swapping 150 for 250
#31
The V10 gets most of its torque at 3250 rpm, compared to 3500 rpm with the F150 5.4. Granted the auto I drove with the 10 was a 4.10 ratio and the transmission gearing is different, and the truck is 1000lbs heavier, I still think mpg would be close to the same as it wouldn't work as hard on the hills. On flat land, yes, the F150 most likely is more economical
I drive I84 between Milford PA and Harriman NY daily round trip. In the moring I have one steep 5 mile grade, and a 7 mile and 5 mile grade in the evening. With the compressor running on hot days, its very sluggish. This is where having more torque, lower rpm, and less transmission torque management may paff off.

I bought a 07 Tundra reg. cab with the 5.7 ,381hp and 401 torque and 4.30 gears.I thought it would never shift on hills.It shifted much more than my 09 Ford F150 4.6 3v with 3.73 gears supercab.I was disapointed in the truck and came back to Ford.
Sometimes you just have to try it to find out for yourself.

All the trucks that go past my house which is on a small hill have to change down weather it's a manual, Auto 6 or 4 speed in what ever engine type. I think people are expecting the new gearboxes to not change down as much when thats the whole point of them.

Ron, a diesel has 75% more peak torque, and optimal engine speeds of 1800-2500rpm with 3500rpm redlines Gasoline engines, even big truck ones have peak torque over 3000rpm, but that's well short of peak horsepower and over 5000rpm redline. There is nothing wrong with spinning a (warmed up) engine at 5000rpm. Fact: the V10 and 5.4L are the same engine design (same block + 2cly, same bore/stroke). They will behave the same, as in same torque curves, just with more of it. The weight for each pd-ft of torque is nearly identical between the V10 SD and 5.4: F-150 with similar equipment and cab/bed. Changing to a V10 SD will be a costly mistake.
The main benefit for a SD would be a manual trans because they are mechanically more efficient and will get more power to the wheels than automatics. Still not enough to cost you 6-10k to upgrade all while using 25% more fuel.
The best FE I've ever read for a V10 SD is 16mpg, empty, on flat 55mph roads. 10-12 is typical, maybe 14mpg at 70mph. 80mph, worse aerodynamics than the F-150 will be down in the 10-12mpg range.
Change your perspective and expectations and you'll save yourself the most money.

This is what happened with both 5.9 cummins, 7.3 powerstroke, and 8.1 V8. Dealers get these in on occassion and they don't stay long. One dealer got an excursion recently with 7.3. It was a 2002, and had 48,000 miles. He sold it for $2000 over retail.

Ron is correct about certain vehicle/powertrains in the past. They aren't worth more than new, but the relative used value goes up a little. GM's 8.1L is another one that went up a little in used value along with the 2003/2004 Duramax and anything with the 7.3L PSD. The V10 may bear a similar fate, but the 6.2L isn't too bad. More hp, less torque than the V10, but FE is better. The last test of 3/4+ ton trucks showed the V10 was not quite as quick loaded or unloaded as the 6.4L PSD. A direct injection turbocharged gas engine like Ford's Ecoboost engines have almost all the benefits of a direct injection turbocharged diesel with lower emissions and costs. They both can be tuned for a wide peak torque band. Maybe one of those will be worth upgrading for.
Honestly, if you are doing 80mph up hills and getting 15.5mpg for both ways, that's outstanding. My current truck has never gotten over 15mpg on any one tank in 58k miles!

In addition, while I'm not really siding with you, the $2,000 over retail is definitely not out of line from what I am hearing from my local dealer. Many of the 7.3L Superduties are selling here for substantially more than a comparably-equipped 6.0L that is several years newer. Makes me think of buying a crate 7.3L and putting it in my 2008 when this DPF stuff gets old. Of course, maybe its a Spartan tune and works then.

ronfx4, don't take this negatively, but... I think your thinking, research, and reasoning on a move to a Superduty is a little messed up. I have owned all of them, and in many cases, several of each - 6.8L V-10's, 7.3L smokers, 6.0L smokers, and my current 6.4L smoker. I drive alot of miles a year and trade yearly. One of the V-10's I had was in an Excursion. While I could obtain 16.3mpg while on the interstate with the cruise set from Illinois to Pigeon Forge, TN, (several times) the average mileage was barely 14mpg on the best of days. In the winter, babied or not - 10mpg... period. The Excursion in most all cases gets better mileage than the Superduty just because of gearing. I think the Excursions had a 3.73 standard with the V-10, unlike the 4.10 standard in the Superduty. Even the diesel Excursions seem to squeak a bit better mileage than the Superduties. So, I think based upon my experiences, you are really looking backwards.

You're the only person who think fewer gears is better. While the V10 does get about the same FE as the 5.4L both in an F-250 backed to the same 5-spd transmission, both are less than the same 5.4L in the F-150 which weighs about 1500 pounds less than a similar F-250 V10.
