Theissen: BMW Sauber undecided on diffuser changes

BMW Sauber boss Mario Theissen says his team have not yet finalised what modifications they will make to their car’s rear diffuser in light of last week’s FIA decision declaring double-decker designs legal.

BMW Sauber 車隊領隊 Mario Theissen 表示，在上禮拜 FIA 宣布雙層擴散器的合法性後，他們還沒決定會在賽車的後擴散性上做哪些修改。

Theissen was vocal in his opposition to the designs being run by Brawn, Toyota and Williams, but says he accepts the FIA decision. However, while the likes of Renault and McLaren already had revised diffusers on their cars in China, BMW Sauber are taking a more circumspect approach. 

Theissen 在自己的立場上對布朗GP、威廉斯、豐田車隊使用的設計發表意見，但是他也說他接受 FIA 的決議。然而，如雷諾和麥拉倫車隊在中國站已經推出修改後的擴散器，BMW Sauber 車隊的用更小心謹慎的態度來處理。

“The diffuser is the rear end of an entire aero package beneath the car,” Theissen told the team’s official website. “The concept is complex and only works if all the components up-stream - in the front area of the car - also are fully integrated. 

"擴散器是影響整部車的空力套件的收尾部份"，Theissen 在車隊官網上表示。"概念很複雜，而且只有在所有套件的起頭 -車子的前面部份是能一體配合的才能發揮作用"。

“At the end of the day, it takes a far bigger effort than just copying a component and fitting it to the car. To channel the airflow beneath the car to the rear in a way that a double-decker design diffuser really produces more downforce, the entire aero package - from the front wing to the rear - has to be fully revised.”

"要做的努力不只是複製零件然後裝上車子而已，開洞引導氣流的雙層底板設計的確製造更多的下壓力，整台車的空力從頭到尾都要再重新修改"。

Like most of the seven teams running single-deck diffusers, BMW Sauber began work on a revised design several weeks ago. Despite this, they are yet to decide whether it will be incorporated into the revised aero package they are planning for next month’s Spanish Grand Prix.

如其他使用單層底板的七支車隊，BMW 幾週前就開始修改設計，儘管如此，他們尚未決定雙層底板是會放進他們未下個月西班牙站的空力套件裡。

“This work represents an interplay between our design department and the aerodynamicists,” explained Theissen. “Our staff in Munich and Hinwil are working flat-out. As planned, we will travel to Barcelona with a new aero package. Nonetheless, it has not yet been determined to what extent a modified diffuser solutions will be integrated there.”

"這項研發顯露了我們設計部門和空力學家之間的互相的影響"，Theissen 解釋說。"我們在慕尼黑和 Hinwil 的人員都日以繼夜的工作。依照計畫，在巴塞隆納我們會有新的空力套件。但是，還沒有估計出擴散器在這套件中會有多大的修改"。

BMW Sauber have experienced a tough start to their 2009 campaign, scoring just four points from the opening three races, putting them fifth in the constructors’ standings.

BMW 車隊已經經歷了一個艱困的2009年賽季開季，前三場比賽只得了三分，在車隊競爭中排名第五。
