考慮購置 5系列5門掀背車款 (Touring)
考量油耗成本, 計畫購買柴油引擎車款. 目前有兩款選擇 520D & 525D.
不知有沒有車友可給點有關 525D車款的訊息？
Google 了一下, 525D Touring 車款國內的資訊並不多.
而且25D 這個編號也是很獨特的編號, 其他車種目前並沒有這一編號的車型.
是否是較舊的引擎設計？

確實，F11原本是沒有525d touring的
但小改款之後，525d touring成為F11最頂級的車型，記得牌價是302~
這款是最新的哦~~小改款了嘛~
14年式要加尿素~
彰化昌一原本有一台現車~
12月底車友差一點就買了，無奈價格談不攏~差了3萬元~

小弟對柴油引擎其實不熟,
只是因為對 Touring 的喜愛而注意到 25d 這顆引擎.
以下若有謬誤還請指正.
從有限的資料看起來, 這是一顆很新的引擎版本,
從排氣量, 缸徑, 衝程等數據來看,
應該和520d的 N47 引擎系出同門.
但又是一顆具有兩顆渦輪(Twin Turbo)的引擎,
而非只是 TwinPower 的"雙渦流",
也許可以看成是把雙渦輪技術下放到四缸的N47進化版吧.

The BMW 525d will get a new four-cylinder diesel engine with BMW TwinPower Turbo technology. This 2.0-litre all-aluminium unit features Variable Twin Turbo two-stage turbocharging and common-rail diesel injection with piezoelectric injectors. The new BMW 525d offers a 10 kW power increase over the previous model, developing 160 kW/218 hp at 4 ,400 rpm. The small turbocharger comes on stream at low engine speeds, while the contribution from the larger turbocharger varies in precise response to throttle requirements. 0-100 km/h (62 mph) acceleration times, which now stand at 7.0 seconds for the Sedan. Average fuel consumption is 5.0 ? 5.3 l/100 km (automatic: 4.8 ? 5.0 litres).

這顆引擎是用來取代之前直六引擎的 525d(2,993cc, 204ps, 台灣好像沒進過),
有點像是四缸turbo 528i 取代以往直六3000cc 528i 的模式:
BMW has held onto their straight 6 for the new F10/F11 525d, in the first phase of production of the car. Then in the 2nd part of 2011 the straight six was substituted by a diesel twin-turbo 2 litre developing 218 bhp and 450 Nm of torque, the same figure of the old straight six. The badge on the rear of the car says still 525d. Please note that this new 2.0 diesel twin.turbo develops 50 Nm and 14 bhp more than the old 123d engine (with 400Nm and 204 bhp,[4] ).
也可以把這顆25d引擎看做是123d上那顆23d引擎的加強調校版.
23d這顆引擎得過 International Engine of the Year 大獎.
Twin turbo version[edit]
In October 2007, BMW introduced a twin sequential turbo model. With 204 bhp, it is the first production diesel on sale to achieve a specific output of over 100 bhp per liter. It uses the same turbo technology first shown in the E60 535d.
This engine is on sale in the E81/E82/E87/E88 123d and the E84 X1 xDrive 23d. This is the engine, which won the International Engine of the Year Award 2010.
Wiki: BMW N47
International Engine of the Year
也許因為這顆引擎太新, 所以國內資訊還很少.
但新的X5 25d 應該也是這顆引擎.
另外, 搜尋123d應該也可以找到更多相關的評論.
