Also from the 2018 video you can see how badly Lewis went wide in Radillon ....that is what made it look such an easy pass. Channel 4 Karun Chandok picked it up when it happened.
Exactly. In 2017, Vettel was already much closer through Eau Rouge and Raidillon and couldnt build up the speed difference needed for a pass. He had to get out of the slipstream with a much smaller speed delta.
In 2018 Vettel was further away on the way down to eau rouge but already started gaining very quickly through Raidillon and managed the pass with the speed difference. Probably partly due to Hamilton going wide, partly due to a stronger power output at that moment. And yes, the power units this year play a role, too. Merc is not faster any more on the straights like last year. But that is not the only reason Vettel could pass Hamilton at that point.
Also, looking at this picture
