在欧洲牵引车市场,达夫和奔驰是并驾齐驱的两个排头兵,两家都在争抢第一的位置。现在,奔驰凭借令人难忘的Actros博取运营者们的赞誉,它有新的发动机和一个充满魅力讲究的驾驶室。而达夫则是选择了演变而不是彻底变革,他们相信凭借对XF105的提升变型即有能力在2013年底欧Ⅵ全面生效时抵挡Actros、沃尔沃FH以及其它制造商的挑战。尽管能看出新XF同目前的车型有所不同,但并没逃离这样一个事实:它仍是基于可以追溯到1987年驾驶室框架之上的另一个新版本。不过,达夫改变了许多不显眼的主要部件,包括底盘,现在它的主车架前部逐渐向外加宽,以容纳更宽的散热器。现在12.9L的MX发动机采用EGR和SCR来满足欧Ⅵ的NOx排放限制,需要提高发动机冷却能力来应对更高水平的废气排放。另外还有新的前后桥和悬架系统。它们被设计成适合2.55m的全宽限制,而之前是2.5m,并且比它们的前代产品要轻。达夫称上述以及其它方面的重量节省意味着欧ⅥXF比欧Ⅴ型车辆的重量增加不会超过90kg,而
In the European tractor market, Duff and Mercedes-Benz are the two vanguard in keeping pace with the competition, both are vying for first place. Now, Mercedes-Benz gains praise from operators with its unforgettable Actros, its new engine and a captivating cab. Instead, Duff chose evolution rather than radical change, believing that the upgrade to the XF105 was able to withstand the challenges of Actros, Volvo FH and other manufacturers by the time Euro VI came into full force by the end of 2013. Although it can be seen that the new XF is different from the current model, it does not escape the fact that it is still based on another new version that dates back to the 1987 cab frame. However, Duff has changed many unobtrusive main components, including the chassis, and now its main frame front gradually widened to accommodate a wider radiator. Now 12.9L MX engine with EGR and SCR to meet the Euro VI NOx emission limits, the need to improve the engine cooling capacity to deal with higher levels of emissions. In addition there are new front and rear axle and suspension system. They are designed to fit the full width limit of 2.55m, up from 2.5m and lighter than their predecessor. Duff said the above and other aspects of the weight savings means that the Ⅵ XF than the Euro V vehicle weight increase will not exceed 90kg,
