The Chevy Volt is a Joke (But I’m Not Laughing…. Much)

March 7th, 2011 1 comment

GM boosters like Marcy Wheeler love the Volt. They also like to compare it favorably to a Prius, as seen in that article.

Which of course means that they’re morons.

Yes, the Volt has finally made, in a very limited fashion, its real world debut. The results? Somewhere between ‘pathetic’ and ‘utterly hilarious’. More on that after an introduction.

Let’s start with the obvious: the Volt is a dirty, dirty car, not a green one.

There are a few things about plug-in hybrids that should be explained before any discussion of their merits. Number one is that the US generates the preponderance of its energy through burning coal. Although newer coal plants are much, much cleaner than old ones, there is simply no such thing as ‘clean’ coal. At all. Ever. It’s a fantasy.

What we don’t get from coal, we mostly get from natural gas and nuclear power. Nukes wouldn’t be so bad, if the US had a competent regulatory environment and adults running the show to deal with the waste issue. Nukes are, after all, basically carbon-free in emissions terms. The waste from fission plants is a real pain, however, and as yet we have no coherent national plan to deal with it, so it just piles up in random collections, waiting for, someday, Yucca Mountain to open, or some other site to stash it.

Not that this stops us from using the power plants in the meantime, because we’re idiots.

So, firstly, plug-in hybrids get their juice mostly from coal, which is filthy. In fact, it’s so filthy that running a plug-in hybrid on electricity is slightly worse for carbon emissions and the environment than running a Prius on gas.

From this figure, it is clear that the carbon intensity of the generation technology plays a
significant role in the total GHG emissions from PHEVs. In 2010, current coal technologies
result in 28% to 34% lower GHG emissions compared to the conventional vehicle and 1% to
11% higher GHG emissions compared to the hybrid electric vehicle.

(Page 7)

That’s the first way in which your plug-in is worse for the environment than a gas hybrid, but not the only. Plug-ins like the Volt rely on lithium-ion batteries for their energy storage. Really, really big lithium-ion batteries. There’s just one hitch:

Lithium is rare, expensive, and in the future can only be obtained in quantity through strip mining the third world. Bolivia in particular.

Oops.

This is bad for the environment, obviously, and awful for indigenous people. But the real kicker for the US is that it’s terrible politics as well. We’re trading, in essence, Saudi Arabia for Bolivia. That’s a winning strategy.

So a plug-in hybrid like the Volt is, right out of the gate, an awful idea for the environment. It runs on dirty coal juice, mostly, and it uses an extremely rare material extracted from the third world for its batteries.

But what about the performance of a specific bad idea? How does the Volt fare in real world tests?

Not well. First, check out its fuel economy:

It all depends on how you drive. Suppose you have a 20-mile round-trip commute, and you plug in your Volt every night when you get home (a full charge requires as few as 3 hours). Congratulations! Your fuel economy is infinity, because you’ll never run the battery pack down all the way. But if you have a 100-mile commute, you’ll be driving at least 60 miles a day under gasoline power, so you’ll have to refuel on a regular basis. And in an Edmunds fuel economy test of a Volt with its battery depleted, the car returned only 31.4 mpg in mixed driving. That’s far below the typical fuel economy provided by regular hybrid vehicles.

31 miles per gallon. My Prius, which is last generation, gets, in the real world (I’ve verified this myself), up to 48 mpg on gas. It varies a lot by weather and road conditions, but in the very worst, coldest, most slippery winter conditions it still gets 35-36 mpg. On old tires.

So when it runs on electricity, it’s dirtier than a Prius, and when it runs on gas, it’s dirtier than a TON of cars.

But the Volt has even more issues when you talk about winter driving:

CHICAGO It’s a tough week to be the guy who led development of the Chevy Volt’s battery. Consumer Reports says its tests showed the battery’s range is a paltry 23 to 28 miles in cold weather, far below the 40 miles originally promised.

“The financial payback is not there,” said Jake Fisher, a senior automotive engineer at Consumer Reports Auto Test Centre. A hybrid, he said in an interview, would make more sense. (The Volt — which runs as a fully electric plug-in vehicle and switches to gasoline power once that battery is depleted — cost Consumer Reports $48,000 at a dealership before a $7,500 federal tax credit. Toyota’s Prius is about half that price.)

Batteries that are too cold are reluctant to release electrons, and batteries that are too hot don’t live as long. In electric vehicles, that means charging more often. In an extended-range vehicle such as the Volt, that means the vehicle will switch over to gasoline sooner than it would in moderate temperatures.

To deal with this problem, auto manufacturers like GM and Ford sandwich their batteries’ lithium-ion cells with materials that can heat or cool the battery when it is in danger of growing too hot or too cold. But that technology only goes so far.

“When you’re driving in the cold, you want heat. That’s going to shorten your range, no matter what kind of battery you have,” Fisher said.

Ah, GM. Glad you recognize, too late, the inherent physics involved here. Batteries need controlled temperatures.. and cars can’t provide them. Because you use cars outdoors.

Duh.

Any other problems we should know about?

“When you are looking at purely dollars and cents, it doesn’t really make a lot of sense. The Volt isn’t particularly efficient as an electric vehicle, and it’s not particularly good as a gas vehicle either in terms of fuel economy,” David Champion, senior director of Consumer Reports auto testing center, told reporters Monday.

Champion believes a hybrid, such as the less expensive Toyota Prius, may make more sense for some trips.

“If you drive about 70 miles, a Prius will actually get you more miles per gallon than the Volt does,” Champion said.

….

Champion called the five-hour charging period “annoying,” and he criticized the Volt’s heating system.

“You have seat heaters, which keep your body warm, but your feet get cold and your hands get cold,” Champion said.

Well, I guess the frostbite *would* deter Volt owners from driving their cars in conditions that expose its shoddy design.

Like winter.

In summary: the Volt is a car that requires you to strip mine the third world and suck down vast amounts of dirty power so that you can run a car that loses a third to half its electric range in the cold and then guzzles gas at 31 mpg while you lose circulation in your toes.

I’m so thankful there’s a massive $7,500 tax credit to encourage idiots to buy this thing.

Toyota Largely Exonerated; Unintended Acceleration Not Caused by Car Electronics; Mainstream Press Couldn’t Care Less, Nor Liberal Blogosphere

February 8th, 2011 4 comments

It’s been, as they say, a long, strange road, but the results are in from the exhaustive NHTSA/NASA (yes, NASA) study on the Toyota ‘Unintended Acceleration’ problem, and the results are: it basically doesn’t exist:

NASA engineers studied Toyota’s (TM) electronic throttle for 10 months and found “no electronic flaws” that could have made the vehicles accelerate out of control, a report that came out today says. Toyota cheered the review, saying it “should further reinforce confidence in the safety of Toyota and Lexus vehicles.”

NASA and the National Highway Traffic Safety Administration (NHTSA) put Toyota’s cars and trucks through the wringer. They examined 280,000 lines of code for flaws, bombarded vehicles with electromagnetic radiation, as well as testing the cars’ mechanical components.

“NASA found no evidence that a malfunction in electronics caused large unintended accelerations,” said Michael Kirsch, Principal Engineer at the NASA Engineering and Safety Center (NESC).

To be precise; yes, Toyota sold some floor mats that an idiot could let get so tangled up around his/her feet that the brake pedal physically cannot depress to the floor. And yes, they had some pedals that themselves were slightly sticky, and wouldn’t bounce back from being pressed as fast as they should. Neither problem causes, from the car’s perspective, ‘unintended’ acceleration; in the first case, driver error leads to a floorboard too cluttered to depress a brake pedal, and in the second, you *did* intend to accelerate, the pedal didn’t press itself, it just doesn’t unpress fast enough afterward.

About this time last year, the media was awash in literally hysterical reporting about this ‘Unintended Acceleration’ problem. Mainstream outlets like ABC and NBC would report as fact the allegations of paid anti-Toyota hired guns like a Professor who rigged cars to do what he wanted by rewiring them, then claimed it was relevant to cars on the road, or obvious frauds who faked incidents to try and cash in via lawsuits.

At the same time, and to the lefty blogosphere’s eternal shame, people like Marcy Wheeler of Fire Dog Lake were engaged in outright scaremongering, if not race-baiting, against Toyota, alleging fantastic conspiracy theories (completely without evidence, as it turns out, since there was no evidence to be had, per NASA testing):

Witness David W Gilbert, an engineering professor at Southern Illinois University, was able to show that there are some errors in Toyota’s ETCS that do not generate an error code. As a result, in such a case, the car would never enter into failsafe mode.

Now Gilbert immediately informed Toyota of his finding–my best guess is he did so last November. But his finding was not among the things that Exponent tested, starting in December. However, when Toyota learned that Gilbert was testifying (those evil tricksy Democrats added him at the last minute) Exponent did middle of the night tests Monday night and managed to replicate his finding.

Mind you, Toyota consistently misrepresented what Gilbert had found. At first, Lentz said Toyota had not replicated his error, and only later admitted they not only had, but he knew about it. Then they claimed, both politely to the Committee and more rudely to Republicans, that he had hacked into their ECTS and therefore broken it. They consistently avoided discussing the evidence there is a dangerous error in their ECTS error system.

I find this bit really telling. Toyota got this information last year some time. They deliberately did not have their whitewash firm replicate it–though when they learned Gilbert could present his findings in a public forum, they were able to replicate the problem almost as quickly as Gilbert did (three and a half hours). Once again, this is evidence that Toyota has a number of things they are deliberately not looking for.

The advanced brake override system

I still can’t figure out why Toyota is ignoring all this–what is either so expensive or so damaging that they don’t want to admit to the real problem. But there’s a hint in the way they’re dealing with the brake override systems. As Lentz described, all new models will be fitted out with what–per Sean Kane–is an absolutely critical feature for Toyota given its problems with unintended acceleration. And they will retroactively put that feature onto seven of their models.

As it turned out, they weren’t ‘ignoring’ or hiding anything. There was nothing to hide, nothing to ignore, and Gilbert’s incredibly obvious hackery had no real world implications.

Toyota was right, and Marcy Wheeler and the many hysterical and conflicted American-car pushers/boosters in Congress eager to demagogue the issue were wrong. Period. Absolutely, categorically, unambiguously wrong.

I was right, on the other hand, and tried to warn her in particular off the evidence-free scaremongering; needless to say, that didn’t work out.

Now watch them ignore these findings.

Hey Balloon Juice, Obama Fans – Thanks a Ton for This

February 7th, 2011 No comments

Yet another critical flaw in the Exchange based system of ‘health care reform’ pushed by our industry captured President and his idolatrous fanboys(and girls):

THURSDAY, Feb. 3 (HealthDay News) — Under the new Affordable Care Act, the health reform package signed into law by President Barack Obama last March, millions of Americans whose income fluctuates during the year may lose health insurance for periods of time as their eligibility for different programs changes.

The authors of a new study appearing in the February issue of Health Affairs estimated that as many as 28 million U.S. adults might “churn” in and out of health insurance programs during the course of a year, sometimes losing coverage more than once.

“It’s a critical issue,” said Cathy Schoen, senior vice president of The Commonwealth Fund, who was not involved with the study. “You could get a raise or lose a week of work or gain a week, and move in and out of coverage.”

By taking a look at U.S. Census data from the last five years, Sommers and a colleague estimated that in the first six months, 35% of families with incomes below 200% of the poverty level will change eligibility while half (28 million) would have crossed the threshold at least once during the first year.

An estimated one-quarter of beneficiaries will likely have their coverage disrupted by crossing the income dividing line at least twice in one year, and 39% will over the span of two years, the authors added.

Within four years, up to 38% will have their coverage disrupted four times or more, they predicted.

“It would be easier to fine-tune if it was a continuous program,” Schoen said, and it would reduce costs.

Yes, Medicare for all really *would* be better, in that it would stand a snowball’s chance in hell of actually working.

But hey, good job, Balloon Juicers. Now not only have you helped turn us into an official corporatocracy, but millions of people will be constantly losing health coverage, which they probably won’t be able to afford to use anyway, every year.

It’s like the O-bots built a machine to kick people in the teeth, over and over again. Fantastic.
