There was an article in July about that engine, where you guy's been?
A diesel H2 would be interesting (since Ford's diesel Bronco probably isn't going to happen)
When you consider the size truck the V6 PSD is in and it's intended purpose, it does a pretty good job.
A lot better than the 350 Chebby gassers they've been cramming in Isuzu cab-forward trucks for years (the king of turds)
Just a WAG but I'd bet the V6 PSD is slightly detuned for heavy (up to 19,500lbs GVWR) commercial use in the LCF trucks.

It is for sure. I bet it has to be 300HP just to keep up with GM.444turbodiesel said:
I just got to drive an LCF for the 1st time yesterday. Man, what a terd that was :damnit . My 4800 would give it a run for its' money. I'd actually take the 350 gasser if I wanted to go faster. LOL

You don't want the gasser, we have two of them. :bang:
Truth be known, I'd take a UD diesel over any of them.

Uhmm..........................................I'm pretty sure that V6 PSD is going to have turbos like the 6.4. That should exaggerate the 225HP Engine's power. Look at the 6.0's those aren't rated really high. But that variable turbo helps it out quite a bit. Reliability might be a different story. Calling it terd........I'd wait for it to come out.

Does anyone have any information on what dodge is going to with there light-duty diesel. We know what GM has for us and after reading this thread i see maybe what ford has got, but nothing from dodge yet.

Hmm, how 'bout a 350hp Cummins QSD4.2?Chevypowa670 said:
...on second thought, it'll probably be some kind of Mercedes

Not to be the negative guy in the bunch. I love diesels and everything about them. But don't you think a gas engine is more practical for a 1/2 ton. I mean with diesel prices 40 cents higher than gas and gas engines in 1/2 ton pickups getting 17 to 18 mpg nowdays. You can't really pull loads with 1/2 tons. You don't have to sit and let the gas warm up for 20 minutes either. I'm just throwing this out there to get some opinions and maybe even change my point of view.

your right with the gas milege being better in gas trucks now-a-days, but ive been hearing rumors about the 4.5 duramax as getting as much as 25 mpg in the city. Now i have no clue if this is true or not but if it turns out to be I think there will be a long line of people wanting these beasts. Think about it. You will have the power of a diesel, the ride quality of a 1/2 ton and very good gas milege.

I think the whole notion of the diesel availabilitiy in the 1/2 ton for the purpose of towing is largely untrue. 1/2 ton trucks, even if they had 500HP diesels in them are going to be limited by their suspension systems to towing probably no more that 10K off the bumper and 12K with a 5th wheel. Sure, you'll still have a few clowns convinced that the only thing that matters is diesel horsepower/torque for towing, even with C rated tires and 10" brakes on their 1/2 ton diesel.circle5 said:
The real reason for a diesel in a 1/2 ton is fuel economy. Despite diesel fuel costing .40 c. more, you'll still come out ahead in dollars spent on fuel and then you have the engine longevity factor and the trade-in value is much higher factors for a diesel, too.

Well thanks guys for not blowing that out of proportion. I understand where you guys are coming from. But i'm not totally convinced it's cheaper to run a diesel than gas. With the price difference, Repair Costs, Maitenence costs, and the time you waste letting these damn things warm up. Like i said before i love diesels and wouldnt give mine up. Just making conversation so i can learn a little bit

I think depending on the resale, original price difference might not make much difference. For instance, if the diesel option cost $4500 and the trucks have a resale value that averages around $3500-$4000 over their gas counterparts after 7 years, I would say that it's worth the added initial cost.
I'm not too convinced that a diesel would be that much more in maintenance. What would cost more? As for repair costs, even if they are a little more, a diesel will more often than not have much fewer repairs than a gas motor.
On the topic of diesel taking longer to warm up, that all depends on where you live. I know that here in Florida diesels don't take long at all. I could understand in states where it gets really cold, but then you still have the option of buying a gas.
It all comes down to fuel mileage. With fuel prices where they are now, as long as a diesel motor can get 2-3 mpg more than a gas motor, it will atleast have equal fuel costs. Any difference bigger than that and the diesel comes out ahead of the gas.

Wards Automotive released a study back several months ago where they found the average resale value on a diesel pickup on average was $5,000 more than a similarly equipped gas powered pickup.
That would be all the incentive I would need to buy diesel.
As far as extra costs, here in PA, there's no emissions test, so that's a $50 svings per year. Although they hold more oil and require 1 or 2 fuel filter changes, there's no tune up required, so I'd say ove a 100K timespan, the diesel comes out about the same. Especially if you do your own oil changes.
Then you also get double the engine life expectancy of a diesel over a gas before overhaul.
If you drive 15K per year in a gas powered truck and get 12MPG around town at $3.00/gallon, you'd buy 1,250 gallons of gas and spend $3,750.
If you drive 15K per year in a diesel powered truck and get 15MPG around town at $3.50/gallon, you'd buy 1,000 gallons of diesel and spend $3,500.
So you would save $250 bucks/year or $2,500 over a 10 year lifespan.
If you do a lot of highway driving, the savings would be greater.
Of course you also have the torque advantages which make towing so much more pleasant.

Thanks Duke.
Now how long do spark plugs usually last?? Half the life of a diesel injector?
I mean spark plugs are insanely cheap compared to injectors for a diesel.
Basically everything is cheaper for a gas.
But i see what you guys mean. Thats why i posted that, to change my mind

I can't see any reason why injectors wouldn't last the full 10 years 150K miles. I've never replaced an injector because of failure in 15+ years.circle5 said:
Of course sprak plugs are much cheaper and most can go at least 50-100K before replacing nowadays. The real question is, how much more than 100K miles will the average gas truck engine go before complete overhaul? Usually after 100K, it becomes a game of chance.
One other thing: I wouldn't say you need to spend insane amounts of time "warming up". I'm sure up north like you are that you plug your diesels in at night. You should be able to fire up & hit the road after on a 2-3 minutes of idle on a cold morning. The key is to not over-rev when you first hit the road.
A gas engine can have oil that gets just as thick in the cold as a diesel.

I think its more about power isn't this new dmax rated at like 300hp or something like throw a chip and other mods and there is gonna be some crazy power out of a 1/2 ton truck. I think a chipped 1/2 ton diesel will smoke a 1/2ton with headers and a chip.
