Why is it that one cannot purchase a new diesel automobile in the state of California these days.....but you can buy all the Lincoln Navi-guzzler's & H2 Humm-drinka's you want??????

Because there has not been any push from the Federal government to develop clean-burning diesel motors, availble diesel cars produce more smog-producing components per mile than gasoline cars, even more than giant SUVs. (My wife is renting an Explorer right now, it gets 25mpg mixed, using 4wd frequently in the snow. That's about the same as her 1.8l E30 318is, or my old Volvo 240).

There has been renewed interest in Diesel in California lately, and it's possible that new diesel vehicles that meet the California smog-per-mile quota will appear soon. In the mean time it's easy to find older models, like the Mercedes 190d.

If you get more miles to the gallon than you are polluting less. You get far more diesel out of a barrel of crude than you do gasoline. An old Mercedes diesel is better on the environment than a new electric car. We need to push for more RECYCLED cars- i.e. old cars that are good on gas, courteous, stylish, and enjoyable to drive ;)

I don't disagree with you, but do you have a reference for the amount of diesel vs. the amount of gasoline out of a barrel of crude? Also, what is the stoichiometric air:fuel ratio for diesel? Is it the same as gas, 14.7:1?

One of the major differences is the temperature and pressure of the diesel combustion. The higher diesel compression/temperature combination causes more oxides of nitrogen and other stuff that's difficult to break down with a catalytic converter.

I might buy an old diesel VW or Mercedes one of these days, and run the veggie juice in it. First I'll probably do an electric car project. How about a biodiesel/electric hybrid in a Formula Vee chassis? Could be a fun car for around town.

    BMW Neue Klasse - a birth of a Sports Sedan

    Unveiling of the Neue Klasse Unveiled in 1961, BMW 1500 sedan was a revolutionary concept at the outset of the '60s. No tail fins or chrome fountains. Instead, what you got was understated and elegant, in a modern sense, exciting to drive as nearly any sports car, and yet still comfortable for four.   The elegant little sedan was an instant sensation. In the 1500, BMW not only found the long-term solution to its dire business straits but, more importantly, created an entirely new

    History of the BMW 2002 and the 02 Series

    In 1966, BMW was practically unknown in the US unless you were a touring motorcycle enthusiast or had seen an Isetta given away on a quiz show.  BMW’s sales in the US that year were just 1253 cars.  Then BMW 1600-2 came to America’s shores, tripling US sales to 4564 the following year, boosted by favorable articles in the Buff Books. Car and Driver called it “the best $2500 sedan anywhere.”  Road & Track’s road test was equally enthusiastic.  Then, BMW took a cue from American manufacturers,

    The BMW 2002 Production Run

    BMW 02 series are like the original Volkswagen Beetles in one way (besides both being German classic cars)—throughout their long production, they all essentially look alike—at least to the uninitiated:  small, boxy, rear-wheel drive, two-door sedan.  Aficionados know better.   Not only were there three other body styles—none, unfortunately, exported to the US—but there were some significant visual and mechanical changes over their eleven-year production run.   I’ve extracted t
