不要吓湖人家 MG7根本不是BMW5的底盘好伐.........
雅阁加BMW3

她们不是中国人 他们是德国人吧 哈哈

对了 还有啊 楼主
MG6=550 就是一样的车

rover被bmw收购的时候没有一款拿得出手的、不落伍的车型
于是上了rover75这个项目，拿当时那代宝马5系，也就是e39的底盘改的前驱
后来rover破产，上汽买到了图纸，南汽买到了生产线
南汽什么都没改，就把rover75换了个名字mg7开卖
上汽把这个底盘拉长了10公分，这就是750
然后上汽又觉得产品线里需要有部a级车，又把rover75挤短了5公分，这就是550
今年的mg6嘛，就是550换了个壳子……
这个系列虽然有点宝马的渊源，但是改了太多，年代也很久远，拿宝马做招牌有点无耻了

不要乱说 你看看清楚MG6的底盘 跟MG7的一样么

<br />
不一样么？挤短了5公分而已

扯蛋 哈哈  
MG7也不是宝马的底盘 82808280

准确的说，rover75是bmw工程师设计的前驱车，跟宝马底盘没什么关系。电子控制系统可能是差不多的通用件。因此，MG7可能跟宝马有点关系。其他的狗p关系没有。

有些对，但是有些是值得商榷的。
ROVER 75当初使用了宝马的2个主要技术，而不是单纯地把宝马底盘后驱改前驱，甚至这2个技术也不是宝马在其车型里普遍采用的，只是Z型后悬挂与旧款5系相同。当然主要的是有宝马的设计标准和调教（75是ROVER设计人员和宝马合作设计的），ROVER 75的底盘还是不错的。

Press speculation at the launch that the 75 was based on the BMW 5 Series thanks to its large size and especially the central tunnel in the chassis (normally only found on rear wheel drive cars) and the BMW Z-Link suspension from the rear wheel drive BMW 3-Series, was Misinformed. The central tunnel was built into the chassis to increase structural rigidity, using a BMW-developed floorpan concept that had explored front wheel drive but which had been rejected and remains unused by the BMW brand up to the present day. As the 75 took shape, this core engineering was passed over to Rover and evolved into the Rover 75 structure. The tunnel concept with a front wheel drive chassis & Z-axle was subsequently also used by BMW for its new Mini, and remains in production, due to its extreme stiffness and resultant excellent chassis control.

The E39 (BMW 5Series)employs similar design to the E38 7 Series for the rear suspension, regardless of the model specified. This "four-link integral rear suspension" or "Z-link" axle was first introduced on the BMW Z1. With this, Chapman struts are utilised. Through precise toe angle changes, stable yet responsive handling without unwanted toe change effects under load is achieved.
荣威750就是把75的轴距拉长，内饰更改，其他不变。MG7和75一样。
荣威550把750的底盘轴距缩短，后悬挂更改简化，底盘其他也不做完全的改动。所以，550的车重和750是相差不大的。
MG6和550底盘完全一样，不做任何改动，共线生产。
所以，说荣威750用宝马5系的底盘是不对的，但有宝马技术和设计以及调教。
550和MG6和宝马5系的关系又远了一层，纯宝马技术少了（如那个Z悬挂），但底盘还是保留了一些宝马的设计及调教。

是飞机的底盘
