1/2 ton with torque

[kguess]

Which 1/2 ton pickup has the most torque? Since this is a big factor I wanted to know.

[JRTJH]

Here's what I found on the Ford, Chevy and Ram sites:

Ford: 6.2l 411HP/434 torque
3.5L 365HP/420 torque (ecoboost)

Chevy/ 5.3L 355HP/383 torque
GMC 6.2L 420J{/460 torque

RAM 3.0 240HP/420 torque (diesel)
5.7L 395HP/410 torque

Except for Ram they are all gassers. I do know that you needa 3:73 or lower geared axle to get the most torque. Many folks are raving about the f150 ECO boost. I believe it is the highest torque rating of the big 3 1/2 ton gassers.

Gear ratio is probably equally important when you are shopping.

2014 Tundra for comparison:

5.7-Liter Aluminum i-FORCE V8 DOHC 32-Valve with Dual Independent Variable Valve Timing with intelligence (VVT-i); 381 hp @ 5600 rpm; 401 lb.-ft. @ 3600 rpm

4.500 differential ratio.

This is our second Tundra and we love it. Just my 2 cents...

Forgive me is I sound like I'm tooting my horn here but after buying the Ecoboost I've come to understand a little more about torque range. One of the unique things about this engine is that 90 percent of the power is available through a comparatively large RPM range. 1700rpm through, I think, about 5500rpm. It's very evident when pulling. Most engines' torque range is much smaller.

That's not "tooting your horn", rather simply stating what Ford did when they designed the engine performance. The design performance range was engineered to "mimic" diesel performance as closely as possible. In the Eco boost, torque rises quickly at low RPM and remains relatively "flat" across the entire RPM range of the engine. This is very similar to the way diesel engines perform. This is quite noticeable when towing with an Eco boost.

As you said, most engines develop torque on a much more "rounded" RPM range and can't match the "low end torque" found in the Eco boost and in diesel engines. Each engine has benefits and disadvantages, but for towing, the Eco boost and diesels are well suited for most applications.

I just read an article where Ford announced they have sold the 500,000th Eco boost. So there's half a million of them out there somewhere.

I tow with the Ford Eco boost set up and I must say it is impressive. As long as you stay in its specified tow ratings it will out pull anything in the 1/2 ton trucks. It has a 3.5 liter engine but you would never know it. It does way better than the 4.6 V8 I had before. You will not be disappointed towing with it.

I just got done driving 5 hours to Green Bay with my EcoBoost and Passport. As others have said the low end torque is very impressive. I love cruising down the road at 65-70mph with the engine only turning 2,000 rpm in 5th gear. Sure beats screaming down the road at 3,500-4,000 rpm for 5 hours.

Just got home from pulling 700 miles to virginia. Went from 500 - 4000' elevations without an issue. Cruised at 65-70 on interstate with ease. Btw, towing 36' outback toy hauler. The tundra did well thru and thru.

Nissan will be releasing their truck with the cummins V-8 turbo diesel, I have heard that Toyota will likely be sharing the same engine with them, but have no proof to back it up. I cannot find any firm date of Nissan selling the cummins to the public yet, or any confirmed HP or torque ratings. When they do release it I think they will have one heck of a solid truck.

Amen! I love mine! Night and day comparison to the 5.3L Chevy I had before.

Just got back from a 500 mile trip to Central California towing a 28BHSWE Hideout with a F150 Ecoboost. We went up a 6% grade and found by locking it in 3rd I was passing others towing and semi's. Couldn't believe the power in that 6 cylinder. I actually had to let off the gas to slow going uphill.

We all certainly hope you are not pulling your rv at that "crusing" speed.

Why not? I have done over 5,000 miles on this camper without an issue at that speed, including a 10 day driving to central TN.

For one your tires are only rated for 65 mph max. Think safe not fast.

It would be an interesting statistic to see how many blowouts occur above and below the max towing speed rating. I mean blowouts that don't occur due to road debris, etc.

I towed mine at a pretty constant 62mph on my trip and was routinely passed by other campers going what I expect was 70+. Is it really an issue or more of a perceived issue/liability issue with the manufacturers.

[Festus2]

Anything that I have come across regarding reasons for tire failure does not mention excessive speed as a contributing factor. The major reason by all accounts is improper inflation - especially under inflation. Too little air pressure causing increased flexing which in turn causes overheating and finally tread separation.

Other obvious causes of tire failure are impact, punctures to name two of many others. Further down the list is manufacturers' defects which are very hard to actually prove and are, much to lawyers' delight, prove to be a great source of income.
