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.

https://jalopnik.com/why-the-ford-super-duty-s-7-3-liter-v8-makes-only-430-h-1836880836

“The focus for the 7.3-liter was total capability as delivered in vehicle. We have class-leading peak torque, but we valued capability from 1,500 rpm on up over obtaining an even larger advertised peak torque. All versions of the 7.3-liter are capable of delivering over 400 ft-lbs from 1,500 rpm on up. We believe this large amount of torque from low engine speeds is exactly what a heavily loaded vehicle needs for good drivability.”

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 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.
