HD Rumble in the Rockies - Chevy wins

[Timmy!]

Here's a dynochart of 2 trucks at altitude (corrected) with the same engines. I think Ford just needs to recalibrate the computer for high altitude and this would be a different story.

... The Ford should have been accelerating much quicker according to your chart and the dyno chart facts.

This^^^ is what I was getting at. Perhaps they got a sub-par Ford for this test?

How do ya tell the difference

[91Terminator]

Opps my bad i wasn't exactly clear on what i meant.


I dont not care if the GM won or is better at climbing hills or not.

I want to know and will do some research to find out what Ford engineered the gearing and fuel system, ECM/PCM for the optimal power curve. Also i wish there were 2 things in this test that arent there.

I wish number one there was i video. And number too i want to know who did this trip with the best fuel economy.

Since this was put on or helped by or sponsored by GM i can guarantee you that GM said go get out truck with these specs. Because they know what Gearing and specs are optimal for this test.

The video would be nice because i believe according to the specs and the charts given form you that the trucks were fairly equal till about 35 to 45 MPH from there the Chebby took off i am sure and i bet the video would have showed this. See i believe if the ford had the proper gears it would have had a better power curve then it does with the 3:73.

For example:

Ford 3.31 Gear/Chebby 4.10 Gear

1. 13.14/12.71 meaning the chebby has to spin .43 more RPM same distance
2. 7.68/7.42 meaning the chebby has to spin .26 more RPM same distance
3. 5.03/5.78 meaning the Ford has to spin .75 more RPM same distance
4. 3.80/4.10 meaning the Ford has to spin .30 more RPM same distance
5. 2.84/2.91 meaning the Ford has to spin .07 more RPM same distance
6. 2.21/2.50 meaning the Ford has to spin .29 more RPM same distance
i believe

That is about as equal or close as the get. I am not saying this is the best gear for the ford or the chevy all i am saying is just cuz they both have 3.73 does not mean the are equally compared.

I would like for an independent company like boattest.com to do a comparison of both trucks all around as equal as they get.

And as for fuel economy i am willing to bet that the Ford got better milage on this test and that is why its not in there, so for me and the guys that buy these trucks for work i would be willing to bet they would want the more efficient one not the faster one. if i was a shipper or a hauler i want ever mile out of the gallon i can get cuz i would make more money that way. Ford is not trying to make the fastest heaviest pulling truck they are trying to make the fastest heaviest pulling truck that gets best mileage.

How do ya tell the difference

I don't think that it is possible to tell

[Timmy!]

Actually I would bet the Chevy got better fuel mileage since the Ford is delivering their best mileage with the lower gear ratio. Also, the mileage wouldn't be equal because they had to run the Ford up the hill 4 times but only ran the Chevy 3. If you look at their other tests on that site, Chevy was getting better mileage than the Ford in all but one category and they were doing it with 3.73's vs the Ford with 3.55's. I can't believe you are worried about tiny numbers like .43 rpm. Seriously? It's not the gears, it's not the rpm, Ford has an issue with their tuning that will probably be fixed for next model year. It's a great truck with a great powertrain, they just lost this test by a huge margin.

Pickuptrucks.com is an independent company AND they hired Ford's factory test driver to drive both trucks. Pickuptrucks.com picked them but GM wanted the test because they obviously knew that Ford had a hole in their electronics at altitude and went for the kill. Smart on their part.

The reality is all three diesels can pull like billy goats up a hill.
Yes Dodge would be over the towing limit with their 3500 Dually.
Most guys hauling their slide in campers on their SRW 1 ton trucks are over their limit as well no matter which brand they own.
I was 1200lbs over the GVWR with my 07 F350 hauling my slide in 05 Arctic Fox 860 camper. The GVWR on my rig was 11,400 and I weighed in wet at 12,600. This weight was not with my 22V or my AVY in tow so you can figure another 500 lbs tounge weight added to that.
I would have liked to see how Dodge would have numbered out on the test.

I pretty sure i made my self clear i dont care about the rpms or who wins. I just want to see an apples to apples test of all the trucks.

Agreed they all get the job done very well. So it comes down to little thinks like interior features, and comfort, and efficiency, and as i stated before not supporting government motors.

I like the fact that the Ford with GPS tells you not only where the nearest Diesel Station is, it also tells which one is cheaper, when the low fuel light comes on. Whereas the chevy just find the nearest diesel station. That is a great feature to me.

Blue Oval!!!

[dom w. forte]

I think everybody is missing the point, the Chevy and the Ford made it up and back, where is the Toyota and Nissian?
Now that should start some comments, right( nobody )!

[Ewok]

Ok, here is the obligatory Toyota comment. I bought my 4Runner to tow my boat. I just weighed my boat and trailer and its just under 6K#s with a full tank of gas and all our gear. The truck is rated to tow 7K#s. It pulls the boat great, has 4WL and a center locking diff to pull out of the steep and slippery launches. I do not plan to tow 18K#s or drag race ANYONE up a hill in CO with my boat in tow. I'm happy with the rig and if I have more kids or stuff to carry I'll get a bigger truck

[Ewok]

Counterpoint, I looked at the Toyota website a few weeks ago and noticed that the tow rating for the Sequoia is 7,000, the Gross Vehicle Weight Rating (GVWR) is 7300 but the Gross Combined Weight Rating (GCWR) is 17,280. It is built on the same frame as the Tundra, with towing capacity of 9,800. This is very confusing, especially since last year the tow rating for the Sequoia was 9,100.

[islander033]

... See i believe if the ford had the proper gears it would have had a better power curve then it does with the 3:73...

So you are saying that if the Ford had taller gears than the 3.73's to more match the Chev's gearing, it would have done better?

I would guess that it would actually tow worse due to less mechanical advantage.

[chpthril]

I pretty sure i made my self clear i dont care about the rpms or who wins. I just want to see an apples to apples test of all the trucks.

Oh, I gotcha, you are saying the test was not fair because the Ford is not in the same league as the Chevy and would need to be re-geared in the aftermarket in order to compete with a Chevy off the assembly line. I'm with ya now
