Subaru prepares software-defined vehicles: OTA updates, an AMD co-developed chip and 40% faster development
Subaru will launch software-defined vehicles in the second half of the decade. A new integrated ECU with a chip co-developed with AMD will take over-the-air updates, while digital crash simulation cuts development time by about 40%.
Subaru is moving into the era of software-defined vehicles (SDVs). At its research centre in Sano, Tochigi Prefecture, the Japanese carmaker laid out plans for models that will receive over-the-air (OTA) updates in the second half of this decade, "Reuters" reports. Subaru also showed how digital simulation cuts the time needed to develop a car by about 40%.
A new "brain" with an AMD co-developed chip
According to "Reuters", the plan centres on a newly developed integrated ECU that will be rolled out gradually across the line-up. Its core chip was developed jointly with AMD. Through OTA updates, Subaru aims to improve driver-assistance, automated-driving and vehicle performance functions. The electronic platforms will be shared across electric, hybrid and petrol models.
The partnerships are on the official record. In April 2024, Subaru announced it was working with AMD on a chip for next-generation EyeSight. In March 2026, it added Infineon's AURIX TC4x microcontroller for the ECU that links EyeSight with vehicle motion control, including all-wheel drive.
Fewer physical tests, more simulation
"NHK World" reports that much of Subaru's crash testing will be replaced by digital simulation built on data from past tests, with results close to those of real crashes. The roughly 40% saving comes from simulation and from Subaru engineers now working side by side with partner-company staff. Design, testing and production preparation run in parallel, "Reuters" notes.
Speaking to "NHK World", Executive Officer Takatomo Watamori said it is very encouraging that digital technology makes much faster development possible. He added that Subaru will keep refining safety, driving enjoyment and development flexibility.
Practical, not complicated
According to "Jiji Press", Subaru wants its software-defined vehicles to be easy to use and affordably priced, rather than packed with extremely advanced features for their own sake. Costs will be kept in check by optimising the system's functions.

What it means for drivers
- Cars that get better over time: future models will be able to gain new assistance features and performance tweaks over the air.
- New models sooner: a development cycle about 40% shorter means fresher technology in showrooms.
- EyeSight moves forward: the new ECU links driver assistance with all-wheel drive, the brand's signature strength.
- Today's EVs remain a great choice: the Uncharted, Solterra and E-Outback are already on sale in Romania. See Subaru's electric range with prices and bonus and the Subaru Uncharted versions, with up to 592 km of range. The new ECU is meant for future models, and Subaru has not announced OTA updates for the current ones.
