In 2013, Davidson continued driving with Toyota for a full season and ended with third place in the drivers' championship and 2nd place at Le Mans with teammates Buemi and Sarrazin. For the 2014 season he remained with the Toyota works team and drove Toyota's new car, the Toyota TS040 Hybrid. During the year he won four races and finished third in the 2014 24 Hours of Le Mans, and became 2014 World Endurance Drivers' Champion alongside co-driver Sébastien Buemi. The following two years were less successful, yielding only two third-place finishes and championship finishes in fifth in 2015 and eighth in 2016.
