Nissan now with Cummins power

[BrinkME]

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...

My mistake, I shouldn't have lumped John Deere in with my summation.

The intent of my post wasn't to lump all the diesel engines of the world across all markets/industries together, but to point out that generalizing an engine by it's cylinder configuration is a nonsensical point. I have always been a firm believer in the fact that "there's more than one way to skin a cat." Now the majority of people (I presume) will either believe/"know" that their way is the best, but just like the fact that there's more than one way to do something, nothing is perfect and everything has it's pro's/con's, strengths/weaknesses, etc.

I agree. The 1500 series diesels will sell like hit cakes.

I am willing to bet more will be sold in Canada than USA, other than fleet uses.

Members,

V engines are cheaper to make - they have shared crank journals & more compact blocks compared to medium & heavy duty in-line engine blocks.

Cummins has made V engines for years....V903, V28, K38, K50, QSK60, QSK78 & new QSK95. It's just that these are all big monsters above 500 hp.

The fact they are considering entering light duty automotive fray is exciting! Poor Chrysler - their shareholders sold them down the drain to Daimler-Benz.....a total disaster & cultural mismatch. That was the beggining of the road to bankruptcy, and takeover by Fiat, and now mis-read of the North American market by Fiat.

I think our country and companies are run by idiots!

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

This is true because the individual cylinder main journals in the in-line engine crankcase can take more load, unlike the shared cylinder main journals in the V engine crankcase.

But....it becomes difficult to make really large in-line engines due to really high reciprocating masses (note that the largest compression ignition engines in the world are in-line cargo ship engines, however...but hugely expensive!) and become cost prohibitive, hence the V engines generally are seen above 500 hp.

As you see from the in-line engines, they are too capable & expensive for light duty automotive use, that is why this new engine development is so exciting!

I know YOU would buy one, but the US market has a long way to come, to where Europe is, where just about any commercial vehicle has a Diesel, even the 60hp 1.5 liter Renault Kangoo used by the mailman... Here, diesel is 3/4 the price of gas and in the USA its the other way around. people that buy a half ton, dont tow often so have less need for the torque or fuel economy of the Diesel.

I am willing to bet more will be sold in Canada than USA, other than fleet uses.

The way i see it, fleetowners dont think their workers require 380hp at all, the cheaper and leaner 300hp small block diesels will do. Private individuals are more likely to want a big block diesel for bragging rights, or because they do their own towing (where larger companies will hire a trucking company)

The 4.5 Duramax, Ford 4.2 ?? and Cummins 5.0 perform better than any big block diesel 10 years ago and at current environmental hysteria and fuel prices, fleet owners want the economical alternative and not engage in the power war.

Therefor i think these new small block diesels will see their way into the 3/4 ton trucks and when these have gained acceptance, its time for the 3.0 VM on the N.A. truck market.... I dont think it will be accepted yet, its a bridge too far for both sides of American truck culture...

I prefer an inline six. 2 more main bearings than a V8 is never a bad thing.

I think it is when you aren't using the extra capability for a lot more money.

I seem to remember Sonny Pruitt in "Movin-On" saying that '74 KW W900VIP had V903 in it. But I also read somewhere some time back, theat the audio overlay sometimes was a Detroit. The remaining truck was repowered to an inline Cummins or Cat before the guys in New Jersey got it.

Cummins built V8 diesels for many years for large trucks and the military. They had a 555 and the V903. I believe the V903 is still used in the military and making over 500hp.

My Cummins wasn't any more money than a Powerstroke at the time.

It is certainly a higher quality engine.

IIRC, the 555 was used in farm tractors and did not have a very good reputation.

I got an inline 6 Cummins. 485hp 1750 torque. used to have 525hp with 1850 torque. the 600hp 2050 torque is the big one.:cool2:


Of course these motors cost almost as much as a pickup.

But back on topic would like to take a Titan diesel for a test drive. Haven't been a big nissan fan, but who knows.
