那个320SI和量产版本的是两个概念,当时BMW出E90320i的时候特别推出个一个版本的320SI,和装备N46发动机的320i相比,这个车使用了N45的发动机,N46的320有150马力(后来升级到156匹),而320SI是170马力。注意320SI完全是拉高红线转速来的,和N46的320相比还没使用Valvetronic气门技术,实际上完全就是个拉高红线的跑街的车。
而WTCC上的320SI跟量产的只是有点渊源而已,WTCC上的320SI用的是基于N45的P45发动机,有275马力!!况且这车非常轻,加上驾驶员才有1100KG多点,变速箱还是直齿的序列式变速箱,传递效率那是相当的高,他比EVO快太正常了。
下面是从国外网站Copy来的WTCC 320SI资料。
