Diesel Pickup Horsepower Race continues...

[Bill Stockard]

GMC has announced the ratings for the new 6. 6L Duramax and Ford has finally announced the ratings for their new Powerstroke:

GM 6. 6L Duramax 397 HP 765 lb/ft Torque

Ford 6. 7L Powerstroke 385 HP 735 lb/ft Torque



GM unveils most powerful diesel pickup | detnews.com | The Detroit News



I wonder if that's "real" horsepower and torque that can be utilized towing a big heavy fifth wheel trailer up a 20 mile long 6-8% grade into a 20 MPH headwind? Or could it be only for bragging and advertising hype?

Yeah,the focus of the companies should be effective low end torque and duty cycle of the engine. All the rest is fluff. They still don't have an inline six.

 

[rscurtis]

Just what we need- a 400HP pickup to go along with the 300HP minivan and the 200HP economy car. Doesn't seem like we learned too much from just two years ago.

 

[FDavid]

Wow this is ridiculous. We should be up to 1000+ lb. ft by 2015. GM is claiming an 11% improvement in fuel economy as well as reduced emissions. Kudos to the engineers but my question is why does someone need that much power? If you are carrying that big of a load you should probably be driving a big rig. I will take reliability and fuel economy and simplicity anyday over the trucks that are resulting from ******* contest.

If you'll notice in the article, the RPM figures for maximum horsepower and torque are not shown which means it was probably written by car guys from a press release who have no idea what they mean... typical.

[Grey Wolf]

Good for them but I think about reliability also. I'll stick with my six in row thank you

That's exactly right. High torque at low rpm is required for launching heavy loads and for economical highway towing.

V8 engines that produce (claim?) high horsepower at high rpm will provide great acceleration but also require a downshift and high rpm on every grade.

Those GM and Furd horsepower and torque claims were most likely developed by the marketing department not the engine and drivetrain engineers.

Anyone who truly believes the silly claim from GM that their new engine which must meet 2010 emissions requirements is going to actually produce the claimed hp and tq figures AND an improvement in fuel economy is likely to also be a buyer for ocean front property in Arizona or the Brooklyn Bridge.

No thanks. My weak little 305hp cab and chassis provides all the towing power and horsepower I need.

 

[HCannon]

A proven fact, if you wont a pulling Diesel all you need is a in-line 6.

 

[Tinman]

All the hp in the world isn't any good if it's in the garage. Both those engines are brand new with new technology. Heck GM couldn't even get the engine ready for production of time. That means what ever goes out the door it a rush job. At least our 6. 7 is time tested and nothing brand new. I predict lots of problems with both these motors and I think we'll see a long more CTD on the road in the future.

 

[bheiting]

Now that diesel is back to $3 / gal. you don't hear them bragging about mileage.

I agree. Our ISB6. 7s have already gone through the new product stage and corrected some minor hardware and software issues that plagued a few 2007. 5 owners. We're not seeing complaints now and I'd be willing to bet the 2010 models are troublefree.

Furd and GM have not even begun the process yet. It may be fun to watch.

 

[JUeckert]

the ford engine is 735lbs at 1600 rpms. what were those dodge rateing's again?

Yeah when that POS motor has 300,000 then and Only Then will Furd or Isuzu/chevy have something to brag about I just don't see that happening for a very long time

 

[NIsaacs]

Competition is good. Without it we would still be driving gassers with 3 spd. autos and 4spd standards with little axles. Where would Dodge be if Ford and Chevy used the Cummins? Every manufactures trial and error has developed into the awesome trucks of today!

did the engineers send you a memo stateing it was a pos, or are you one of the engineers and you knowingly designed a pos? the trucks havent even hit the lot's yet, how bout we give them a year or two before passing judgement. . btw, i spent 6hrs today sewing up a low hr b-series cummins that broke a cam. shortly after trying to test run the engine, i find i get to spend a few more hrs tommorow pulling the head and see what kind damage there is to the top side. i knew the 2 bent push rods i had to replace were a bad indicator.

 

[Simplysmn]

I guess we will all see if there new motor's are Junk like the 6. 0 or the 6. 4 or what ever chevy is working on will last or not . I made my Choice Dodge and that's why I am part of Turbo Diesel Reg. Ford has Not had a good Motor in Yr's Maybe this 1 will be will will see . As for Chevy No Thank's I worked for Isuzu and the company $uck's

hhmm... before I post this... . let me change into my FRC's... (fire retardant clothing)

IMHO, none of the three have learned anything from the past 2+ years.

GM and DODGE did figure out that if they cry a little, big brother will cut them a check so they can go back to " business as usual". Ford STILL hasn't come off of their high horse, or admitted that the 6. 0 and 6. 4 was/is a parts departments dream and an owners nightmare. I KNOW there are dyed in the wool, blue oval guys in here that will come back with " I know a guy thats got 200K on his 6. 4 without issues"... problem is, that is NOT the norm, its the exception. I applaud Ford for attempting to do it all in-house and only time will tell if its a success, or as big of a flop as the 6. 2l GM/Oldsmobile was. . I hope its a raging success, but I will have to see to believe.

Once again, IMHO, Dodge is just as bad, if not worse... They don't have to worry with the pesky details of designing and manufacturing their own diesel engine, they just have the task of building a truck that will compliment the engine package... STILL waiting on THAT one. . The transmission is weak, the front suspension is a joke, and the interior is cheap. I know I know... the new trucks are better... are they??? Is it a better suspension package with a more robust unitized hub bearing... . or did DODGE just re-print the service manual with looser tolerances to get out of warranty claims?? Is "Death Wobble" a thing of the past?

GM. . well, I have 7 years with d-maxes so I think I can honestly say... its junk. . its a great engine if you run un-loaded and only pull a boat or camper every once awhile... I hear they do ok when chipped up and racing... Sorry, I didnt buy it to race. . When they are called on every day to pull hard... they fail. The interiors are cheap on them also...

Personally, for what we ALL pay for any of these pickups. . (Ford, GM, DOdge) the quality is completely SUB-STANDARD!!!. .

Quality from any of the three hasn't gotten better over the past several years. . its just that we as a society have gotten accustomed to "less that satisfactory" being ok. .

See what happens when I have a bad experience at a dealership!!!. hahahaha...

Everyone knows Cummings is owned by Ford... :-laf

I really can't disagree, as I do believe it's a crap shoot with any of the Big 3 vehicles, and I've had junk from all three of them. As many folks on here say, "I bought a Cummins diesel, and it came wrapped in a Dodge truck". I do believe that, on average, the Cummins is demonstrably better. I'd also point out that the GM/Olds diesel fiasco was the 5. 7, not the 6. 2/6. 5.

 

[HBarlow]

I haven't owned a Chevy since a 1970 C2500 or a Furd since a 1994 sold in 2001 but strongly disagree with the negative comments about the Dodge. I have simply not experienced the problems that many complain about.

My first two Rams provided outstanding service for 325k and 230k miles with very few repairs while used for heavy commercial hauling.

My '01 had a headgasket replaced due to small seepage and two lift pumps. The NV-5600 got noisy and was rebuilt at 302k miles. The '06 had a FCA module replaced and a bushing in the 48RE slip out of place.

Neither one ever had any front end parts other than shock absorbers and sealed bearing hubs replaced once on each truck.

The SLT with OEM upgraded seat interiors held up very well on both. The high mileage '01 finally developed a frayed edge on the outside of the driver's seat cushion from many years of sliding out and in. No window or door operators, body or dash components were ever replaced on either.
