Washington's Bet on Secure Software-Defined Cars

Trade policy pushes automakers to build secure SDVs, opening the door to faster innovation and lasting consumer trust.

The US government has introduced new trade rules that set parameters for how software-defined vehicles will be developed and tested, aiming to secure supply chains while allowing room for innovation.

The Bureau of Industry and Security's Final Rule, which takes effect on March 17 2025, restricts vehicle technologies connected to countries such as China and Russia, though certain exemptions remain in place. For carmakers, the measures represent both compliance hurdles and an opportunity to strengthen consumer trust.

At the centre of the framework is General Authorization No. 1, issued on June 10 2025. It allows activities including public road testing in the US for up to 30 days a year and temporary imports for competitions or repairs. Automakers are required to keep detailed records for 10 years and demonstrate that their vehicles and software are free from links to restricted foreign entities.

The rules follow a phased schedule. Software restrictions will apply from the 2027 model year, while hardware requirements will begin with the 2030 model year. The timeline is designed to give manufacturers time to adjust supply chains, redesign key systems and invest in compliant technologies.

Analysts said companies that can show transparency in their processes are likely to gain advantages in regulatory clearance and consumer confidence. Supporters of the policy argue it embeds accountability at the heart of a sector increasingly defined by its convergence of mobility and computing.

Critics, however, warned of added complexity and cost. Yet many industry observers expect the regulations to reinforce existing trends, such as sourcing from domestic and allied partners, strengthening cybersecurity measures and integrating compliance into early design stages.

The policy underlines Washington's view that the shift to software-defined vehicles will require not only technological advances but also secure and verifiable practices. While the transition may prove demanding, it is expected to establish a foundation for cars that are both innovative and trusted.
