樓上那位太帥了~ 再補充一個網頁 http://prius.ecrostech.com/original/Understanding/ContinuouslyVariableTransmission.htm "Toyota calls the Prius transmission "ECVT" which is either "Electrically Controlled Variable Transmission" or "Electrically Controlled Continuously Variable Transmission", depending on where you read it. So is it "Continuously Variable" or not? We shall see that the answer is both yes and no."
不管哪一種形式只要是無級變速都叫 CVT ,早期 CVT 前面加個 E 是代表為可程式控制傳動比,比如像PUNTO MK2 的排檔座上有一個 E 符號經濟模式的開關( 剛好也是 E ),開啟的時候在時速100的速度下巡航的時候,引擎轉速可以降低到約2100轉,而例如像 MARCH 的 NCVT 就是無法用電腦控制傳動比的。
