The wild, strange, and bizarre 2020 IMSA WeatherTech Sportscar Series season comes to a conclusion this weekend at Sebring International Raceway, where more champions will be crowned. After a 2 1/2 hour race on the circuit earlier this year in July, teams and drivers will wrap things up in Florida with the 68th Annual Mobil 1 Twelve Hours of Sebring.

There are 31 cars across four different classes that will hit the pavement, with some championships already being decided. PR1 Mathiasen Motorsports’ Patrick Kelly is the 2020 Drivers’ champion in the LMP2 class. In GT Le Mans, it is Corvette Racing’s Jordan Taylor and Antonio Garcia taking the crown. Once the team takes the green flag on Saturday, Corvette will also claim the Manufacturer’s championship. All eyes will be on the two remaining classes this weekend.

The top class, Daytona Prototype Internationals, has a heavyweight fight on their hands. The No. 7 Acura Team Penske DPi holds a two-point lead over Wayne Taylor Racing’s No. 10 Cadillac heading into the event. Once the checkered flag waves, a number of changes will commence with Penske’s exit from DPi, Mazda’s reduction to a single car, WTR converting to Acura, and Meyer Shank Racing moving up from GT Daytona to DPi with a second Acura.

Looking at the GTLM class, Meyer Shank Racing’s No. 86 Acura NSX GT3 holds a comfortable lead (17 points) over the No. 16 Wright Motorsports Porsche 911 GT3 and 18 points ahead of the No. 14 AIM Vasser Sullivan Lexus RC F GT3. Like the DPi class, there will be numerous changes once this race ends. Among them are the departure of the Porsche GT Team, and just a part-time schedule next season for BMW Team RLL.

The usual IndyCar faces will once again be on hand for the endurance race in the Sunshine State, including Florida native Sebastien Bourdais in the No. 5 Cadillac DPi with Mustang Sampling Racing / JDC-Miller MotorSports. Simon Pagenaud will return to the No. 6 Acura Team Penske with Juan Montoya and Dane Cameron, while Alexander Rossi looks to win a championship with Helio Castroneves and Ricky Taylor in the No. 7 entry.

Scott Dixon aims for another championship as he rejoins Wayne Taylor Racing teammates Ryan Briscoe and Renger van der Zande in the No. 10 Konica Minolta Cadillac. Ryan Hunter-Reay will pair up with Jonathan Bomarito and Harry Tincknell once again in the No. 55 Mazda Motorsports machine.

Colton Herta will make his final IMSA start of the season for BMW Team RLL after an outstanding sophomore season in IndyCar, where he finished 3rd in the final standings. He returns to the No. 25 BMW M8 GTE with Connor De Phillippi and Bruno Spengler in GTLM. Another young phenom in Kyle Kirkwood will be back in the GTD class with AIM Vasser Sullivan. He will be driving the No. 14 Lexus RC F GT3 with Jack Hawksworth and Aaron Telitz.
