Doubtful that will stop most of the younger buyers.

Or older. If they want a diesel they will find a way to get one financed.

Here ,right now, mattress's are 15% off ,the 30% off ,big discount monthly , +bonus 10% and sales tax "credit" (actual JEW) "sale"   $38-4500 (mattress ONLY) complete with ((( 72))) month faux $0 finance if 100% paid off. 

The ONLY v8 diesel I ever saw/owned with extended life and correct power band in class ( to and 3x warranty) was a BLUEPRINTED 5.7D .. 6.9 was close.

gadget was glow plug issues and common screwup.

Few of the cats held up but only when de-rated for some malfunction.

Great combination !...BIG 3, BIG OIL, super size BIG GOVT,bean counters wanting warranty + 1 mile. Too many cooks and gadgets are going to grenade .

No smoke....$8 fuel , NEW !!! bugs.........not seeing many at $30% markup,starting from $70K

I dunno, if I was the type to trade trucks every couple years, right now I would be looking at a 7.3 godzilla gasser. I like my old 7.3 power stroke, but currently I don't see any advantage to running a diesel pickup. In fact propane is looking somewhat attractive at the moment.

I still have those Matchbox cars.

Wasn't Cummins supposed to be coming out with a new line of CNG engines a couple years ago? Natural gas is flared off of oil wells. But until infrastructure is set up I suppose the CNG powered vehicles won't be practical.

Yea and probably @ 2 mile/gal. I think that Dodge or Ram or whatever is contemplating a 6.7 gasser

Hopefully it’s better than the 6.2 disaster!

No, but the price of the truck might.  

[Finney]

No more Duro junk for us. Son #2 just sold a 2018 3500 for scrap price(6,000). 186,000 miles. Would lose oil pressure after running for 20 min. No diesel shop around here would rebuild it. Reman or new motor only 17-18000. 

Replaced it with a 3500 Ford with 6.7. We shall see.

I still drive a 2000 Dodge daily with 365,000 miles. It weighs over 11,000.

At 8.3L it should have plenty of power.  It seems there is always a ratcheting up for more power in 3/4 and 1 ton trucks.

I'm still running a 93 Dodge Cummins.  It has long since been surpassed in power but the long term repair ability is amazing.

I like it. 

[1967806]

Can't see myself ever finding a way to spend over 100K for any kind of a new pickup. Guessing that engine option in any pickup its offered in will be that much. Then all the emissions crap that goes along with them...... No thanks. Im a diesel guy but that was before the stupid regulations and electronic crap.

Isn't the Cummins engine in the Boxcar Magnums an 8.3L?

Yes 505 cubic inches.

The mongoose is supposed to be over 500 hp and 1200 ft lbs to best the ford .6.7. I would bet 600 hp and 1300 ft lbs and of course dodge will have to have Cummins boost the output or engine size.

[dale560]

And GM has this just because you might need 1000 hp. Sorry that is the aftermarket one. Chevy offers a crate motor also

 

i  added pics of the gm crate 602

Someone here posted about the Cummins 6.7 "octane" a while back, but I haven't heard of any in trucks yet.  A gasoline 6 cylinder in a medium duty truck would be going full circle

[5088]

There is a larger Cummins headed to RAM, but I'm not sure when it's supposed to be released.   7.5L is what I've heard through the grapevine.

With GM launching this I'd guess they are going to try to speed it up.

[Dirt_Floor_Poor]

I wonder if any of the problems found during testing were corrected or they just decided to send it anyway. I guess it’s possible they didn’t even bother to test it and just figured the customers can sort it out.

GM - 8.3L Duramax

Ford - Rumors of 8.0L Powerstroke

Ram - again rumors of 7.2L Cummins?

I like displacement as much as the next guy, but this seems a little extreme.  I could see it limited to 450/550 and 4500/5500 platforms.  But a 3/4 ton with 600 HP and 1400 lb feet of torque just seems like a recipe for disaster.  Most DL are limited to 26,000 combined weight, but the trucks have the HP and torque for a truck rated for 40k+.
