2021 Ford E-Series Information

Ford has released new information on the upcoming 2021 E-Series, and it clears up some of the questions we’ve discussed before.

Contrary to previous reports, there is only the 7.3L V8 engine, and will come in Premium or Economy ratings. Power and torque ratings for each are to be determined. There is no mention of 6.2L SOHC V8 at all.

The only transmission listed is the 6-speed. The new 10-speed will be used on Super Duty pickups. The heavy duty F-650 and F-750 will also keep the 6-speed.

Dual alternators will be a little different than previously advertised by Ford, but still very good capacity. Maximum rating will be 397 Amps (240 + 157 Alternators?).


Since the 6.2L V8 is now out of the picture, and the new pushrod 7.3L V8 is supposedly much narrower, I hope Ford will make the engine doghouse a bit narrower to increase foot space.

Thanks for the update!
It sounds as if it's going to be a winner!

Great info..... thanks.

No mention of what the difference was between "Economy and Premium" in your attachment. Have you see any other info on that?

I wonder if that a "price thing" or "MPG thing". "Economy" might be less HP and less bells and whistles at a lower "economy" price??

Like to see the MPG on both models too.....Must be a little better than the current v10 with cleaner emissions.

Not much info on the net about this new 7.3 V8 Gas engine.

"The all-new 7.3L gas V8 is a “big block” push-rod engine that is designed for low-end power and efficiency according to Ford. Unfortunately, Ford has not yet specified the power numbers for any of the latest engine options in the 2020 truck".

"Pickup truck world is intrigued by the introduction of the new 7.3L gasoline V8 engine. The engine is referred to as a “big block” with an iron block, push-rod valve design, port injection, and more. There is just one gaping hole in the specs sheet. Ford did not announce any power specifications for the engine.

Let’s take Ford’s current 6.2L gas V8 as a baseline. It’s rated at 385 hp and 430 lb-ft of torque. Here is the power and torque per liter of displacement for the current engine.

385 hp / 6.2L = 62.1 hp/L
430 lb-ft / 6.2L = 69.4 lb-ft/L
This is just a rough estimate. Let’s see what the bigger 7.3-liter engine may be capable of.

62.1 hp/L * 7.3L = 453 hp
69.4 lb-ft/L * 7.3L = 506 lb-ft
453 horsepower and 506 lb-ft of torque is a very impressive estimate, considering that Ford’s own 6.8L gas V10 has a maximum torque rating of 460 lb-ft."

"What if the numbers could be even better? What if Ford is able to get a 10% improvement in flow with the 7.3L? This will push the 7.3L V8 estimates to: 482 hp and 557 lb-ft of torque.

The 7.3L V8 will make its debut in the 2020 Ford Super Duty (F250 and F350) trucks later this year. The engine will be mated to Ford’s new 10-speed automatic transmission."

I guess we will know more later this year on the TP and TQ and MPG rating?

Lots of buttons on the steering wheel shown in the picture to your link.... I sure hope that filters down to the RV stripper chassis. I sure wish my 2017 (2016 chassis) had radio controls.

It's been that way for years...too many "tie ins" between the chassis and the coach body for any of the manufacturers to attempt it. What would be great...if the stripped "A Chassis" came with a front cab to the back of the seats...from Ford...like the E and F Series. That would be a game changing revolution!!

Slight hijack.
Steering wheel radio controls in 100 types are on amazon for 15 to 50 bucks.
https://www.amazon.com/KKmoon-Steeri...gateway&sr=8-7

And the buttons will also do Android controls if you program them (I only own an rv so I can do the mods and catch a nap on the road.)

SRW Cutaways have had TPMS for years, and is listed as standard for 2021. It appears DRW (excluding spare tire) will be optional. It would not surprise me if that’s made part of the Motorhome Package, but I’m just guessing.


Regarding HP and Torque ratings, I have not seen any additional information. All three heavy duty engines are being re-rated across truck lines, and Ford hasn’t shown their cards yet as far as I know. Both the 6.2L and 7.3L gasoline V8 and also the diesel show TBD on power and torque ratings. For the F-Series the numbers should be coming soon since they go to production earlier than E-Series and F-650/750.

For the F-53 I haven’t even seen a fleet card with top-line specs. It could be they are making a lot of changes and upgrades.

As mentioned before, I’m puzzled by Ford not listing the 6.2L gas V8 as an option for E-Series. Historically the E-Series offered smaller engines for smaller rigs. A 7.3L seems a bit large for smaller RVs and commercial van-based trucks, particularly the 10,030-pound SRW E-Series. I just hope limiting engine choices to pushrod 7.3L will allow them to reduce engine doghouse size.

I would suspect a minimal TPMS was added after the legislation requiring TPMS on all passenger vehicles after the whole Explorer/Firestone rollover fiasco. (My Focus Electric, C-Max, Bolt, and our Escapes all have or had TPMS standard.)

Usually trucks and heavy duty vehicles are excluded from such measures but since ABS has moved on to just about every vehicle TPMS likely will as well.

Good luck getting that to work with a Thor installed radio.

Yeah I was thinking the same thing. But I might try one someday.... very cheap to gamble on.

Yeah we should have more info by this fall on the F series engines.

Like you said - I hopefully they will have a smaller dog house ....but for the small A class (Like Axis) it will be up to Thor to make it smaller not Ford. But at least the C Class RV's can enjoy more foot room?

Don't gamble; verify you have a KEY1 and KEY2 wire in the radio's wiring harness. If you don't have those wires (which a quick search shows Axxera radios do not) then it won't work.

10-4, thanks. I figured since there was so many models avaiable that one of them might work.

But if only works with my iPhone - I would be happy with that. I stream from my Iphone a lot. So this would keep my hands on my wheel more.

I haven’t seen any information as to how the “Premium” and “Economy” engines will differ in the E-Series, but you guys may be interested in noting one detail that was disclosed (probably accidentally) by Ford with the latest 2020 Super Duty Tremor off-road package. In the Tremor video, the tachometer which is only visible for an instant appears to have a significantly higher engine redline than what was previously shown for the E-Series. This suggest more power.

My guess is that Ford will have a higher power rating on the Tremor 7.3L V8 similar to when they introduced the 6.2L SOHC V8, and tuned it for more power in the F-150 Raptor. It shouldn’t affect motorhome engines, but may show the new 7.3L can be modified for more power (not that it will need it). We’ll have to see over next month or two.

Very interesting..... I just checked my old pictures to see what my Axis has for a "red line".... Well it dont have one!

I figured it was 5000 but I guess its a "Super Axis" and No readline. LOL.

The consensus on ford-trucks.com was 5200. The engine computer will not let the engine over rev.

I’ve only seen V-10 redline listed as 5200 RPM by one source and I’m not all that certain if that’s correct; although it sounds reasonable.

Ford 6.8L Triton V-10 Engine Specs

I rarely go much beyond 3,500 ~ 4,000 range because there is little to be gained, I’m usually not in a hurry, and the noise and vibration get to me anyway.

The inherent mass balance of a 90-degree V8 should be quite an improvement at higher RPMs.
