Yeah Joseph beat you to it a few days ago on the Scottsdale photos thread. No worries!

I wondering how many, if any, have decided to switch back to wanting a full BEV after seeing how crazy the rear mounted engine idea is. I’m not a fan for sure. Bring on the batteries 🔋
With the removal of purchase subsidies, the removal of government support for a charging infrastructure, and the need for the ability to take long trips, the Range Extender is the only way I would buy this vehicle. A off-road vehicle with 350 miles of EV range and the need for electric charge is a non-starter without an on board generator. Where am I going to charge once I arrive at the wilderness! The Scout is highly capable off road. But there's no charging stations in remote areas. What am I going to run on? Might as well keep my Bronco. Need ⛽

I agree, need some form of charging/generator out in the wild but my guess is we are rare use case. Most ppl will mall crawl/pavement princess this vehicle, like all other capable vehicle in this class. Sad honestly, but is what it is.

I'm not a fan of the rear overhang and this may significantly cut departure angles, and would gladly swap a frunk for a generator in its stead. I'm ok if they take their time in designing this right, release the BEV first to get the name out there and ride the hype wave!

Yes, I would agree that careful thought needs to be put into the placement of the gas tank and the engine & generator. Hanging it off the back like a Volkswagen Bug doesn't seem ideal. Also, mechanic access is necessary for maintenance & repairs on a gasoline engine, by that VW network that's being cut out of sales! As you say, the frunk may be the best location, including for service access.

I do not believe we'll see a pure BEV, at this point, Scout has already announced the Range Extended SUV as the first vehicle to be produced. This is because, based on our pre-orders, 70% of early adopting reservations are for the SUV with ⛽ Range Extender engine. I can't imagine that changing. Especially in the current political environment, which makes propulsion choices purely a free-market decision.

If anything, Scout should consider a gas-griven vehicle. If not, the range extending version is the way to go.

The way battery tech is advancing, three years from now range extenders will be a thing of the past. They might produce one generation of the range extender. It will soon be a dinosaur!
Just my thoughts!

Depends on your use case and I disagree. For those that take their scouts out you can't charge in the wild. Hybrid systems will be useful if they can design them correctly.

Count me as one of those who want to use the Scout to drive to campsites far from the nearest charging station. That's kind of the whole idea. With vampire drain during three or four days at the campsite, an EV is going to need a range of over 400 miles for me to feel comfortable taking it way out into the middle of nowhere.

A trail-competent PHEV or range-extended EV will fill the bill. I'll withhold judgment on the Scout's design until it's a rolling reality.

I am talking batteries with 600+ miles of range that recharge from 10-90% in 10 min, with smaller and lighter packaging. This sector is moving incredibly fast. 3 years is a very long time

I hope you are correct! If that chemistry happens, they will also be able to invent solar charging cells on the rooftop or hood that can partly charge the battery as well!

I'd like to see integrated solar. Not so much for driving, but for refrigeration . . . Every little bit helps. I've been running a 12v frig in my Bronco for 3 years now.

I hope that happens. Battery chemistry is only the first hurdle. They have to be mass-produced and affordable. In three years we will know

I’ve been on a lot of car forums and what I didn’t know or expect was the huge amount of forum members here that are off-roaders or campsite warriors. I’ve never been “that guy”, so it’s been a learning experience being here and realizing that my use case is in the tiny minority. My Scout, if it comes to fruition, will definitely be as No Remorse’s “pavement princess” :involve: description. Just like my Defender, it’s never going to be rolling out into the wild for some campsite bedbugs.

Completely understand those who want to range extender for those under the stars moments in the Toolies. I’m just looking for a bad-ass looking AWD Scout type rig with hopefully the awesome utilitarian interior like the Defender has. Which is the biggest reason why I bought it. It’s been 12 years of owning an EV or EREV and have yet to pay for charging anywhere.

Hopefully this isn't a duplicate somewhere as I looked around before posting...

https://carbuzz.com/scout-harvester-range-extender-patent/
Just as the “Note” At the bottom of that article says,

“Patent filings do not guarantee the use of such technology in future vehicles and are often used exclusively as a means of protecting intellectual property. Such a filing cannot be construed as confirmation of production intent.”

This could be nothing, or even a way to throw off competition. What is really odd is the highly detailed drawings. You just don’t see that in patents, that is, grayscale type of drawings. Patent drawings are usually distinct black and white line drawings. The whole patent process is ALL about claims and wording. The patent claims go with basically a descriptive explanation of how to build it, as in leg bone to foot bone.

The very descriptive stories behind patents has largely disappeared as they just don’t mean anything - the claims say it all. I’ve done a bunch of patent drawings and was discouraged by my patent attorney to not do any such grayscale type of illustration. So this is why these drawings are weird to me. Could be total smoke and mirrors.

And there could be tons of claims just for poops and giggles. When the claims become serious (examiners send back first response to the claims), then Scout could fight for a claim or forget it. But these first patent submissions could be solely for casting a large net to get the widest moat on something they’re making and they’re just covering the widest possible “thought bench” to work off of, and nail down final designs and hardcore sought after claims later.
