While pondering an overtake on Buemi, slower traffic delayed the two, causing di Grassi to drop back.[91][92] Di Grassi was also awarded FanBoost; he could not use it because of battery voltage limitations.[95] He drew closer to Buemi on the final lap and forced the latter to defend his position, as he could not find the space to get ahead as the run to the start/finish line was not long enough. It allowed Buemi to repel di Grassi,[91][5] for his fourth win of the season,[94] and the tenth of his career.[96]
