Distinguished leaders, guests, good afternoon!

Next, I will report to you on our research findings regarding the "Top 10 Automotive Technology Trends in China for 2026."

The technology trend research system conducted by the Society focuses on two major aspects: first, linear technological innovation following current technological directions, and second, non-linear technological innovation driven by disruptive technologies. Centered around these two innovation directions, we have established an automotive technology foresight research system.

We initiated annual technology trend research in 2021 and released frontier technology trends in 2022. In 2024, we released the "Top 10 Technology Trends for Global Intelligent Connected Vehicles." This year, we have also conducted focused technology trend research in key areas, including intelligent cockpits, AI+Automotive, flying cars, and energy efficiency of new energy vehicles, among others. Today, I will primarily share with you the "Top 10 Automotive Technology Trends in China for 2026" from our research.

Our focus areas are based on the "Technology Roadmap for Energy-Saving and New Energy Vehicles," involving 5 major technology clusters and 26 key topics. The key technology types we focus on include three aspects: first, technologies achieving major breakthroughs; second, technologies achieving new mass production in 2026; and third, technologies experiencing significantly expanded application scale.

Regarding these key areas and three technology types, we conducted four rounds of Delphi surveys. Nearly 400 experts from 120 organizations participated in the research, including over 60 senior experts.

​​Trend 1: Convergence of L3 Conditional Autonomous Driving Solutions​​

L3 is the critical watershed from assisted driving to autonomous driving. Promoting industry consensus on L3 solutions—including hardware configuration, algorithms, and computing power—is an important basis for formulating relevant standards and the fundamental prerequisite for achieving scaled product deployment and commercialization. We anticipate that in 2026, L3 conditional autonomous driving will evolve from the current exploration relying on feature stacking and configuration redundancy towards a new stage characterized by unified technical solutions and optimized system efficiency.

​​Trend 2: New Mass Production Phase for End-to-End AI Agent Intelligent Cockpits​​

End-to-end AI Agents for intelligent cockpits will possess multi-modal fusion perception and contextual reasoning capabilities, promoting the paradigm shift from humans adapting to vehicles to vehicles adapting to humans. In 2026, end-to-end AI Agents for intelligent cockpits will usher in their first year of mass production, evolving towards multi-modal collaboration, long-term memory, and multi-scenario services.

​​Trend 3: Large-Scale Adoption of HBM Chips in High-End Models​​

HBM chips offer advantages such as ultra-high bandwidth, low latency, low power consumption, and high integration. They provide critical support for real-time processing of complex algorithms and massive data, and are the preferred hardware for the next step in high-level autonomous driving and high-end intelligent cockpit deployment at the edge. We forecast that HBM solutions will achieve mass production installation in high-end models first in 2026, with a penetration rate exceeding 30%. Widespread application is expected within the next 3-5 years.

​​Trend 4: Over 100 Models of Electric Heavy-Duty Trucks Supporting Megawatt Ultra-Fast Charging​​

Steady-state megawatt-level DC fast charging technology offers advantages like high compatibility, low cost, and minimal maintenance. It is an important means to solve the energy replenishment efficiency bottleneck for commercial vehicles and promote large-scale commercialization. We estimate that by 2026, newly launched commercial vehicles supporting megawatt ultra-fast charging could number over one hundred models, promoting the current application of electric heavy-duty trucks from urban short-haul further into medium- and long-haul, open scenarios.

​​Trend 5: Mass Production of High-Battery-Capacity HEVs in the Global Market​​

High-battery-capacity HEVs refer to those equipped with batteries around 5 kWh. These larger batteries combine high power and high energy storage capabilities, serving as a key cornerstone for systematically improving the smoothness and energy efficiency of HEV vehicles while expanding intelligent functionality. In 2026, HEVs equipped with around 5 kWh batteries are expected to be promoted and applied both domestically and internationally.
