The 24 Hours of Daytona, currently known as the Rolex 24 Daytona for sponsorship reasons, is a 24-hour sports car endurance race held annually at Daytona International Speedway in Daytona Beach, Florida. It is run on a 3.56-mile (5.73 km) combined road course, utilizing portions of the NASCAR tri-oval and an infield road course. Since its inception, it has been held the last weekend of January or first weekend of February, part of Speedweeks, and it is the first major automobile race of the year in the United States.
The race has had several names over the years. Since 1991, the Rolex Watch Co. is the title sponsor of the race under a naming rights arrangement, replacing Sunbank (now SunTrust) which in turn replaced Pepsi in 1984. Winning drivers of all classes receive a steel Rolex Daytona watch.
In 2006, the race moved one week earlier into January to prevent a clash with the Super Bowl, which had in turn moved one week later into February a few years earlier.
The race has been known historically as a leg of the informal Triple Crown of endurance racing, although increasing isolation from international Sports Car racing regulations has seen a gradual shift of importance to Petit Le Mans.

In 1962, a few years after the track was built, a 3-hour sports car race was introduced. Known as the Daytona Continental, it counted towards the FIA's new International Championship for GT Manufacturers. The first Continental was won by Dan Gurney, driving a 2.7L Coventry Climax-powered Lotus 19. Gurney was a factory Porsche driver at the time, but the 1600-cc Porsche 718 was considered too small and slow for what amounted to a sprint race on a very fast course.
In 1964, the event was expanded to 2,000 km (1,240 mi), doubling the classic 1000 km distance of races at Nürburgring, Spa and Monza. The distance amounted to roughly half of the distance the 24 Hours of Le Mans winners covered at the time, and was similar in length to the 12 Hours of Sebring, which was also held in Florida in March. Starting in 1966, the Daytona race was extended to the same 24-hour length as Le Mans.
Unlike the Le Mans event, the Daytona race is conducted entirely over a closed course within the speedway arena without the use of any public streets. Most parts of the steep banking are included, interrupted with a chicane on the back straight and a sweeping, fast infield section which includes two hairpins. As unlike Le Mans, the race is held in wintertime, when nights are at their longest. There are lights installed around the circuit for night racing, although the infield section is still not as well-lit as the main oval. However, the stadium lights are turned on only to a level of 20%, similar to the stadium lighting setup at Le Mans, with brighter lights around the pit straight, and decent lighting similar to street lights around the circuit.
In the past, a car had to cross the finish line after 24 hours to be classified, which led to dramatic scenes where damaged cars waited in the pits or on the edge of the track close to the finish line for hours, then restarted their engines and crawled across the finish line one last time in order to finish after the 24 hours and be listed with a finishing distance, rather than dismissed with DNF (Did Not Finish). This was the case in the initial 1962 Daytona Continental (then 3 hours), in which Dan Gurney's Lotus had established a lengthy lead when the engine failed with just minutes remaining. Gurney stopped the car at the top of the banking, just short of the finish line. When the three hours had elapsed, Gurney simply cranked the steering wheel to the left (toward the bottom of the banking) and let gravity pull the car across the line, to not only salvage a finishing position, but actually win the race. This led to the international rule requiring a car to cross the line under its own power in order to be classified.
The first 24 Hour event in 1966 was won by Ken Miles and Lloyd Ruby driving a Ford Mk. II. Motor Sport reported: "For their first 24-hour race the basic organisation was good, but the various officials in many cases were out of touch, childish and lacked the professional touch which one now finds at Watkins Glen."[1] After having lost in 1966 both at Daytona and at Le Mans to the Fords, the Ferrari P series prototypes staged a 1–2–3 side-by-side parade finish at the banked finish line in 1967.[2] The Ferrari 365 GTB/4 road car was given the unofficial name Ferrari Daytona in celebration of this victory.[3]
Porsche repeated this show in their 1–2–3 win in the 1968 24 Hours. After the car of Gerhard Mitter had a big crash caused by tyre failure in the banking, his teammate Rolf Stommelen supported the car of Vic Elford and Jochen Neerpasch. When the car of the longtime leaders Jo Siffert and Hans Herrmann dropped to second due to a technical problem, these two also joined the new leaders while continuing with their car. So Porsche managed to put 5 of 8 drivers on the center of the podium, plus Jo Schlesser and Joe Buzzetta finishing in 3rd place, with only Mitter being left out.[4]
Lola finished 1-2 in the 1969 24 Hours of Daytona. The winning car was the Penske Lola T70-Chevrolet of Mark Donohue and Chuck Parsons.[5] Few spectators witnessed the achievement as Motor Sport reported: "The Daytona 24-Hour race draws a very small crowd, as can be seen from the empty stands in the background."[6]
In 1972, due to the energy crisis, the race was shortened to 6 hours, while for 1974 the race was cancelled altogether.
In 1982, following near-continuous inclusion on the World Sportscar Championship, the race was dropped as the series attempted to cut costs by both keeping teams in Europe and running shorter races. The race continued on as part of the IMSA GT Championship.
The regular teams were expanded to 3 drivers in the 1970s. Nowadays, often four or five drivers compete. The winning entry in 1997 featured as many as seven drivers taking a turn in the cockpit.
After ownership problems with IMSA in the 1990s, the Daytona event aligned with the Grand-Am series, a competitor of the American Le Mans Series, which, as its name implies, uses the same regulations as the Le Mans Series and the 24 Hours of Le Mans. The Grand Am series, though, is instead closely linked to NASCAR and its focus is on controlled costs and close competition.
In order to make sports car racing less expensive than elsewhere, new rules were introduced in 2002. The dedicated Daytona Prototypes use less expensive materials and technologies and the car's simple aerodynamics reduce the development and testing costs.
Specialist chassis makers like Riley, Dallara, and Lola provide the DP cars for the teams and the engines are branded under the names of major car companies like Pontiac, Lexus, Ford, BMW, and Porsche.
The Gran Turismo class cars at Daytona are closer to the road versions, similar to the GT3 class elsewhere. For example, the more standard Cup version of the Porsche 996 is used, instead of the usual RS/RSR racing versions. Recent Daytona entries also include BMW M3s and M6s, Porsche 911s, Chevy Camaros and Corvettes, Mazda RX-8s, Pontiac GTO.Rs, and Ferrari F430 Challenges
In an effort for teams to save money, GT rules have now changed to permit spaceframe cars clad in lookalike body panels to compete in GT (the new BMW M6, Chevrolet Camaro, and Mazda RX-8). These rules are similar to the old GTO specification, but with more restrictions.
The intent of spaceframe cars is to allow teams to save money, especially after crashes, where teams can rebuild the cars for the next race at a much lower cost, or even redevelop cars, instead of having to write off an entire car after a crash or at the end of a year.
Since the Rolex 24 has a winter date during the off-season for other racing series, many top class drivers are available to take part in the event if sponsorship commitments allow. The track's marketing has sold the roll call of champions, considering the race a sort of "all-star" event of motorsports figures. Since each entry requires 3–5 drivers to trade shifts throughout the 24 hours, dozens of one-off drivers are necessary, and top-level participants from other forms of racing are highly sought after.
NASCAR stars such as Rusty Wallace, Tony Stewart, Jeff Gordon, Jimmie Johnson, Greg Biffle, Kurt Busch, Kyle Petty, Mark Martin, and Robby Gordon have all participated, with Martin and Gordon notably winning several class victories for Roush Racing in the GTO class in the 1980s–90s. In 2001, Dale Earnhardt and Dale Earnhardt, Jr. teamed together in a Corvette, just weeks before Earnhardt's fatal crash at the same track in the 2001 Daytona 500.
Indianapolis 500 winners Buddy Rice, Dan Wheldon, Hélio Castroneves, Juan Pablo Montoya, Sam Hornish, Jr., and Dario Franchitti are all recent participants. Other recent IndyCar drivers such as Paul Tracy, Sébastien Bourdais, Danica Patrick, Jimmy Vasser, John Andretti, and Graham Rahal.
Porsche has the most overall victories of any manufacturer with 22, scored by various models, including the road based 911, 935 and 996. Porsche also won a record 11 consecutive races from 1977–1987 and won 18 out of 23 races from 1968–1991.
