At the 2026 World Intelligent Connected Vehicles Conference, BYD Senior Vice President Yang Dongsheng stated that "there is hope" for restricted-scenario L3 in 2028. XPeng Chairman He Xiaopeng predicted that L4 technology would be implemented in the second half of 2028 and advocated for skipping L3. Momenta founder Cao Xudong, meanwhile, judged that 2028 could become a significant turning point for increased L3 and L4 penetration, and revealed that some clients have already designed L3 systems based on L4 architecture to reduce redundant investment.
