- EV model affords 350 miles; greater battery can 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 “contemporary”
It’s been almost 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 will likely 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 begin below $60,000, and government feedback up to now, Scout has laid out a number of the fundamentals for the model.
Scout will, on one hand, supply a glance again to the previous: rugged EVs with squared-off styling impressed by the basic Worldwide Harvester SUVs constructed from 1960 to 1980. It gained’t be a ruse both, as Scout guarantees to construct unparalleled DIY, back-to-basics simplicity into these vans, with an method that makes them straightforward to restore your self.

However however these vans can be backstopped by some modern components, together with a very new infotainment interface known as Group 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 all types of alternatives that would add complexity or simplify, relying on the tip 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 common with a brand new group, or will it’s the McDLT of electrical SUVs?
It seems like fairly the balancing act from a expertise and engineering perspective, and that’s why Inexperienced Automobile Reviews checked in with Scout Motors chief expertise officer Burkhard Huhnke final month at CES. As these fashions push forward from the idea to the prototype stage, the CTO revealed numerous particulars concerning the model, the vans, and the tech.

Scout: Trailblazing EV range-extender format
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 a present body-on-frame SUV and there’s by no means been an EV with a variety extender.
“It’s after all a chance,” 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 thing 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, concerning the EREV system, referring to it as one other core competence for Scout. So the engine, the generator motor, and different elements 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 fully ours,” he elaborated. “We can not 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, may 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 can be small, and can mount not below the hood however on the rear of the car, behind the rear axle and below the cargo ground—an method that may keep the frunk however hopefully not impinge on off-road angles.

Why does Scout EV peg 350 miles of vary?
Why did Scout resolve 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 constraints of what matches inside the ladder body. However Scout additionally didn’t wish to be seen in the identical firm as fashions just like the GMC Hummer EV, Huhnke let on. It’s a matter of maintaining weight below management—which is what the EREV model achieves.
Cramming in additional batteries, Huhnke defined, can be detrimental. “You’ll be able to improve the driving vary by including increasingly capability into the battery, and that’s growing the burden drastically,” he stated. “Or it’s maxed out by the prevailing house of the ladder body.”
Scout claiming 500 miles with in gasoline range-extender kind
Huhnke stated that the EREV model—which Scout CEO Scott Keogh lately stated extra prospects had 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 whole, 500 miles, that ought to be enough; it’s a commerce off in between the burden equation and the capability of the battery.”
The one different totally electrical fashions that trip 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 and marketing parlance). The latter matches a 116-kwh battery pack contained in the body rails, whereas the Lightning matches as much as 131 kwh. Scout hasn’t stated what measurement its battery packs are, nevertheless it makes clear it didn’t wish 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 points of body-on-frame and unibody development, counting on a thick battery pack to offer a number of the structural advantages of a body. However these fashions’ curb weights soar previous 9,000 kilos.

Scout EVs can be off-roaders to the core
Scout may even want a brand new stage of traction and stability management programs catered to off-road conditions—and Hunke assured that these are taking kind 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 is able to enable 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 can 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 method on the chassis and propulsion system,” he stated. “Which means we’ve got one e-beam (an electrical motor included right into a stable axle), as an example, because the rear axle.”
How a lot of all of that is actually being engineered by Scout Motors? Some improvement is occurring 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 not simply rent a complete staff; that doesn’t make sense.”

Optimizing for weight, aero, sustainability
What Scout is doing a variety of in-house is optimizing, by way of a improvement path that’s been completely different than something the VW Group has made to date, Huhnke defined. Improvement has emphasised using AI and digital twins—one of many auto-industry tech buzzwords of the yr—permitting the staff to check structural particulars, design particulars, or engineering modifications beneath, in a approach that wasn’t potential earlier than with out bodily prototypes.
“Combining the complete compute energy in 3D fashions with a mixed AI method offers us instantaneous outcomes for modifications in aerodynamics or construction,” stated Huhnke, including that having a brand new manufacturing unit and its greater ranges of accuracy will benefit from this positive 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 staff with underbody airflow. Huhnke stated that it’s going to additionally assist the staff obtain its focused high U.S. security scores from the NHTSA and the IIHS.
You gained’t discover carbon fiber within the Scout vans, nor a lot aluminum. The Scout electrical vans comply with a “conventional supplies method,” stated Huhnke, however the optimization method and simulation is resulting in a severe weight discount. It made choices to emphasise metal partly based mostly on carbon footprint, he stated. “We’re fastidiously going via the fabric listing and optimizing from that standpoint,” stated Huhnke. “Should you discuss 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 completely different, Rivian-based underpinnings
Whereas the body-on-frame and solid-axle underpinnings recommend a conservative method to those autos general, what’s beneath connecting elements can be one of the modern layouts within the {industry}.
“With the brand new three way partnership between VW and Rivian, we’ve got an opportunity to make use of zonal structure as one of many first manufacturers, and that offers us the OTA alternative we all the time wished to have,” stated Huhnke. “So new options, new updates over a lifetime…we’ll hold the automobiles contemporary.”
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 would 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’d help some stage of bidirectional charging functionality. Altogether, which may make it extra superior in some elementary points than Rivian’s present R1 lineup whereas additionally harnessing Rivian’s extra superior electronics structure. The VW Group pioneered 800-volt programs 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 gained’t bury objects in infotainment menus, Huhnke promised. But the Scout vans will be capable to 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 instructed that it’s nonetheless understanding the best way to make {that a} seamless a part of the expertise.
Two years from now Scout will present a really completely different expertise versus Rivian fashions, and maybe a special expertise versus another EVs in the marketplace. Whether or not or not it’s successful will depend on value, specs, and extra, after all, however maybe extra so, whether or not truck sorts are charmed by this very unique mixture of the previous and the long run.
