2026 年 3 月 31 日，標誌著香港汽車稅制的一個重要轉折點——實施近八年的「一換一」(One-for-One) 私家車稅務寬減計劃正式結束。根據 REV Channel 的分析，這項政策自 2018 年推出以來，讓香港電動車數量從數千輛迅速增長到超過 14 萬輛，推動了香港電動化進程。但隨著政府邁向「用者自付」(user pays) 原則，免稅的黃金時代正式落幕。 一部車貴了 17 萬：電動車稅制回歸現實 REV Channel 提到過去一部約港幣 29 萬元的熱門電動車，在「一換一」政策下能享受高額稅務寬減；但新制上路後，同款車可能要付出超過 46 萬元。從 2026 年 4 月起，電動、混能與汽油車的首次登記稅（FRT）將趨於一致，結束了電動車長期以來的稅制優勢。對消費者而言，這意味著「你的下一部新車」可能立刻變得貴上十幾萬。 「報廢名額」狂潮與最後的搶購潮 政策截止前夕，「報廢換車名額」（CLA）市場熱到不行。據 REV Channel 報導，名額交易價格一度飆至港幣 4 萬至 7 萬元，引發車主爭相在 2 月 25 日前完成
