- EV model affords 350 miles; greater battery could be detrimental
- EREV system will go 150 miles on battery, then 350 miles on gasoline
- Guarantees full system efficiency whether or not on battery or vary extender
- Rivian-based structure guarantees to maintain electrical vans “recent”
It’s been practically two years since Volkswagen’s Scout Motors electrical SUV model introduced a $2 billion South Carolina manufacturing unit and began to emerge from stealth mode. However it is going to be one other two years earlier than these fashions are due for his or her first deliveries.
Based mostly on the reveal of its Traveler SUV and Terra pickup in idea variations proven final fall, together with costs stated to start out beneath $60,000, and government feedback up to now, Scout has laid out a few of the fundamentals for the model.
Scout will, on one hand, provide a glance again to the previous: rugged EVs with squared-off styling impressed by the traditional Worldwide Harvester SUVs created from 1960 to 1980. It received’t be a ruse both, as Scout guarantees to construct unparalleled DIY, back-to-basics simplicity into these vans, with an strategy that makes them simple to restore your self.

However however these vans shall be backstopped by some modern parts, together with a totally new infotainment interface known as Neighborhood UX, plus a zonal structure and software-defined car foundation conceived by the brand new three way partnership between the VW Group and Rivian. That’s an thrilling level, and it opens up every kind of alternatives that might add complexity or simplify, relying on the top product.
Might Scout’s standout pairing of nuts and bolts and clicky buttons, crossed with the potential of satellite-data-delivered characteristic upgrades, assist make EVs in style with a brand new group, or will it’s the McDLT of electrical SUVs?
It seems like fairly the balancing act from a know-how and engineering perspective, and that’s why Inexperienced Automotive Stories checked in with Scout Motors chief know-how officer Burkhard Huhnke final month at CES. As these fashions push forward from the idea to the prototype stage, the CTO revealed numerous particulars in regards to the model, the vans, and the tech.

Scout: Trailblazing EV range-extender structure
From an engineering standpoint, the elephant within the room is that, amongst Volkswagen Group’s core passenger car manufacturers—VW, Audi, Porsche, Lamborghini, and Bentley, plus Seat, Škoda, and Cupra—Scout is trailblazing. There isn’t any present body-on-frame SUV and there’s by no means been an EV with a variety extender.
“It’s after all a possibility,” stated Huhnke. The CTO underscored that it’s the primary body-on-frame car within the group, the primary mannequin with the ladder-frame idea, and the primary such car with an EREV propulsion system (a plug-in collection hybrid system, to be dubbed Harvester). “Every part has been developed as a unit—platform—which has the chance as a versatile platform to be scaled, perhaps, sooner or later,” he stated.
“Our IP has been generated in-house,” stated Huhnke, in regards to the EREV system, referring to it as one other core competence for Scout. So the engine, the generator motor, and different parts will come from elsewhere within the VW Group, Huhnke verified, whereas Scout is managing all of it in a unified system.
“The operational technique, it’s utterly ours,” he elaborated. “We can’t construct an engine ourselves, however the vary extender itself is so charming; you’re utilizing a BEV structure beneath and simply carrying a form of DC charging system with you.”
Huhnke didn’t give any hints about what engine, or kind of engine, could be used right here from the huge VW Group components bin. However addressing a possible sore level—ask some former BMW i3 REx house owners—he assured that drivers would have the “full efficiency of the system” whether or not utilizing the battery or continuously charging from the vary extender. Based mostly on cutaways proven by Scout Motors, the vary extender shall be small, and can mount not beneath the hood however on the rear of the car, behind the rear axle and beneath the cargo ground—an strategy that can preserve the frunk however hopefully not impinge on off-road angles.

Why does Scout EV peg 350 miles of vary?
Why did Scout determine that 350 miles is sufficient for the BEV, whereas Rivian, as an example, pushes to 410 or 420 miles and the Chevy Silverado EV and Cadillac Escalade IQ push it out to 460 miles?
Put bluntly, it could be near the restrictions of what suits throughout the ladder body. However Scout additionally didn’t need to be seen in the identical firm as fashions just like the GMC Hummer EV, Huhnke let on. It’s a matter of protecting weight beneath management—which is what the EREV model achieves.
Cramming in additional batteries, Huhnke defined, could be detrimental. “You may improve the driving vary by including an increasing number of capability into the battery, and that’s rising the burden drastically,” he stated. “Or it’s maxed out by the prevailing area of the ladder body.”
Scout claiming 500 miles with in gasoline range-extender type
Huhnke stated that the EREV model—which Scout CEO Scott Keogh just lately stated extra prospects have been ordering due to vary nervousness—will ship an electrical driving vary of round 150 miles, then an extra 350 miles with the range-extender. “So in complete, 500 miles, that ought to be adequate; it’s a commerce off in between the burden equation and the capability of the battery.”
The one different absolutely electrical fashions that journey on such a setup—physique over ladder body—are the Ford F-150 Lightning and the Mercedes-Benz G-Class EV (or G580 with EQ Know-how, in Mercedes advertising parlance). The latter suits a 116-kwh battery pack contained in the body rails, whereas the Lightning suits as much as 131 kwh. Scout hasn’t stated what dimension its battery packs are, nevertheless it makes clear it didn’t need to go super-sized.
GM’s full-size electrical pickups and SUVs, as launched within the GMC Hummer EV, make use of a construction that mixes elements of body-on-frame and unibody development, counting on a thick battery pack to supply a few of the structural advantages of a body. However these fashions’ curb weights soar previous 9,000 kilos.

Scout EVs shall be off-roaders to the core
Scout can even want a brand new stage of traction and stability management methods catered to off-road conditions—and Hunke assured that these are taking type in-house along with chassis and propulsion improvement.
“We’re going to have an air suspension built-in as a suspension system itself (his emphasis),” stated Huhnke, which can permit new ranges of tuning and discount of noise, vibration, and harshness (NVH). And he says it’s how Scout reconciles this with off-roading that shall be one other core competence.
“We had determined to have this off-road functionality, and subsequently we determined to make use of a extra typical strategy on the chassis and propulsion system,” he stated. “Which means now we have one e-beam (an electrical motor integrated right into a stable axle), as an example, because the rear axle.”
How a lot of all of that is really being engineered by Scout Motors? Some improvement is going on inside Scout, plus “competence in-house to design, simulate, and run sturdiness testing,” defined Huhnke. “In fact we’re working along with suppliers. We can’t simply rent a whole crew; that doesn’t make sense.”

Optimizing for weight, aero, sustainability
What Scout is doing lots of in-house is optimizing, through a improvement path that’s been totally different than something the VW Group has made thus far, Huhnke defined. Improvement has emphasised the usage of AI and digital twins—one of many auto-industry tech buzzwords of the yr—permitting the crew to check structural particulars, design particulars, or engineering modifications beneath, in a means that wasn’t doable earlier than with out bodily prototypes.
“Combining the complete compute energy in 3D fashions with a mixed AI strategy offers us instantaneous outcomes for modifications in aerodynamics or construction,” stated Huhnke, including that having a brand new manufacturing unit and its increased ranges of accuracy will profit from this fantastic tuning.
On the best way from idea to production-bound prototypes, that’s been particularly helpful in reconciling the design from chief design officer Chris Benjamin’s crew with underbody airflow. Huhnke stated that it’ll additionally assist the crew obtain its focused high U.S. security scores from the NHTSA and the IIHS.
You received’t discover carbon fiber within the Scout vans, nor a lot aluminum. The Scout electrical vans comply with a “conventional supplies strategy,” stated Huhnke, however the optimization strategy and simulation is resulting in a severe weight discount. It made selections to emphasise metal partly based mostly on carbon footprint, he stated. “We’re rigorously going by the fabric checklist and optimizing from that standpoint,” stated Huhnke. “For those who speak about carbon fiber, it’s all the time interesting for use from a weight optimization perspective, however not from the sustainability perspective.”
Rivian and Volkswagen Group electrical structure and software program stack
Radically totally different, Rivian-based underpinnings
Whereas the body-on-frame and solid-axle underpinnings recommend a conservative strategy to those autos general, what’s beneath connecting parts shall be one of the vital modern layouts within the {industry}.
“With the brand new three way partnership between VW and Rivian, now we have an opportunity to make use of zonal structure as one of many first manufacturers, and that provides us the OTA alternative we all the time needed to have,” stated Huhnke. “So new options, new updates over a lifetime…we’ll maintain the vehicles recent.”
The CTO is referring to the adoption of Rivian’s zonal structure, which permits an unlimited discount of the variety of separate management models across the car, and a discount of the quantity of wiring, connectors, and different related items. With software-based controls for zones, it offers rather more flexibility to roll out modifications that might retune, refine, or redefine how a core element works—the dream of the software-defined car.
Scout has confirmed that its electrical vans will run on 800 volts, and be able to charging at as much as 350 kw—and that they might help some stage of bidirectional charging functionality. Altogether, which may make it extra superior in some elementary elements than Rivian’s present R1 lineup whereas additionally harnessing Rivian’s extra superior electronics structure. The VW Group pioneered 800-volt methods within the Porsche Taycan and Audi E-Tron GT, and it’s now in a rising group of PPE autos together with the Porsche Macan Electrical and Audi Q6 E-Tron.
Scout Traveler idea
However there are many particulars but to return. Scout will emphasize tactile buttons and controls and received’t bury objects in infotainment menus, Huhnke promised. But the Scout vans will be capable of each monitor car diagnostics and handle predictive upkeep with cloud-based companies, with push updates when required. It additionally plans to construct satellite tv for pc web into its vans, however Huhnke prompt that it’s nonetheless figuring out the right way to make {that a} seamless a part of the expertise.
Two years from now Scout will present a really totally different expertise versus Rivian fashions, and maybe a distinct expertise versus every other EVs in the marketplace. Whether or not or not it’s successful is determined by worth, specs, and extra, after all, however maybe extra so, whether or not truck varieties are charmed by this very authentic mixture of the previous and the long run.
