在新能源汽車的賽道上，插電式混合動力（PHEV）與增程式技術路線的爭議不斷，而在3月底的中國電動汽車百人會上，關於“增程式技術更具優勢”的言論，更是引發行業對兩種技術路線的深度探討。從實際而言，從技術、市場、政策等多維度審視，插混技術展現出獨特魅力與廣闊前景。

技術層面，插混融合純電驅動、發動機直驅、串聯與並聯四種模式，技術複雜度遠超增程式。它涉及發動機研發、多檔DHT變速箱調校以及動力系統協同控制等高難度技術，研發門檻極高。插混模式可靈活切換，低速用電經濟高效，高速直驅減少能量損耗，急加速時並聯提供強勁動力，全場景綜合效率更高。比亞迪秦PLUS DM-i在高速直驅模式下，油耗低至4L/100km ，比增程式車型節油15%-20%。同時，在相同硬體配置下，插混車型並聯模式能實現發動機與電機雙動力疊加，零百加速比增程式快30%，虧電狀態動力衰減小，安全性更高。而且，插混雙動力源設計在安全上更具冗餘，即便一系統故障，車輛仍能行駛。

成本與規模化方面，插混雖前期需投入高額研發攻克多檔DHT技術，但電池容量較小（15-20kWh）。隨著規模化生產，邊際成本下降空間大。比亞迪通過垂直整合供應鏈，已將插混車型價格下探至10萬元區間，以高性價比吸引大量家庭使用者。2023年，比亞迪插混車型銷量突破百萬輛，彰顯其市場競爭力。

In terms of policy, China's new energy subsidy policy is tilted towards plug-in hybrids, and Europe has also forced car companies to choose plug-in hybrid routes through strict carbon emission regulations, because plug-in hybrids can achieve lower fuel consumption and carbon emissions by optimizing power distribution, which is more in line with environmental protection trends.

從市場定位看，插混憑藉“性價比+全場景適用性”，以10-20萬元價格帶覆蓋家庭使用者，滿足城市通勤與長途出遊雙重需求，完美契合大眾市場。而增程式主打高端市場，依賴大容量電池，受原材料波動影響大，且高速能耗高、動力和安全性能存在短板。

Of course, plug-in hybrid technology also faces challenges, such as high R&D costs and technical difficulties. However, in the long run, plug-in hybrid technology will continue to expand its technical advantages by popularizing multi-speed DHT to improve high-speed direct drive efficiency, and deeply integrating intelligent energy management systems to achieve "scene adaptive" power distribution, and the comprehensive advantages of plug-in hybrid technology will play a more important role in the process of new energy transformation.
