From different sources we at Iepieleaks hear that the news is about new Paccar engine versions with more power. The new engine versions can be seen as the next Euro-6 generation of DAF. Rumours say all engines get a litle more Hp, and there is going to be an impressive new top version of the MX13 engine, maybe even with two turbochargers.
Other news that DAF sent out already is the new climatisation unit. This looks like a real improvement for the interior of the DAF cabs. This photo was taken from an official Instagram photo of DAF Trucks!
