I've switched from a Tesla to a Ford F-150 Lightning. I miss the superior software experience and smoother ride quality of the Tesla, but I really appreciate a few standout features on the Lightning—like its full-size proportions, onboard power outlets, and the ability to illuminate the area around the truck with its lighting setup.

That said, if Scout Motors can combine those practical advantages into something even better, then I'd switch to the Scout Terra for that reason alone.

I'm skeptical about whether the added weight of the onboard generator (the "Harvester" range extender) will be worth it for me personally, but I could be proven wrong. I really need to get behind the wheel and drive it to see how it handles in real life.

From what I've seen so far, though, I'd lean toward the pure battery-electric Terra model that delivers a genuine 450–500 mile range without the generator—assuming they can actually achieve that kind of efficiency and capacity in the final production version (current projections are around 350 miles for the BEV, but I'm hopeful for improvements or a higher-spec option).


I know Scout hasn't promised 4-500 mile range in a battery only model so take this as feedback. You need to offer bigger battery like the Silverado EV so it does(it realistically gets 450 real miles). And you need to offer closer specs to the upcoming Lightning's 700 mile range for the harvester model.

I've seen way too many EV makers claim ranges like 320 miles only for real-world driving to knock off 20–40% depending on conditions—highway speeds, cold weather, towing, you name it. I've done extensive range testing myself with both my old Tesla and the current Ford F-150 Lightning, and while Ford does a somewhat better job of delivering closer to their EPA numbers in many scenarios, the gap is still there for trucks especially. I've driven without AC or heat and there's just no way to hit those numbers.

So when Scout announces their pure electric Terra with an estimated 350 miles of range (based on current projections for the ~120–130 kWh battery pack).. you'll have another EV truck that does 250 miles.

My straightforward advice: Match what the Chevrolet Silverado EV does with its higher-capacity battery options in the EV-only models. The Silverado EV offers packs up to around 205 kWh (in the Max Range versions), delivering EPA estimates of 440–493 miles depending on the trim—real-world results are often solid in the high 300s to low 400s for many owners under mixed conditions. No more of this sub-350-mile "false advertising" nonsense that leaves people stressed on longer trips.

Honestly, if an EV truck can genuinely deliver around 400 miles of usable real-world range (factoring in typical losses), that solves a ton of the range anxiety problems for most people—daily commutes, weekend getaways, even some road trips without constant charging stops. That's the benchmark Scout (or anyone else) should aim for in a pure BEV configuration.

FWIW, I also worry about the battery pack size, at least in the terms of actual useable range on the highway.

My Ioniq 9 has a 110kwh gross/107kwh useable battery pack size. And its EPA range rating is 320 miles. Now 120-130kwh is a fair bit larger (up to 18%). But The ioniq 9 seems like it should be substantially more aerodynamic than the Terra/Traveler. Is that extra battery capacity enough to overcome the efficiency difference at speed? No idea, thats the engineers job, and we'll sort of just have to wait and see.

Also, GM totally did achieve actually very long range (especially with the escalade IV, which is a bit more aero). And if scout did that, I really doubt it would be the standard battery size (as batteries are still quite expensive), so you probably wouldn't get a ~200kwh battery for $60k. I'm also not entirely sure I'd personally want that large of a battery (its just SOOO heavy), but would totally be ok with it as an option (and Id' be curious about the upcharge like at Rivian for their 180kwh battery).

Also, by the math, the harvester likely won't add much, if any weight. Batteries are heavy. Way heavier than people realize. Gasoline engines and 15 gallons of fuel are comparatively light.

The harvester is supposed to have a ~60-65kwh smaller battery than the BEV. If that battery is a NMC battery, that reduction in size is going to drop the vehicles weight by ~700-1000lbs. And a small 4 cylinder engine (1.5 - 2L) + 15 gallons of fuel, is likely going to weigh somewhere in the realm of 350-450lbs.

Now, the distribution of weight could be different with the harvester, which is theorized why it affects the towing rating of the vehicle. But from all I can tell so far, I'd actually expect the harvester to be the same weight, or slightly lighter.

I'd be sweating trying to stretch 200 miles out of my Tesla (even though it was rated for around 320 miles EPA). I drove it everywhere—mixed city, back roads, highways.

I'm pretty concerned about how the Scout Terra will actually perform and handle on the road. My previous RAV4 Hybrid felt like driving a heavy loaf of bread compared to the gas-only RAV4—way more sluggish steering and overall heft from the added battery weight and electric components.

Given that the Scout's range-extended (Harvester) version reportedly drops towing capacity significantly (potentially to around half of the pure EV's projected 10,000+ lbs for the Terra) and adds about a full second to 0-60 acceleration (BEV around 3.5 seconds vs. EREV closer to 4.5 seconds), I'm leaning hard toward the pure EV-only option now.

The trade-offs with the generator just don't seem worth it for my needs, especially if it compromises payload, towing, or that instant torque feel.

The Chevrolet Silverado EV is a weird one in a good way—I've seen reports where it actually exceeds its EPA numbers in some real-world tests (like highway or controlled conditions pushing past 450-500 miles, and even wild efficiency runs hitting over 1,000 miles at ultra-low speeds). That's rare for any EV, especially a truck, and it's the kind of reliable, over-delivering performance I'd love to see from Scout if they're serious about competing.

I'm not sure this is such an outlier. Its SCIENCE.

I was once forced to drive at very low speed for a hundred miles on backroads during the last solar eclipse in my R1T... Felt like I could have driven for days without a charge in northern New England. Lost like 20% SOC over a hundred miles or something crazy like that.

Why? The biggest impacts on EV truck's range are as follows:
  1. Speed (via aerodynamic drag) - efficiency is inversely and non‑linearly related to velocity
  2. Aerodynamics
  3. Payload & mass
  4. Tires & rolling resistance
  5. Terrain
  6. Temperature & HVAC
  7. Driving behavior
But don't take my word for it.

It would still be interesting to see how they all stack up for the long range tests (I'd imagine the Silverado might pull ahead) I appreciate how the SEV exceeds GM's claimed performance. Most EV manufacturers boast about 300-mile ranges, but in real-world driving, they fall short. GM broke the mold by delivering something different, and that's exactly what I hope Scout achieves. It's also important to note.. that if you need to drive highway speeds then you aren't going to get the rated range.. but the GM will!

GM built a truck with a massive battery, so they will of course have a longer range.

Tesla takes a lot of heat from owners for bloating their range estimates - amongst other things...
This is what I am trying to impart ;p

*Scout has the oppertunity to not be a Tesla. They can do what GM did and actually surpass even what they said it could do. (Most of those EPA ratings are at slower speeds which are unrealistic)

I'm feeling quite confident that emulating Elon is not a pillar in Scout's strategy.

How many miles you get? I have heard that Rivian does a better job on that.
How many miles I can get depends on a LOT of variables: this depends on my tires and wheels (I have summers and winters), heat or cold, uphill or downhill, headwind or tailwind, snow or rain, HWY or backroad.

Just like any EV.

How many highway miles you get? 70 MPH. You can see from the video above, the only one that pulls it off is the SEV long range. The Rivian is close though. Only thing is we aren't going to drive to 0%.. So it's a bit unrealistic in that sense. That’s an important factor in my buying decision. I want a vehicle that performs as advertised. The old model of EV manufacturers overstating or misrepresenting range just isn’t acceptable anymore.

There are a fair number of places reviewing EV's like that.

The more premium brands seem to do quite well. BMW, Mercedes, Porsche, Audi.

But its not just those. And historically, Tesla has been particularly bad in this area. But they had a lawsuit against them a while ago IIRC, and they had to update/reduce the EPA ranges, and its a bit closer now.

I'll take a look. I saw a video on the Silverado EV and couldn't believe that it actually got more than what was advertised (that's when I took notice). That really stuck with me especially having range wars with my Tesla. I have experience with three vehicles, Model X/Y and Lighting. I observed the same behaviors across all three. You would have to not use AC or heat and drive like 50-60 if you ever hoped to make it anywhere close lol.
 
My optimal conditions type numbers come very close to Edmunds Test numbers, which aren't a straight 70MPH HWY run, but rather mimic more real-world day to day to day driving with a 60/40 (city/hwy) split done by two drivers in one day starting at 100% SOC:

How does Edmunds conduct its testing?​

Instrumented testing is at the core of every Edmunds rating and review. We drive hundreds of cars each year and take pride in our independent testing, and Edmunds is one of the few publications that still publishes proprietary testing numbers for the vehicles we rate and review. The data you see in Edmunds reviews (and much more data that doesn't make it online) was gathered by our team of experts, allowing us to verify whether claims, such as a 0 to 60 mph time, hold up to what a manufacturer states. We created the Edmunds EV Range Test as a way to compare estimates from the EPA and manufacturers with the results of actual driving in the real world.

The methodology​

As with our instrumented track testing, we aim to be as thorough and consistent as possible in conducting the Edmunds EV Range Test. The cars we test are new and have been purchased by Edmunds or supplied by an automaker. The night before a test, each vehicle is charged to 100% and tire pressures are adjusted to the manufacturer's settings. As with gas-powered cars, having your tires at the wrong pressure can affect efficiency.

The EPA's guidelines call for a vehicle to be tested in the default settings at startup. A vehicle may have more efficient drive modes available (such as Eco or Efficiency), and you may be able to adjust the level of regenerative braking, but if the vehicle doesn't default to these settings, they won't be used. We do things slightly differently.

Edmunds' standard practice is to use the most efficient drive mode available as long as it doesn't compromise safety or practical comfort levels, such as fully deactivating the climate control system, significantly reducing power for acceleration, or limiting a vehicle's highway speeds. We're not trying to achieve the best range possible; rather, we're testing how EVs perform in the real world. We test each vehicle with windows up and the climate control set to auto at 72 degrees. If there's a "driver only" setting for the climate control, we'll use that as well. We also set the regenerative braking to its maximum setting.

To measure speed, distances and more, we attach Racelogic VBOX data logging devices to each car. These are the same data loggers that we use for our track testing and our Edmunds U-Drags series. However, we've worked with Racelogic to develop a custom program specifically for the Edmunds EV Range Test, which allows us to better monitor progress in real time.

The VBOX utilizes GPS, GLONASS, Beidou, and Galileo satellite constellations to accurately track real-time speed, overall average speed, distance traveled, and display a readout of the amount of highway driving completed over the course of the test. The key with our custom program is that it allows us to make calculations on the fly regarding distance and speed. This means we can be consistent across all of our testing no matter the road or traffic conditions. If average speeds or highway percentages are off the mark, we can adjust our route to bring things in line.

While we also track distance using a vehicle's trip odometer, the numbers we publish are based on those from the VBOX, as there's often a slight disparity between the two. We also utilize sensors and warning lights within the VBOX to ensure that drivers don't accelerate or brake too aggressively while driving.

Every test starts and ends at the Edmunds office, but the route length is adapted to suit each vehicle while aiming for a mix of 60% city driving and 40% highway. The driving is done all in a single day, and for vehicles with an EPA-estimated range of over 300 miles, we often split the test between two drivers.

Each vehicle is driven until there's 10 miles of indicated range remaining. Those 10 miles are a safety buffer to ensure that drivers can make it back to the office without getting stranded. That remaining range is added to the total distance driven (as indicated by the VBOX) for our final range figure.
