Subaru to Launch Software-Defined Vehicles in Late 2020s, Embracing Over-the-Air Upgrades

Subaru says it will roll out software-defined vehicles in the latter half of the 2020s, marking a shift toward cars whose features and performance can be improved after purchase through over-the-air software updates. The announcement signals the Japanese automaker’s intention to bring more of its product strategy in line with an industrywide move toward vehicles that rely as much on code as on mechanical engineering.

Alongside the plan for software-centric models, Subaru is preparing a major overhaul of how it develops and readies new cars for production. The company expects to shorten the time needed to create next-generation vehicles by about 40% by expanding the use of digital tools in design and validation.

In practice, that means Subaru aims to replace some traditionally physical processes—such as building multiple rounds of prototypes and conducting certain tests primarily on hardware—with more virtual development. By digitizing parts of engineering work and shifting more evaluation into simulations and other computer-based methods, Subaru believes it can accelerate iteration cycles and reach production-ready designs faster.

The strategy was highlighted as the company showcased a prototype electric vehicle, underscoring that the production revamp is tied to Subaru’s next wave of products, including EVs. Digital design and testing can be especially important for electrified vehicles, which integrate complex software, power electronics, and battery management systems and often require rapid refinements as technology evolves.

Subaru’s move to software-defined vehicles also reflects growing customer expectations that cars will improve over time, much like smartphones. Over-the-air updates can allow automakers to deliver new functions, refine existing features, address bugs, and enhance safety systems without requiring owners to visit dealerships. For manufacturers, the approach can reduce the need for model-year hardware changes to fix issues, potentially lowering costs and enabling quicker responses once vehicles are on the road.

Taken together, Subaru’s twin initiatives—software-defined platforms and a more digital development pipeline—suggest the company is trying to increase agility in a market where timelines are tightening and competition in electrification and connected services is intensifying.

Why it matters

If Subaru achieves a 40% reduction in development time, it could bring new models and improvements to market faster, affecting buyers waiting for updated safety, connectivity, and EV offerings. Software-defined vehicles with over-the-air updates may also change how owners experience upgrades and fixes, shifting more improvements into software rather than hardware. The next key question is how Subaru will implement these updates securely and reliably as it transitions to a more software-driven product lineup.
