1/2 Ton Diesel?

I was thinking about this the other day coming back from Lake Alan Henry, in West Texas... Are any of the 1/2-ton truck makers thinking of coming out with a smaller diesel? It seems to me that they are missing the boat, somehow. The goobermint will mandate better fuel economy, soon, and what better way to maintain towing capacity and yet get better mileage? Maybe I'm all wet, but I thought I saw something on a site the other day where a Toyota in Europe (?) was pushing 400 horses and getting 32 mpg... Why are the TV manufacturers not doing that in the USA? I believe they'd sell like hotcakes...

Correct me if this is bogus, please... Post if you work for one of the auto makers and/or have better insight...

As my bud Charlie says... Peace. Love, and Groovy!

At one time before the crash GM was developing a 1/2 diesel.

Last I heard was Dodge had been considering a 5+ liter V8 Cummins, Ford a version of the diesel used in the Range Rover and GM had one as well not sure what the actual configuration was though. They all fell by the wayside when the downturn happend a few years back so who know where they all are in the food chain anymore.

Actually Nissan and Cummins are testing one as we speak for the Titan.

Numerous diesel programs were put on hold when the price of diesel exceeded the price of gas by 15%. GM and Ford for sure.

Very interesting... I agree with some of the comments about the HP being a bit low. However, those that design all of this stuff, (ie. those MUCH smarter than me), will more than likely solve the HP/fuel economy delima in a few years, and keep the torque figures up where they need to be.

I've been wondering why the auto makers hadn't done this, and apparently, it was in the works before the bottom fell out.

Thanks,

Which no doubt played into the birth of the ECO Beast F150.

It stands to reason... One is paying a 15% fuel premium after paying a 30% premium for the diesel engine at purchase... So, in order to come out even the diesel will have to make lots of horsepower and torque on lots less fuel. But again, I think, in light of what has been done with gasoline engines, the engineers will be able to come up with a 4 or 5 cylinder diesel that will get awesome mileage and still deliver when it's loaded down with my TT... someday... As for now, I can buy a lot of gasoline for the difference... even at $4.00 per gallon.

I am not sure there would be a high demand, at least in our specific market - towing.
Anyone who wants to pull over 8500 lbs usually fall into the "you need a 3/4 or 1Ton+ diesel" market. For anyone under 8500 lbs, a gasser 1/2-3/4 ton seems to work (I am not starting that debate so please don't either).

In order for me to consider moving back to a diesel, it would need to get at least 25 MPG city and Hwy driving non towing (my Ecoboost gets 18-19) without any aftermarket hardware or deletes. The whole water in the fuel system, thus not covered under warranty issue needs to be resolved as well. I can't see a 1/2 ton diesel not having the same issue and possible voided warranty.

I love the thought of a diesel, but the EPA crap really chokes out the benefits if not towing every day (or hauling a large payload).
I would think the 3/4 & 1Ton market would be the first to really see any improvements when they manufactors figure them out in a few years like someone said.
When that happens, would there still be a market for a 1/2 ton or would the 1/2 ton just become extinct?

Anyways.. just some thoughts.

Cummins has had that little 4bt 4 cylinder around for a while. You need to check out the video's for that little rascal! With turbo that is one little engine that could!
