The Great SDV Decoupling:
How US and European Policies Are Reshaping Chinese Technology in the Automotive Landscape
SDV Insights | viable.works Technology Consulting • May 2026
The automotive industry is entering a new phase of structural geopolitical fragmentation. A pivotal development is the US Connected Vehicle Security Act of 2026, a bipartisan bill introduced in late April 2026 by Senators Bernie Moreno (R-OH) and Elissa Slotkin (D-MI).
The legislation aims to prohibit the importation, manufacture, sale, and operation of connected vehicles and their related software and hardware that are linked to China or other foreign adversaries (including Russia, Iran, and North Korea). It targets not only complete vehicles but also critical components, data systems, and any entities with significant Chinese ownership or control.

For Chinese technology providers and OEMs dependent on them, the consequences for Software-Defined Vehicles (SDV), ADAS, powertrain electronics, and high-performance computing (HPC) architectures are significant and long-term.
At viable.works we monitor these developments closely through our platform comparisons, including our Automotive HPC / SoC Comparison. The trajectory is clear: US and Chinese vehicle technology stacks are diverging rapidly, while Europe remains a contested middle ground under sustained regulatory attention.
1. US and Chinese markets are heading toward completely disjoint technology stacks
The Act effectively creates a structural barrier for Chinese-origin ADAS, SDV platforms, powertrain controllers, and supporting HPC solutions in the US market. Because virtually all modern vehicles are connected (via OTA updates, telemetry, infotainment, etc.), the scope is extremely broad.
Key Implications:
- US-market vehicles will rely almost exclusively on Western technology stacks (NVIDIA, Qualcomm, Mobileye, and others).
- Chinese OEMs and their suppliers will continue to optimize for domestic and Global South architectures.
- Intercontinental OEMs will need to maintain parallel or highly modular technology stacks to serve both markets.
2. Europe remains accessible — but under permanent regulatory scrutiny
Europe has not introduced an outright ban. However, the regulatory environment is tightening through:
- Anti-subsidy tariffs on Chinese EVs
- Enhanced Foreign Direct Investment (FDI) screening
- Ongoing cybersecurity risk assessments (NIS2 and Cybersecurity Act)
- National-level restrictions in sensitive applications
European OEMs with notable Chinese ownership or joint ventures face continuous compliance exposure. Europe functions as a strategically important yet politically contested market.
3. Global OEMs must prioritize supply-chain resilience and architectural agility
OEMs and Tier-1 suppliers aiming for presence across the US, Europe, China, and emerging markets face a strategic imperative: develop architectures that can adapt quickly to regulatory change. Success will depend on control over E/E architecture, zonal controllers, HPC selection, operating systems, and communication protocols.
4. A significant opportunity for independent technology partners
This fragmentation increases demand for neutral, geopolitically resilient technology solutions and advisory services that help OEMs manage complexity across multiple regulatory regimes.
Strategic Outlook
Geopolitics has become a core design parameter in SDV development. Organizations that treat the US–China decoupling as a planning input today will hold a decisive advantage tomorrow.
