Default Jeep Liberty 2.8L Turbo Diesel, is this a good engine, with a proven track record?

Jeep Liberty 2.8L Turbo Diesel, is this a good engine, with a proven track record?

Does anyone know the history of this engine? Is it designed and built by Mercedes?

Thanks for any info.

I heard that it would be a VM, which is owned by Detroit Diesel, which in turn is owned by DCX. One thing is for sure: it will not be a Mercedes engine.

DChrysler sells the PT-Cruiser in Europe with a great common rail MBenz turbo diesel. But who knows when we will get to see such a thing over here? [img]images/icons/rolleyes.gif[/img]

Here is a review of the PT Cruiser that talks about it's Mercedes sourced Diesel:

http://users.tinyonline.co.uk/sheikh...rPTCruiser.htm

As far as the Liberty goes, Dr. Dieter Zetsche (CEO DCA) has stated that diesels will yield up to a 30% increase in fuel economy. The best fuel economy out of the Liberty with a gas engine is 24 mpg on the highway. So, it looks like DCX expects about 30 mpg out of the Diesel. Personally, it would take at least 35 mpg in a Liberty before I would think of buying one. Oh well, it is a start. Nice to see some more passenger vehicle diesels coming to the US market.

Regards,

Rob

As far as I know it's a Merc engine. So it should be good. The problem is that the liberty is still a chrysler. Watch out for tranny problems. The engine should last forever, providing maintenance is kept up, and it is taken care of. My only gripe is that the 2.8L isn't in the C-class, but in the POS liberty.
<font size="2" face="Verdana, Helvetica, sans-serif">I can't comment on the Liberty but Jeeps in general are good vehicles. We have a '95 Cherokee with inline 6.
With 100K miles we replaced:

Rotors $90.00
Crank position sensor $200.00
Radiator & Water pump $200.00
Oil sending unit $20.00
Total for 100K miles: $510.00

I hope that my TDI can do as well as this.

Very disappointing. I thought the purpose of this exercise was to ENCOURGE the ACCEPTANCE of diesel-powered vehicles in North America. So why not give us a Mercedes engine???? Iím willing to take a chance on a Chrysler, but not without a Mercedes engine. I believe the European Grand Cherokee gets a Mercedes, but itís the North Americans, that need the convincing. Perhaps DaimlerChrysler will reconsider before 2004.

In Europe, the Liberty (called "Cherokee" here) can have two diesel motorisations : a 2,5 CRD and 2,8 l CRD. The former "Grand Cherokee" had a 3,1 l CRD, which has been replaced by a 2.7 l CDI (Mercedes). The were a lot of problems with the old engine. The denomination "CRD" refers to VM engines (:-(( And Mercedes doesn't have any 2,5 or 2,8 diesel engine, so, the two new engines are most probably made by VM. Maybe not the best choice !

Remember, Mercedes does sometimes build a dud diesel, remember the 3.5 Inline 6?

All I'm saying is, don't damn the horse until you've taken a ride.

Mercedes has indeed built a dud or two, but if your counting duds, ChryslerÖah...well, what can I say about Chrysler that hasnít already been said; some of us have been stung before. And given Roadrunner6ís comments about the CRD engines, Iím not at all encouraged.

Chrysler, if youíre listening, why not use the 2.7 CDI in the Liberty? This is a golden opportunity to change the perceptions that North Americans have of diesels and Chryslers.

Your not buying a Chrysler diesel. You are buying a Detroit Diesel engine. Yes, they are owned buy DC but they have been in business for a very long time. They have a good reputation for building diesel engines. If it was stated that this is a new engine designed by Chrysler corp then I might have a different view.

My only beef with it is the article I read about it comming stated 18 city and 29 hwy. I felt that these numbers are a little low and that it should get a little better mileage than that, especially in the city.
