2019 1000 Miles of Sebring

The provisional calendar for the 2018-19 FIA World Endurance Championship, released on 1 September 2017 saw a raft of changes, with several races dropped, but included a return to Sebring for the first time since 2012.  In the provisional calendar issued, the race was originally planned to be run as a second 12-hour race after the IMSA Mobil 1 12 Hours of Sebring on the same weekend, and would start at midnight after the conclusion of the IMSA 12 hours.^[1][2] On 21 September 2017, the race became known as the 1500 Miles of Sebring, to avoid confusion between the 2 events, at the FIA World Motor Sport Council meeting in Paris.^[3] However, on 4 April 2018, it was announced that the race would become shortened to 1000 Miles or 268 laps, have a time limit of 8 Hours, and would take place on March 15 instead, prior to the start of the 12 Hours of Sebring, rather than after the race. In addition, it was also announced that there would be a new pitlane built to accommodate the WEC teams, located on the Ulman Straight.^[4][5]

The entry list released on 8 February 2019 saw a number of changes, with the #4 ByKolles Racing Team ENSO CLM P1/01 removed, after the team announced they would not compete due to an engine supply dispute with NISMO, and an additional Entry from the Corvette Racing team. Nathanael Berthon was added to the #3 Rebellion Racing Rebellion R13, while Mathias Beche moved to the #1, replacing Andre Lotterer, who was unable to attend due to a clashing simulator test for the DS Techeetah Formula E team. Jenson Button and Matevos Isaakyan were replaced in the #11 and #17 SMP Racing BR Engineering BR1s by Brendon Hartley and Sergey Sirotkin respectively.^[6][7]
