Re: Diesel Grand Cherokee Coming to US!

The new Jeep CRD does not have the Urea injection, for which I am glad.
The diesel trucks in most countries still do not have a requirement for a exhaust filter.
Mind you I saw a new 320CDI Merc that was smoking like a Trojan the other day, as well as many VW Golf Diesels, so I guess they are not perfect.

Re: Diesel Grand Cherokee Coming to US!

They "smoke like Trojans" when they're going through their cat self-clean mode. As you'd know that happens only periodically.
Can be pretty disconcerting though! lol

Re: Diesel Grand Cherokee Coming to US!

I don't believe you can convert a person to go from Gas to Diesel. It really is a personal choice and right now, the only good sensible choice for any SUV or truck is a Diesel.
Sure, it doesn't have the HP to get you from 0-60 the quickest but that's really not why you buy an SUV or truck.
I say, if you're happy with your Hemi, keep driving it. For the few of us Diesel owners, we never look back 'could've had a V8?'

I think most of the people who criticize them have not driven a new diesel like BMW, Audi, VW, and Mercedes offer. If the VM Motori 3.0 CRD is anything like these, you will need to drive one to believe. I don't really care about 0-60 times in a vehicle like this but the Aussies that have them say they are faster than the Hemi and costs the same. I don't really see the downside. If they bring the 2013 with the 8 speed, I am in.

Nope. Self-cleaning does not mean pouring soot out the exhaust pipe. Self-cleaning means super-heating the Diesel Particulate Filter to atomize the soot. We have 5000 miles on our BMW 335D(iesel) and we never see soot coming out the tailpipes, nor is there any soot IN the tailpipes - it's extremely clean.

For the un-initiated, it can be a little disconcerting during a diesel's self-cleaning process as it smells just like an oven does during the cleaning process.

When I bought my '08 WK I considered the CRD, but it seemed like the Merc engine just wasn't that reliable and would be very expensive to fix. (The BMW diesel will be just as expensive to fix, but seems to be extremely reliable.)

Re: Diesel Grand Cherokee Coming to US!

Those who keep saying, " the diesel would be expensive to fix" make it sound like by buying a diesel you're going to throw a rod or it's going to crack a head. That's an expensive fix for any motor. Fact is, diesels last longer. They don't even break in until ~150K miles, where as gasoline engines break in around 90K or less.

That's also why they have a power train warranty, etc. big trucks are able to pull huge horse trailers for the entire life span and the engine runs fine. Most put 150K within the first several years. Which is more reliable?

You DO know that not ALL the current diesel tech is the same don't you? Some in fact DO smoke like ****ing Trojans. They pour massive amounts of raw fuel down the exhaust to super-heat the catalytic converters and "burn" any deposits off. Other's introduce wee wee to the exhaust over long periods of time.

Regarding the MERC engine, there were reports of expensive repairs to the turbo systems around 70K miles. I think there were also reports of mediocre transmissions, but I could easily be mis-remembering. I wasn't concerned about the engine itself, but the accessories.

The raw fuel is injected into the Diesel Particulate Filter (DPF), not the catalytic converter, during the DPF regeneration process. The fuel burns, heating up the DPF, causing the "deposits" (soot) to atomize/cease to exist. If a DPF didn't totally burn the soot (eliminate smoke), it would serve no useful purpose.

And yes, I'm aware of urea injection to reduce NOX emissions - our 335D has that, too. The two systems are not mutually exclusive.

Re: Diesel Grand Cherokee Coming to US!

i didn't realised you were so well schooled and was trying to word in laymen's terms.

We'll have to agree to disagree re the soot factor, because I've seen it with my own two eyes, on low kilometre vehicles.
Possibly the soot is produces early in the heating process?

Has little to do with this discussion anyway. People in the US will realise one day that there is a place for diesel Jeep Grands, and why that option is easily the most popular everywhere else in the world in this vehicle.
For me personally, I still don't know if I can sacrifice the V8 sound for better economy. I'm a believeer that we won't always have the choice of owning old school V8 power, and I'm living it up while I can

I tend to agree with you on the "gonna lose it soon" view. Our fuel economy standards are going through the roof by 2025 (if I remember correctly) - we've taken the gasoline engine about as far as we can, only way to get better fuel consumption is diesel, diesel hybrid or electric. Say goodbye to gasoline engines, especially the V8.

Although I have already made the transition, that will be a very sad day.
