Two pre-season test sessions, held at Donington Park, were conducted on 23 to 25 August and 5 to 7 September 2016.[54] The test sessions saw quick times laid down throughout,[55] and marked the first usage of Michelin's new tyre compound in both dry and wet weather conditions.[56] Reigning champion Sébastien Buemi and Jean-Éric Vergne were the two fastest overall drivers on the third day of running; 1.5 seconds covered the field in terms of outright pace on a circuit almost twice the length of a standard ePrix track.[55]
