A Dutch Iepieleaks spie reacted to my posting with a DAF CF Euro 6. He had two of them on a photo. One is a Jansen truck, and that company is also testing a Euro 6 DAF XF. You can see the big Euro 6 unit on the frame, but the rest seems to be the same as on every CF.
The registration of this truck shows that it was put on the road in september 2011 and it has the new 10,8 liter MX engine with 435 Hp!
The other one is a truck of Snel Transport, and i don’t see anything on this one but my source knows for shure that this is also a DAF fieldtest truck, testing the Euro 6 engine.
