A BYD electric SUV with a 130.15-kWh battery pack and a claimed range of 950 kilometers (about 590 miles) has cleared China’s official vehicle approval process, according to filings published by the Ministry of Industry and Information Technology in spring 2025. Chinese automotive outlet Autohome and other domestic media have identified the vehicle as part of BYD’s Fangchengbao sub-brand, though BYD itself has not issued a press release confirming the model designation. If the figure holds anywhere close to real-world conditions, the SUV would rank among the longest-range battery-electric vehicles to reach production status anywhere in the world.
The range is measured under China’s CLTC testing standard, which is more forgiving than the U.S. EPA cycle. That distinction matters: a 950-km CLTC rating would likely translate to a lower EPA-equivalent figure, though no official EPA conversion exists for this specific model and no single published study provides a universal CLTC-to-EPA discount factor. Comparisons across vehicles that have been certified under both protocols suggest the gap can range from roughly 20 to 30 percent, which would put an EPA-style estimate somewhere around 400 to 480 miles. Even at the lower end of that rough estimate, the SUV would still outrange every electric SUV currently on sale in the United States.
What the regulatory filing reveals
The specifications surfaced in a batch of China’s New Energy Vehicle purchase-tax exemption directory, a government-managed catalog that automakers must enter before their models qualify for tax incentives. The directory is jointly administered by MIIT, the Ministry of Finance, and the State Taxation Administration. Automakers submit detailed technical data, including battery capacity, energy consumption per 100 km, and CLTC range, as part of a structured compliance process. Once approved, the figures become part of a publicly accessible catalog that Chinese media and industry analysts treat as authoritative.
Because the directory is the gateway to significant consumer savings on purchase tax, automakers have a strong incentive to file accurate data. Overstating range or battery capacity risks rejection or later removal from the catalog, which would strip the model of its tax advantage and damage buyer confidence. This built-in accountability is why Chinese automotive outlets routinely cite directory filings as reliable spec disclosures rather than unverified marketing claims.
The policy framework governing the catalog for the current incentive period is laid out in a joint ministerial announcement covering 2026 and 2027 technical requirements. That document sets minimum thresholds for battery efficiency, energy density, and other performance metrics. BYD’s filing, by clearing those thresholds, confirms the 130.15-kWh pack meets the government’s baseline standards.
A massive battery pack in context
At 130.15 kWh, this is one of the largest battery packs ever fitted to a production passenger vehicle. For comparison, the Tesla Model X Long Range carries roughly 100 kWh, the BMW iX xDrive50 tops out at about 105.7 kWh, and the NIO ES8 with its largest swappable pack reaches 100 kWh. Only a handful of electric trucks and ultra-premium sedans have crossed the 120-kWh threshold.
BYD manufactures its own battery cells through its FinDreams subsidiary, which produces the company’s well-known Blade Battery using lithium iron phosphate (LFP) chemistry. The regulatory filing does not specify whether this particular pack uses LFP, a ternary nickel-manganese-cobalt formulation, or a newer chemistry. That detail will matter for weight, charging speed, and cost. LFP packs are heavier per kilowatt-hour but cheaper and more thermally stable, while ternary cells offer higher energy density at greater expense. BYD has used both chemistries across its lineup, and the company has been investing in next-generation cell designs that aim to narrow the density gap.
Scaling production of a pack this size also raises supply chain questions. Sourcing enough cathode and anode material for 130-plus-kWh packs at volume is a different challenge than building the 60- to 80-kWh packs that dominate the mass market. None of the primary regulatory documents address production timelines, volume targets, or material sourcing plans.
What the filing does not tell us
Several important details remain absent from the directory documents. No direct BYD press release or executive statement has confirmed pricing, a specific launch date, or which markets the SUV will target beyond China. The filing does not disclose charging speed, curb weight, or how the SUV fits within BYD’s expanding brand portfolio, which now spans the budget-oriented BYD brand, the mid-premium Denza line, and the luxury Yangwang and Fangchengbao sub-brands.
“We have not seen any on-the-record comment from BYD about this vehicle’s timeline or target price,” noted one Shanghai-based automotive analyst who tracks Chinese regulatory filings but asked not to be named because they were not authorized to speak publicly. “The filing tells you the pack exists and meets the government’s bar. Everything else is inference.”
No third-party road test or independent dynamometer result has been published for this variant as of May 2026. The 950-km figure is a certified lab result produced under controlled conditions: moderate ambient temperature, limited climate-control use, and gentle driving speeds. Every major EV on the market shows a gap between its official rating and what owners experience across varied terrain, temperatures, and highway speeds. That gap is simply larger when the starting number comes from CLTC rather than EPA or WLTP testing.
What a 130-kWh SUV signals for the global EV market
Range anxiety remains one of the top reasons consumers hesitate to switch from gasoline vehicles. A production SUV that can credibly promise 400-plus miles of real-world range, even after accounting for the CLTC testing discount, would remove that objection for most drivers. It would also put pressure on established automakers who have struggled to push past the 350-mile mark in their electric SUV lineups.
BYD is already the world’s largest seller of new energy vehicles by unit volume, and the company has been expanding aggressively into Europe, Southeast Asia, and Latin America. Whether this particular SUV reaches markets outside China will depend on pricing, local certification, and the ongoing trade tensions that have led to tariff increases on Chinese-made EVs in both the European Union and the United States. But even as a China-only offering, a 130-kWh SUV with a 950-km rated range resets expectations for what battery-electric vehicles can deliver in 2026.
For now, the filing stands as the strongest available evidence: a government-approved specification, submitted under a compliance framework with real financial consequences for inaccuracy. The next milestones to watch are an official BYD product announcement, independent range testing, and any indication of export plans.
