在富士速度不佳的保时捷在上海6小时周五练习里恢复强劲速度。哈特利在上午做出1分46.781秒的最快圈速，领先奥迪8号车组卢卡•迪格拉西创下的时间快了0.198秒。下午赛道温度上升后，新西兰人将自己设下的标杆提高了二秒之多，而卫冕冠军车组是当天唯一将时间做到1分44秒的赛车。

奥迪8号车在下午练习结束后，维持当天第二快，而且依然由罗伊科克•杜瓦尔做出，但仍距离1号车组1.617秒。

车手积分榜上处于领先的保时捷2号车组因为更换电池而错过了第一节练习的大部分时间，下午返回赛道后，由马克•列布做出1分46.264秒，与杜瓦尔的时间仅相差0.053秒，为当天第三快。

上一场在富士主场获得2014年以来首胜的丰田，由安东尼•戴维森做出车队周五的最快时间1分46.812秒，虽然落后保时捷的标杆多达2.2秒，但位居奥迪7号车之前。不过，上一场获胜的丰田6号车为LMP1-H组最慢。

LMP1组方面，4号车Bykolles比Rebellion稍快，两台赛车相差0.627秒。

LMP2组的圈速方面，G-drive继续独占鳌头，26号赛车在下午跑出1分54.627秒。马诺经历了上午的调整后，在下午由44号车突破1分55秒大关，以0.229秒之差居次席。同队的45号赛车则第三快。

主场作战的DC Racing在下午遇到困难，圈速不如上午排名同组别第五时理想，排名最后。

法拉利继续在GTE-Pro一马当先，两辆AF Corse赛车包揽当天该组别最快圈速，福特66号赛车列第三。
