MiscellaneousGreat Article on Fuel-Efficient Diesel Chrysler Vehicles
Posted by mike on 2008/3/24 14:20:00 (3157) reads

One of our readers (thanks, Jason!) passed along this link about how outside of the United States, Chrysler appears to be a leader in fuel-efficiency with its extensive lineup of diesel vehicles - the funny part is that they're all built here in the United States!

Chrysler is uniquely positioned among the Big Three US automakers. Unlike Ford and General Motors, Chrysler is already building a slew of high-MPG diesel-powered vehicles right here in the United States.

Amazing as it may seem in these difficult times, Chrysler is not allowed to sell those cars domestically, due to recently tightened emissions regulations. With the exception of the domestically-available Jeep Grand Cherokee diesel, all of Chryslerís North American manufactured high-MPG diesel-equipped vehicles are being shipped abroad.

Each and every one of Chryslerís European models is available with a diesel engine, with the exception of the Dodge Viper. In fact, a diesel engine can be found under the hood of more than 50% of the vehicles that Chrysler sells in Europe.

All-in-all, a dozen Chrysler, Dodge, and Jeep diesel-engined models are currently available outside of the United States, but are not sold domestically.

Hereís the eye-opener Ö half of those models currently achieve 35 miles per gallon combined.

Thatís 35 MPG Ö right now.

The article is a great read - the fuel efficiency comparison numbers for the various Jeep models is very eye-opening.

 Re: Great Article on Fuel-Efficient Diesel Chrysler Vehicles
Did anyone else find the errors in the Digg article. The main one I saw is that the VM 2.8Lcrd is offered from the factory with 339lb-ft. I went to the Dodge uk, Chrysler UK and Jeep UK dealership web sights and at most the VM 2.8L crd puts out 174hp 302lb-ft for the nitro & wrangler sport 2dr & 4dr with manual. Wrangler limited used the 161hp 295lb-ft. The chrysler grand voyager just has a 161hp 265lb-ft 2.8Lcrd and offers the 3.8L in the uk. I thought 339lb-ft was a little much for a FWD minivan. 265lb-ft would at least give you additional tranny life.
The rest of the specs look right. Other than the few errors, I'm putting that link on my favorites.

Great posts here!

Josephus, you hit the nail on the head!:
By creating exceedingly stringent NOx emissions, the US govt. has all but eliminated the ability to utilize our best truly alternative fuel...

The "Granola Bars" have screwed us up yet again!

The new S15 ULSD diesels "scare" me because once all the pollution control equipment is out of warranty, the owners are stuck footing the bill to replace the NOx reduction gadgets & get our respective "$tate emissions" $tickers each year! Anyone out there want a refillable UREA cartridge leaking in their driveways?

Add that to the INCREASED price (and, in some areas, limited availability) for the new S15 fuel and the PREMIUM price charged for new diesel engines, and their "advantages" quickly wane... Up here in the "Arctic" the biodiesel fuel can be a sticky problem, too...

Diesel produces more soot or smog than gasoline.

Diesel takes more crude oil to produce than gasoline.

Diesel fuel contains between 18 and 30 percent more energy per gallon than gasoline. Diesel technology also offers a greater power density than other fuels, so it packs more power per volume.

Crude Oil yields more diesel per gallon, because gasoline by it's nature is a more highly refined product, and produces more wasted crude by-products.

While it's true older dirty diesels do contribute much more smog than gas engines, the newest clean-diesels are better than their gas counterparts. Especially when running on the latest ultra-low sulfur diesel fuels now at the pumps or BioD.

While most of the low-emissions vehicles get their low-smog ratings from the fact that the Hybrid-Electric package allows it to run on electric batteries. Combining diesel with electric hybrid packs will yield even better results. This is due to the inherent strengths of the diesel engine and it's ability to create torque at low engine speeds, which is ideal for generating electricity. The US Navy and locomotive industries have known this for 50-100 years.

Everyone who has really investigated gasoline and diesel engines understands they each have their strengths and weaknesses. Gas is good for quick acceleration, diesel is good for moving heavy loads.

The real advantages of diesel engines are not the crude oil gains, which although significant do not decrease the US dependency on foreign oil. For me the biggest advantages for the diesel engine are BioDiesel fuels which can be grown right here on the American farm. No longer requiring our soldiers to steal oil from the other side of the world to support our lifestyle.

By creating exceedingly stringent NOx emissions, the US govt. has all but eliminated the ability to utilize our best truly alternative fuel. One that does not compete with humans or livestock for resources (like ethanol).

With modern CVTís and hybrid packages, a smaller cubic inch diesel engine could out perform an equivalent gasoline engine on any sensible measure. Which leads me to wonder, why would someone spread untruths?

So it all depends on what your angle really is, doesnít it?
Do you want to:
Cut fuel costs?
Cut US dependency on foreign oil?
Support American farmers?
Produce less toxic emissions.
Produce less smog.
Produce less refinery waste?
Go as far as possible on a tank of fuel?
Go as fast as possible between stations?
Feed big Oil company profit margins, because youíre a stockholder?

In the end, I know there will always be people who refuse to change their fuels. Thatís fine, I would just make sure youíve got your facts straight and from a reputable source before you go posting stuff on the Internet, lest you discredit yourself.

Yet another example of 'Yo Gubbamint" working for you. I guess they have to save the diesel supply for The Union Pacific R.R.(THE largest domestic user of Diesel fuel, even more than the U.S. Navy, which is second)

Now, I'm not a 'greenie' in any way, but there are 2 chemical procedures that are being moved from the laboratory into an industrial process that will positively affect the fuel we buy for our cars...

The first is a process to convert garbage, and really any organic waste, into a useable diesel fuel...

The second just appeared in Pop. Science this month, and it is a process of converting agricultural waste (corn stalks, sawgrass, etc) into a refinable material, using bacteria.

These processes could provide 50-100% of our domestic fuel needs IFF they are applied on a large enough scale, but will that ever happen? we don't know.

Certainly, 1 Hemp plant can provide more Ethanol than one entire corn stalk (corn and stalk), but the pot-heads would go nuts and ruin that too, and rightfully so, the government would probably not allow it to be grown, even for auto fuel.

What it boils down to is that we have about 50 years of petrol fuel to go before something better comes along...I'm sure we have it, but, with China coming up as an emerging country, i'm sure the U.S.A. doesn't want to 'Grow' their fuel when our sworn economic enemy is still pumping it out of the ground.

With Chiina barely able to feed their own population, I'd bet that the U.S. is betting on developing agri-fuel processes AFTER the wells go dry, so China and other un-friendly countries will be to-too busy fueling their domestic car fleet to wage war, military or economic.

I just wanted to make sure you know I was not flaming YOU. I agree with many of your thoughts, and hope they figure out a way to convert the algae to BioD real soon.

No, not at all...

Excellent post that you wrote, I wrote mine in a hurry, but you hit the nail right on the head...It's 01TJ who seems behind the times...

You are right though, Diesel-Hybrid drivetrains are the way to go.

Transmissions, driveshafts, differentials, U joints have all reached their pinacle, but things like hub mounted motors and the Hybrid Hydraulic Transmission are going to carry the 4x4 into the 21st century, mainly because that is the direction the military is going to...

From a military point of view, lose an engine, or a transmission, and you are retreating...

Lose a hub-mounted motor, and you have 3 left to complete your mission, not to mention slient and cool running.

As far as Algae and Biodiesel, these processes will slowly make their way into our fuel market. I think even the HUMMER H2O concept alluded to the fact that algae would produce hydrogen fuel for use in a fuel cell.
