Is the new 4.5 Duramax a good option for the HD Series?

 

[durallymax]

yes as a base motor

 

[mmangels22]

I am not totally convinced yet that this motor has promise in a HD truck. So far all evidence has pointed out it would be in a 1/2 ton platform. So i voted maybe.

I think that it might be a good option as a replacement for the 6.0L for the base model trucks. It would give the consumer the option of having a diesel engine without the expense of the fullsize Duramax/Allison option. There are a lot of people who would like to have a diesel but can't justify the added expense of that $8K option right off the bat. So therefore the 4.5L would give a more affordable option.

I think I'll believe it when I see it. I don't have much hope that this motor will ever see production....

 

[durallymax]

with the amount of money invested into it I think it will, it holds a lot more water than fords motor which was already made in europe so they arent loosing much.

 

[mmangels22]

They won't scrap the concept or the motor, they have to offer something everybody can be happy with. However they should make a motor like the 6.6, that can do the same things and have the same strength but in a smaller package that can get 30 mpg.

What I'm saying is that is with GM in the shape it is in, I don't see them releasing it anytime soon, if ever.

GM has staked their whole existence on the VOLT and I don't see them releasing anything new until that hits the market and is a success. (Who knows if GM will survive long enough to even release the VOLT?):noidea:

Personally, I've never been a fan of any of the Big 3's 1/2 ton diesel plans.
The general public will not pay the premium for a diesel engine with the spread in fuel prices of $.60 to a $1.00 more than gas and the increase in mileage is minimal. So where is the benefit of the diesel? Remember, this is the 1/2 ton market and not the 3/4 ton and up market that GM is targeting with the 4.5L engine.

IMO, if any of the domestic automakers were serious about really transforming the 1/2 ton market by introducing a diesel, why not 190- 200hp and 375-400lb./ft. of torque or somewhere around that? That used to be plenty enough in a 3/4 ton just 10 or 12 years ago...

This is just my $.02 and maybe I'm all wrong....:noidea:

 

[cumminstrokethi]

I voted that they should stick to the 1/2 tons... If you're gonna buy a 3/4 or 1 ton, get some power behind it... My .02

 

[RodZZilla]

The power is close to what the LB7's had. I think it could be a decent base engine if the $ is right. I think they would do well to have a 1500 HD w/the Semi-Float rear and the 4.5.

I wonder how a 6.6 would do w/the reverse flow heads.

 

[BoostN]

I just think it needs to be the 1/2 series only. It's a perfect motor for the 1500HD series.

Keep the 6.6 in the 3/4 and 1 Ton series.

 

[Zebler]

bring back the 1500HD

 

[whatnot]

bring back the 1500HD

Did they ever really get rid of it? I thought they just changed the name to 2500. That makes it a lot simpler to get parts. I used to have a 1995 light duty (6bolt wheels) 2500 and they parts places always looked it up wrong. I eventually just started telling them it was a 1500 to get the right parts.

How would it be any cheaper than the bigger motor...there really can't be much of a difference in price...they are both V8's so same amount of pistons ect.

I also voted for it to stay in the 1/2 tons.

 

[BoostN]

My other issue with 4.5 in the 2500HD series is buying one, just think when looking used/new your going to wonder if it's got the baby Dmax or the big daddy.

Stick to the 1500 series..

 

[Max Attitude]

Yeah, imagine finding one that has everything you want only to find out it has the little motor. :doh:

 

[dieselriceHD]

I think it will work out great in the 2500 except for extreme hauling maybe
a lot of people dont use there diesel to there fullest anyway

Production costs, materials, etc.

 

[corvette_dad]

i think it would be better in the 1/2 ton and suv models. if your buying hd truck it's probably for hauling, so i think you would want the bigger engine.
