Nissan now with Cummins power

Lt CHEG · Aug 20, 2013

That's great news. The more new diesels out there the better. Maybe this will drive Ford to put their smaller Powerstroke into a pickup and GM to put their 4.5 liter Duramax in their pickups. GM already committed to building a pickup with a smaller diesel and rumor has it that it would be the new Colorado. Maybe they will also bring out a half ton diesel too.

I wish I could get a 3/4 ton pickup with an engine in this power category too. I need the suspension to handle the weight of my tractor but I couldn't care less how fast I drive when I've got 16,000 pounds behind me. Heck I would have gladly opted for a 5.3 liter V8 in my last 3/4 truck instead of the 6.0 liter if I could have. I would love to get the better mileage of a smaller engine the 2/3 of the time that I'm not towing and would gladly live with fairly sluggish acceleration for the times that I'm towing.

Regardless nice job Cummins and Nissan!

I seen it. Was actually at Cummins yesterday for some other business down in Columbus Indiana. I was confident it was coming.

I am still not sold on diesel in a 1/2 ton. Especially with engines like the Eco Boost.

$11,000 for a Dmax option up here, $11,500 for a Ram Cummins... I can buy a lot of gas in a 1500 for that!!

Should of hit me up for lunch

I worked on the development of the Bradley Fighting Vehicle power train which was powered by a VTA 903 originally 500hp.
It was uprated to 600hp and we also tested 660 and 700hp versions.
I spent thousands of hours operating the dyno test cells and we ran them hard, there were test points that required 20 minutes at a full 600hp at 2600rpm, that's 1212 lbft of torque.
Tough engine ran it hard and at 2600 to 2800 rpm.
We had a couple failures with the 500hp versions where some rods & block were scattered around the room.
Cummins has been building V8's much longer than GM or Ford and they know how to do it!

I bought my first new truck in 1990 as you may have guessed by my signature it was a 1990 Dodge W250 CTD.

We ate at the airport. If I have some notice next time I will.

A bit OT here, but it still amazes me how many people don't realize that a V configuration in a diesel isn't that uncommon. I presume it's due to the fact that most diesel engines on the road today, both here and abroad, are of the inline variety and a lot of older (and some newer) V configuration diesels have set a poor reputation for themselves.

I laugh every time I see someone post "real diesels are inline" . . . I guess we better go tell all the major diesel manufacturers (Cummins, CAT, Detroit, MSU, John Deere, etc.) they should stop building V configuration industrial engines. I wonder what people would think of the 50 liter v12 CAT and v16 Cummins we use in one of our product lines all the time.

This was in no way intended to be insulting toward anyone, and I realize this isn't every day knowledge for most, but with the resources we have at our finger tips these days I guess I felt like more people would have been privy to this information.

This statement is true when taking in concideration that the Cummins ISB is based on the heavy duty industrial QSB, where the Ford and Chevy V8's are automotive engines of a lighter build, therefor not suitable for continuous industrial duty.

And JD never made any V configurations... and the other manufacturers you mention, only make them for real large displacements, where production volumes are lower so it makes more sense to build a modular engine family with the same basic design, but an increase in the number of cylinders.

High production volume industrial engines are all inline, the V8 is disappearing even from the big rig market, because weight is much more important these days.. In automotive, they use V configurations are for the short and low block dimensions that easier fit under a car hood, (compactness) or because V8 sounds more appealing than inline 6 in grocery getters. I wouldnt be surprised if the 4.5 Duramax, the smaller Ford V8 diesel (known from the Landrovers) and the Titan 5 liter Cummins will beat a hole in the market share of the big block Diesels from Ford, Chevy and Ram, for fleets. Only private individuals will keep buying the big diesels for bragging rights.

The VM 3 liter engine in the Ram 1500 just isnt comparable, the power to displacement ratio already says that the 5.0 Cummins will be a much more heavy duty engine than the VM in the Ram...

I think Sergio Marchionne (Fiat CEO) will realise he shot himself in the foot by sticking to his European visions, giving Nissan the opportunity to get this Cummins and sticking RAM with the (in Europe) poorly reputated VM engine...

I have also heard that all other things being equal, in inline configuration (even in a gasser) produces more torque.

A 5 liter V8 will more likely produce less torque than a 5 liter inline 6, if the bore/stroke ratio (relative, not the absolute dimensions) stays the same. Because the stroke will also be longer, giving more leverage on the crankshaft. And the relative size of the valves and inlet channels will be bigger, making it breath relatively easier than the V8 when the revs go down...
