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.

We're still tuned into the SEMA Show, but the news from the fast approaching Los Angeles Auto Show keep dropping in. Now we've learned that General Motors will stage the global reveal of a never-seen-before Cadillac concept study. not surprisingly, details remain slim. It could be a concept for Cadillac's recently confirmed small sedan (often called ATS), which will go up against the BMW 3-Series and Audi A4, or something different altogether. We just don't know. But feel free to speculate in the comments section below.

General Motors has set another sales record in China by selling its 2 millionth vehicle, thus making it the first global automaker to do so in a single year. However, it should be noted that this sales number was achieved by GM and its joint ventures in the country.

In 2007, the Detroit automaker and its partners sold 1,031,974 vehicles in China, rising to 1,826,424 vehicles last year.

According to the ever-enjoyable Wall Street Journal, General Motors may come away from its near-death experience with over $45 Billion in tax breaks on future profits over. Yes, that is Billion with a "B". How exactly did that happen?

Somewhere in the hubbub of GM's catastrophic nosedive into failure, paperwork was put in place to utilize a "tax-loss carry-forward" plan that uses deferred tax assets.

In plain terms, GM gets to put the value of the money the Old GM "lost" (or threw away) prior to and during its bankruptcy on a piece of paper and say it wants to reduce taxable income by that much. This, apparently, can be applied over the next twenty years.

After 84 years, Pontiac, the once proud maker of American icons such as the Trans Am and GTO, breathed its last breath on Monday with the sale of the last remaining new cars. The closure comes one year after General Motors announced that it would terminate the brand as part of a restructuring plan.

Even though production of the last Pontiac, the Vibe, ended in August 2009, there were many new cars left in stock, so a deal was struck with dealers who received official backing to sell them. The agreement ended on Sunday, so Pontiac fans didn't actually get any treats for Halloween, only the confirmation that their favorite manufacturer is really dead.

Chevrolet will use this week's SEMA show to display two new special edition models and two concept versions of its 2011 Camaro. The new production models are the Camaro Synergy Series and XM Accessories Appearance Package, both of which will be available for order in the 2011.

The 2011 Synergy is a follow up to last year's Synergy Green special-edition car, which proved popular enough for Chevy to make the series an annual affair. The 2011 model gets a Cyber Gray exterior finish with an exclusive gray interior featuring red accent stitching throughout, along with a combination of parts that are not available on the normal production models.

The second special edition model is the XM/Accessory Appearance Package, which will be available with the V6 engine only. It comes in an Imperial Blue color sporting several standard goodies such as 21-inch wheels and cold air intake system.

Finally, the two concept models are the Camaro Red Flash and SSX Track Car, each crafted with a blend of original Chevy accessories and new concept parts that could be made available in the near future. Hit the jump for detailed info on specs and a high-res photo gallery.

Vilner, who recently took it upon themselves to redo the interior of a Hennessey SRT600 Grand Cherokee, has now unleashed their interior-modifying skills on the new Camaro. Thank God, because it most definitely needs some fancy-pants stuff like this on the inside in order to take on the Mustang.

For this project, Vilner took a Silver Ice V6 Camaro and then added its own special magic to the seats, dash, ceiling, and all the rest. Instead of the common black plastic and leather found in most Camaros, Vilner's pony car wears "nubuck, aged nappa, and chrome" in its passenger compartment.

There's a redesigned steering wheel with better grips, too. Yeah, that's nice, but I'm still staring at all the leather. Why? Because it looks like a million bucks.

We've known for a while that Cadillac plans to expand its line-up with new models including a smaller than the CTS entry-level sedan, and by doing so, target the likes of the BMW 3-Series and Mercedes C-Class.

Today, General Motors announced the new small Cadillac will be built at the Lansing Grand River assembly plant. The company said it plans to invest $190 million for this purpose, which will result in the creation of 600 jobs and the addition of a second shift.

Hyundai, in another bold move to continue attracting American consumers and impressing the public, will soon be building up to 80% American-sold cars in the US (as long as the Elantra makes as big a splash as the Sonata). That would make the little Korean-that-could as "American" as Ford, GM, and apple pie. While this sounds impressive, the numbers are a bit skewed.

For example, the 80% (or "closer to 70%" if listening to J.D. Power analyst Jeff Schuster) is significant when strictly discussing percentages. If discussing volume, the major US automakers still hold the cards. CNN Money reports that if GM were building 66% of American-sold cars here, the number would triple Hyundai's current volume.

Some presumably drunk people out California way decided to have a little bit too much fun in their recently-rented Corvette and ended up parked in salt water halfway up the car's doors. Thankfully in this day and age everyone has some sort of video recording device within arm's reach, so we have some post-parking-surfing videos below.

Next up on our motor show calendar is the biggest tuning event of 2010, the SEMA gathering in Las Vegas, and like every year, GM will be there with a huge display of vehicles. This time, the General is video-teasing some of the Chevrolet models that will descend on the Las Vegas convention center next month including several Corvettes, Silverados and you guessed it, a boat-load of Camaro builds. Scroll down to watch the clip.

For the Australian car buff, Tom Walkinshaw needs no introduction. Here is the man who founded HSV and was responsible for the epic VL Commodore based HSV SS Group A in late '80s. Though no longer working for Holden, 'Walky' continues to turn out some of the most powerful and ballsiest vehicles Australia has ever seen through the performance company named after him.

At the Australian International Motor Show in Sydney, Walkinshaw Performance took the wraps off its latest model: the WP Series II Supercar. The Holden Commodore Series II SS derived super saloon is fitted with an Edelbrock WP 230 supercharger, boosting power to 617-horsepower (460 kw) and torque to 780 Nm (575 lb ft).

Five years old and still able to turn heads, Holden's EFIJY concept will take pride of place at the first international Motorclassica Concours d'Elegance and Classic Motorshow in Melbourne, Australia later this month.

The stunning [driveable] concept car, which was first shown at the 2005 Sydney Motor Show and features a 489 kw (656 hp) supercharged 6.0-liter V8, Chevrolet Corvette underbody, a 'Soprano Purple' paint job and fan-cooled LED headlamps.

I'm pretty sure most of you outside Australia are wondering a) what the heck a Statesman HQ is and b) why should you care that there's a die-cast model. Well, let me try to provide answers for these two questions:

A) The Statesman HQ was a luxury long-wheelbase model for the masses produced by GM's Holden from 1971 through 1974, and B) Apparently, most readers need not care but for the other four viewers I was referring to in the title, as far as I know, this is the first time that a scale model of the specific car has been built. For more history on the Statesman and details on the scale model, hit the jump.

It appears as if GM has some explaining to do when it comes to the oh-so-important Chevrolet Volt. In layman's terms, various sources are showing up to call out the General about how, specifically, the Volt is motivated.

GM says the gasoline engine doesn't officially move the wheels, and the critics say at some point it does, which if true, means the Volt is a plug-in hybrid (albeit, an advanced one at that) and GM has been lying to us all along.

General Motors today released a new teaser photo of its upcoming 2012 Buick Verano compact sedan together with the news that the vehicle will be built alongside Chevrolet's new small car [we assume GM means the Aveo] at the Orion Assembly Center in Michigan. The Detroit automaker said it plans to invest $145 million to upgrade the factory for this reason.

General Motors said on Thursday it is issuing a voluntary safety recall of 3,996 Cadillac SRX crossovers from the 2010 model year due to a possible damage to the power steering line. According to the company, if the line is damaged, power steering fluid could leak and make its way onto hot engine parts resulting in a fire. GM said it is aware of one such fire in an unattended SRX related to this condition.

Last month, we told you that General Motors' European Opel / Vauxhall division announced the development of a new small car below the Corsa. Now, Autonews is reporting the car, which is codenamed "Junior", will be a funky upscale proposal designed to compete with Fiat's 500 mini in one of the smallest - literally - segments of them all.

General Motor's South Korean Daewoo unit announced today that it will handle initial production of the new Chevrolet Aveo at its local Bupyeong plant in Incheon. The new Aveo will make its debut under the Daewoo brandname in the South Korean market in the first half of 2011 before a global rollout as a Chevrolet.

The numbers are in for the month of September, and for the most part, they're looking good as industry wide deliveries were up 28% over a year ago according to a report from Autonews. Chrysler Group exec should be feeling extra happy as sales soared 61 percent over the same month a year ago, rising from 62,197 to 100,077 units.
