No, at least not yet. Maybe in the future.
From my ETS2 long haul experience I expect it to take around 4 to 5 hours real time. You can drive roughly 1000 km per hour. The longest job I drove on the base map + dlcs was Palermo (IT) to Vyborg (RU) with ~3780km And that took around 3 hours and 20 minutes.
Obviously in PT, ES, FR and DE you are going to drive a bit more than that per hour on average, but in the baltics you are being slowed down a bit.
