Jeep Grand Cherokee Diesel

[azjack]

Adding to post #9, our Jeep is two wheel drive Laredo with standard suspension that was a result of Mercedes owning a major portion of Chrysler/Jeep, no air or adjustments, keeping it simple. When traveling we have +/- 380# tongue wt., two fold-up bicycles and at times a generator in the back of the Jeep and without the WDH the Jeep does not drop the rear but an inch or so and the hitch brings that back up. When we bought the 2011 GC it was a brand new item for up to half price of some other TV's we were looking at and it could be repaired at many dealers if needed. I read that Mercedes gets credit for the suspension, Dodge for the engine and Fiat for the fit and finish, a great combination I believe and I have never worked for an auto company.

Keep in mind the added maintenance costs associated with diesels. The oil changes typically are more , fuel filters, and def fluid that most have now. There is also the increase in repair costs, the parts are a lot more money. The thought that the engines last longer is only really true in the heavy truck world . A gasoline engine will last just as long if maintained properly in a light duty application .

In the long term it is pretty much a wash out between the smaller CID diesel and the larger CID modern gas engines with fuel injection, double overhead cam, and variable valve timing. Disabling cylinders is not that effective. Nor are the HEMIspheric domed pistons that once were more effective with engines that used carburetors for fuel delivery.

The other item to keep in mind is the full air suspension, ask any range rover owner about that system and they will not be smiling. Very un-reliable and very expensive to fix. On another point , the variable valve timing is where the biggest gains are for power and fuel economy. The disabling of cylinders is in my opinion a sales gimmick , the gains are minimal. Variable valve timing lets you have your cake and eat it too.

^^Toyota has had their issues too with air suspension

[Brian B-P]

Air suspension certainly adds parts, and therefore risk of failure and repair expense. Modern vehicles are vastly more complex than even a couple of decades ago, to provide the features and functions we want, and maintenance cost is part of the deal.

Range Rovers are a product of Land Rover, which was originally British, then were taken over by Germans, then became part of a global company, and now is owned by a company in India. None of this history suggest to me a good chance of high reliability or low service cost.

On the other hand, air suspension is almost universal in heavy on-the-road trucks and large buses. I haven't heard of any reliability issue with these vehicles.

Hi: All...Since joining our local transit co. I have blown several tires, air bag susp. units, and several equalizer valves to boot!!!

Update 3: Cummins, Feds Continue Developing I-4 for Nissan Titan - PickupTrucks.com News

[dave macrae]

Holy cow would that ever make a nice tow vehicle for a 5.0 or a 19ft er . With some nice fuel economy

[J Mac]

I didn't see a price.
It's going to be a nice TV but the price isn't posted. Diesels as a rule are more expensive in Canada and so is fuel and diesel mechanics. Sometimes the difference in vehicle price between gas and diesel can be close to 11 grand (as in the Ecodiesel). It would take a lot of fuel savings to even that out. I suppose the bean counters will factor in the truck cost difference against the fuel savings and come out with a pro or con.
That said, this truck may not even be available in Canada.

If it doubles my current mpg it maybe worth it.

[dave macrae]

Gm had been toying around with prootype " baby duramax" for a few years, sadly nothing has come to be as of yet, maybe a competitor coming out with something will kick start the market.

Something we may want to consider is that our vehicles are not part of this equation.
The two Nissan Titans are. The difference in price between the two vehicles, gas vs. diesel, and the MPG saved is the question. Can the fuel savings be recouped over our term with the Nissan Titan?
Judging by Canadian lease terms, the average motorist changes vehicles every four years or so.

[dave macrae]

Are you asuming we are "average"? I don't know if to be offended or flatered.

[escape artist]

Hi: All... I don't know if we're above or below average but I buy cars and trucks with a ten year plan in mind. That means a new car for my wife in 2015...or an electric bike!!! Alf

Alf, I think you fall into the 'or so' category.

Prior to retiring, my rule was a new vehicle every 100,000 miles or 10 years, which ever came first. Since my 2010 RAV4 has 66,000 miles on it, I may have to revisit that idea!
