Anyone interested in the new Tremor, 7.3 liter gas engine, or 10-speed transmission? I find that configuration interesting, but am not well versed on Super Duty trucks. Local dealer has one, but with a Powerstroke.

My sources say the Tremor introduction is not for another couple of weeks. Those tires don't look like 35"s ? Go with the Godzilla..

Tremors are out, I have seen several for sale on Autotrader. I don’t exactly need a 3/4 ton but the Tremor with the 7.3/10speed really has my attention

From some sources it is supposed to compete again the Power Wagon. It still doesn't have all the Power Wagon has. No winch. No front locker (not even sure if there is a rear locker.) No disconnecting sway bar. It does have a more powerful motor and bigger tires and can haul and tow more though.

Tremors have a rear locker, front limited slip. I definitely still lacks the winch and disconnnecting front sway bar, but it also manages to maintain 3/4-ton level payload and towing capabilities which the PW doesn't. It's a trade-off between ultimate off-road capability and tow/haul abilities.

It's definitely a Tremor, bold new graphic, and all.

Tires measured 34", and not uncommon to lose ~1" once on the vehicle vs. the tire spec. For example, the tires on my Tundra are supposed to be 32" but measure 31" in real life. I bet rim width also plays into it as well.

The FX4 next to it also had tires that measured 34", but on 20" wheels. The Tremor had 18".

I've seen exactly one dyno report on the 7.3 and it put down around 360hp and 405tq to the rear wheels. They were expecting a bit more. Same truck was giving close to 14mpg on mixed driving, and it did look like a Tremor. Saw it on Youtube.

Tranny sucking up 70HP and 70Tq. Ouch, about a 15% parasitic loss for both.

I stand corrected. I checked back with my source and found that the Tremor's are indeed out there.

You are spot on. As I understand it, this was as they say "By Design".

I don't think 15% is that bad really. Anything under 20% seems reasonable.

Design goal for the 7.3L was 400 ft-lb starting at 1500 RPM, and long term durability. There are some torque-speed curves online, and they show a really flat torque curve, with decent gains over the existing 6.2L.

What's the sticker price?

Pretty much industry accepted standard to lose 15% of the power to the drivetrain w/ a conventional automatic w/ a torque converter. Standards and dual clutches can approach 12%.

14 mpg is what I got mixed use driving with a ‘14 super duty f-250 4x4 crew cab with the 6.2 liter. I put about 70,000 miles on it.

If you were on the highway going 55-60mph, your mileage went up significantly.

But.........it had no low end torque to speak of, but I read the 7.3 ‘s torque curve was very flat and you got the power band quicker . (Around 2,000 rpm)

The 17+ 6.2s are supposed to be much better than the 11-16 in that regard, or so I've read - no first hand experience. Will definitely be interesting to see what kind of mileage both the 6.2 and 7.3 with the 10 speed net.

I don’t think 14 mpg is bad really for a gas super duty .

I like pre emission diesels a lot, would not even consider a new one with all the garbage they do to them. Have several friends that have spent big dollars because of that emision stuff. Happens just out of warranty, how nice.

This is a solid alternative and I give Ford a thumbs up for bringing this to market.

Just saw on TFL Truck the Tremor is getting an optional 12,000 lbs. Warn winch for $3000 more.

I test drove one yesterday. Not because I want the Tremor package, which I don't, but because I wanted to try the engine.
It ran well in the 12 miles or so of mixed driving I did. No powerstroke, but impressive for a gasser.

I imagine on a regular 3/4 or 1 ton without the lift and oversized mud tires the Tremor has it would have even more power. After 25 yrs of driving nothing but diesels, I'm considering the 7.3 gas.

In a 2020 F250 Lariat Crew Cab, the 7.3L gas engine is a $2045 up charge over the standard 6.2Lgas engine. The 6.7L diesel engine is a $10,495 up charge over the 6.2L engine. FYI

Maybe up there, down here the up charge for the 7.3 is $1700 and some change. They propably put block heaters on yours up there, that my be the difference.

Im definitely going to keeping an eye on how the 7.3 performs with the 10 speed tranny over the next year or so. Will consider it when im done with my current f150. May even look at the Tremor package...

Buying the first edition of a new engine/transmission platform is asking for trouble.

Thats why I will wait and watch...be a few years before my warranty is up I hope then I'll look

If anyone in/near NE is looking for one, shoot me a PM!

I have a '17 F250 with the 6.2 and the mileage is around 14, love the truck but it is not a commuter vehicle for sure (unless your commute is short).

Anyone take the plunge and buy a Tremor or 7.3 liter?

Good to see that you revived this thread.

I've had a F-350 with the 7.3 for about a month now. First gas pickup I've owned in 25 years. Previous truck was a 2013 Powerstroke F-250

So far I'm pleased. A lot of power and makes it down low where it counts.

Pulls well, I weighed a little over 20,000 lbs the other day hauling one of my tractors. It did fine, yes of course it revved higher than a diesel would but I was surprised how low the rpms did stay for a gas motor.

MPG has run between 13 and 14 running empty, combo of town and highway. Again not bad for a one ton p/u with big block gas motor down here in Texas. My 2013 powerstroke only averaged 16mpg doing the same, and here gas is 50-60 cents a gallon cheaper on average than diesel.

Did I mention it was $9,000 less than the same truck was going to be with the diesel option........

For those who have driven the 7.3 did it have a lag when you pressed on the gas pedal? That is one of the reasons I didn't get a Ford when looking at 2018s in 2017. Whenever I pushed on the pedal it would take a full second or more to get up and go and act like it was shutting down power. I ask the salesman about it. He said all Fords with that other motor do that. Took it back and quit looking at Fords.

Thanks for the info, tx270. The 7.3 spark-ignited engine seems like a great option.

I don't care for diesel engines for various reasons, especially the most recent after-treatment systems.

Jason

tx270,

I forgot to ask, but the 7.3 came standard with the new 10-speed? How's it behaving in terms of downshifts, in stop-and-go, etc?

Thanks again,

Jason

Yes, the 10 speed is the only transmission you can get with the 7.3. It has done fine so far, shifts smooth. However I drove a 6.7 powerstroke with the 10 sp and did notice some hard downshifting a couple of times.

Thanks again. I appreciate the feedback.

Jason

It didn't take the aftermarket long to get things rolling. Whipple now has their Stage 2 supercharger getting ready for release. 700 horses and 750 torque at the crank. That's getting right up there with a Hellcat engine, but in a Super Duty. Interesting possibility.

Whipple 7.3L

I would opt for a Skateboard over any Chrysler product.

I thought so too for a long time and the older ones for sure having driven some at work. However, I did get a 2018 RAM 3500 diesel and have been happy with it. There are a few things I don't like such as a steel bed that dents from weight that it should carry and a small fuel tank. It doesn't get any better mileage than my old GMC 6.0 when both are towing, but it has a lot more power. Everything else works and has been great since I got it. I wish it had auto 4 so we won't have it as long as we had planned most likely now that they and GM have that in their heavier trucks. I like the Tremor too and may take a serious look at it if it has the same thing.

JaH,

Are you referring to partial 4wd that engages the front axle when a rear tire spins? Otherwise, the system runs in 2wd?

Jason

I believe that is it. We have it in our Suburban and did have it in my 2000 GMC 2500. If any of the big three had it in there 3500s at the time I would have bought that one no matter what. Love that option.

I hear what you're saying. My Tundra breaks the rear drive tire(s) loose a lot on wet roads, empty, and even on dry roads. Even at freeway speeds, at times. And it's not like the tires just spin, the ECU cuts fuel. This sucks. Although a minor complaint to some, it is my biggest complaint with the truck, besides the small fuel tank.

My 2003 GMC Yukon XL, which was a 3/4-ton, had 4-auto and it was great. The 4wd was partially engaged, and sent power to the front wheels when needed. Had an old Exploder, and although clunky, the 4-auto was functional. The owner's manual even stated that unsual noises might be heard from the drivetrain

I think the heavy duty trucks and Toyota skipped the 4-auto feature as they couldn't make it robust enough. But that is just my guess. I've heard that transfer cases with 4-auto are more difficult to make durable.

My solution for the Tundra would be to install a cone-clutch, limited slip. But, I don't know if it would be as good as 4-auto.

Yeah, we had to replace the system in our suburban at ~200,000 miles because we uses it all the time during the winter. It was less than $500. But I would rather pay that than lose a loved one to slippery roads. Matter of fact my wife rolled our 2000 GMC because she didn't turn it on. The road was dry and all of the sudden it turned to ice. We had a freak rain storm at below freezing temps on the pass she had to cross over to get home. I firmly believe if she had had it on she wouldn't have lost control.

Rolling a rig is scary. Glad she was OK.

Jason

Thanks. Yeah, I had just talked to her on the phone a bit before. She told me she was getting ready to come home. She was taking longer than usual she works in a ER so sometimes thing happen that causes her to be delayed. Next call I got was from her telling me she was in the ER getting looked at after the wreck. She apologized for the totaled truck. Hell, I could care less about the truck and still don't.

Auto 4 is the way to go.
