- May consolidate 50+ ECUs typical in new EVs to just some
- Nets a 3-5% acquire in effectivity and vary, quicker charging
- Simplifies meeting, cuts weight, extends attain of OTA updates
- Karma Kaveya EV arriving in 2026 is constructed on Intel structure
The thought of the software-defined automobile is, it appears, a billion-dollar buzzword in right this moment’s auto {industry}.
Really, the cash’s on it. In November, Volkswagen—recognizing Rivian’s progress within the space—invested as much as $5.8 billion in a brand new three way partnership with the U.S. EV maker. The funding is geared toward creating each the electrical structure and the software program for what would possibly quantity to hundreds of thousands of next-generation software-defined automobiles (SDVs).
Whereas we wait and see what that partnership brings, there’s a widespread consensus amongst tech suppliers and automakers that SDVs are the long run for EVs and past—whereas few have supplied a concrete roadmap of how and after they intend to get there.
At CES in Las Vegas earlier this month, Intel stood out as an exception, for its unveiling of a complete, whole-vehicle SDV answer. It claims way more than over-the-air updates, and that it would make EVs not solely extra adaptive to wants but in addition extra environment friendly—with as much as a 5% acquire in EV vary and effectivity from its new software-defined structure plus a extra responsive driving expertise.
Karma Kaveya
Karma to be “residing improvement prototype” for Intel structure
That structure isn’t a far-out idea, and it might be put to the take a look at in lower than two years. The Intel whole-vehicle software-defined structure is because of be included on the Karma Kaveya, a 1,000-hp absolutely electrical all-wheel-drive coupe, with claimed 0-60 mph acceleration beneath 3.0 seconds, that’s slated for manufacturing in 2026.
“We predict that we have now the chance to be the very first producer to deploy a full ground-up true software-defined automobile structure,” stated Marques McCammon, at Intel Automotive’s CES presentation. “And we’ll try this with the Karma Kaveya; it’ll have the flexibility to have workloads redistributed, be up to date by way of the cloud, and it’ll function a platform for each Karma automobile going ahead.”
McCammon stated that the Karma EV will probably be “a residing improvement prototype for the broader {industry}, as we ally for the event, appearing as a improvement associate at scale.”
Revealed at CES was Intel’s Adaptive Management Unit (ACU), which claims to consolidate the management of car domains, purposes, and safety-critical capabilities all onto one central processing chip.

Extra than simply OTA updates, Intel simplifies {hardware}
Most trendy automobiles make use of a variety of separate controllers, every with their very own wiring and digital management unit (ECU), both as a part of a distributed method or a consolidated zonal method. Intel claims that with the ACU it could actually cut back total vitality demand from an EV’s battery pack by truly adapting the voltage degree for high-voltage programs in actual time, relying on the situations (like driving model).
Its technique, with a software-defined zonal controller, can freely shift workloads round. Tesla’s Sentry mode for automobile safety, for instance, runs on the in-cabin system right this moment and makes use of 40 to 50 watts continually, talked about Jack Weast, Intel’s VP and the overall supervisor of Intel Automotive, within the firm’s CES presentation earlier this month. However with a zonal platform it could actually run on just some watts, turning on the bigger system when there’s an intruder.
Or, famous Weast later, in case you’re at a protracted stoplight, some facets of active-safety programs won’t have to be powered up.
“The best way that we have a look at it’s to consider an information middle; you get all these huge racks of computing however you’ll be able to actually use software program to activate one rack or the opposite, transfer workloads forwards and backwards,” defined McCammon to Inexperienced Automobile Studies as we took within the present.
The Karma CEO famous the parallels between the concept and one {industry} normal that began with Intel and developed from not simply communication to scalable energy and voltage—that of the USB port.

This form of dynamic variable voltage scaling may need been used on parts of the EV platform beforehand, however increasing the idea to your entire automobile is one thing new.
“That is what we’ve been doing in PC platforms for 20 years,” summed Weast within the CES presentation.
It will be a welcome change at this level. At present’s automobiles might be nightmares to service, not to mention assemble—primarily rats’ nests of disparate management items, situated across the automobile and infrequently working at totally different voltages and ranges of connectivity, leaving some programs able to over-the-air updates and others not. Greater than 50 ECUs isn’t unusual in new automobiles, and a few automobiles have greater than 100.
Intel’s answer may help “a number of topologies,” as a part of a whole-vehicle structure, it claims, and it might be the following step—or one of many subsequent steps—in a quiet revolution in how automobiles are conceived, constructed, and upgraded.
Intel Automotive SDV undertaking
Constructing on Tesla and Rivian, or leapfrogging it?
Business suppliers have some catching-up, measuring-up, and coordinating on requirements to do, whereas there’s actually potential to innovate. However a few of this duty has been within the arms of automakers.
Shifting to a wiring-saving “zonal” structure, with zones primarily based on bodily location reasonably than particular duties, is without doubt one of the keys. So is shifting to software program controls for these zones and the parts inside them.
Tesla led greater than a decade in the past by making use of the software-based, over-the-air-update mannequin of smartphones to its automobiles—and making use of the zonal method—converging on the concept of programs that might be readily upgraded or options that is likely to be enabled by way of software program.
Nio, amongst others, has additionally used a zonal method. Rivian stays an {industry} darling of this transformation, and it managed in a rethink of its structure that arrived final yr within the 2025 Rivian R1S and R1T to consolidate an already-neat 17 ECUs down to simply seven, slicing 1.6 miles of copper wiring from the automobile, serving to optimize effectivity and simplifying the provision chain.
Underneath VW’s funding in Rivian, it’ll license that zonal design and permit future collaboration between the 2 corporations. The method may result in extra simply upgradable automobiles which may price much less to construct and in addition would possibly higher deal with {hardware} modifications over time.
Intel Adaptive Management Unit for software-defined automobiles
Though there’s no full manufacturing automobile with Intel’s method but, it claims an 80% discount in ECUs, a 60% discount in wiring harness size, and a 35% or extra discount in energy consumption. Additional, Intel says that the method means decrease automobile element prices, permitting a smaller motor and battery pack—and lower-cost EV platforms total.
All this stated, it’s unclear whether or not Intel’s answer is merely treading water amongst tomorrow’s EVs or swimming laps round them. Practically each automaker by now understands the need to simplify with the intention to compete. Ford CEO Jim Farley, as an example, stated in 2023 that its next-generation EVs will probably be “radically simplified,” with a brand new electrical structure that’s absolutely software program updatable.

Karma’s EV inverter is a key piece
Again to the vitality benefits, Intel says that its method, together with an influence administration system-on-chip (SoC), helps maximize effectivity for inverters, chargers, and converters. System-wide, the method recovers as much as 40% of what would in any other case be powertrain-system vitality losses—netting a 3-5% acquire in effectivity and vary, by WLTP-cycle testing, together with quicker charging and “a extra responsive driving expertise.”
The inverter is without doubt one of the keys to that, and California’s Karma Automotive developed an inverter unit that’s meant to be a part of Intel’s whole-vehicle answer. The silicon carbide inverter is Karma’s personal mental property, confirmed Marques McCammon to Inexperienced Automobile Studies, and prone to be made in Michigan, nevertheless it’s co-branded with Intel.

By now you is likely to be questioning: Why is the CEO of the California-based area of interest, low-volume luxurious automobile maker, which is finest recognized for reviving and refining automobiles and programs derived from the primary Fisker Automotive, speaking industry-altering tech in such a deep method?
It stems from a protracted partnership when he was a administration counterpart at Wind River programs—McCammon on the software program aspect, Weast on the {hardware} aspect.
“We had a imaginative and prescient then of what a software-enabled, or software-defined automobile was going to be,” McCammon defined to GCR. “However once we thought this up, we all the time wanted somebody to go first.”
Quick ahead a decade, to a few yr in the past, and Intel had simply acquired Silicon Mobility, which McCammon stated was a turning level.
Intel Automotive EV interface
“We stated, the place can we begin? Everyone’s targeted on the cabin, however actually vitality administration, utilization, and effectivity is within the powertrain domains.”
Karma had already been creating its personal inverter, its personal powertrain area management unit, and a chipset, McCammon defined, however Intel and Silicon Mobility delivered to the desk “added a degree of software program programmability right into a system that’s often very fastened.”
McCammon defined that Karma primarily now it has a programmable API between motor and {hardware}—one thing most different trendy EVs don’t have. “We had been already engaged on it for our subsequent inverter, for our subsequent technology merchandise,” he stated. “It was a pure match.”
“The inverter is one piece of it—this half we’re speaking about right this moment— however we’re engaged on a lot, way more,” added McCammon.
