- EV model presents 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 vehicles “recent”
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.
Primarily based on the reveal of its Traveler SUV and Terra pickup in idea variations proven final fall, together with costs stated to begin beneath $60,000, and government feedback up to now, Scout has laid out among 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 vehicles, with an strategy that makes them straightforward to restore your self.

However alternatively these vehicles will likely be backstopped by some modern components, together with a totally new infotainment interface referred to as Group UX, plus a zonal structure and software-defined automobile 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 would add complexity or simplify, relying on the tip product.
May Scout’s standout pairing of nuts and bolts and clicky buttons, crossed with the potential of satellite-data-delivered characteristic upgrades, assist make EVs standard 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 Studies 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 varied particulars concerning the model, the vehicles, 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 automobile 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 in fact a possibility,” stated Huhnke. The CTO underscored that it’s the primary body-on-frame automobile within the group, the primary mannequin with the ladder-frame idea, and the primary such automobile with an EREV propulsion system (a plug-in collection hybrid system, to be dubbed Harvester). “All the things has been developed as a unit—platform—which has the chance as a versatile platform to be scaled, possibly, 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 utterly 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 sort of DC charging system with you.”
Huhnke didn’t give any hints about what engine, or sort of engine, could be used right here from the huge VW Group elements bin. However addressing a possible sore level—ask some former BMW i3 REx homeowners—he assured that drivers would have the “full efficiency of the system” whether or not utilizing the battery or always charging from the vary extender. Primarily based on cutaways proven by Scout Motors, the vary extender will likely be small, and can mount not beneath the hood however on the rear of the automobile, 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 resolve that 350 miles is sufficient for the BEV, whereas Rivian, as an illustration, pushes to 410 or 420 miles and the Chevy Silverado EV and Cadillac Escalade IQ push it out to 460 miles?
Put bluntly, it might be near the constraints of what matches throughout 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 beneath 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 rising the load drastically,” he stated. “Or it’s maxed out by the present area 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 not too long ago stated extra clients 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 load equation and the capability of the battery.”
The one different totally electrical fashions that experience 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 dimension its battery packs are, however 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 facets of body-on-frame and unibody development, counting on a thick battery pack to offer among the structural advantages of a body. However these fashions’ curb weights soar previous 9,000 kilos.

Scout EVs will likely be off-roaders to the core
Scout will even want a brand new degree of traction and stability management techniques catered to off-road conditions—and Huhnke 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 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 will likely be one other core competence.
“We had determined to have this off-road functionality, and subsequently we determined to make use of a extra standard strategy on the chassis and propulsion system,” he stated. “Meaning now we have one e-beam (an electrical motor integrated right into a strong axle), as an illustration, because the rear axle.”
How a lot of all of that is really 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 crew; that doesn’t make sense.”
Scout Terra and Traveler ideas
Optimizing for weight, aero, sustainability
What Scout is doing loads of in-house is optimizing, by way of a improvement path that’s been totally different than something the VW Group has made thus far, Huhnke defined. Growth 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 approach that wasn’t attainable earlier than with out bodily prototypes.
“Combining the total compute energy in 3D fashions with a mixed AI strategy provides us immediate outcomes for modifications in aerodynamics or construction,” stated Huhnke, including that having a brand new manufacturing unit and its increased ranges of accuracy will take advantage of this positive tuning.
On the way in which 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’s going to additionally assist the crew obtain its focused prime U.S. security scores from the NHTSA and the IIHS.
You gained’t discover carbon fiber within the Scout vehicles, nor a lot aluminum. The Scout electrical vehicles 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 fastidiously going by the fabric record and optimizing from that standpoint,” stated Huhnke. “In the event you discuss carbon fiber, it’s at all times 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 counsel a conservative strategy to those autos general, what’s beneath connecting elements will likely be probably the most 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 at all times wished to have,” stated Huhnke. “So new options, new updates over a lifetime…we’ll preserve the automobiles recent.”
The CTO is referring to the adoption of Rivian’s zonal structure, which permits an unlimited discount of the variety of separate management items across the automobile, and a discount of the quantity of wiring, connectors, and different related items. With software-based controls for zones, it provides far more flexibility to roll out modifications that would retune, refine, or redefine how a core element works—the dream of the software-defined automobile.
Scout has confirmed that its electrical vehicles will run on 800 volts, and be able to charging at as much as 350 kw—and that they might assist some degree of bidirectional charging functionality. Altogether, that may make it extra superior in some basic facets than Rivian’s present R1 lineup whereas additionally harnessing Rivian’s extra superior electronics structure. The VW Group pioneered 800-volt techniques 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 come back. Scout will emphasize tactile buttons and controls and gained’t bury gadgets in infotainment menus, Huhnke promised. But the Scout vehicles will be capable to each monitor automobile 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 vehicles, however Huhnke instructed that it’s nonetheless understanding methods 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 unique expertise versus every other EVs available on the market. Whether or not or not it’s a success will depend on worth, specs, and extra, in fact, however maybe extra so, whether or not truck sorts are charmed by this very unique mixture of the previous and the longer term.
