2025 SDV Survey: Automotive Industry Is Betting on AI, OTA Updates and Advanced Software, Though Obstacles Remain

Annual survey carried out by Wards Intelligence, now part of Omdia, and sponsored by Sonatus highlights major progress in shift to software-defined vehicles

Sonatus, a leading automotive software company accelerating the shift to software-defined vehicles (SDVs) through artificial intelligence, has sponsored the 2025 edition of the Software-Defined Vehicle Survey, an annual global survey conducted by Wards Intelligence, now part of Omdia. Sonatus today revealed some key findings from that survey in the form of an eBook. Carried out in March 2025, the survey gathered insights from more than 500 automotive professionals spanning Asia, Europe and North America. The study explores the industry's evolving technology priorities, reflecting a decisive shift toward AI, embedded software, and its future potential.

The industry is shifting gears to software

The study reveals a significant shift in perspective: while data management and systems integration dominated last year, AI and software-related capabilities are now at the top of the priority list. Across all regions, respondents cite AI-based automotive functions, OTA updates, continuous software deployment (CI/CD) and automated software recertification as key elements of future mobility.

Another notable finding is the increasing viability of open-source solutions in safety-critical applications. Where proprietary systems previously dominated, Linux-based platforms are now gaining confidence, a shift that reflects a growing need for flexibility and scalability. 83% of respondents are considering Android and Linux in safety systems, compared to 2024, when only 12% considered Linux viable.

AI as a driver of new capabilities

AI is generating a lot of excitement globally, but not only in areas such as advanced driver assistance systems (ADAS) and automated driving. Notably, four of the five most promising AI use cases — smart diagnostics, dynamic performance calibration, personalized driving comfort optimization, and predictive maintenance — are not yet widely deployed. Routing and navigation, which is increasingly deployed in IVI systems today, was #4 on the list. This suggests a significant untapped opportunity in foundational vehicle functions, not just infotainment or voice interfaces.

OTA Updates are becoming more pervasive

67% of respondents said over-the-air (OTA) updates were already deployed in their vehicles, an acceleration of this shift compared to last year. However, OTA updates are not yet pervasive across all vehicle systems. Only 23% of respondents say OTA are used today for upgrades to vehicle capabilities, though an additional 55% (or 78% cumulative) expect broader deployment by 2026-2027.

A modular and progressive approach to software architecture

Vehicle architectures are evolving to support scalable, software-centric platforms. Overall adoption of hardware and networking technologies will begin with high-speed in-vehicle network backbones with higher prevalence in 2027, followed by consolidated hardware running multiple workloads with abstraction around 2028. Vehicle platform standardization is expected to occur around 2029, with the transition to zonal architecture beginning from 2030 onwards. Variants of zonal architectures are expected to be the majority during that period.

Structural challenges to overcome for a successful transition

Despite a clear momentum towards software-defined vehicles, survey replies identified several obstacles to large-scale adoption. Cost optimization and ensuring ROI topped the list (29%), along with data management and privacy (27%), and legacy systems, operations and mindset (26%). Fortunately the journey is seen as worth the effort, as 82% of respondents believe SDVs will be either very successful or somewhat successful in achieving key industry goals like enhanced in-car experience, increased quality, new revenue streams, and faster product development and innovation.

Sonatus: Accelerating the shift to SDV

To help accelerate the shift to software-defined vehicles with artificial intelligence, Sonatus offers a modular platform of crucial software infrastructure, which is in mass-production in millions of vehicles. For example, Sonatus Collector offers highly configurable dynamic data collection, and Sonatus Updater provides a modern powerful solution for the increasingly complex OTA update requirements of SDVs.
