Key facts
- BYD plug-in hybrids exceeded declared fuel consumption in charge-sustaining mode.
- A Geely-affiliated electric sedan's wheelbase deviation exceeded the permitted 1% margin.
- MIIT identified documentation omissions and component discrepancies in commercial vehicles.
- Regulators ordered corrective measures and suspended certain model approvals for non-compliant vehicles.
- The action is part of Beijing's effort to address excessive competition and potential corner-cutting in the auto market.
China's Ministry of Industry and Information Technology (MIIT) has publicly identified BYD and a Geely affiliate for failing to meet production consistency standards, signaling an intensified regulatory focus amid a fierce price war in the domestic electric vehicle market. The MIIT's 2025 production consistency inspection found that BYD plug-in hybrids exceeded their declared fuel consumption in charge-sustaining mode, while a Geely-affiliated electric sedan exhibited wheelbase deviations beyond the permitted 1% margin of error.
In addition to these passenger vehicle issues, the MIIT also cited several commercial vehicle manufacturers for problems including missing user manuals, using unapproved component suppliers, and safety features failing to meet national standards. These findings expose vulnerabilities in fuel efficiency reporting, exterior dimension accuracy, and safety hardware compliance.
Regulators have ordered corrective measures for the identified violations and suspended certain model approvals. This action underscores Beijing's escalating efforts to curb excessive competition and prevent manufacturers from compromising quality and safety to reduce costs. The MIIT's move reinforces strict compliance standards and aims to ensure technical accuracy and supply chain quality control in the rapidly growing new energy vehicle sector.
