What is the point of a 250 anymore. Payload and towing are very similar from the 150 to 250.

Only if you go with a regular cab F-150 XL 4x2. As soon as you start adding options to the F-150, those comparative numbers separate fast.

Sort of.

My crew cab 4x4 F150 has a payload of 1,830 lbs. My two diesel Super Duties, both with the 10,000 lb GVWR, had payloads of around 1,980 lbs. My F150 is rated to tow 10,700 lbs, and my last Super Duty was 15,200.

This change will give better performance, more payload capacity, and better fuel economy.
If the 6R140 is limited to 1400 lb-ft after the torque converter, isn't it overloaded with the current 860 lb-ft of torque on the 6.7? I suspect that motor generates over 1600 after the torque converter unless the computer limits its torque when the input vs output speed of the torque converter is over a certain amount.

I hope the transmission doesn't limit the 2017 6.7. I like the 500/1000 rumors.

With the new 10 speed transmission in the F150, there will be more differentiation again.

Any product with GM's hands in it can't be that Ford Tough. That'll drive F-250 sales.



(Just kidding about GM. Sort of. Ask me later when, and if, I get all the little things in my GM SUV fixed).

I wondered if someone was going to catch that.

This has been an issue for several years. The way we got around it before was to lower the torque ratio of the torque converter. Also, stall speed was set so that you could never have maximum torque and maximum torque ratio at once.

But knowing this now only makes me feel like Ford is making it cheaper and thus potentially less durable.

I've said many times in the past that if Ford were to beef up the axles, suspension and brakes on the F-150, it would serve well as an F-250.

I could see Ford in the future pairing the F-150/250 as a same model and the F-350/450/550 as the heavy duty offerings.
That is exactly what I am worried about. Is the truck being made cheaper and less durable? only time will tell.

Personally, i could get by with an f150 capacity wise, but I bought an f250 specifically for the solid front axle and the standard 5.4. I still choose an f250based on similar reasoning, and the cost difference between the two is not much.

So, adding an aftermarket converter can overload the trans in a hurry.

Curious where you're getting your payload information. The Ford site shows a F250, 4x4, CC, shortbed to be at 3100lbs payload. Comparatively, a F150 4x4, CC, 6.5 bed is at 2060lbs. That's just over a half-ton difference. Getting a HD Payload Pkg on the F150 will almost split the difference giving a 2650lb payload, though.

Payload information comes from the payload sticker in the trucks I've owned and weighed.

My '08 crew cab 4x4 PSD F250 weighed nearly 8,100 lbs empty, and it had a GVWR of 10,000 lbs. The diesel engine adds over 500 lbs to the truck.

My '15 F150 weighs under 5,200 lbs and has a GVWR of 7,000 lbs.

Ah, I see. My '04 PSD, CC, Shortbed was a heavy beast too. I think that was only a 9000GVWR...but it weighed in around 7500lbs empty w/ fuel.


So the Payload Tab at Ford.com must not take into consideration the heavier diesel engine. The F150 tabs broke it down to which engine, but not in the SuperDuty section.
