Li Auto Earns World-first SGS Premium Performance Mark for Automotive Cellular Communication

BAAR, Switzerland - July 14, 2026 - PRLog -- SGS, the world's leading testing, inspection and certification company, is delighted to announce the first award of the SGS Premium Performance Mark for an automotive cellular communication product.

Li Auto's L9 Livis 5G high-performance intelligent cockpit platform was evaluated using SGS's proprietary testing protocol for automotive 5G cockpit communication (PT-26-000-105640). The assessment evaluates product performance across multiple technical dimensions using a structured and rigorous methodology. The SGS Premium Performance Mark focuses on real-world connectivity performance rather than isolated technical parameters, reflecting a more comprehensive approach to evaluating in-vehicle communication capabilities.

Connectivity was translated into performance using measurable indicators, providing a structured and consistent approach to assessing real-world user experience, and SGS's independent and rigorous testing demonstrated that the platform exceeded standard thresholds across all four dimensions:
- Connection stability
- Bandwidth capacity
- Weak-signal recovery capability
- Performance under network congestion for key services

Stable connections, efficient data transmission and a responsive user experience distinguished Li Auto's platform, credibly demonstrating validated high performance under real-world conditions.
