FCA(Marchionne) says diesel is dead

[Travlingman]

Doesn't look good for those of us who like diesels. Sounds like the pollution controls are killing it. Article

Probably because of the horrid mpg they would get.

In a recent test, the "e-beggars" aka TFL guys put an Expedition (3.5 V6 EcoBoost) up against a GM SUV with a 6.2L V8, both towing a 7000# trailer over the same route. The huge GM V8 beat the "Eco"Boost by 0.5 mpg, 9.1 for the 6.2L vs 8.5 or so for the 3.5L turbo Ford.

If a tiny 3.5L V6 (remember that's ONLY about 217 cubic inches) gets 8.5 mpg pulling 7000#, what would a gas V8 turbo get? 3 to 5 mpg?

There's a reason they are sticking to SMALL engines to throw turbos on...

Bingo! I’ve had the diesel bug ever since they quit being pieces of chit and actually started putting down some power.
But a twin turbo eco boost type V8 making somewhere around Hellcat numbers would get me to rethink my diesel decisions!

The small displacement EcoBoost is used because trucks are coming under increasingly strict fuel economy regulations. A big gas V8 will get lousy mileage both on the boost and not on the boost. If you want big power from a V8, just make the pistons bigger. It's cheaper than a turbo.

3/4 and 1 ton trucks are exempt from EPA mileage disclosure requirements. And anyway, re fuel economy regulations, they are NOT being made more stringent, instead they are being scrapped, linky link.

Further, I don't care if larger pistons are cheaper than turbos, my potential interest in a gasser for towing would be in a turbocharged V8. Engines with turbos are much less subject to power loss due to altitude, and generally have a torque curve more suitable for towing than naturally aspirated engines.

I have spent the last two days running a diesel excavaltor in my yard. It is a small Kubota with a back hoe and a blade. It only weighs 4,000 pounds but got a ton of work done. I used 3 gallons of fuel. This is exactly how other countries get their work done.

And I wonder how gigantic the grille would be to cool such an engine under heavy load.

Probably as big as the new Toyota and Lexus cars and suvs!

Those things look like the factory forgot to install part of the front end.

What's a millenium?
I am 67 and worked in the air quality business for years.

The new ones are quieter though. I had to drive a friends 2008 Tiffin Allegro Bus the other day. It has.8.9 425 Cummins and it was considerably quieter than our 2003 Cummins ISC 350. I’m not mechanically inclined but my guess is probably a combination of exhaust system and injectors. Meh. After 15 years with my Cummins I’m used to her rumble. :). If I want quiet I’ll drive our electric cars. :).

I can maintain and repair my 2014 Cummins diesel truck for the most part. Even my 2014 BMW diesel. I would rather work on that than my wife' gaser. It is not that hard if you take the time to get familiar with it.

Not sure if I could say the same if it were a Duramax or Powerstroke though. I am not knocking them, I am just more familiar with Cummins engines and looking under the hood of my brother's PSD and friend's Dmax just scares the bejesus out of me with all that stuff crammed in there.

Plus lots higher maintenance costs.

My diesel never was higher in maintenance costs than my gas trucks.

To be fair, the newest breed of Diesel is a far cry from the good old simple Diesel engine. It's incredibly difficult to go out and buy a new pre-emissions Diesel 1 ton these days in the States.

And todays gas engines aren't? :R LOL
DI engines
Turbos
Cam phasers
Multi cam engines
Multi valve engines
High pressure injectors
5 miles of cam chains
Muti fuel sensors and fuel systems

I've owned both and "my" diesel engines cost less to operate overall than my gas engines. Not a lot, but less. And they sure as hell pulled a LOT better.

For me, it's a simple question of what is available on the market today that I want to drive. I'm sure someone somewhere is driving a really sweet Model T that doesn't need much more than some spark advance and a little oil for the headlamp, but it just doesn't tickle my fancy.

I can buy a new gas V8 that I can maintain and repair. I can't say the same for a new Diesel. I think overhead cams and multiple valve heads have proved they can be very durable over the long run, (Ol' man voice on) and this new fangled fuel injection thing is working out OK too. :B
