Mercedes introduced a raft of updates in Japan for the front wing, sidepod deflectors, and floor, aimed to increase efficiency against Ferrari's straight-line speed and Red Bull's overall downforce balance. This was noted to be the final updates of the season as Mercedes shifted focus to 2020, and while it did improve their competitiveness in the final rounds of the year, it was not a substantial increase in speed and its impact was masked by the extreme natures of the tracks and races in that part of the year. Mercedes took pole in only 2 races (United States and Abu Dhabi) after this upgrade's introduction, and won 4 races (Japan, United States, Mexico, and Abu Dhabi), two of which after starting from behind their rivals.
