The Sierra Club bozo doesn't care about "global warming" or he would be more interested in reducing CO2, which diesels do (especially at 70 mpg).

This guy would rather have a bunch of batteries in landfills than efficient engines.

[Phantom Lord]

This is all a scam. We know the auto companies have 300 mpg engines available but the evil oil company CEOs are paying them billions to not make them available.

If you needed a sarcasm tag I can't help you.

[RobbyS]

Does the Sierra Club have ANY engineers sitting on their councils? I think they believe in magic.

"The auto industry is trying to convince the car-buying public . . . to reject better technology like hybrid cars," said Dan Becker, Washington director of the Sierra Club's Global Warming Program.

No, they're giving them a choice.

Other pollutants are reduced by treating exhaust with a liquid called urea that drivers will need to refill.

Just give us a good target.

My next Jeep will be a liberty crd, common rail diesel. Everything I have heard about them is that are great.

Yep, more proof that the SC's agenda has nothing to do with improving polution, it has everything to do with the destruction of capitalism. Socialist bastar......

Man checking on the various grades of Urea available at neighborhood Urea Station.

This guy would rather have a bunch of batteries in landfills than efficient engines.

You're wrong on that point. They want us to return to the stone age. Themselves excepted of course.

[B Knotts]

Anyhow...I had to cut down the article because it's from WaPo, but that 70 mpg is *combined*.

The highway number is 84 mpg!

Excellent point on the batteries ... heavy metals are serious trouble.

Our family has two (2) 1984 M-B 190D - four door sedans, each with a 72 bhp diesel engine, and five-speed manual transmission. These were purchased new and each has over 480,000 miles on them ... and they consistently get 46+ mpg ... and other than normal maintenance ... not one ounce of trouble ... ever!!!

Now to get M-B to sell their A-Class or B-Class in the US with diesel engines ... a another story.

That 2 door prototype hatchback makes my Prius look positively huge.

Years ago I drove a 300 series turbo diesel, it was truly a great car....think I got about 300,000 miles out of it until an employee of mine wrecked it....oh, and because the car was like a tank, they walked away from the accident unscathed.

Diesel will be making a comeback in this country. My brother publishes the best alternative fuel vehicle magazine in the country, GREEN CAR JOURNAL. He has a long term test care -- a diesel Jetta. It is as quiet as a gasoline engine. This is not your grandaddy's diesel.
