- EV model gives 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 facility 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.
Primarily based on the reveal of its Traveler SUV and Terra pickup in idea variations proven final fall, together with costs mentioned to start out underneath $60,000, and govt feedback so far, Scout has laid out a few 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 received’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 then again these vehicles can be backstopped by some modern parts, together with a totally new infotainment interface referred to 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 function upgrades, assist make EVs common with a brand new group, or will or not it’s the McDLT of electrical SUVs?
It appears like fairly the balancing act from a expertise and engineering perspective, and that’s why Inexperienced Automotive 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 in regards to 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 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 in fact a chance,” mentioned 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 little thing has been developed as a unit—platform—which has the chance as a versatile platform to be scaled, perhaps, sooner or later,” he mentioned.
“Our IP has been generated in-house,” mentioned 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, is likely to 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 can be small, and can mount not underneath the hood however on the rear of the car, behind the rear axle and underneath the cargo ground—an strategy that may 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 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 matches inside 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 underneath management—which is what the EREV model achieves.
Cramming in additional batteries, Huhnke defined, can be detrimental. “You possibly can improve the driving vary by including increasingly capability into the battery, and that’s growing the load drastically,” he mentioned. “Or it’s maxed out by the present area of the ladder body.”
Scout claiming 500 miles with in gasoline range-extender kind
Huhnke mentioned that the EREV model—which Scout CEO Scott Keogh just lately mentioned extra prospects have been ordering due to vary nervousness—will ship an electrical driving vary of round 150 miles, then a further 350 miles with the range-extender. “So in whole, 500 miles, that must be adequate; it’s a commerce off in between the load equation and the capability of the battery.”
The one different absolutely 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 Expertise, 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 mentioned what measurement its battery packs are, however 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 facets of body-on-frame and unibody building, counting on a thick battery pack to offer a few 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 also want a brand new stage of traction and stability management methods catered to off-road conditions—and Hunke assured that these are taking kind in-house along with chassis and propulsion growth.
“We’re going to have an air suspension built-in as a suspension system itself (his emphasis),” mentioned 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 due to this fact we determined to make use of a extra typical strategy on the chassis and propulsion system,” he mentioned. “Meaning we’ve 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 actually being engineered by Scout Motors? Some growth 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 group; that doesn’t make sense.”
Scout Terra and Traveler ideas
Optimizing for weight, aero, sustainability
What Scout is doing a number of in-house is optimizing, through a growth path that’s been completely different than something the VW Group has made to date, Huhnke defined. Growth has emphasised the usage of AI and digital twins—one of many auto-industry tech buzzwords of the 12 months—permitting the group 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 offers us immediate outcomes for modifications in aerodynamics or construction,” mentioned Huhnke, including that having a brand new manufacturing facility and its larger ranges of accuracy will benefit from this tremendous 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 group with underbody airflow. Huhnke mentioned that it’ll additionally assist the group obtain its focused prime U.S. security scores from the NHTSA and the IIHS.
You received’t discover carbon fiber within the Scout vehicles, nor a lot aluminum. The Scout electrical vehicles comply with a “conventional supplies strategy,” mentioned Huhnke, however the optimization strategy and simulation is resulting in a severe weight discount. It made selections to emphasise metal partly primarily based on carbon footprint, he mentioned. “We’re fastidiously going by means of the fabric listing and optimizing from that standpoint,” mentioned Huhnke. “Should 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 completely 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 parts can be probably the most modern layouts within the {industry}.
“With the brand new three way partnership between VW and Rivian, we’ve 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 needed to have,” mentioned 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 way more flexibility to roll out modifications that would retune, refine, or redefine how a core part works—the dream of the software-defined car.
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’d help some stage of bidirectional charging functionality. Altogether, which may make it extra superior in some elementary facets 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 vehicles 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 vehicles, however Huhnke advised that it’s nonetheless figuring out 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 unique expertise versus some other EVs available on the market. Whether or not or not it’s successful is dependent upon worth, specs, and extra, in fact, however maybe extra so, whether or not truck varieties are charmed by this very authentic mixture of the previous and the longer term.
