The2023 12 Hours of Sebring (formally known as the71st Mobil 1 Twelve Hours of Sebring Presented by Advance Auto Parts) was anendurancesports car race held atSebring International Raceway nearSebring, Florida from 15 to 18 March 2023. It was the second round of both the2023 IMSA SportsCar Championship and theMichelin Endurance Cup.Cadillac Racing entered as the defending overall winners of the 12-hour event, albeit in the new-for-2023GTP class rather thanDPi.

International Motor Sports Association's (IMSA) president John Doonan confirmed the race was part of the schedule for the2023 IMSA SportsCar Championship (IMSA SCC) in August 2022.[2] It was the tenth consecutive year it was part of the IMSA SCC, and 71st 12 Hours of Sebring.[2] The 12 Hours of Sebring was the second of eleven scheduled sports carendurance races of 2023 by IMSA, and the second of four races of the Michelin Endurance Cup (MEC).[3] It was held at the 17-turn, 3.741-mile (6.021 km)Sebring International Raceway inSebring, Florida on March 18, 2023.[3]
2023 saw the introduction ofLMDh machinery into theIMSA SportsCar Championship andFIA World Endurance Championship, allowing teams in the top classes to compete in both marquee series on the same weekend. TheAcura ARX-06 ofMeyer Shank Racing withCurb-Agajanian claimed victory in the first race in class history, the2023 24 Hours of Daytona, and the car continued its early success by topping IMSA's sanctioned test that took place at Sebring approximately a month before the 12-hour event, albeit this time in the hands ofWayne Taylor Racing.[4] Former racing driver and Sebring Hall of Fame inducteeLyn St. James served as the race's grand marshal.[5]
The "Super Sebring" weekend also presented the opportunity for a number of drivers in other classes to compete in both endurance events in the same weekend. TheIron Dames trio ofMichelle Gatting,Rahel Frey, andSarah Bovy, for instance, competed in both theGTE Am category of the1000 Miles of Sebring as well as theGTD class in the 12-hour.[6] A total of 27 drivers pulled double duty across the two races, with onlyDane Cameron andMichael Christensen running in the top class for both.[7]
After the24 Hours of Daytona 5 weeks earlier,Tom Blomqvist,Colin Braun,Hélio Castroneves, andSimon Pagenaud were leading the GTP Drivers' Championship with 385 points.[8] However, on March 8, 2023,Meyer Shank Racing withCurb-Agajanian were penalized for manipulating tire pressure data during the Daytona race. As a result, the team lost its lead in the GTP championship standings, received a 200-point penalty, lost all team and driver Michelin Endurance Cup points, and forfeited race prize money.[9] After the penalty was applied,Filipe Albuquerque,Ricky Taylor,Louis Delétraz, andBrendon Hartley took the lead in the GTP Drivers' Championship with 350 points whileWTR withAndretti Autosport took the lead in the GTP Teams' Championship.[10]Jules Gounon,Daniel Juncadella,Maro Engel, andCooper MacNeil led the GTD Pro Drivers' Championship.[10] In GTD,Roman De Angelis,Marco Sørensen,Ian James, andDarren Turner led the Drivers' Championship with 375 points.[10]Acura,Mercedes-AMG, andAston Martin were leading their respective Manufacturers' Championships, whileWeatherTech Racing, and Heart of Racing Team each led their own Teams' Championships.[10] LMP2 drivers and teams as well as LMP3 drivers and teams would be scoring their first championship points of the season due to Daytona only counting towards the Michelin Endurance Cup championship.
On March 8, 2023, IMSA released the latest technical bulletin outliningBalance of Performance for the GTP andLMP2 classes.[11] Wholesale changes were introduced to the top class following the 24 Hours of Daytona, where all cars ran on equal metrics. All cars ran on a 1030 kilogram base weight at Daytona, whereas at Sebring theCadillac ran at the lowest weight (1038 kg), with theBMW at 1040 kg, thePorsche at 1048 kg, and the Acura at 1054 kg. As a result, the Cadillac and BMW both ran at 513 kilowatts of power, while the Porsche ran with 517 kW and the Acura with 520 kW – up from 500 kW across the board at Daytona. Maximum stint energy figures were also adjusted. No performance changes were announced for the LMP2 class.[12] On March 9, IMSA released the balance of performance metrics for the GTD class.[13] ThePorsche received a five millimeter increase to its air restrictor after suffering from a lack of straight-line speed at Daytona. This change marked a four millimeter increase from the Sebring test, after which several Porsche teams threatened to withdraw their entries from the series if BoP concerns were not addressed.[14] The new-for-2023Lamborghini also received an air restrictor size increase from 47 to 49 millimeters after suffering from a similar lack of pace in the opening round. TheFerrari received an increase in turbo boost pressure as well as a 15 kg weight increase, while theAcura also received similar changes in boost pressure but instead lost 15 kg. Other cars that received a weight break included theAston Martin,BMW,Corvette, andLexus, while theMercedes received an equivalent increase.[15]
Aside from the WEC support race, theMichelin Pilot Challenge and Porsche Carrera Cup North America made up the support bill. The former race was won byRobby Foley and Vin Barletta ofTurner Motorsport,[16] whileRiley Dickinson swept the pair of Carrera Cup events.[17]
A total of 53 cars took part in the event, split across five classes. 8 were entered in GTP, 8 in LMP2, 9 inLMP3, 8 in GTD Pro, and 20 in GTD.[18]

After initially committing to the Michelin Endurance Cup, SunEnergy1 Racing were also absent from the Sebring entry list, as were NTE Sport and the Iron Lynx #19. NTE Sport cited financial difficulties following their Daytona crash as the primary reason for their absence.[27]Julien Andlauer was also added to the #92 Kelly-Moss lineup. Inception Racing, which competed with theMcLaren 720S GT3 base model at Daytona, upgraded to theEvo specification for Sebring, giving the package its global race debut.[28]
