That's the future. When batteries are gone at least.
IIRC, all of the ERS systems Ford/gm/Toyota looked into, would cost as much as the diesel upgrade and weigh as much.

We'll see it in cars first. Rear wheel drive. No xfer case, no front drive shaft. Just a front diff and a front electric motor. AWD through electricity.

Toyotas race car for example. I think it's rwd, with a front electric motor for awd. I believe the rear has a transmission, and rear electric motor.

Batteries are what's killing the innovation.

The AWD Prius already has that.

I had a 2008 F-350 with a V-10 and I liked the engine at the time, the rest of the truck not so much. Yes it was wheezy in the higher RPM range but it pulled hard for that era's gas engines. However, the 5.4 in a Superduty was a gutless sled of and engine so it really made the V-10 shine. And my current 6.4 Hemi would spank that V-10 in a race.

That being said, if this 7.3 works out to be a good engine maybe I'll consider switching back over to the dark side in a few years.

Here is an article published this morning with more spy pics. Also some numbers are being posted. It will beat GM's overly complicated new offering.

There are some links to previous articles with more facts.
This makes me kind of excited for this motor. Has the potential to last a long time. Dam I'm trying to stay debt free and all this potentially awesome stuff keeps being introduced! It's ridiculous!

So which one would make sense for the reasons we all are here for - expedition?
1) 6.2 6-speed
2) 6.2 10 speed
3) 7.3 10 speed
My opinion would be what ever makes the most power and has the best fuel economy, or a good ratio of both. Being ford has not released the power numbers for the 7.3, I don’t think this question can be answered adequately yet.

My guess is for most people the 6.2 and 10 speed. The 6.2 is a great motor and putting a 10 speed behind it will probably help it much like the 10 speed helped the 5.0 in the F150.

The 6.2 should also weigh less, leaving more weight for cargo.

Now, for me the 7.3 and 10 speed would make the most sense due to the fact that I would be towing a 5th wheel and don't like to slow down for hills...lol.

Also, if performance parts start showing up for the 7.3 then it will be a whole different ball game. :)

#1, because it's mature technology that has been very reliable.

I don't need tons of power or fuel economy to go camping in the woods. But It's impossible to get a tow truck to my camp site. When the other options prove to be reliable, it'll be a wash.

We are in the same boat. We have lived the debt free life for years. I was recently hit with 3 repairs on my daily driver within days of each other. None of which could have been seen ahead of failure. My daily has 200,000 miles and is time to move it to a secondary vehicle. I was considering a vehicle that was 2 or 3 years old, but this has given me pause. When I say daily driver, it is not necessarily used everyday. There are some days we are home all day. Days I work it is less than 60 miles round trip. I have no problem driving a large vehicle as a primary vehicle as we are rarely in urban areas. A new F250 or F350 could very well be the last vehicle we need based on the service life of our other new vehicles we have had. Yes we drive them till the wheels fall off, but we'll maintained. Now if I can get an F250 with crew cab and an 8 foot bed with the new 7.3L.

Going to have to come up with something to differentiate between 7.3 gas or diesel. 7.3G 7.3D maybe

Teslas already have AWD with no driveshafts, transmission, or t-case. 4wd would just be an over-the-air software update, as would 4L.

A cool trick that dual motor AWD vehicles can do is have different ratios in their 2 differentials, effectively giving the vehicle a two speed "transmission," a least when the vehicle doesn't need to be actively powering both axles, managed every fraction of a second.
In some cases the AWD is more efficient than the RWD equivalent vehicle.

Obviously I don't know the costs of all aspects of what I am suggesting, but eliminating a t-case, trans, driveshafts, probably starter, probably alternator, there are significant cost savings there that could be put to offsetting increased costs.

Why valve issues? Don't get me wrong I am not against DI, but why use it when you can do the same or better without it. Think user serviceable vs having to take it to the dealer.
It creates a huge amount of build up on the back of the exhaust valves, especially when one uses ************ fuel all the time. I have seen dozens of valves that the back side looks like the mount Whitney of carbon.

I think it's intake valves. Exhaust are easy to clean: Braaaaaaaaaaaaaap. On a dyno or up a long hill.

This engine and the big gm engine, look like cake to clean up. I don't like di, but I could live with it, as long as the intake manifold is so easy to remove. The extra hp pump and injectors are my issue.

If an engine still had the tpi injectors, that could get us home when the di system failed........

As cool as this engine is, am I the only one who would be let down if the power is less than 500hp/500lb ft of torque? I know the torque curve is different, but the 3.5L Ecopoop in the Raptor is 450hp/500lb ft of torque.

Being honest, I’m also disappointed in the 6.4L Hemi in the HD Ram trucks because the bump in power from the 5.7L wasn’t that impressive. The 5.7L in my Power Wagon does the job, but I think the 4.56 gears help with getting stuff moving off the line. Somewhere between 2020 and 2022 I’m going to be truck shopping again, and I’ll be curious to see what Ford and Ram offer (the current interior on the Chevy/GMC does nothing for me so it’s not on the table). If Ford actually builds a Power Wagon fighter like the rumors claim, that would be an option.
