    [SIZE=3]Bring on the war of words. Audi of America President Johan de Nysschen has said that the Chevy Volt will fail and that anybody who buys the car is an idiot. [/SIZE]
    [SIZE=3]His preference for diesels over electric and plug-in cars is based on his following conclusions:[/SIZE]
    [SIZE=3] [/SIZE]
    [SIZE=3]1. A wholesale shift from gas to electric cars in the US would result in a net increase in carbon dioxide emissions due to the fact that about 70% of American electricity currently comes from coal plants. [/SIZE]
    [SIZE=3]2. Recent advances in diesel technology have resulted in very high mileage cars with extremely low emissions. [/SIZE]
    [SIZE=3]3. Diesels already have the infrastructure needed to provide a fuel supply. Electric cars need to have infrastructure built and completely upgraded. [/SIZE]
    [SIZE=3] [/SIZE]
    [SIZE=3]Also, he noted, the Volt doesn’t deliver a premium luxury experience and, therefore, its eco-lux. price tag ($40,000+) is inexcusable to the average consumer.[/SIZE]

    If you give them the same torque and hp, the diesel will have a fuel consumption advantage, yes. But that's not what the item was claiming. It was claiming gasoline pickups could not serve the same purposes.

    Let's note, here, that those drag racing diesels have fuel economy (in mpg) in the single digits in drag tune.

    Nope. A diesel engine is easier to apply turbocharging to only because the block and internals are already built for high compression. A gasoline engine built to the same specs will take more boost and make more power.

    Part of the reason diesel engines are more expensive to build is because you need to build the internals very strong to withstand the high compression ratios (typically 18:1 to 22:1) compared to gasoline (typically 8:1 to 11:1).

    And remember: "it" is short for "innit".

    Because they don't have to follow emissions regulations.

    Neither do they.

    Because it's more fuel efficient. But I didn't debate that point. And note... it's only now that truckers are being required to meet the stricter emissions requirements passenger cars are required to meet.

    Similar is not the same. Avgas is not diesel.

    Emissions? Nope.

    With the size of the engines and number of kilometers locomotives cover, they can justify the payback on the more expensive engines in the long run. Actually... diesel is a better fuel for large-installation engines, because it can be run at very low rpms.

    Ever do a cruise tour of the Philippines? Wonderful. The fresh sea breeze... surrounded completely by sea... and you'll never get lost. Just follow the tinge of diesel smoke in the sky down the shipping lane to the next port... :hysterical:

    Maybe I should have answered all the armed forces in one post? Note that the Coast Guard's small boats use gasoline engines.

    Same needs as railroads... low-rpms... large installations... no restrictions on size or weight of the engine.

    True.

    And true.

    The one that won't mix with your engine oil and alter its lubricating properties, as biodiesel does? Gasoline causes less oil degradation in automotive engines since it doesn't mix with the engine oil... this is a real and worrying problem with the expensive long-chain synthetic oils needed to keep modern, tight-tolerance engines happy.

    Yup. And all it took was some genius at Audi to realize that the rules covering diesel fuels, which were written before high pressure injectors became commonplace, allowed them to use engines that were 50% larger than gasoline engines, with larger air restrictor plates and variable geometry turbos... The rulebook for LeMans is antiquated, and Audi and Peugeot both exploited these loopholes. If the gasoline cars were allowed the same displacement and restrictors... even without the variable geometry turbos, they would dominate the diesels.

    There are venues where diesel has been able to compete successfully with gasoline on a relatively level playing field... but since I'm playing devil's advocate, it's up to you to find out.

    Depends. I've stalled diesels. It's not all that hard. Newer automotive diesels have a higher powerband than old diesels... and... guess what? They're easier to stall than the old trucks.

    Depends. Old diesels that don't meet modern emissions standards in Europe (which is the leader in diesels) can eat anything. Modern, high-pressure diesel injection systems are only partially compatible with biofuels, and can't take straight vegetable oil unless the oil is filtered down to the 5 micron level... and even then, many modern diesels suffer oil degradation and valve wear when using biodiesel or straight veggie oil. And this isn't theoretical degradation, but actual, empirical data. Some straight veggie oil proponents in the US are warning their customers and fellow SVO users against some of these newer engines.

    Oh... And they won't take bunker oil at all.

    Gasoline engines are funny. With modern electronics systems, it's possible to run a spark-type engine on several different types of fuel... gasoline, e85, CNG, LPG and hydrogen. The only drawback is you can't fit tanks for all of these separate fuel types on one car.

    BS. The electric engine in a gas-electric hybrid possesses lots of rare earths that have high value... and this is assuming the gasoline engine is aluminum... if both the gas engine and the diesel are modern aluminum blocks (and the newest diesels coming from Europe are), then recyclability is the same.

    In a few decades, your junk diesel won't be road legal, anymore. I shudder to think what will happen when my Crosswind engine no longer meets emissions, but c'est la vie.

    Complete hogwash. I don't have to pay anyone to recycle my electric motors. In fact... when I have a burned out electric motor, part of the cost of repair is paid for simply by the scrap value of the wiring. ;)

    So... have you ever had a mechanic tell you that he's cutting 3,000 pesos off the cost of your diesel engine overhaul if you give him the old pistons? Didn't think so.

    I love my diesel, and my next car might be a turbodiesel Focus. (I'm still thinking about it...) But you've got to come up with more convincing arguments to show diesel superiority.
