A question for the Apex ... using their powerful resources ... after watching Seb V slice through the field ...who are the all time top 5 (per the OTdb) in passing execution at Barcelona ...
Not a full answer to your question but we have seen these performances with 8 overtakes or more in recent years:
Heidfeld, 2011, 12 overtakes (started 24th, finished 8th)
Kobayashi, 2011, 10 overtakes (started 14th, finished 10th)
Hamilton, 2012, 10 overtakes (started 24th, finished 8th)
Sutil, 2011, 8 overtakes (started 17th, finished 13th)
Webber, 2013, 8 overtakes (started 7th, finished 5th)
Vettel, 2014, 8 overtakes (started 15th, finished 4th)
I don't think the overtaking page has breakdowns for number of overtakes by each driver before the mid 2000s, but looking at the overall totals I think it's unlikely there are any/many more after 1992.
