为什么X5 35d用的只是6-speed transmission？其他gas的版本都是8-speed。
但是Touareg，Q7和Cayenne TDI都是8-speed。
资深TX们，有没有知道为什么啊？有什么历史原因吗？
8-speed的工艺似乎比6-speed难很多吧，成本有没有差一大截吧？

The BMW X5 35d has a six-speed automatic transmission where eight-speed has
become the standard. Throttle tip in is well matched and one doesn’t sense
turbo lag. BMW’s motor has two different size turbos that kick in at
different phases of the rev range. What it means to the driver is nearly non
-existent turbo lag. Step on the throttle on the highway and the torque
curve always seems to be in the right spot and you get a nice shove in the
back. In 2011, BMW had its mid-cycle refresh for the BMW X5 and updated many
things in the X5 models, however, the diesel X5 35d’s engine and
transmission remained unchanged.
Porsche’s diesel motor thrust is transmitted to the wheels through an 8-
speed automatic “Tiptronic S” transmission. The Porsche is saddled with
their ass backwards thumb shifters on the steering wheel. Fortunately the
gear leaver in the center console is intuitive. I love Porsche paddle
shifters, just not these ’80s style block – thumb shifters, but I confess
that this is subjective and that others may not loathe them like I do. This
8-speed transmission routes power to a permanent all-wheel drive. All this
is good for 0-60 in 7.2 sec. Highway mileage is an astounding 29 mpg,
combined with its fuel tank of 26.4 gallons, the Porsche has a mind blowing
range of 765 miles! City MPG is also rated at 19 mpg. | t**********3

看图说话的话，X5 35d是直六 diesel不是V6啊？
【在 t**********3 的大作中提到】
: X5跟Cayanne一比似乎很屌丝啊

没有lag如果贡献来自两个turbo有道理。
但是是否6-speed 齿轮比也有关系。如果换成8-speed就会有lag？

发帖数: 12623 | 6 不好说，可能X5平台老了，宝马就不折腾在柴油车上8AT了，但是新款的35d应该是8AT
了，否则没天理了。
卡宴那个V6柴油其实是大众的发动机，我之前在版上发过揭了塑料cover里面的VW标志
，不过这款V6 TDI机真是好，噪音和振动都比宝马和奔驰的6缸涡轮柴油机小不少，开
起来也smooth许多。
