6.9 seconds, while the European Opel Insignia OPC in 5.8 seconds.

Later on, Buick will offer the GS with an optional six-speed automatic with Driver Shift Control.

The car rides on standard 19-inch alloy wheels and all-season tire, with 20-inch polished alloy wheels shod in performance tires being optional. Braking power comes from a four-wheel disc brake system featuring Brembo front calipers, while there's also a standard StabiliTrak stability control system with integrated, full-function traction control.

Other than that, the Regal GS features Interactive Drive Control System which allows drivers to customize the suspension settings and steering sensitivity between three modes: standard, sport and GS.

The styling more or less follows in the footsteps of the Insignia OPC with a bespoke aero kit and bumpers, and a raft of interior upgrades such as the leather-wrapped flat-bottom steering wheel, sport seats and unique decorative trim.

The Regal GS goes on sale in the second half of 2011, with pricing to be announced closer to launch. However, being that prices for the 220HP Regal Turbo range from $28,795 to $34,435, we don't expect anything less than a mid-$30k sticker.
