標題: 拉低成本 瑞麒M1 1.0L將更換發動機 [打印本頁]

作者: mattiefred0603    時間: 2011-2-14 01:19     標題: 拉低成本 瑞麒M1 1.0L將更換發動機

做為奇瑞今年戰略重組的重要環節,瑞麒中高端車型正式上市,第一款車型正是北京車展上暴光的是五娃車之一的NN,當然上市後的定名是瑞麒M1,但從上市以後的表現看,反響平平,這可能與其過高的定位有莫大的關聯。


中高端車系是否就限制住了M1的定價?這種連動關係還是客觀存在的,畢竟奇瑞旗下還擁有更為出名的QQ系列,相近的空間利用率,卻有著更為低廉的售價,上市之初為拔高形象而上市的1.3L並未相應的提升奇瑞在中端微車領域的聲望,以至其1.0L與AMT自動檔型號都未能扭轉局面,降價?如何操作成了關鍵,本期目錄中的M1 1.0L到是提供了一個可行方案。

非常湊巧,奇瑞在1.0L及以下發動機本期全部湊齊,SQR7080S117、SQR7101S187、SQR7101S217分別是搭配0.8L的QQ3、搭載1.0L發動機的M1與搭載1.0L發動機的旗雲1,而位於表格中間的車型裡的動力型號卻是首度出現——SQR371F型發動機,第一格中的則是0.8L 372型發動機,3代表三缸發動機,72則代表發動機缸徑為72mm,相應的,最後一格中的SQR472FB發動機就代表四缸,72mm缸徑,這樣一來,也就完全解釋了SQR371的含義,三缸發動機,71mm缸徑,做為一款1.0L發動機,缸徑還小於0.8L型,很明顯其缸內行程大於0.8L。


目前在銷的M1 1.0L車型搭配的動力型號是SQR472FB型,也就是本期目錄表格中旗雲1搭載的動力型號,參數為最大功率50Kw/6000rpm,最大扭矩93Nm/3500~4000rpm,與之對應的SQR371F型將會是怎樣的動力參數值呢?目前還沒有更進一步的信息可供參考,除了幾張圖片外,只知道此機第一次點火成功是在2007年五月(第一台樣機),而動力數值應該與目前採用的SQR472FB型相接近,否則以M1的990公斤重量看,推動起來會非常吃力,另一個顯著的改善就是三缸機相比四缸機能有效的降低整備質量,同時降低生產成本,當然缺點也不能忽視,就是三缸機相比四缸機,在運行的穩定性上(三缸機的抖動)可能會有不同程度的降低,當然發動機本身如果在懸置點的設計上達到優化的話,起碼會比現在在銷車型能有更好的運行穩定性。


由上面暴光的SQR371整機圖看,與目前QQ3上搭配的SQR372性發動機在外特性上(外觀造型)區別較大,甚至與四缸的472型區別也不小,應該是一款全新開發的二代機型,另外此機同時開始測試的還有VVT款機型,當然本次出現的SQR371F裡最後的英文大寫字母F表明這是一款自然吸氣型,並不會匹配VVT技術,這與降低成本也有著莫大的關聯。

雖然最先搭載於M1,但其技術指標以及穩定性一但達標,大規模鋪裝旗下所有微車的可能性會很高,畢竟微車更為注重的還是成本與利潤的均衡,目前唯一剩下的懸念就是其動力參數值。
