The 2023 12 Hours of Sebring (formally known as the 71st Mobil 1 Twelve Hours of Sebring Presented by Advance Auto Parts) was an endurance sports car race held at Sebring International Raceway near Sebring, Florida from 15 to 18 March 2023. It was the second round of both the 2023 IMSA SportsCar Championship and the Michelin Endurance Cup. Cadillac Racing entered as the defending overall winners of the 12-hour event, albeit in the new-for-2023 GTP class rather than DPi.
The race was won by the #31 Whelen Engineering Racing entry, driven by Pipo Derani, Jack Aitken, and Alexander Sims, after a late accident eliminated the top three GTP-class cars.[1]
