Scout concepts on Jay Leno’s Garage

[CP1@scoutmotors]

I like the feedback everyone is providing on the segment. Some good.... Some bad.

Like Jamie explained these are one off concept vehicles. The only 2 in existence currently. They are not "Early prototypes" and were not built at a plant. All the parts on these vehicles are one of a kind. If something breaks, we have to go back and make a new part from scratch or try and repair the part.

I am one of two here at Scout Motors that are responsible for these vehicles.

Was it nerve racking knowing that it was going on a joyride out of nowhere?

Very. Although Jay was very friendly to them. But like Jamie stated, the propulsion of these vehicles was designed for loading and unloading purposes only. And to get them into position for a show.

We haven't said anything officially at this point. This is still fluid and being optimized, so lets see as we get further along in the process.

Thank you

Hard to follow all the points in the video but did he imply that harvester is 'gas and go'?

I can only make guesses. But in EV, you will run most of the battery down before you get a warning - which could in theory put you into a slight limp position if you go to hybrid and still want to exceed the steady state. In Hybrid, it will either have a set point to turn on the harvester, or calculate it based on how hard you are driving - but my bet is to maintain maxim combined range. In performance mode, the harvester will turn on quite early so conserve EV only to times when you exceed the steady state - as on long high speed road trips you might get multiple tanks to the charge (but if you are exceeding steady state, eventually you will need to charge - even if it is off the harvester).

My guesses are a bit more random when it comes to towing. I have no clue if the 5k limit is due to a powertrain issue caused by the compromises to get the harvester in at a reasonable cost - or if they are due to the increased load massively changing the Steady State speed.
---
Pulling from memory - a 140kwh battery will give us 350 miles - 2.5 miles/kw. Using that as a base - then a 60kwh battery would do 150 miles. Now assuming the harvester can do 350 miles at the same speed (assuming 70mph) - then the generator would be running 5hrs and generating 140kw - so 28kw generator. I think these are all reasonable numbers. If towing 1/2's ev range, then I think it is safe to assume that it will do the same with the Harvester. If you are using 28kw/h to maintain a steady state at 70mph, if you double the load, the battery will need to be kicking in 28kw/h to maintain the same speed while towing. The BEV will give you a 175 mile range, but the battery in the harvester will run out of amp hours after 2hrs - so it will only give you 140 miles of range (even with the harvester running the entire time). It is not something I would really want to advertise-especially if you are selling a cure to range anxiety.

Now that extended calculation is flawed in many ways. It is assuming the Harvester is steady state at 70mph unloaded. If it is larger than this and the steady state is with a 5k tow - then you might get a few more miles off the smaller EREV battery if you exceed the weight or speed. It is also assuming you loose 1/2 the range with a 5k tow - which might be excessive. Perhaps you only loose that much with a 10k tow. Honestly, need a lot more info for anyone to determent if the trade offs work for them.

just a quick google. Normal temps (not freezing), owners have posted a 1/2 range loss with a 10k trailer and 1k of vehicle payload (gear and passengers). If we use these losses - then the 5k tow should look better. Second google - wind drag is probably as big of factor as weight. Cybertruck ranges with a lighter camper still sucked kw's.

Yes, aerodynamic drag goes up with the square of the speed, it is the bigger factor on flat ground. Gravity potential energy is linear with elevation change so weight matters when climbing hills.

Thank you

Thanks Jamie

I should have said GPE is linear with both mass and distance. Twice the weight over the same height takes twice the energy, same weight over twice the height takes twice the energy.

I appreciate everyone’s technical discussions. Honestly for me I look at it and just love it. That’s where it starts with me. Every time I see it my heart skips a bit and I tell my husband it’s just so pretty. At this point I’m down to three things. Can I afford it, does it get me where I need to go and does it look like the prototype. As my husband says you know you picked the right car when you walk away from it in the parking lot and turn around to stare at it for a minute thinking damn that looks good. That’s where I am now. I look at it and know it’s my truck because damn it looks good.

Yes and No. they are keeping a-lot of information under wrap right now which is pretty good on them. The Harvester is very new to Scout and obviously everyone here. The engineers seem to be throwing out under estimated numbers to keep all of our mouths shut. LOL

Thanks for sharing your point of view and great work keeping them together and fresh

Yes

And depending on what you expect for gas and go. The battery needs some charge to provide max power for acceleration and climbing. But you can drive around town or back and forth across Kansas forever just buying gas as needed. The generator wlll maintain the battery.

 

[THil08]

You could tell Scott was throwing numbers out that were reasonable, but they were to really stop Jay from asking questions lol.

Yeah my guess is it would maintain under normal/reasonable driving conditions then if you want to fully charge you could let it run while the vehicle is parked. Of course I'm sure it'll be way more expensive to charge/operate the car this way vs plugging the thing in.
