以前大眾的車是跟Aisin拿6速自排,Aisin是豐田的子公司,所以命門不該掌握在敵人手裡這點大眾可是很清楚的,所以毅然決定更換變速箱。

DSG一般產商宣傳的優點是有手排的力卻又比自排省油(對比手,自排與CVT),但前提是DSG一直順順開這句話才能成立,DSG可以想像成是兩具手排串連在一起,車在1檔,2檔卡在那邊預備切換,換了2檔,3檔則卡在那準備做升檔動作。

但問題就在這裡,電腦並不能預知路況:
例如正在用3檔行走(4檔卡著預備中),突然要超車,大腳油門下去,電腦則判斷必須降檔,那自然必須把4檔拔掉再切回2檔,這過程會造成多餘的零件損傷,而且還會帶來頓挫感,讓駕駛員與乘客不舒服,造成整體乘車品質下降,就好像一個新手司機開手牙不知道該進檔還是推擋。。。那可是相當很可怕的。

現在傳統自排在平順度,油耗都跟手排不相上下,可能還更好。
未來給我選的話,除了電動車,我更願意要AT。
