GM Diesel Hybrid: Opel Astra

Boy, I really missed this announcement. Then again, I’m not sure anyone else saw it either. Back in January 2005, GM said it was working on an exciting new hybrid-diesel platform:

With fuel consumption below 4-liters/100km (MVEG mix), the Astra Diesel Hybrid is projected to be 25 percent more fuel-efficient than comparable diesel models.

[…]

The two-mode full hybrid technology can provide a significant reduction in fuel consumption helping to meet ever-stringent carbon-dioxide emission targets. Its scalability enables the technology to be applied to markets around the world.

1.7L CDTI with 92-kw/125-hp and 280-Nm/206 lb-ft of torque; with maintenance-free particulate filter

And since then, nada. No news on this concept car. Instead, in January 2006, GM announced a new fashion concept: the hybrid Tahoe. It is like ordering a low-fat BigMac.

The front of the Chevrolet Tahoe Two-mode Hybrid has been lowered 10 mm compared to the conventional Tahoe, which provides additional aerodynamic benefits as well as a smoother and sleeker appearance.

Lowriders are really just guys trying to get a few extra mpg out of their classic Cadillacs and Buicks, right? Reminds me of the Range Rover’s variable height said to increase mpg from 8 to 10 when used to lower the flat-boxy SUV at highway speeds. Hey, every little bit counts, even though they marketed it as a comfort, safety and off-roading stability feature (would you buy a Range Rover for any other reason?). Sorry, I digress:

“This truly looks like a special vehicle,� said [Design Manager David] Smith. “It is packed with details, and every one of them serves a function.�

Looking good is a function, right? Especially to the Design Manager. The function of all that chrome is…

There’s no mistaking this truck for anything other than a hybrid: Badging appears on the C-pillar, on the rear liftgate and on the hitch cover.

Of course. A giant SUV is so clearly a hybrid vehicle that GM decided they would paste big colorful badges all over it saying “Don’t hate us for our high-margin SUV, it’s a hybrid”.

Other aerodynamic refinements include sharpening of the D-pillar rearward, including the taillamps, a CHMSL appliqué detail spoiler over the rear hatch and a closeout panel under the back of the vehicle to facilitate airflow.

Lightweight, aero-efficient wheels with the lowest rolling-resistance tires available for full-size trucks further trim fuel use, and are complemented with a tuned ride to provide the ride and handling performance and attention to detail that customers expect from a totally integrated vehicle.

Ah, now I get it. They’re trying to make it *cool* and *hip* to be hybrid. Cool and hip means driving a Tahoe, thus they were pushed into this decision by the consumers. Maybe they will find some well-dressed androgenous actors to drive the new Tahoe in advertisements. Ok, bad joke. But the fact that SUVs are high-margin does not excuse the fact that the smaller cars are really more efficient right now, especially the smaller hybrid-diesel.

Perhaps instead of this exercise in finding new shades of lipstick for a pig, some GM marketing muscle could be put into technology developments that could put GM back on the map.

I mean, just for perspective, compare the above “wowy, zowy” super cool Tahoe press release language with the ultra-nerd tone for the Astra:

From the outside, the Astra Diesel Hybrid, with its unique panoramic glass roof, doesn’t look much different from a production-version Astra GTC.

Hmmmm. No badges? How uncool. And why isn’t it lowered with chrome wheels? Oh, wait, this is for the european market.

Inside, however, the tachometer in the gauge cluster has been replaced by instruments that provide feedback on the operation of the hybrid propulsion system, such as traction provided by the electric motors, traction from the diesel engine, or both. Another gauge displays the battery’s charge level. Also, a video animation in the graphic information display located in the center console depicts the current propulsion state of the vehicle when it’s driving.

Ah, yes, instruments showing the “current propulsion state”; what every car buyer wants to know when they look for a car.

I have to admit I’m happy that GM is headed towards hybrids, but if only they could try a little harder to get real things really rolling. After all, McDonald’s serves salads now and I hear they are not only tasty but bringing home the bacon:

The world’s largest fast-food chain also Tuesday announced the sale of its new Asian Premium salad, expected to be the company’s largest seller, according to industry experts.

Judge rules for caution on environment

The story is really about preserving endangered US mountain carribou from weekend-warrior snowmobile enthusiasts, but I thought this quote was worth pointing out:

Citing aerial photographs that show snowmobile tracks crisscrossing caribou routes to vital feeding areas, the judge added, “The court chooses to be overprotective rather than under-protective.”

And why not? If you move the snowmobiles to another location, or require them to reduce their pollution (noise and emissions), is there any real difference? Whereas if you do not, the carribou may be gone forever. Seems like the judge made a wise call, in terms of risk. The article goes on to show a little irony:

Snowmobile interests have countered that the herd has shrunk over the decades mostly because of past logging, backcountry skiing and global warming

Global warming, likely to be caused by exhaust. And snowmobiles are one of the worst polluters, each engine putting out the equivalent exhaust of 1,000 cars as I’ve mentioned before. Think about that for a second. Just one hundred snowmobiles would put out 100,000 cars worth of exhaust.

The risk actually identified by the animal experts was that the heavy snowmobiles pack down so much snow that it prevents the caribou from escaping their enemies in deep powder. They also argued that the noise of the unregulated engines disturbs the caribou enough to hurt their feeding and calving. These claims make sense, and were apparently well documented, especially when compared to the “it’s because of global warming, not because of the engines that might be a major contributor to global warming”. Interesting that the snowmobile interests wanted to argue about disturbances caused by backcountry skiing. With logic like that, it is no wonder the judge decided to send the snowmobiles packing. Did the defense present photos of angry-looking ski couples making nasty faces at the caribou? Perhaps they had evidence of the latest ski fashion colors causing a loss of caribou appetite?

California Prop 87 and the new Economy

Some folks in Southern California are starting to try and foment fear and anger over California Prop 87. Sadly, they get it all wrong and use the term “conservative” in vain. In fact, they go so far against the principles of entrepreneurship and individual action that they shamelessly condemn the successful business men who are putting up their own money to fight for 87.

It should be obvious why entrepreneurs would want to remove the partial treatment given to oil companies. The future market is in biofuels and alternative energy, not petroleum. I simply can not understand why the prospect of renewing an ages-old energy source and market (long subdued by the petroleum companies) would make anyone cry “liberal conspiracy”. Of course this situation would not be such a problem if the market had not been broken so badly that the petroleum companies were able to so vigorously attack and blanket alternative fuels.

In terms of the forest for the trees, when every other state has a tax on pumping oil from the earth, why does a California tax suddenly get classified as a disincentive? That’s like saying a company does not have the right to charge for its product because it will create a disincentive related to other companies charging for theirs. Nonsense. This warped perspective is quite telling. Don’t be fooled by people who say that fair treatment of petroleum would be unfair to California. Quite the opposite, Prop 87 removes the unfair incentives given to oil companies and moves the state more in line with a policy against government subsidies to the rich.

And finally, take note that some may try and proclaim that the US government should not be forcing its will on anyone (i.e. tax oil companies) while they also say we are justified to invade foreign countries.

Jatropha

I was reading another misleading article that biofuel will compete with food production, when I noticed a comment about Jatropha. I often wonder why so called “scientists” think that biofuel will keep someone from eating their dinner when the opposite is actually more likely. The Wikipedia explains:

Originating in the Caribbean, the jatropha was spread as a valuable hedge plant to Africa and Asia by Portuguese traders. Currently the tree is widely used as a poverty reduction measure in Tamil Nadu, India, and is being promoted as a very easy to grow biofuel crop in hundreds of projects throughout India and the third world. The rail line between Mumbai and Delhi is planted with Jatropha and the train itself runs on 15-20% biodiesel.

Not sure if there is a direct connection, but if growing a native flowering bush is all that is required to run a train on 15-20%…it’s easy to see why the petroleum companies are so down on biodiesel if even the poor can generate their own source of fuel. Hmmm, can you imagine smaller trains and fueling stations all along the tracks? And I don’t think anyone is thinking about eating the Jatropha so the impact to feedstocks is yet again a big fat 0.

A different comment mentioned “the most promising research is into algae, 50% oil by weight, that could grow in glass frames in desert areas.” Seaweed is a similar bountiful source…the list of natural oils outside the food industry is virtually endless. And that was the whole purpose of Rudolph Diesel’s engine, to provide security to engine owners by offering them the ability to use a decentralized source of fuel.
