Daytona International Speedway in 2015

NASCAR founder Bill France Sr., who built the Daytona International Speedway in 1959, conceived the 24 Hours of Daytona as a race to attract European sports car endurance racing to the United States and provide international exposure to Daytona.[1] It is informally considered part of the "Triple Crown of Endurance Racing" with the 12 Hours of Sebring and the 24 Hours of Le Mans.[2]

International Motor Sports Association's (IMSA) president Scott Atherton confirmed the race was part of the schedule for the 2018 WeatherTech SportsCar Championship in August 2017.[3] It was the fifth consecutive year it was part of the WeatherTech SportsCar Championship, and the 56th 24 Hours of Daytona.[3] The 24 Hours of Daytona was the first of twelve scheduled sports car endurance races of 2018 by IMSA, and the first of four races of the North American Endurance Cup.[3] It took place at the 12-turn 3.56 mi (5.73 km) Daytona International Speedway combined road course in Daytona Beach, Florida, on January 27–28.[3][2]

Entry list

Fifty cars were officially entered for the 24 Hours of Daytona with the bulk of entries in the Prototype and Grand Touring Daytona (GTD) categories.[4] The 2017 race winner, Wayne Taylor Racing, returned to defend their title.[5] Three existing teams, Action Express Racing, Spirit of Daytona Racing and Extreme Speed Motorsports, each fielded two Daytona Prototype International (DPi) cars called Cadillac DPi-V.R and Nissan Onroak DPi. Wayne Taylor sent a solitary Cadillac DPi-V.R chassis to the race.[6] Penske Racing made their full-time sports car racing competition comeback for the first time since the 2009 Rolex Sports Car Series. They fielded a pair of Honda-powered Acura ARX-05 DPis for 2018.[7] Mazda returned to sports car racing after withdrawing with three races left in the 2017 season so their duo of RT24-Ps could be re-engineered by German outfit Team Joest.[8] They were joined by ten global-specification Le Mans Prototype 2 (LMP2) cars, represented by three out of the four major chassis: six Oreca 07s entered by JDC-Miller MotorSports, Jackie Chan DCR JOTA (two each), Performance Tech Motorsports, CORE Autosport (one each). a trio of Ligier JS P217s utilised by PR1/Mathiasen Motorsports (one) and United Autosports (two), and one Riley Mk. 30 from BAR1 Motorsports.[4][9]

Fernando Alonso, the two-time Formula One World Champion (pictured in 2016) made a one-off appearance for United Autosports for Daytona.

After the aging Prototype Challenge class was retired after 2017 due to declining interest from teams,[10] Grand Touring Le Mans (GTLM) was made the highest-ranking class below the Prototype category in the WeatherTech SportsCar Championship. Nine cars from five manufacturers were entered for Daytona.[5] The BMW M8 GTE made its racing competition debut at the track; Team RLL entered two chassis for the season.[11] Porsche fielded two 911 RSRs for the second successive season, and Chip Ganassi Racing entered their two Ford GTs for the third consecutive year.[12] Ferrari aligned with Risi Competizione for one 488 GTE.[12] Corvette Racing transported their aging duo of C7.Rs to Daytona.[10] GTD composed twenty-one cars amongst eight GT3 manufacturers.[6] Ferrari was the most represented marque in the category with four 488s: two by Scuderia Corsa and one each from Spirit of Race and Risi Competizione.[5][10] A mix of teams and automotive brands made up the rest of the GTD field. These included two GRT Grasser Racing Team-entered Lamborghini Huracáns with a third by Paul Miller Racing, and a trio of Riley Motorsports-entered Mercedes-AMGs. Michael Shank Racing and HART entered three Acura NSXs and a trio of Porsche 911 Rs with one each from Park Place Motorsports, Wright Motorsports and Manthey Racing. Other cars fielded were a duo of Audi R8 LMS from Magnus Racing and Land Motorsport, two Lexus RC Fs by 3GT Racing and a BMW M6 from Turner Motorsport.[9]

Each car was driven by two drivers who contested the entire WeatherTech SportsCar Championship. They were joined by one North American Endurance Cup racer and one or two extra drivers.[13] These additional participants were recruited from a variety of racing categories, including the FIA World Endurance Championship (such as Gustavo Menezes for JDC-Miller MotorSports), the Deutsche Tourenwagen Masters (such as René Rast for Mazda Team Joest), and the IndyCar Series (such as Ryan Hunter-Reay for Wayne Taylor) among others.[14] Some drivers competed at Daytona on a one-off basis, such as Fernando Alonso, a two-time Formula One World Champion,[15] Williams driver Lance Stroll and Formula E racers Felix Rosenqvist and António Félix da Costa.[16] A. J. Allmendinger, Justin Marks, Brendan Gaughan and Austin Cindric from NASCAR,[17] and 2017 Formula Three European Champion Lando Norris entered the event.[18] Stuart Middleton won the Sunoco Whelen Challenge by taking the GT4 category title in his debut year in the British GT Championship, earning him a seat with Action Express Racing.[19]

Pre-event balance of performance changes

The week before the official three-day test session at the circuit, IMSA altered the balance of performance in all three categories to create parity in the classes. 10 kg (22 lb) of weight was added to the Cadillac DPi-V.Rs compared to 2017 but the decrease of handling abilities was countered by having the car's top speed raised by having its air restrictor increased by 1.8 mm (0.071 in). The duo of Nissan Onroak DPis and the two Acura ARX-05s had their weight increased to 940 kg (2,070 lb) to lower their performance, 10 kg (22 lb) more than the LMP2 chassis and the pair of Mazda RT24-Ps. The Nissan and Mazda engines were not altered because IMSA was satisfied with their performances, but the series changed the aerodynamic packages on some Prototypes which affected their handing abilities. The debuting BMW M8 GTE's weight was established at 1,250 kg (2,760 lb) and its turbocharger boost curve was revised over its predecessor, the BMW M6 GTLM. The Mercedes-AMG GTD car had its top speed raised slightly with the enlargement of its air restrictor by 1 mm (0.039 in).[20]

Testing

Felipe Nasr (pictured in 2015) set the fastest overall lap time in testing for Action Express Racing's concluding day.

All 50 entries were involved in three days of testing divided into seven sessions held at the circuit from January 5–7.[21] João Barbosa set the fastest time early in the first day's running with a time of 1 minute and 37.266 seconds for the No. 5 Mustang Sampling Racing Cadillac.[22] Co-driver Filipe Albuquerque later improved in the second session to a 1-minute and 37.196 seconds lap.[23] The fastest LMP2 lap came from Colin Braun's No. 54 CORE Oreca who was second-fastest overall. The No. 10 Wayne Taylor Cadillac of Renger van der Zande was third.[23] Tristan Vautier set the fourth-fastest lap time for Spirit of Daytona in its No. 90 Cadillac. Ho-Pin Tung in the No. 78 Jackie Chan Oreca 07 rounded out the top five.[24] Laurens Vanthoor led GTLM in the No. 912 Porsche 911 RSR with a 1-minute and 44.065 seconds lap in the second session, and teammate Nick Tandy's sister car was third. They were separated by Richard Westbrook's No. 67 Chip Ganassi Ford.[25] GTD was topped by the No. 11 Grasser Lamborghini of Rolf Ineichen and later Franck Perera. They were ahead of Matteo Cairoli's No. 59 Manthey Porsche.[23][24]

The second day's testing had Felipe Nasr lead in the No. 31 Action Express Cadillac at 1 minute and 36.793 seconds. Jordan Taylor improved Wayne Taylor's Cadillac best time to second. Albuquerue was slower than the day before and was third. Eddie Cheever III, driving the No. 90 Spirit Cadillac, was fourth-fastest by going faster lap co-driver Vautier in the day's second session. The No. 78 Jackie Chan Oreca was the highest-placed LMP2 car in fifth with Alex Brundle aboard. The No. 66 Chip Ganassi Ford of Sébastien Bourdais moved to the top of GTLM with a lap of 1 minute and 43.795 seconds in the fourth session. Gianmaria Bruni was second-quickest in the No. 912 Porsche. Ryan Briscoe put the sister No. 67 Chip Ganassi Ford in third, and Alessandro Pier Guidi's No. 62 Risi Ferrari was fourth-fastest. GTD was still led by the No. 11 Grasser Lamborghini courtesy of Ineichen's lap on the first day. Manthey's No. 59 Porsche remained second; driver Sven Müller improved its best lap time.[26][27]

The third and final day of testing featured a qualifying session to determine the locations of the team's pit stalls and garages for the race three weeks later.[28] Nasr's No. 31 Action Express Cadillac set the fastest overall testing lap time of all drivers with a 1-minute and 35.806 seconds effort. The second-fastest car was the No. 90 Spirit Cadillac of Vautier and Albuquerque putting the No. 5 Mustang Sampling Cadillac in third position. Wayne Taylor Racing placed fourth from a lap by Van der Zande and Dane Cameron completed the top five overall runners in the No. 6 Penske Acura ARX-05. Joey Hand set the fastest overall GTLM time in the No. 66 Chip Ganassi Ford with a 1-minute and 43.610 seconds lap. Oliver Gavin's No. 4 Chevrolet Corvette C7.R was second, followed by the sister No. 67 Ford GT driven by Briscoe. Ineichen's lap from the first day of testing was never bettered and the No. 11 Grasser Lamborghini remained the fastest GTD car. Cairoli's first session lap in the Manthey Porsche was fast enough to keep it second in class.[29]

After testing, IMSA adjusted the balance of performance for the second time in all categories after analysing data of the car's performances. The Cadillac DPi-V.Rs had their fuel capacity enlarged by 1 l (0.22 imp gal; 0.26 US gal) along with their refuelling restrictors by 0.5 l (0.11 imp gal; 0.13 US gal) but their air restrictors were 0.6 mm (0.024 in). The size of the fuel tanks in the Acura ARX-05 and the Nissan Onroak DPis were increased by 4 l (0.88 imp gal; 1.1 US gal) and 2 l (0.44 imp gal; 0.53 US gal) with the size of both car's fuel restrictors increased by 1.5 mm (0.059 in). Nissan Onroak DPis boost pressure was increased to peak at 7,100 rpm. The Mazda RT24-Ps were 15 kg (33 lb) lighter. Its rev limit was raised to 8,600 rpm and its air restrictor was lengthened by 0.5 mm (0.020 in). The Acura, Nissan and Mazda DPis gurney flaps were adjusted for aerodynamic purposes.[30]

All GTLM cars bar the Ferrari 488 GTE had the size of their fuel tanks adjusted. The Chevrolet Corvette's C7.R's top speed was lowered through rear wing angles alterations by two degrees, while the Ford GT's angles were increased by three degrees. The Porsche 911 RSRs performance was lowered as its fuel restrictors were reduced in size by 1 mm (0.039 in). In GTD, the Acura NSX GT3 lost 10 kg (22 lb) in weight and the Mercedes-AMG was made 15 kg (33 lb) heavier. Turbocharger adjustments were made to the Audi R8 LMS, Lamborghini Huracán, and the BMW M6 cars.[30]

Practice and qualifying

Four practice sessions were held before the start of the race on Saturday, three on Thursday and one on Friday. The first two one-hour sessions were on Thursday morning and afternoon. The third held later that evening ran for 90 minutes; the fourth on Friday morning lasted an hour.[31]

Rast's No. 77 Mazda set the fastest lap of the first practice session at 1 minute and 37.428 seconds, 0.007 seconds faster than Vautier's Spirit's No. 90 Cadillac. Jordan Taylor put the No. 10 Wayne Taylo Cadillac in third overall. Albuquerue placed the No. 5 Mustang Sampling car fourth. The highest-placed LMP2 car was Brundle's No. 78 Jackie Chan entry in fifth place.[32] Early in the session, Phil Hanson made an error on cold tires that put the front of the United Autosports Ligier into the turn five tire barrier.[33] Practice was red-flagged for 8 minutes and 49 seconds so his car could be removed from the circuit.[32] In GTLM, the No. 66 Chip Ganassi Ford of Hand led with a lap of 1 minute and 44.571 seconds. Alessandro Pier Guidi put the No. 62 Risi Ferrari second. Vanthoor in the No. 912 Porsche was third. Miguel Molina's No. 82 Risi car was fastest in GTD. Pedro Lamy set the second-fastest class lap in Spirit of Race's No. 51 entry.[32]

In the second practice session, Hélio Castroneves in the No. 6 Penske Acura ARX-05 recorded the fastest lap of the day with a 1-minute and 37.096 seconds effort. He was ahead of the No. 22 Extreme Speed Nissan of Nicolas Lapierre and Albquerque's No. 5 Mustang Sampling car. The leading LMP2 car was Colin Braun behind the wheel of the No. 54 CORE car in fourth. Jonathan Bomarito rounded out the top five in Mazda's No. 55 vehicle.[34] Patrick Pilet led GTLM in the No. 911 Porsche with a 1-minute and 43.902 seconds lap set late in the session. Jan Magnussen's No. 3 Corvette was second. Westbrook in the No. 66 Chip Ganassi Ford rounded out the top three in the category.[34] Álvaro Parente's No. 86 Michael Shank Racing Acura-NSX GT3 was fastest in GTD, while Molina was 0.242 seconds slower in the No. 82 Risi Ferrari.[35]

Renger van der Zande (pictured in 2016) took the overall pole position for Wayne Taylor Racing.

Thursday afternoon's 75-minute qualifying session was divided into three groups.[31] GTD cars were sent onto the track first for 15 minutes with a 10-minute interval before GTLM and Prototype entrants had two separate identically timed sessions. Regulations stipulated teams to nominate a single driver to qualify their cars. The competitors' fastest lap times determined the starting order. IMSA then arranged the grid to put the Prototype and GTLM cars ahead of the GTD field.[13] Van Der Zande for Wayne Taylor took the third pole position of his career,[36] on his final lap with a time of 1 minute and 36.083 seconds; he ran deep at turn five through later braking.[37] This was his team's first pole position at Daytona since Max Angelelli in the 2010 race.[36] He was joined on the grid's front row by Castroneves who had pole position for Penske in the closing minutes until Van der Zande's lap.[38]

On his final timed lap, Albuquerue qualified the No. 5 Mustang Sampling Cadillac in third place. Patricio O'Ward took fourth in the No. 38 Performance Tech Racing Oreca to become the field's highest-placed LMP2 car.[38] Early pace setter Vautier in Spirit's No. 90 car was fifth, and Robin Frijns' No. 78 Jackie Chan entry sixth.[37] An electrical fault left Nasr seventh.[39] Braun's No. 54 CORE car, Bomarito's No. 55 Mazda ninth, and Cameron's No. 6 Penske were eighth to tenth.[40] Lapierre set no lap time after he locked his brakes on his first timed lap and drove into the tyre barriers at the West Horseshoe. He damaged the No. 22 Extreme Speed car's front-left suspension.[37][41] Extreme Speed's No. 2 vehicle did not take part due to a precautionary engine switch.[38] Mazda's No. 77 car was absent because of a pre-qualifying data irregularity.[41]

Jan Magnussen (pictured in 2009) claimed pole position in the GTLM class for Corvette Racing.

In GTLM, Magnussen's No. 3 Corvette drafted his teammate Gavin and took his fourth class pole position in the series. He suppressed Hand's 2017 category lap record of the track with a time of 1 minute and 42.779 seconds. Magnussen was 0.019 seconds faster than Hand's No. 66 Ford in second place. Following in third was Vanthoor's No. 912 Porsche, with the sister No. 911 car of Pilet in fourth.[42] Westbrook completed the top five class competitors in the slower Ford.[38] Daniel Serra in the No. 51 Spirit of Race Ferrari 488 GT3 was the first driver to record a GTD lap time in the 1 minute and 46 second range midway through.[38][43] This secured him the second pole position of his career, and his first in any class since the 2016 Monterey Grand Prix with a 1-minute and 46.407 seconds lap. Molina made it an all-Ferrari category front row in the No. 82 Risi car.[42] The No. 11 GRT Lamborghini of Mirko Bortolotti was the third-fastest class qualifier. The car was demoted to the rear of the GTD field for failing a mandatory stall test in a post-qualifying technical inspection. Hence, Jack Hawksworth in the No. 15 3GT Racing Lexus RC F GT3 inherited third.[42] Alessandro Balzan's No. 63 Scuderia Ferrari started fourth, and Dominik Baumann's slower Lexus fifth.[38] Two GTD cars failed to record a lap time: The No. 73 Park Place Porsche tire punctured on its out lap, and P1's No. 73 Mercedes-AMG GT3 had brake problems.[44]

The third practice session ran at night and had Vautier's No. 90 Cadillac set the fastest overall lap of 1 minute and 37.210 seconds. Castroneves was almost two-tenths of a second behind in second, with the No. 22 Extreme Speed Nissan of Pipo Derani third. Harry Tincknell in the No. 55 Mazda placed fourth and Norris' quicker United Autosports car was fifth.[45] Kyle Masson caused the session's first stoppage when his No. 38 Performance Tech Oreca ran out of fuel on the track requiring recovery back to the pit lane. Later, Gustavo Menezes' No. 99 JDC-Miller car blew its right-rear tire entering turn six at high-speed. Though he controlled his car throughout and avoided hitting the wall, practice was stopped for 12 minutes.[46] Ford took the first two placings in GTLM with Bourdais faster than his teammate Westbrook by two-tenths of a second. Bortolotti's No. 11 Grasser Lamborghini Huracán led GTD, and Sam Bird, in the No. 64 Scuderia Ferrari, was second in class.[46]

Mike Conway led the last practice session in the No. 31 Whelen Engineering Racing entry with a time of 1 minute and 36.865 seconds. Stroll's No. 37 Jackie Chan car was second-fastest. The No. 90 Cadillac of Vautier set the third-quickest lap. Rast's No. 77 Mazda, along with Albuquerque's No. 5 Mustang Sampling entry completed the top five overall entrants.[47] Though the session passed relatively peacefully, the right-rear tire on the No. 32 United Autosports vehicle driven by Bruno Senna blew on the track.[47][48] In GTLM, Hand once again went fastest in the class with a lap of 1 minute and 44.602 seconds. Bruni was second-fastest in the No. 912 Porsche, and his teammate Pilet placed third in the sister No. 911 car. Cairoli set the fastest time in GTD, followed by Jeroen Bleekemolen in the No. 33 Riley Mercedes-AMG GT3 car.[49]

Pre-race

Tomy Drissi withdrew from the race due to business commitments, leaving the No. 20 BAR1 Riley Mk. 30 to operate as a four-person entry.[50] The No. 2 Extreme Speed Motorsports, the No. 71 P1 Mercedes-AMG, and the No. 77 Mazda entries were sent to the rear of their respective class fields because their teams changed their respective starting drivers. Although Paul Miller Racing and Mazda changed engines in their respective cars (the No. 48 Lamborghini and the No. 77 RT24-P), they were not demoted any grid places since the race lasted more than six hours.[51]

Race

Start

Weather conditions at the start of the race were dry but cloudy. The air temperature throughout was between 64 and 77 °F (18 and 25 °C) and the track temperature ranged from 62 to 80 °F (17 to 27 °C);[52] conditions were expected to remain consistent throughout the race, but a 70% chance of rain was forecast for Sunday.[31] Chip Ganassi Racing founder and owner Chip Ganassi waved the green flag at 14:40 Eastern Standard Time (UTC−05:00) to start the proceedings.[31][53] Fifty cars were due to take the start, but Robert Renauer spun on cold tyres and heavily damaged the left-hand quarter of the No. 58 Wright Motorsports car when he hit the turn five inside wall during the first formation lap.[54][55][56] Extensive repairs to the car were carried out for the next two hours and eight minutes.[57] Van Der Zande led from the start with Castroneves close behind. Nasr moved to third by the third lap and overtook Castroneves around the outside for second at turn seven. He lost third to Albuquerque two corners later. The first round of green flag pit stops for fuel began on lap 17, with Van der Zande stopping two laps later. He lost first to Albuquerque after all pit stops were carried out.[54] Hand took the GTLM lead from Magnussen in the opening minutes. Westbrook was also an early mover but fell to third after a slow pit stop to rectify brake issues. Jeffrey Schmidt's No. 29 Land Motorsport car moved to the front of GTD by passing Serra and having a faster pit stop than Molina who overtook Serra.[58]

Early in the second hour, problems during the second pit stop phase affected several cars. The right-front wheel on Bomarito's No. 55 Mazda detached and rested on the Armco barriers lining the circuit. Bomarito slowed to 45 mph (72 km/h) on his way to the pit lane, putting him three laps behind the overall leader; Tincknell relieved him at his pit box. Oliver Jarvis' sister No. 77 car was then transported into its garage for a downshifting problem that put him behind the GTLM leaders and five laps behind the overall pace setters.[59][60][56] Santiago Creel relieved Molina in the No. 82 Risi Ferrari, but a flash fire affected the car when fuel ignited at its pit stop after the nozzle was disconnected. The entry dropped 24 laps as it was tended to.[59][56] Ricky Taylor's No. 7 Penske car was delayed by its left-hand door loosening due to a broken latch; he remained on the same lap as the overall leader.[56] During this period, Vautier, Alonso and Barbosa all led outright.[59][60] Extreme Speed Motorsports gained the most positions: the No. 22 car of Derani had gained 15 places from starting 18th, while Olivier Pla's sister No. 22 entry overcame an earlier cut tire that necessitated an unscheduled pit stop to run in seventh.[61]

Derani was gaining on Barbosa when the first full course caution period of the race was activated for 14 minutes. James French in the No. 38 Performance Tech Oreca had stopped on the oval banking at turn seven halfway through the third hour because of no fuel.[56][62] Barbosa kept first from Derani at the restart. Two Jackie Chan cars separated the pair allowing Barbosa to draw clear and re-establish his advantage upfront, which grew to seven seconds.[63][64] Derani fell out of contention in the battle for the lead soon after his right-rear tire burst, shredding the right-rear quarter of his car and sending him to pit road for repairs. Matt McMurry in the No. 90 Spirit of Race car was demoted to third when Hunter-Reay's No. 10 Wayne Taylor entry, Simon Pagenaud's No. 6 Penske, and Middleton's No. 31 Whelen Engineering car got past him the lap after the restart. Middleton came into contact with Pagenaud at turn five; in spite of both remaining on the lead lap, Middleton earned a drive-through penalty. As night fell, James Calado's No. 62 Risi car, and Nunez' No. 77 Mazda, picked up punctures at the rear of their cars within 28 minutes of each other.[62][63]

Night

Before the fourth hour's end, Jordan Taylor's right-rear tire burst on the banking entering turn 12. Damage was minimal since he was near the pit lane and repairs took 29 seconds.[62][65] Light rain began falling just as the fifth hour began and several cars in all categories were caught out by the change of conditions.[66] Soon after, the rain intensified enough for most of the field to make pit stops for rain tyres. Marcel Fässler stayed on the circuit but was ten seconds slower than teammate Magnussen and was overtaken by Bourdais and Scott Dixon's Fords. The rain later tapered off, but the disparity of drying of the banking and the infield sections was problematic for rain tyre equipped cars. The first major incident in GTLM came 4 hours and 42 minutes in when Bill Auberlen's No. 25 BMW M8's right-front tyre was cut 10 mm (1.0 cm) from debris on the banking leaving turn six. He stayed off the wall and returned to his garage to repair front-right bodywork damage. Pilet remained on dry tyres and took the GTLM lead but dropped to fourth by the end of hour six. In the meantime, Fittipaldi lost the overall lead to Castroneves before Conway took it after he made a pit stop two laps later than both drivers.[62][67][68]

Norris was the best-placed LMP2 car and was sometimes the fastest overall and gained positions through superior fuel economy before Hanson took over the No. 23 vehicle.[69] Despite a front nose change at his pit stop, Castroneves retook the lead after Curran took over from Conway when the No. 5 car stopped. Castroneves was soon being gained on by Albuquerque who relieved Fittipaldi. The two drew level when Albuquerque used his car's extra torque to get a better exit out of the turn three hairpin. Albuquerque overtook Castroneves because the latter elected not to risk driving beside him entering the kink. Albuquerque opened up a five-second gap before handing the lead back to Castroneves ten minutes before the eighth hour ended on pit stop rotation.[69] Don Yount lost control of the No. 96 Turner BMW M6's rear at the Bus Stop chicane and hit the tyre wall heavily. No caution was needed.[70] Soon after, Hanson's right-rear tyre blew turning into the Bus Stop chicane, significantly damaging his car's bodywork. Hanson required an engine cover and rear wing replacement and Alonso took over from him. Castroneves again lost the lead to Albuquerque when he overshot his pit box and was half a minute adrift into hour nine. Third-placed Van der Zande picked up another right-rear puncture on the No. 10 Wayne Taylor car at the Bus Stop chicane; the carcass delaminated and deranged its bodywork and radiator line, forcing it into the garage for repairs. It dropped ten laps to the overall leader.[62][70]

McMurry brought the No. 90 Spirit of Racing car into his garage with a misfiring engine and later retired. Nick Tandy got past Antonio García's No. 3 Corvette but clipped the curb at the Bus Stop chicane too hard and speared into the tyre barrier after losing control of his vehicle's rear leaving the turn. He returned to the pit lane with heavy car damage. As it turned January 28, Nasr's right-rear tire failed but had minimal car damage and went to the pit lane for a replacement wheel.[62][70] The lead of GTD went to Adam Christodoulou's No. 33 Riley Mercedes-AMG because IMSA deemed that Jeffrey Schmidt's No. 29 Land Audi had exceeded the maximum rate of permitted fuel flow (a balance of performance transgression) at the car's pit stops. IMSA ordered the team to serve a five-minute stop-and-hold penalty.[71] The race's second full course yellow was activated for 18 minutes when Roberto González was on his out-lap on cold tyres and went straight into the tyre barrier at the third corner.[62][70][71] Mustang Sampling Racing changed the brake discs on the No. 5 car during the caution, allowing Ricky Taylor and Pagenaud into first and second overall.[70][71]

In GTD, Katherine Legge took over the class lead in the No. 86 Michael Shank Acura NSX when the No. 33 Riley Mercedes-AMG served a stop-and-hold penalty for speeding in the pit lane. Legge lost it soon after to Perera's No. 48 Paul Miller Racing Lamborghini and Brekers took second place in the class for Grasser. Meanwhile, the top four overall cars were separated by six seconds and three cars were contesting the battle for second place.[70] Barbosa sidedrafted Pagenaud with fourth-placed Nasr slipstreaming both cars on the approach to the Bus Stop chicane. Nasr out-braked both vehicles and passed them for second overall. Graham Rahal was now in the No.7 Penske Acura but was overtaken by Barbosa and Nasr. Ten hours and 30 minutes in, Alonso drove No. 23 United Autosports car into the garage with a master brake cylinder failure and fell out of contention for a top ten finish. One second separated the trio of Barbosa, Nasr and Rahal with Pagenaud drawing slightly closer in fourth. Nasr lost second to Rahal in the 11th hour. Pagenaud took the lead for a short time during the pit stop rotation for fuel. Rahal extended his advantage upfront as Barbosa and Nasr lost time on cold tyres, but Pagenaud gained first when Rahal spun and stalled at turn one.[62][70][72]

Morning

Mike Conway (pictured in 2016) of Whelen Engineering Racing was called to pit road for cooling issues in the 18th hour.

Conway regained first place through the next pit stop cycle. Tung slid the No. 78 Jackie Chan Oreca at the Bus Stop chicane and rear-ended the inside tire barrier. He made a pit stop for a replacement rear wing assembly and repairs to the car's front-left bodywork. The two Nissan DPis of Extreme Speed Motorsports driven by Ryan Dalziel and Derani retired by hour 14 because of respective terminal gearbox and engine failures.[62] Cameron led for three laps before his mechanics called him to pit road to inspect the No. 6 Penske car thoroughly for a suspected alternator problem that drained its battery. Cameron lost 25 laps to the leaders, and just three entries in the Prototype category were now on the lead lap.[62][73] Curran led at the beginning of the 15th hour but lost it to teammate Albuquerque when his rear brake light failed to work. A rear wing replacement was mandated at his unscheduled pit stop as he fell off the lead lap.[74] In the 16th hour's opening minutes, the third full course yellow flags were waved for 20 minutes. Jörg Bergmeister in the No. 73 Park Place Porsche had lightly hit the tire wall alongside the circuit and continued to the pit lane. Several cars in GTD took the opportunity to change brake discs during the caution.[62][75][76]

14 minutes after racing resumed, Castroneves and Nasr made contact, resulting in significant damage to the No. 7 Penske's left-hand side intercooler, radiator and bodywork, necessitating its return to the garage. It returned 25 laps adrift of the leader and out of contention for the overall win.[62][75] Van der Zande's No. 10 Wayne Taylor Cadillac sustained another right-rear puncture, this time at high speed. Team owner Wayne Taylor retired the car for driver safety reasons, uncertain of the cause of the problem, and he wanted to stop using spare bodywork parts.[62][77] Soon after, Bomarito's No. 55 Mazda retired at the West Horseshoe due to an exhaust problem that led the car to catch fire.[78] The fourth (and final) full course yellow was activated for 22 minutes when Kyle Masson put Legge off the track; he ploughed through an advertising billboard and Styrofoam blocks, littering debris on the circuit. Legge narrowly avoided impacting Masson's side. Under caution, Fittipaldi brought the No. 5 vehicle onto pit road to rectify an overnight cooling issue by removing the engine cover and adding water. This allowed Conway back on the lead lap.[62][79]

Conway stayed close by Fittipaldi as Braun got the No. 54 CORE car past the latter to regain one of its laps. Conway could not pass his teammate to regain first overall. Midway through the 19th hour, Conway was called to pit road for a similar cooling issue that hindered the sister No. 5 car; he kept second because Paul di Resta's No. 32 United Autosports car had a clutch pressure problem that temporarily prevented him from leaving pit road. He lost three laps to Fittipaldi.[62][80] The No. 11 Grasser Lamborghini took the lead in GTD after trading the position with the No. 33 Riley Mercedes-AMG for the past few hours. Meanwhile, teams scheduled their final pit stops and prepared their fastest drivers for their last stints. The leaders of two of the three categories were close by each other without over risking.[62] Overheating concerns slowed Nasr and fell to third behind Loïc Duval's No. 54 CORE car. Nasr retook second when Duval made a scheduled pit stop by the end of hour 22.[81]

Finish

Unhindered after relieving Fittipaldi in the final two hours, Albuquerque took the chequered flag for Mustang Sampling Racing in a record-breaking distance of 808 laps and 2,876.48 miles (4,629.25 km). This surpassed the previous record held by John Paul Jr., John Paul Sr. and Rolf Stommelen in a Porsche 935 at the 1982 race.[82] It was Barbosa and Fittipaldi's third outright victory at Daytona and Albquqerue's first.[82] Middleton's No. 31 Whelen Engineering car followed 1 minute and 10.544 seconds later in second, and Braun in the No. 54 CORE Oreca was the highest-placed LMP2 vehicle in third.[83][84] In GTLM, the No. 67 Ford of Briscoe, Dixon and Westbrook passed the sister No. 66 Ford of Hand, Dirk Müller and Bourdais in its final pit stop. It crossed the start-finish line after 783 laps to clinch Chip Ganassi Racing's 200th motor racing victory, and the team's second consecutive win, by 11.180 seconds after leading all but nine laps.[82] Dixon had his third victory at Daytona, Briscoe's was his second, and it was Hand's first.[85] The No. 3 Corvette of Garcia, Magnussen and Mike Rockenfeller completed the class podium in third.[82][84] Bleekemolen's No. 33 Riley Mercedes-AMG closed to within a second of Bortolotti's No. 11 GRT Lamborghini in the final half hour. A pit stop for fuel for Bleekemolen with 15 minutes left allowed Bortolotti to claim victory in GTD and Lamborghini's maiden 24 hour race win.[86] Parente got the No. 86 Michael Shank Acura NSX to second and Paul Miller's No. 23 Lamborghini took third with Andrea Caldarelli driving its final stint.[82]

Post-race

Continental Tire, one of the WeatherTech SportsCar Championship's two tire suppliers, suggested the increased competition in the Prototype category, teams double stinting their tires (the same sets brought by the company to Daytona for the past five years), and running them outside of their recommended air pressures and camber settings, were factors in several cars sustaining right-rear punctures during practice and the race.[87][88] Warm track temperatures, the highest in five years, led teams to lower tire air pressures to stop them from over-inflating once they reached their optimum running temperatures.[88] Furthermore, according to Continental Tire, they cautioned three teams over not receiving more sets of tires because they had not brought their limits in line with the company's recommendations. One team reported to Continental Tire that their tyre failures occurred after increasing their tyre pressures to the company's prescribed limits.[89] Regardless, at the 12 Hours of Sebring, Continental Tire debuted a more durable slick tyre which allowed for more aggressive setups and enhanced the likelihood that incidents such as the multiple punctures seen at Daytona would not reoccur in the future.[88][89]

The No. 29 Land Audi was impounded at technical inspection for three hours after the race. The team's refuelling equipment was deemed to comply with IMSA regulations, but a discrepancy in the fuel data provided to the series and the team was discovered.[90] Starting at Sebring, IMSA established minimum refuelling times for all classes, overriding all refuelling restrictor starting sizes issued to teams. This was listed in the category-wide balance of performance tables to counter the controversy.[91] Jarvis expressed his surprise that the race had just four caution periods compared to 21 in 2017, "We always talk about Daytona as [being about] staying out of trouble, staying on the lead lap – and if you do have a problem, don't worry, because you get laps back. But it just hasn't happened. I've never seen a Daytona 24 with such big gaps [between the leading cars]. It's a shame really because in the prototype class there hasn't been much of a race on, it's just survival to the finish."[92] Duval said the low number of cautions lessened his team's chances of the overall victory, because the day before it began they anticipated more than 20, "We tried to put some pressure on the guys [ahead] but it was a bit too late, they were a bit too far ahead."[92]

Since it was the first race of the season, Albuquerue, Barbosa and Fittipaldi led the Prototype Drivers' Championship with 35 points each. Conway, Curran, Middleton and Nasr were in second with 32 points. Bennett, Braun, Dumas and Duval were third with 30 points. Westbrook, Dixon and Briscoe took the GTLM points standings lead with their teammates Bourdais, Hand and Müller placing second. Garcia, Magnussen and Rockenfeller rounded out the top three. Bortolotti, Perera, Rik Breukers and Inechen led the GTD Drivers' Championship, followed by the second-placed Allmendinger, Parente, Legge and Hindman. Caldarelli, Sellers, Miller and Snow were third.[93] Mustang Sampling Racing, Chip Ganassi Racing and GRT Grasser Racing Team became the leaders of their respective class Teams' Championships. Cadillac, Ford and Lamborghini assumed the lead of their respective Manufacturers' Championships with 11 races left in the season.[93]
