Chrysler Introduces New Diesel, E85 Grand Cherokee Models

2007 Jeep Grand Cherokee CRD

Chrysler Group today unveiled the first diesel-powered, full-size sport-utility vehicle (SUV) to be offered in the United States. The 2007 Jeep Grand Cherokee equipped with a 3.0-liter common rail turbo diesel (CRD) engine will arrive in showrooms in the first quarter of 2007.

The company also announced that for 2007, all Jeep Commander and Jeep Grand Cherokee retail and fleet buyers who select the 4.7-liter gasoline engine option will receive flex-fuel vehicles capable of running on E85 fuel.

The new 3.0-liter diesel engine, built by Mercedes-Benz, produces 215 hp (160 kW) of power at 3,800 rpm and 510 Nm of torque at 1,600-2,800 rpm and delivers an estimated fuel economy of 19 miles city and 23 miles highway.

By comparison, the 2006 gasoline-powered 4.7-liter Grand Cherokee, which offers roughly the same range of power and torque, is rated at 15 mpg city, 20 mpg highway. The 3.0-liter CRD engine will be available on the Jeep Grand Cherokee Laredo, Limited and Overland models.

This new Grand Cherokee CRD is not a production version of the BLUETEC Grand Cherokee engineering concept vehicle announced earlier this year. (Earlier post.) A BLUETEC implementation would meet the new federal Tier 2 Bin 5 standards which map to the California standards, thereby allowing the vehicle to be sold in all 50 states.

Although Chrysler will not yet talk about the emissions strategy for the new Grand Cherokee CRD, the vehicle will only be offered in the 45 states that have not adopted the California requirements (i.e. it will come in above Tier 2 Bin 5).

The two areas of major difference between the less stringent EPA Tier 2 Bin 8 (which becomes the uppermost level permissible at the end of 2006) and Bin 5 are in NOx and PM emissions. Getting from Bin 8 to Bin 5 (and CA LEV compliance) requires a 64% further reduction in NOx and a 50% further reduction in PM emissions.

The increasingly tough emissions standards have also claimed another vehicle. Chrysler has ceased production of the Liberty CRD, the first mid-size, diesel-powered SUV in the US. According to a Chrysler spokesperson:

Engineering modifications to the [Liberty CRD] engine as well as other aspects of the vehicle were required for Liberty CRD to comply with the new standards. However, we could not make a credible business case for such an investment, especially for limited production vehicles.

The Liberty CRD was a market test for Chrysler. The Liberty, which features a 2.8-liter engine, exceeded Chrysler’s sales expectations by more than 70%, racking up more than 11,000 units since its introduction.

Volkswagen, the other provider of diesel light-duty vehicles in the US, has also indicated that it would drop its diesel passenger cars from the 2007 model-year line up as it reworks its vehicles to meet the new standards. VW expects to deliver a 50-state Jetta in 2008. (Earlier post.)

That will leave the Mercedes E320 BLUETEC, due to arrive this fall, as the only new diesel passenger vehicle available in all 50 states.

More than 60% of Chrysler Group vehicles sold in Western Europe are diesel-powered. Between 2003 and 2007, Chrysler Group will have tripled the number of diesel offerings outside North America. Of its estimated 20 vehicles available, 12 or more will have the option for a diesel powertrain (up from four in 2003).


fyi CO2

Sounds a bit like GM, eh?
Too little MPG improvement on the 3L diesel.
Too much NOX and PM on the "Grand" cherokee CRD.


How is it that the VW Touareg 4.9 TDI with 310 HP and an extra 1200lbs gets virtually the same mileage??? Seeing as this won't even be sold in California, I don't see how this is even worth it. I'd bet that if they applied the cylinder deactivation to the 4.7 V8, it would be close to the same mileage.....


And a price tag $20000 higher.



It is all about the quality and design of the drivetrain. Of course highway gas mileage is also dependent upon Cd and frontal surface area.

For example:

Hyundai Accent with a 1.6L VVT engine achieves ~106hp in a 2300-2400lb vehicle and gets 35mpg highway ~30-31mpg combined.

Toyota Corolla with a 1.8L VVT engine achieves ~130hp in a 2600-2700lb vehicle and gets 41mpg highway ~35-36mpg combined.

Honda Civic with a 1.8L VVT engine achieves ~140hp in a 2600-2700lb vehicle and gets 38mpg highway ~34-35mpg combined.

(This is all from memory but should be very close to actual figures on the manufacturer's websites given a manual transmission).


The reason is simple. The test doesnt have the car move just the wheels thus the weight of the car doesnt matter nor is fact does so much else. Thats one of many reasons the milage rates given are always off.


Are these fuel tirsty beasts very common in USA? It is wayyyy too thirsty!

Robert Schwartz

Congratulations CARB. Another demon vanquished.


Robert Schwartz, living in Europe where diesels proliferate, I would recommend everyone adopts CARB standards; air quality in car-crowded streets is appallingly low here.



The car doesn't move but the weight of the vehicle is represented in the inertia class of the rolls used to perform the test. Vehicle weight most assuredly does affect emissions and fuel economy. I suggest you read the FTP-75 test procedures....

@JN2 Carb standards affect diesels primarily becuase of tight NOx limitations.

You are not smelling NOx in crowded streets but particulates. That is being sorted by particulate traps in Europe. Even with particulate traps EU diesels still will not pass T2B5 until NOx traps are implemented and then that requires sacrificing some of the fuel econ advantage.

EU emissions regs are biased toward fuel econ whereas US regs are biased toward NOx.

ONLY for passenger cars though, as I've said before this doesn't seem to prevent US manufacturers (and legislators) from churning out smelly full size SUVs/pickups with stone age diesel engines in them. Or their trucks..... Just prevent people from makingmore fuel economical passenger car diesels instead.

One thing's for sure, where passenger car diesel emissions regs in the US are concerned, it's not about clean air that's for sure!

This is a an example of CARB biting itself in the ass. Most diesel (Jeep or otherwise) purchases in the US are for the increased milage, and a significant portion of diesels are bought to be used on very clean biodiesel (except for NOx). A quick tour of the diesel-enthusiast discussion groups will show that the majority of American diesel purchases are by emmission/mileage concious people who recognize a decent, reliable, long lived flex-fuel vehicle that will emitted less poison per mile and fill less junkyards. Shame.

Finally, someone understands why we evil Alabamians must own our beastly heavy duty diesel trucks! Now maybe Dodge will stick that 3.0 in a Dakota so it can have a redeeming factor.


I'm sure it will get better then 24mpg on the highway. My huge 6.6L duramax diesel with 400HP 800LB torque gets about 21 highway (18 average between city/highway). Many report the liberty diesel gets over 30mpg on interstate. This jeep should get close to 30.. time will tell when we get some reviews.


The article should be comparing the 3.0lcrd to the 5.7lhemi, not the 4.7lmagnum, the 376 pound feet of torque
provided by the 3.0l gives 7,600lbs of tow capacity witch would require the HEMI, to post similiar figures.
As to the fuel economy, it could be better, bear in mind that the 3.0l is only being offered with a full time 4x4 system, this creates a good deal more driveline loss.
Compare the HEMI grand cherokee to the HEMI Ram pickup, the results might surprise you considering the size differance.

Jeeps diesel vehicles are sold throughout the world with less horse power and better mileage. It is just the manufacturers impression of what American buyers want.

3.0L diesel Ford Rangers are all over Europe, can I buy one here, nope.

Non tier 2 diesels running biodiesel (NO2 reduced) or WVO will beat all tier 2 vehicle requirements. Why not focus on the fuels?


You`ll be glad to watch this.
