A friend says that his diesel beetle provides about the same number of miles per dollar as the Prius; the beetle provides fewer miles per gallon, but since diesel currently costs less, miles per dollar are similar. Sounded like an interesting comparison. :idea:
Well this is a hip shot but what about both M.P.G. and $/gl being required on all new cars. Pumps could relay price to the car via bluetooth or other and a minimal computer could provide a display for the driver. I am waiting for my Prius and am playing a game to see how high I can make the continuous m.p.g. calculator go on my present car. I am now averaging 22.6 up from 19.8 per tank. I wonder how much of the milage gains that are made in the Prius and other hybrids are psychological, driven by the continuous display of this data. BTW prior to this the computer had been set to miles to empty! Henry Drygas
Saab and BMW both have diesels in Europe that easily beat the Prius in economy. its a telling statistic that Europe and Japan (two countries that produce almost no oil) can build very efficient automobiles but the US (we are controlled by the oil companies) cannot.
What you are seeing there has more to do with cost of fuel. Fuel overseas is taxed excessively, making it extremetly expensive. If were were paying the same price for fuel here, you can bet that all of those ultra efficient vehicles would be everywhere here. And before you suggest it, NO I would not support increasing fuel taxes.
There was a interesting bit on NPR last week on the economy and gas prices that compared Saudi Arabia to a drug pusher who is aware that if the prices go too high countries will start looking for viable alternatives. That is why they will do their best to lower gas prices here in the US. I sure they have a very good idea as to what our tolerances are. The only way to stop this and get a healthier environment and stop burning oil is to be politically active. We need to get the monkey off our back. The first step is to admit we are hooked.

miles per dollar - let snot forget miles per pound of carbon Diesels are dirtier than hybrids. Also as prices rice the multiplier will help thos with higher mileage rather than cheaper fuel prices. Carbon is nasty and lets try to produce less. Lots-o-diesel is not the answer to a cleaner environment.
Actually Billy, diesels are cleaner than CONVENTIONAL gasoline powered cars. Yes, I'm aware of the NOx and particulate issues with them. They remain the only two weaknesses of diesel engines. HOWEVER, the US is finally supposed to begin selling diesel fuel that is in line with Euro IV specifications overseas in 2006. This means our fuel will finally be compatible with the modern injection, and emissions control systems that will be ruined with the use of our current high sulphur muck. There are also new technologies up and coming into the market to answer to the ever tightening emissions regulations for diesels. As for CO2 emissions, diesels excel here as they simply require less fuel to operate than the comparable gasser. I'm all for diesel vehicles. Let's get 'em over here as quickly as possible. Why? Diesels are the original alternative fuel engine. Diesels can be run on vegetable oil based fuel. Try that in your gasoine engine and then tell me how far you got. On biodiesel, diesels emissions whip any gasser across the board with the exception of NOx emissions. Even these are easily treated with a catalytic convertor. You made specific mention of CO2 emissions. They drop to a net value of zero under biodiesel as long as it's not mixed with fossil fuel. Right now, a viable fuel is literally being dumped into the trash. Recyclling waste vegetable oil from all of those resturaunts would be another step towards pulling the plug on the arabs umbillical chord. Since transesterification of biodiesel results in soap as a byproduct, the maker can also corner the market in natural, biodegradable, industrial degreasers as well.
the new european diesels are cleaner than regular gas guzzlers and with diesels that get 50% GREATER fuel economy than a Prius, you cannot deny that they would help out the environment quite a bit. Peugeot has a 7 passenger mini van that get 43 mpg!! here is an article from 2 years ago about an Opel that gets 113 mpg! http://www.auto-report.net/index.html?Fiat...diesel2003.html granted its a high performance prototype with the carbon fiber body etc...but imagine a production car with half the performance. it would still put up impressive numbers. If you are interested in how the european diesels can put up such huge numbers, Popular Science has a pretty imformative article on the subject. http://www.popsci.com/popsci/auto/article/...,198235,00.html
There was a diesel Beetle way back in 1951. See http://www.geocities.com/motorcity/downs/9...sel/diesel.html for an interesting article. However, the Beetle is no substitute for a Prius. Not many good Beetle reviews at http://www.carsurvey.org/model_Volkswagen_Beetle.html . Anyway, diesel may be an option, but isn't it not allowed in California? Why?
Diesel costs more than gas here Where we live (Pacific Northwest), diesel costs about a dime a gallon more than regular gas. It's all a question of how different fuels are allocated in different parts of the country.
does it? i live in the Pacific Northwest and to be honest with you, 1) i never paid that much attention to the cost of diesel and 2) not all stations sell it here.
The Imperial gallon as used in Europe is a larger quantity than the US gallon. I don't remember by how much.
In Puerto Rico, diesel currently costs about 25 cents less per gallon than regular gasoline. Over the years I have seen the price of diesel fluctuate up to 2 cents more than regular gas.
Diesels may not be as clean as thought "Despite Lower Carbon Dioxide Emissions, Diesel Cars May Promote More Global Warming than Gasoline Cars" according to an American Geophysical Union/Stanford University/National Science Foundation Joint Release http://www.agu.org/sci_soc/prrl/prrl0233.html
Diesel in California Anyway, diesel may be an option, but isn't it not allowed in California? Why?[/quote] Actually diesel IS allowed in California! It's quite expensive here, about the cost of premium gas. We have a formula that's quite clean burning, I'm told and that's the reason for the price. Jeemz
<div class='quotetop'>QUOTE(\"Wolfman\")</div> Wolfman, I think you mean England that uses the Imperial gallon. Everywhere else uses the liter. In fact, England may be on the metric scale now that they're part of the E.U. Jeemz
An almost zero emisson Prius in comparison with a diesel VW Golf is a no brainer IMO. The cost of Diesel fuel in Southeastern Pennsylvania has been much higher than Gas until recently. Why? Who knows. Diesel is dirty. It is not as available as gas. It comes from OIL!! We have to get to a place of intellegent consumption at some point here. What are we leaving our children? Stop the polluting, atmosphere warming dino cars. ZERO EMMISION!!!!!!!!!!!!!
I see your point, but the Prius is not going to make a significant difference in reducing global contamination and greenhouse gas concentration in the atmosphere; there will always be too few of them. Miles per gallon and miles per dollar are important parameters for many people. Note also that gasoline, like diesel, is derived from oil, and that contaminants do come out of the Prius muffler; zero emission does not exist.
