Summary of Key Points
At the launch of its new L8 model, Li Auto refuted the claim that "the end of range-extended vehicles (REVs) marks the beginning of pure electric vehicles (PEVs)," proposing instead that "the future of REVs lies in 5C-range extension" (which utilizes an 800V high-voltage platform to achieve a 10%-80% charge in just 10 minutes, providing a pure electric range of 430 kilometers). NIO, on the other hand, insists that "the end of REVs is PEVs," supporting this view with sales data showing an increase in PEV sales and a decline in REV sales. REVs were once very popular due to their ability to address consumers' concerns about battery range, but sales have started to slow down since the fourth quarter of 2025, driven by advancements in pure electric charging technology and changes in purchase tax policies for 2026. However, industry experts believe that new REV models with longer ranges and lower energy consumption could potentially revitalize the market.
I. The Confrontation Between Li Auto and NIO: The Debate Over the "Path Forward"
This is not the first time Li Auto and NIO have clashed, but this time the tension is particularly high:
- Li Auto's Perspective: REVs are not a transitional technology but have a future—“the end of REVs is 5C-range extension.” Their new L8 model uses an 800V high-voltage platform and 5C fast-charging batteries, offering a pure electric range of 430 kilometers and the ability to charge up to 80% in 10 minutes (similar to fast smartphone charging). This approach retains the backup option of using gasoline for power when the battery is low while addressing the issue of slow charging. CEO Li Xiang emphasized that PEVs and REVs serve different use cases and are not competitive; REVs are suitable for long-distance driving and outdoor activities, effectively eliminating range anxiety.
- NIO's Response: NIO's executives only responded with the word “thank you,” possibly implying they appreciate Li Auto helping to generate media attention. However, NIO has previously stated that the future of vehicles lies in PEVs, citing data from the China Association of Automobile Manufacturers (CAAM) showing that in May, 886,000 PEVs were sold (a year-on-year increase of 16.6%), compared to only 95,000 REVs (a year-on-year decrease of 24.9%). This data supports their belief that PEVs represent the trend.
In short, Li Auto believes REVs can evolve, while NIO thinks they will eventually be replaced by PEVs.
II. The Rise and Fall of REVs in the Market
REVs became popular because they addressed a common issue for consumers:
- Li Auto's Lead: The Li ONE was the first model to successfully market REVs, enabling new entrants in the automotive industry to achieve profitability on a large scale. The concept behind REVs is simple: use electricity for normal driving (quiet and cost-effective) and switch to a gasoline generator for long distances or when the battery runs out (no need to find charging stations, similar to fuel vehicles), effectively combining the advantages of both electric and fuel vehicles.
- Followers from Other Companies: Brands like Xpeng, Leapmotor, and Deep Blue have also launched REV models, especially mid-to-large SUVs, which often have heavy weights and limited pure electric ranges. These models have performed well in sales.
In summary, REVs appealed to consumers who wanted the convenience of an electric vehicle without the range limitations of traditional fuel vehicles.
III. The Current Decline in REV Sales
Sales of REVs have been declining since the fourth quarter of 2025 due to two main factors:
- Advances in Pure Electric Charging Technology: The widespread adoption of 800V high-voltage platforms and ultra-fast charging technologies (such as those in the Xpeng G6 and BYD Sea豹 07) has significantly improved charging speeds. With more charging stations available, especially on highways, consumers' range concerns have been alleviated, reducing the need for REVs.
- Policy Changes: Starting in 2026, REV models must meet specific requirements to qualify for purchase tax incentives: a pure electric range of at least 100 kilometers and a lower fuel consumption compared to similar fuel vehicles. Many older REV models (with small batteries and high fuel consumption) no longer meet these criteria, resulting in the loss of their price advantages.
These factors have weakened the appeal of REVs compared to pure electric vehicles.
IV. Is There a Future for REVs?
Despite the decline in sales, industry experts believe that REVs are not doomed:
- Evolution of New Models: The number of new REV models on the CAAM catalog is increasing, with growing ranges (140 kilometers in 2024, 174 kilometers in 2025, and 215 kilometers as of June 2026). Longer ranges mean more scenarios where electric driving is feasible, reducing the need for fuel consumption.
- Targeted Solutions: Models like Li Auto's 5C-range extension models balance long-distance capabilities with fast charging, appealing to users who frequently drive long distances and value convenient charging. If REV models can achieve longer pure electric ranges, faster charging, and lower fuel consumption, they may still attract a specific market segment.
In conclusion, REVs will not disappear, but they need to evolve to remain competitive. This will require advancements in technologies such as 5C fast charging and longer ranges to adapt to changing market demands.
Final Summary
The competition between REVs and PEVs is not about one being completely superior to the other; rather, they serve different user needs. PEVs are suitable for urban commuting with easy access to charging facilities, while REVs are better for long-distance driving where charging may be inconvenient. The winner will be the technology that best meets consumers' real needs.
