International Motor Sports Association's (IMSA) president Scott Atherton confirmed the race was part of the schedule for the 2018 IMSA SportsCar Championship (IMSA SCC) in August 2017.[1] It was the fifth consecutive year it was part of the IMSA SCC, and the 66th 12 Hours of Sebring.[1] The 24 Hours of Daytona was the second of twelve scheduled sports car endurance races of 2018 by IMSA, and the second of four races of the North American Endurance Cup (NAEC).[1] It was held at the 17-turn, 3.741-mile (6.021 km) Sebring International Raceway in Sebring, Florida on March 17, 2018.[1]

On March 1, 2018, IMSA released a bulletin outlining the minimum refueling times for all the classes.[2] All cars in the Prototype class were given 30 second minimum refueling time while GTLM and GTD were given times of 34 and 40 seconds, respectively. The times were made to override any refueling restrictor size following Montaplast by Land-Motorsport's penalty at Daytona.[3]

After the 24 Hours of Daytona 7 weeks earlier, Filipe Albuquerque, João Barbosa, and Christian Fittipaldi were leading the Prototype Drivers' Championship with 35 points.[4] GTLM was led by Ryan Briscoe, Richard Westbrook, and Scott Dixon with a three-point advantage over Joey Hand, Dirk Müller, and Sébastien Bourdais.[4] In GTD, the Drivers' Championship was led by Mirko Bortolotti, Rik Breukers, Rolf Ineichen, and Franck Perera with 35 points.[4] Cadillac, Ford, and Lamborghini were leading their respective Manufacturers' Championships, while Mustang Sampling Racing, Ford Chip Ganassi Racing, and GRT Grasser Racing Team each led their own Teams' Championships.[4]

On March 7, 2018, IMSA released the latest technical bulletin outlining Balance of Performance for the event.[5] In the Prototype class, the Acura ARX-05 received a reduction of turbo boost and a fuel capacity reduction of 1 liter while the Nissan Onroak DPi got a turbo boost reduction between 6000-7600 rpm. The Cadillac DPi-V.R received a 10 kilogram weight increase while the Mazda RT24-P received a fuel capacity increase of 2 liters and adjustments to the cars rear wing. In the GTLM class, the BMW M8 GTE received a 20 kilogram weight reduction and increase of power between 5000-7500 rpm while the Porsche 911 RSR got a fuel capacity increase of 2 liters. In the GTD class, the Mercedes-AMG GT3 received a 20 kilogram weight increase and a 1mm air restrictor increase while the Lexus RC F GT3 received a 1mm air restrictor increase.

Qualifying edit

 
Tristan Vautier (pictured in 2015) took the overall pole position for Spirit of Daytona Racing.

Friday afternoon's 65-minute qualifying session was divided into three groups.[13] All three categories had 15-minute individual sessions, and regulations stipulated teams to nominate a single driver to qualify their cars. The competitors' fastest lap times determined the starting order with the grid arranged to put the Prototype and GTLM cars ahead of all GTD entries.[22]

The first was for cars in GTD class. Daniel Serra qualified on pole for the class driving the #51 car for Spirit of Race, beating Christopher Mies in the #29 Montaplast by Land-Motorsport car by over five tenths of a second.[23]

The second session of qualifying was for cars in the GTLM class. Connor De Phillippi qualified on pole driving the #25 car for BMW Team RLL, beating James Calado in the #62 Risi Competizione car by less than one tenth of a second.[24]

The final session of qualifying was for the P class. Tristan Vautier qualified on pole driving the #90 car for Spirit of Daytona Racing, besting Olivier Pla in the #2 Tequila Patrón ESM entry.[25]
