数据好看啊

好贴，有意思

自从国庆开着老婆的118i回老家接人，畅快的跑了300公里盘山路，现在又看了您的技术贴，我有点想把自己的325换掉的冲动，人比人 气死人，车比车 得换啊

楼主你好，帖子分析的头头是道，我外行都懂了。那请问e90的320能抄底吗？需要注意哪些问题入手

钱够直接M3呢，钱够也就不纠结这个问题了。另外325AT 是7秒1不是8秒5 宝马澳大利亚当年的手册上写的，N52B25发动机。

宝马在美国也推出过325i,早期的排量是2494ML, 国内的325是2497ML, 但是美国也有2497ML的，叫323i。*****
可见这个发动机并非专供中国。
在德国网站也能查到，曾在欧洲市场销售过325i,2.5升的

至于说325MT 6.9秒破百 我相信的，因为我看过视频。既然加速这么快说明发动机很好，AT加速慢无非就是百公里已经换了3档，而且6AT换挡也不是很快，拖了后腿。而MT 是2档就可以破百。那说明发动机没什么问题，油耗比330高是说的通的，举个极端的例子，小马拉大车 比大马拉小车那费劲多了。一个理。

吵来吵去的没意思，首先，325并不是楼主说的到中国后的阉割版。如果你翻墙，去google一下，看看真实的B52B25，共三种版本，130KW,150KW以及160kw，针对不同市场进行不同调校。 国内上市的是160KW (218HP)版本，网上很明确，这一款是针对除了北美市场之外的所有其他市场。并不是中国独有。

我试过325并且刷过ecu的。感觉确实要比我的原装325油门响应快 并且动力猛一点。
