Why a V-8 diesel?

[JDiepstra]

With all the talk of how much better an inline 6 engine is, why am I hearing that the new 1500 diesels will have a V-8 Cummins? What happened to all the talk about better fuel economy in a 6 cylinder and less parts to break and replace and all that? A smaller engine with more cylinders when the old method has been said to be the best way to go? What gives?

I thought it was a v 6...

Smaller cylinders but more of them equal less emissions.

It is more than likely driven by the HP freaks at Chrysler who don't anything about Diesels. Well Ford and GM are doing it. duh!!!! Idiots like this will be the down fall of Chrysler if it is not already to late.

No the main reason they are going with the v-6,v-8 is becuase the motor isn't as tall and as long, and you can fit it in a smaller engine bay.

RPM i bet

That's been the reason since forever.



It's good reasoning.



Lower Center Of Gravity, more power per space used in the engine bay, and hello,, it's a "V" Engine, Americans Love "V" Engines.

Americans Love "V" Engines. Merrick

That's the primary reason last I heard. You're not gonna get a guy out of a Hemi-powered truck that has less cylinders. Even though the common-rail ISBe170 4 cylinder would do the job admirably, probably get better fuel economy, last longer, and have virtually no development time. Oh well.

I have a friend several actually that work for Cummins at an assembly plant they have told me that these (v6 and v8) engines have been designed for quite some time and they have been looking for customers for them.

Also , Dodge won't be the only customer for these engines as they already have another automaker that I guess has signed on with this engine program.

Why a V-8?

Some of the previous reasons for v-8 are true, but the biggest reason for a v-8/v-6 is that some or all of the development costs were paid for by our government (EPA I think). It was a demonstration project for 2010 emissions. This was mentioned in an article in the TDR magazine. All comes down to $ ! No or low developement costs = main reason!

well you would think that cummins would

tell them its not a good thing it is there

name on that motor

 

[SShafranko]

Nissan?

Suing international..... FORD? No Way

I think smaller displacement vee engines are a good fit for light trucks since they won't spend the time towing or hauling weight like the HD trucks do. Less need for torque, plus the drivetrain doesn't have to be so heavy (weight and cost savings) and at the outset Cummins specifically wanted performance to mimic similar-displacement gas engines.

Another biggie (back to the weight thing) was Cummins was shooting for engines weighing as close to their gasoline counterparts as possible. They came pretty darn close to the weight of the 360 for the 5. 6L V8 and similarly to a V6 with the 4. 2L diesel.

Personally I'd prefer a light truck with a V8 if I didn't plan to tow with it much, it oughta cook with the right mods.

V-8 lots of power in a small package.

Here's a pointer to an article about just that:
