The DAF XF105 is DAF Trucks’ heavyweight offering. Available from 18 to 44 tonnes GVW it was launched in 2005 in time for the Euro 4 standards. It replaced the XF95 with which it shares the same basic cab structure – a design originally launched in 1987. The XF105 production lasted until the end of 2013 when it was replaced by the Euro 6 version – simply called the XF. DAF dropped the ‘105’- type numbering from the model and concentrated purely on the horsepower of the truck (like many other manufacturers at the time). The new XF models are simply XF460 for example. If you absolutely need a Euro 6 truck then is has to be a new shape XF – if a Euro 5 EEV (2008 and newer) then an XF105 will do. If you are looking at trucks around 2011, then check that it has the revised MX engine in it – there were revised pistons and improved fuel injection and changes to the exhaust manifold that improved fuel performance. In 2011 you could also buy an ultra efficient version – the ATe – these should be worth a premium in the used market if you can find one.
