## Background

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. It was the fifth consecutive year it was part of the IMSA SCC, and the 66th 12 Hours of Sebring. 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). It was held at the 17-turn, 3.741-mile (6.021 km) Sebring International Raceway in Sebring, Florida on March 17, 2018.
On March 1, 2018, IMSA released a bulletin outlining the minimum refueling times for all the classes. 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.
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. GTLM was led by Ryan Briscoe, Richard Westbrook, and Scott Dixon with a three-point advantage over Joey Hand, Dirk Müller, and Sébastien Bourdais. In GTD, the Drivers' Championship was led by Mirko Bortolotti, Rik Breukers, Rolf Ineichen, and Franck Perera with 35 points. 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.

## Qualifying

Friday afternoon's 65-minute qualifying session was divided into three groups. All three categories had 15-minute individual sessions, and regulations stipulated teams to nominate a single driver to qualify their cars.

## Race
### Start and early hours

At the start of the race at turn 1, Vautier and Pla had a collision that led to Pla needing to pit during the next lap of the race. In addition to this, both Milner and Serra both got tire punctures and also needed to pit. Around twenty minutes into the race, Saavedra spun around the final corner and was hit by Montecalvo who was flipped over following a hit to the tirewall. Just before the four hour mark, an awning blew onto the track bringing out the yellow flag. Almost immediately after the caution ended however, Brundle spun during the final turn.

### Afternoon

At the beginning of the afternoon, a Lexus hit a wall which caused debris to spread onto the track. This led to a caution period which caused Derani to lose his seventeen second lead. Just after the restart, an Acura retired due to an oil pressure problem. Towards the six hour mark, Fittipaldi and Nasr were involved in a collision that sprung from Nasr diving towards Fittipaldi. The collision led to Fittipaldi being spun around but rejoining the track shortly after. Around the halfway mark, Vautier was given a drive through penalty after hitting Montoya which led to his retirement. Later, there was another collision between van der Zande and Curran which lead to tire debris being torn off and causing another yellow flag. Before the end of the afternoon, Barbosa and French had a collision that led to the two falling multiple laps behind the leader.

### Sunset to finish

At the beginning of the afternoon, Bruni hit a curb which led to his diffuser landing on the track. This brought out another yellow flag however after the flag the Porsche managed to maintain third place. Just before the end of the race, while in second, Pigot had attempted to drive between Vautier and the wall which led to him hitting debris and lose multiple places.
