(1)柴油的品質較講究，且要使用超級柴油，所需柴油的金錢消耗較傳統柴油引擎多。
(2)柴油的清潔度要更高，故要更重視燃料系統的保養與定期更換柴油濾芯子，避免有關零件磨損與阻塞。
(3)增添許多電腦控制零件與複雜的電腦控制線路，使維修更為困難與更需要專業性。
(4)燃料系統的零件正常使用後損壞，一般的汽車修理工廠根本無法分解、修理與調整，大多要直接更換零件總成，比如噴油器、油軌總成、電動柴油泵浦等。且更換零件所需金錢費用亦較高，甚至有些電控零件比如噴油器更換後，要透過原廠電腦診斷儀器、網路與原廠有關部門，進行基本設定或初始化的設定。
(5)修理與維護時，所需專業性要更高，否則可能會被電擊或不必要的零件與人員損傷，比如拆開柴油高壓系統的零件之前，一定要先經過洩壓程序，因柴油噴射壓力高達1350bar，甚至 2000bar 以上。
(6)電腦控制零件如設計未週全時，可能容易造成電磁干擾，形成難以排除的引擎間歇性故障。
(7)購車成本較傳統式高。
(8)電腦控制共軌式柴油引擎的噴油壓力可高達1350bar，甚至 2000bar 以上，故其有關保養維修之技術和應注意事項與傳統式柴油引擎是不相同的。

VDIM does ...(恕刪)
同意! 翻了 VDIM 的相關資料, 的確是沒有提到這一點.
1. This vehicle is equipped with VDIM (Vehicle Dynamics Integrated Management). It is a concept of vehicle motion control that integrates brake control, drive force control and steering control.
2. Conventional vehicles use a combination of independent functions such as ABS, TRAC, VSC, EPS and VGRS. However VDIM integrates these systems to improve "drive, turn and stop", the motion performance of the vehicle in other words.
3. In conventional vehicles, control starts at the limit of the vehicle. However VDIM exercises control before the limit is reached, creating a smooth vehicle response. This expands the limits of the vehicle, and increases driving pleasure.
4. The VDIM manages all functions, such as the ABS with EBD, brake assist, the TRAC, and the VSC. It is operated by the Electronically Controlled Brake system, which regulates brake fluid pressure. The steering cooperative control function is also available. Thus the VDIM is able to perform comprehensive management.
5. Conventional brake control systems begin to control either the braking or motive force in order to stabilize the vehicle motion when it becomes unstable due to loss of tire traction. In contrast, in order to maintain stable vehicle control, the VDIM commences controlling the brake and steering systems in accordance with changes in balance before the vehicle becomes unstable. As a result, smooth vehicle control is achieved.
6. Conventional brake control systems manage all related functions, such as the ABS with EBD, brake assist, the TRAC and the VSC independently, according to the vehicle dynamics. In contrast, the VDIM provides smooth control by seamlessly integrating all those functions.
[以下是小弟推測, 因為有其他車友開 180KM/H 以上, 在換道之後就開進路邊的草叢裡了, 車報廢, 人沒事!]
樓主在前車急踩煞車的同時重踩煞車, 因為距離太近, 所以樓主向左打方向盤 (因為 ABS 沒有將輪胎鎖死, 所以可以轉方向盤), 企圖切到左線閃避前車 (因為在最外側車道), 可是因為速度太快 (撞到中央護欄的速度是 161KM/H, 所以當時的速度應該超過 161KM/H), 加上方向盤轉的角度太大 (因為 "高速的障礙物閃避訓練" 只是針對一般道路駕駛的訓練課程, 所以在高速下瞬間換道, 方向盤角度的拿捏很重要), 因此車輛往左偏撞向中央護欄 (輪胎可能也有關係).
如果樓主在第一時間有重踩煞車 (data1 有記錄), 所以在撞擊中央護欄之前應該會有煞車痕跡, 可是從警方現場圖並沒有看到這一段?
