The race was won by the #31 team of Pipo Derani and Felipe Nasr, while the LMP2 class victory was taken by Patrick Kelly and Spencer Pigot, who were awarded the win after the #81 entry was disqualified for failing to meet drive time limits. The GTLM class was won by the #4 entry for Tommy Milner and Oliver Gavin, while Jack Hawksworth and Aaron Telitz secured their second consecutive class victory in GTD.[1]
Background
The race was just the second for the WeatherTech SportsCar Championship after returning from the pandemic-induced hiatus. The race was added to the schedule in May due to said pandemic, becoming the second race of the season at Sebring alongside the rescheduled 12-hour race.[2] Similarly to the previous round at Daytona, a limited number of fans were announced to be allowed into the track for the event. In late June, Cadillac was announced as the title sponsor of the event.[3] The race marked the beginning of the LMP2 overall championship, as their only previous race (the 24 Hours of Daytona) counted for the Michelin Endurance Cup exclusively. Similarly, the GTD class only scored points towards the WeatherTech Sprint Cup in this race, not the overall GTD championship.[4]
On July 10, 2020, IMSA released the latest technical bulletin regarding Balance of Performance for the race. However, no changes were made to any cars taking part in the event.[5]
A total of 29 cars took part in the event, up from 26 cars in the previous round, thanks in part to the inclusion of the LMP2 class which was absent from the Daytona race.[7] There were 8 cars in the DPi class, 8 cars in the LMP2 class, 6 cars in the GTLM class, and 10 cars in the GTD class. The DPi field was unchanged in terms of entries from the previous event, although Felipe Nasr returned after missing the previous race due to testing positive for COVID-19. Stephen Simpson also replaced Chris Miller in the #85. Patrick Kelly replaced Simon Trummer in the #52 due to travel restrictions, and Gustavo Menezes was announced to run in the #81, making his first IMSA start since 2018. The two Meyer Shank RacingAcuras were absent from the event due to the round only scoring points towards the WeatherTech Sprint Cup.[8]
Practice
There were two practice sessions preceding the start of the race on Saturday, one on Friday and one on Saturday morning. The first session on Friday night lasted one hour and the second on Saturday morning lasted 75 minutes.[9]
Saturday's afternoon qualifying was broken into three sessions, with one session for the DPi and LMP2, GTLM, and GTD classes, which lasted for 15 minutes each, and a ten minute interval between the sessions.[9] The rules dictated that all teams nominated a driver to qualify their cars, with the Pro-Am (LMP2/GTD) classes requiring a Bronze/Silver Rated Driver to qualify the car. The competitors' fastest lap times determined the starting order. IMSA then arranged the grid to put DPis ahead of the LMP2, GTLM, and GTD cars.[22]
1 The No. 8 Tower Motorsport by Starworks entry was moved to the back of the LMP2 field as per Article 40.1.4 of the Sporting regulations (Change of starting tires).[22]
Race
Post-race
In DPi, Briscoe and van der Zande moved to first after being second coming into Sebring. Jarvis and Nunez dropped from first to second while Derani advanced from seventh to fifth.[28] Since it was the season's first points paying race, Kelly and Pigot led the LMP2 Drivers' Championship with 35 points.[28] As a result of winning the race, Gavin and Milner advanced from sixth to fourth in the GTLM Drivers' Championship. Jordan Taylor and Antonio García moved to first after being second coming into Sebring while Bamber and Vanthoor dropped from first to second.[28] GTD drivers, teams, and manufactures did not score full season points due to the event only counting towards the WeatherTech Sprint Cup. Cadillac kept their advantage in the DPi Manufactures' Championship while Chevrolet took the lead of the GTLM Manufactures' Championship.[28] Konica Minolta Cadillac DPi-V.R and Corvette Racing took the lead of their respective Teams' Championships while PR1/Mathiasen Motorsports became the leaders of the LMP2 Teams' Championship with eight rounds remaining.[28]
