GM has announced that all V-8 powered Chevrolet and GMC trucks now feature variable valve timing (VVT) for the 2010 model year. A quick trip back to engineering 101 reminds us that VVT is a piston technology that enables continuous control of valve opening and closing. The end result is better engine breathing, with fewer emissions and improved fuel economy.
VVT has already been available on GM’s small-block 6.0L and 6.2L V-8s. The widely-anticipated addition of VVT to the 4.8L and 5.3L V-8s completes its rollout in the truck small block V-8 engine line. GM made VVT possible by adding a cam phaser to the end of the camshaft that electro-hydraulically controls cam position by taking in information from a sensor and the engine control module.
GM is reporting that when paired with cylinder deactivation (Active Fuel Management) on the 5.3L V-8, VVT helps deliver segment-leading fuel economy in the 2010 GMC Sierra and Chevy Silverado pickups:
The Sierra and Silverado are EPA estimated at 15 mpg city and 22 mpg highway, which is better fuel economy than the less powerful 2010 trucks from Ford and Toyota. (Toyota Tundra 4.6L V-8 EPA estimates 15 mpg city and 20 mpg highway. Ford F-150 292 hp 4.6L V-8 EPA estimates are 14 mpg city and 20 mpg highway.)
This is music to the ears of GM truck fans the world over. Now if we could only get those Colorado and Canyon replacements… like… today – that would be great!
Here is a close-up of the cam phaser assembly used in Chevy and GMC small block V-8s. Shown (from left) is the central valve bolt, target wheel, return spring and the hydraulic unit with sprocket. The engine control module directs the phaser to advance or retard cam timing, depending on driving demands.

In light of recent developments with Saab, what should GM do with Saab?
A few days ago we reported that the Chevrolet Cruze will make its U.S. debut at the upcoming LA Auto Show (on December 2nd). Today we’ve obtained official pictures of the U.S.-spec Cruze along with a few important details:
The doors have triple seals and feature fiberglass “blankets” that serve as water, airflow and noise barriers. The doors are also beta-braced, meaning they close with a solid, precise sound and no resonance.
BETABRACE is a Dow Automotive Systems product that is said to improve distortion resistance, flexural strength, impact resistance, and fatigue. Most importantly, however, is that these benefits can be provided by BETABRACE without the added weight and cost of steel supporting structures. More info about BETABRACE can be found here.
The Cruze will be built at the Lordstown, OH assembly plant and is planned to go on sale during Q3 of 2010.

The automotive industry has been taking huge strides in making its products more environmentally friendly: developing powertrains that operate on alternative energy sources and increasing the amount of recycled components (and materials) in its products.
Moreover, General Motors is taking the sustainability movement to the next step in developing the Chevy Volt, Opel Ampera, and Cadillac Converj electric vehicles. But sometimes it’s the little things that count: take, for example, the roof filler of the all-new Buick LaCrosse that is made of recycled cardboard.
To bring the recycled roof filler to market, GM partnered with global automotive supplier Federal Mogal. If you haven’t yet, check out the short video (above) that describes how the roof filling material came to be in the new LaCrosse.
Most importantly, though, is the need to change perceptions: many believe that recycled materials are in some way inferior to non-recycled content. Lora Herron, Buick Materials engineer, doesn’t think so. The recycled cardboard used to fill the roof of the LaCrosse has very impressive sound-dampening properties that work to make the cabin of the luxurious Buick even quieter on the road. As such, Buick has done something really outstanding here: it increased both – the quality and the recyclable material composition of the LaCrosse; the fact that the roof-filling material in the LaCrosse is recycled means less waste is going into landfills.
It goes without saying that we’re really excited GM is coming up with innovative ideas to make its vehicles more environmentally friendly, all while improving quality.
Of note: some readers who sent us this video have expressed concerns about the long-term durability of the roof filler. Apparently, certain GM models in the 1980′s and early 90′s were prone to sagging roofliners that (obviously) decreased customer satisfaction and resale values. We hope Buick has conducted proper durability testing on the recycled cardboard in the roof of the LaCrosse. We’ve put in an inquiry to The General but haven’t received an answer by the time of publication. As soon as we hear back from GM, we’ll update this post.
GM slipped one past us with their latest press release: in announcing that the 2011 Buick Regal is to be built at the Oshawa Car Assembly Plant starting Q1 2011, The General also unveiled plans to begin production of the Camaro Convertible at the same plant and at the same time.
Last we’ve heard, the Camaro ‘vert was undergoing testing in Australia – that’s when an eagle-eyed enthusiast spotted these pre-production models. The fact that the Zeta-based convertible will only begin production in the first quarter of 2011 means we’ll have to wait at least one year until we can get our hands on the drop-top muscle car.
And for those following the production side of things, the Oshawa plant already builds the hard-top Camaro as well as the Chevrolet Impala. The Chevy Equinox and GMC Terrain compact CUVs are built at the Ingersoll (Ontario, Canada) plant by CAW local 88. Thanks for the tip, Jeff!

The holidays are upon us, the holidays are here – what shall we do now, but sit here and drink beer sell cars… or something like that.
As is common practice in most major organizations, General Motors is looking to clear out its stock of 2009 vehicles. GM is expecting all 2009 models to be cleared out by January of 2010, with Susan Docherty, GM Vice President of sales saying that “All of our efforts will be to sell down our remaining 2009 inventory.” The holiday clearance efforts are already underway and each GM brand gets its own name for a sales event, the details of which can be found on each brand’s website:
Taking a look at the brand graveyard, the last bit of Pontiac and Saturn inventory is set to be sold for good. As of right now, there are about 10,000 Pontiacs and 8,000 Saturns remaining on dealer lots and Docherty said that GM is “…actually winding down those products quicker than we had anticipated.” So if you’re still in the market for a Saturn or Pontiac, we suggest you walk run to your local dealer and pick one up. Who knows, maybe the last set of Saturns and/or Pontiacs will be considered a high-priced antique in half a century (although we doubt it).

There are times when automotive history does not make any sense. Take, for example, General Motors’ decision to discontinue the Pontiac G8 and not bring it back under a different GM badge; or the time during the 1990′s when American automotive giants with deep pockets went on a buying spree in Scandinavia. What I’m talking about, of course, is GM’s purchase of Saab and Ford’s purchase of Volvo about two decades ago. The fact that these acquisitions didn’t make much sense is obvious: what we’re left with today, however, are the results of these poor business decisions.
Volvo has done well under Ford: in a span of ten years, the Gothenburg-based company went from making utilitarian boxes to vehicles that lead the automotive design arena as much in the sheet metal as in the interior. And Ford is using Volvo platforms to underpin many of its own vehicles (Ford Flex, Lincoln MKT, Ford Taurus, Lincoln MKS, as well as many others). On the other hand, GM didn’t’ fare as well with Saab.
Not only did Saab produce some of the most uncompetitive vehicles in the marketplace while under GM’s ownership, it made the brand into somewhat of a laughing stock in the automotive enthusiast community. The 9-5 holds the title of “the car that never gets updated” – it has soldiered on, unchanged, for more than six years; the 9-2 was a Subaru with $5,000 tacked onto its sticker price, leading to the coinage of the term “Saabaru.” And the 9-7 SUV was nothing more than a TrailBlazer with the ignition placed between the front seats. During the time that GM owned Saab, it has managed to alienate the brand’s most loyal owners – those who took pride in driving utilitarian yet sporty hatches – a product GM’s Saab was forbidden from selling because it would encroach on Opel’s territory. Perhaps Autoblog’s Johny Lieberman put it best: “Worse, with Saturn morphing into the American branch of Opel, Saab was the afterthought after the afterthought.”
Most recently, an article in Sweden’s di newspaper reported that GM lost $5,100 on every Saab it sold over the last eight years. How so? It cost GM more money to purchase Saab than the revenue brought in by selling the automaker’s products (read: it didn’t sell many units). GM spent $725 million just to acquire Saab (it did so by making two separate transactions in 1989 and 2000). What it all boils down to is General Motors’ horrible strategy (or lack thereof?) that’s still seen today. What, exactly, was the point of having three luxury brands in Saab, Cadillac, and Buick? The net result was that Saab didn’t get the much-needed research and development funds to replace/update its line-up, Cadillac was (and still is) outsold by luxury imports, and Buick became a brand for grandpa.
And while many GM fans would say that it’s useless going back in time, that GM has changed its ways, and that it’s learned from mistakes made in the 1990′s and early 2000′s, I’m not entirely sold. For instance, how is it that Opel vehicles come to the United States as Buick, yet Opel and Buick brands are both sold in China? And what of Buick in the U.S.? There isn’t a clear brand strategy here either – not with completely different vehicles such as the LaCrosse (a soft roader) and the new Regal (more performance-oriented) under one brand. (I will publish a detailed report about this in the next few weeks).
All this brings us to where we are today: GM is trying to offload Saab without much luck. Koenigsegg recently ended negotiations with The General and rumors are rampant that GM may end up sending the brand to join Saturn, Pontiac, and Oldsmobile in the automotive graveyard. While we believe that the Saab brand has too good of a global brand identity to go away, the future is bleak for the Swedish automaker. Personally, I hope Saab survives the next few years, returns to its roots of building performance-luxury vehicles with a European touch, and flourishes under ownership of an independent automaker. And I have only one thing to say to GM: next time, think before you act with your wallet.

- Guangzhou Auto Show:
- Cadillac updates SLS
- Buick unveils Excelle XT
- Satisfaction Guarantee program status
- Chevy Equinox programmable power liftgate
Back in September, General Motors surprised many when it announced its 60-day Satisfaction Guarantee program that gives customers the ability to drive a GM car and return it if they didn’t like it with absolutely no very little financial burden. The first month of the program saw only one return (count ‘em, folks!) – and that was because the customer traded in his manual-transmission ‘Vette for a slushbox automatic. Today, a little more than two months into the promotion, GM had a total of 193 vehicles returned under the program (out of a total 220,000 sales) .
Now there is a bit of a “number -fudging” going on here, mainly in the way the Satisfaction Guarantee program works: the customer is given a choice – either sign onto the Satisfaction Guarantee program (which gives the customer the ability to return the vehicle) or get a $500 instant discount. So now that we have the basics down, let’s get on with the number-crunching: out of the 220,000 vehicles sold:
So that makes for 193 out of 653 – meaning that (roughly) 30% of vehicles were returned under the program. While that sounds bad on the surface, it’s really not – and here’s why:
That said, some customers who returned their GM vehicle within the 60-day timeframe may have truly been unsatisfied with the purchase. Fortunately, GM is looking to find out what the reasons for returning the vehicles were – so it can learn from those unsatisfied customers. Reuss said that he and other GM executives plan to call customers who returned vehicles under the program and get feedback as to why they made the decision. “This is about the best unfiltered consumer feedback we’ve had,” said Reuss.
The Satisfaction Guarantee program is a very good marketing and promotional tool designed to show consumers that their perceptions of General Motors’ products being inferior in quality are outdated. By calling the 193 customers who returned its products during the promotion, GM will be capitalizing on the opportunity even further by learning the reasons for the returns. That being said, we think GM should extend the program indefinitely just to prove how competitive its products are.
Most recently, the Satisfaction Guarantee program was extended by another 60 days and is now scheduled to end January 4, 2010. Just in case you were wondering: the idea to call customers who returned the vehicles came from GM’s Chairman Ed Whitacre.

Along with the refreshed Cadillac SLS, Buick unveiled a completely new model for the Chinese market at the Guangzshou Auto Show – the Buick Excelle XT. While Buick is calling the XT a 5-door coupe-like sedan, enthusiasts know that this is a rebadged version of the all-new Opel Astra hatch. In fact, there is nothing “coupe like” or “sedan” about it – it’s a hatch whatever way you look at it.
The Excelle XT will include a six-speed automatic transmission with sport-shifting capability, with a choice of three gasoline-sipping four-bangers:
The Excelle XT will go on sale in China sometime in 2010 and will slot in between the Regal and the Excelle (basically a Buick-badged Daewoo Lacetti). Buick North America is expected to get the new Opel Astra sometime in 2011 for the 2012 model year. By that time, we hope a sedan version of the Astra will be released to appeal to the sedan-loving tastes of the U.S.
Check out the Excellle XT gallery below, with the full press release available after the break.
