The 4 Hours of Le Castellet will serve as the first of six rounds on the 2019 calendar, with 41 cars and 111 drivers at the start on Sunday 14 April. This diverse field will amount to the largest number of LMP2 prototypes on track - outside the 24 Hours of Le Mans - and includes the top competitors in endurance racing.
- LMP2: 18 cars, the biggest grid in this class in the history of the ELMS
- LMP3: 14 cars, including all class competitors from 2018 in their quest for the European title
- LMGTE: 9 cars, with all eyes on Kessel Racing's #83 Ferrari and its all-female driver line-up of Manuela Gostner, Rahel Frey and Michelle Gatting. They are currently in preparations for the 24 Hours of Le Mans on 15-16 June!
