Auto Mileage Standards Raised to 35 mpg
Ponca City, We Love You writes "The Senate just passed a bill that will increase auto mileage standards for the first time in three decades. The auto industry's fleet of new cars, sport utility vehicles, pickup trucks and vans will have to average 35 mpg by 2020, a significant increase over the 2008 requirement of 27.5 mpg average. For consumers, the legislation will mean that over the next dozen years auto companies will likely build more diesel-powered SUVs and gas-electric hybrid cars as well as vehicles that can run on 85 percent ethanol. Automakers had vehemently opposed legislation in June that contained the same mileage requirements and Fortune magazine reported that American automakers were starting the miles-per-gallon race far behind Japan and that the new standards could doom US automakers. At the time, Chrysler officially put the cost of meeting the proposed rules at $6,700 per vehicle. The White House announced the President will sign the bill if it comes to his desk."
...so before all us Brits start going on about how our cars perform so much better, you need to multiply US MPG figures by 1.2 to make them equivilant to UK MPG figures, as an Imperial gallon > US gallon.
"Different engines have drastically different amounts of CO2/Gallon emissions"
No they don't. All the carbon in the fuel ends up as carbon, carbon monoxide or carbon dioxide. CO is oxidised to CO2 in the cat, and C will be oxidised in the cats of 2010 diesel engines. C (soot) is not a problem in current gasoline engines.
"They are weakly correlated to be sure"
They are strongly correlated. >>0.9
Stop talking out your arse.
Beyond that, the original poster missed this from the E85 article:
In other words, in a flex-fuel engine you're probably not going to see better emissions since cylinder compression will be set to the fuel with the lowest requirement. In an E85-only engine, you can run a higher compression and burn your fuel more efficiently, thus creating fewer emissions.Oil - proved reserves for the world (billion barrels):

I agree that, even now, we will be seeing an exponential increase in the price of oil. That doesn't diminish the fact that Hubbert's "peak oil" is real, and will occur on a global scale in a matter of decades if not already.

I work in the oil exploration industry.. Oil isn't so easy to find, you know.

You obviously don't know why people in the UK pay so much extra, the government levies a tax on the fuel a "fuel tax" if you will. This fuel tax is then spent on maintaining the roads, public transport and other road related things. Alot of americans argue they have poor public transport, a gradually increased fuel tax would allow your government to improve such services and the quality of your roads. A fuel tax theoretically provides a buffer against rising oil costs as well.
There's the knock on effects as well, my performance motorcycle does 60MPG, my last motorcycle did 110MPG, my parents car does 54MPG on average, my various work mates cars all do 40+MPG. When I needed to get to a neighbouring town 6/7 miles away I had the choice of various buses and a train (it actually took as long to get there by train/bus as it normally does by car.)
The *high* fuel costs in america are already getting people to consider better performing cars why not capatilise on this and use it to improve your infrastructure as well.
In case you aren't aware, gasoline-ethanol blends are subject to a little trick known as the water scam. As you are probably aware, water is not soluble in gasoline - but water is soluble in ethanol, and this ethanol-water mix is partially soluble in gasoline. In short, water can be mixed into gasoline-ethanol blends.. I'm sure you can see where this is going.
As high-ethanol blends such as E85 become more widespread, and fuel prices climb, the opportunity and ability to scam the consumer will multiply. Fortunately, testing for water in gasoline blends is relatively simple, requiring only a simple, inexpensive test kit.
Believe it or not, I actually managed to get an Amoco station shut down (temporarily) in the late 1980s for pulling just this scam. I was in tech school at the time, and noticed that fuel from this station had a way of making my fuel-finicky BMW motorbike run very badly. Did the test, found something like 8-10% water, and called the regulatory authority. Saw the closed sign on the station several days later..
There's a Starman, waiting in the sky / He'd like to come and meet us, but he hasn't got the time.
In the US, is it required to take a slippery driving course to get a drivers' license? Or is it up to the individual states? Anyway, it is mandatory here (in Sweden)since some time ago, and it was quite interesting. You learned what to do and what to not do, as well as what happens if you do the wrong thing (such as turning and braking at the same time).
The US has politicians that don't want to charge more tax and get more money? Wow... we could do with a few of those!
I think the US pays roughly 1/3 the price for petrol that we do in the UK, if they really wanted people to start helping the environment, they'd add tax onto fuel costs, forcing people to get smaller cars, and with the spare tax money they could use it to fund research into better, renewable fuel sources...
But of course, that makes FAR too much sense for any politician to think about, and certainly nobody would vote for wanting to pay more, so it's unlikely to happen
From their October 2007 report:
50kms = half of 100kms so if I get 12l/100km and I only need to drive half of that I'll consume 6l and gas right now is about $1.00/litre so it's an easy $6.
That's the beauty of metric. It's all base-10. Slide a decimal place around and calculations are almost non-existant.
Your rant reminds me of an American gentleman who once scorned the metric system because he knows beyond a shadow of a doubt that 1/4lb of meat is enough for a healthy sandwich so he doesn't have to think at the deli counter. (Strange, since that equates to 113 grams. When working in restaurants I've always made sandwiches with about 80 grams, but I suppose 113 grams or thereabouts would make a healthy sandwich. {shrug} I guess you can insert some sort of American weight stereotype here :)

Shameless plug. Like you weren't expecting it.
