Google Cloud and Valtech have released the open-source core of Nexus SDV, a software-defined vehicle platform designed to support connected car systems at scale.
Nexus SDV is a modular platform for managing connected vehicles, processing telemetry and linking cloud services with software running in the car. It is designed to support as many as 100 million devices and uses Arm-based compute and Bigtable for data processing and storage.
At the centre of the platform is Nexus AI, which uses Gemini models and the Gemini Enterprise Agent Platform to analyse vehicle telemetry in real time. Security features include mTLS-backed communication, Keycloak identity management, and gated Bigtable data APIs.
The open-source repository is available at https://github.com/GoogleCloudPlatform/nexus-sdv under version 1.1.0 (March 2026).
