72-403: The following table gives an overview on the titles in the series: Damage is realistically modeled, but can be turned off to make the player's car indestructible. The effect of crashes varies depending on severity. Very minor impacts have no effect. Heavier impacts can cause sheet metal damage, which hurts aerodynamics and may cause engine overheating. A crumpled hood can also make it difficult for

144-522: 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

216-543: A Ferrari 458 of the GTD category that has never won a race in North American Endurance . At the time of the impact, Malucelli was driving at less than 30 mph and keeping on the track while cars were passing him at 150 mph. Memo, who was side by side to another car couldn't have seen him and impacted front first. The race was subsequently red-flagged. Both drivers survived. The regular teams were expanded to three drivers in

288-403: A competitive race for players of varying skill levels. The game contains many real-life drivers. The game is the first stock car racing simulator to include real sponsors on their respective cars. Alcohol and tobacco sponsors were removed, but alternate car sets from fans restored many of these. NASCAR Racing also gives players the ability to set up their car in a realistic manner by adjusting

360-623: 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 the original ideas of IMSA and focused 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 (DP) use less expensive materials and technologies and

432-568: A custom engine and bodywork from a major manufacturer. For 2023, the race adopted the LMDh prototype specification, although Le Mans Hypercars were also permitted. The series has also returned to the Grand Touring Prototype name from the 1980's. 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

504-400: A gear train has two gears. The input gear (also known as the drive gear or driver ) transmits power to the output gear (also known as the driven gear ). The input gear will typically be connected to a power source, such as a motor or engine. In such an example, the output of torque and rotational speed from the output (driven) gear depend on the ratio of the dimensions of the two gears or

576-479: A lower frequency as they pass. A separate program called the Paintkit was included with NASCAR Racing , which allowed users to design their own race cars and import them into the game. As well as this, players could change the car type ( Chevrolet Lumina , Ford Thunderbird or Pontiac Grand Prix ) and the brand of tires used ( Goodyear or Hoosier ). Former racer-turned-broadcaster, Ned Jarrett loaned his voice to

648-407: A non-motorsport related occupation. These type of drivers are typically eligible for IMSA's Jim Trueman and Bob Akin awards, awarded to the top driver who is not a professional at the end of season. These amateur drivers or overage professional drivers (FIA Silver or Bronze are typically for amateur drivers but professional drivers over 55 are automatically classified at this level) are required in

720-464: A pitch circle radius of 2 in (51 mm), the angular speed ratio R A B {\displaystyle R_{AB}} is 2, which is sometimes written as 2:1. Gear A turns at twice the speed of gear B . For every complete revolution of gear A (360°), gear B makes half a revolution (180°). In addition, consider that in order to mesh smoothly and turn without slipping, these two gears A and B must have compatible teeth. Given

792-442: A very fast course. 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

864-451: Is a machine element of a mechanical system formed by mounting two or more gears on a frame such that the teeth of the gears engage. Gear teeth are designed to ensure the pitch circles of engaging gears roll on each other without slipping, providing a smooth transmission of rotation from one gear to the next. Features of gears and gear trains include: The transmission of rotation between contacting toothed wheels can be traced back to

936-407: Is called an idler gear. Sometimes, a single idler gear is used to reverse the direction, in which case it may be referred to as a reverse idler . For instance, the typical automobile manual transmission engages reverse gear by means of inserting a reverse idler between two gears. Idler gears can also transmit rotation among distant shafts in situations where it would be impractical to simply make

1008-476: Is equal to twice the thickness of a tooth, In the United States, the diametral pitch P {\displaystyle P} is the number of teeth on a gear divided by the pitch diameter; for SI countries, the module m {\displaystyle m} is the reciprocal of this value. For any gear, the relationship between the number of teeth, diametral pitch or module, and pitch diameter

1080-440: Is equivalently determined by the ratio of the number of teeth: In other words, the [angular] speed ratio is inversely proportional to the radius of the pitch circle and the number of teeth of gear A , and directly proportional to the same values for gear B . The gear ratio also determines the transmitted torque. The torque ratio T R A B {\displaystyle {\mathrm {TR} }_{AB}} of

1152-405: Is given by This shows that if the output gear B has more teeth than the input gear A , then the gear train amplifies the input torque. In this case, the gear train is called a speed reducer and since the output gear must have more teeth than the input gear, the speed reducer amplifies the input torque. When the input gear rotates faster than the output gear, then the gear train amplifies

1224-495: Is given by: Since the pitch diameter is related to circular pitch as this means Rearranging, we obtain a relationship between diametral pitch and circular pitch: For a pair of meshing gears, the angular speed ratio , also known as the gear ratio , can be computed from the ratio of the pitch radii or the ratio of the number of teeth on each gear. Define the angular speed ratio R A B {\displaystyle R_{AB}} of two meshed gears A and B as

1296-425: Is not connected directly to either the motor or the output shaft and only transmits power between the input and output gears. There is a third gear (Gear B ) partially shown in the upper-right corner of the photo. Assuming that gear is connected to the machine's output shaft, it is the output or driven gear. Considering only gears A and I , the gear ratio between the idler and the input gear can be calculated as if

1368-622: Is run on the Sports Car Course layout , a 3.56-mile (5.73 km) combined road course that uses most of the tri-oval plus an infield road course. Held on the last weekend of January or first weekend of February as part of Speedweeks , it is the first major automobile race of the year in North America. The race is sanctioned by IMSA and is the first race of the season for the IMSA SportsCar Championship . The race has borne

1440-424: Is the diameter of a gear's pitch circle, measured through that gear's rotational centerline, and the pitch radius r {\displaystyle r} is the radius of the pitch circle. The distance between the rotational centerlines of two meshing gears is equal to the sum of their respective pitch radii. The circular pitch p {\displaystyle p} is the distance, measured along

1512-399: Is the gear ratio of the gear train, the input torque T A {\displaystyle T_{A}} applied to the input gear A and the output torque T B {\displaystyle T_{B}} on the output gear B are related by the same gear or speed ratio. The torque ratio of a gear train is also known as its mechanical advantage ; as demonstrated,

1584-673: The Antikythera mechanism of Greece and the south-pointing chariot of China. Illustrations by the Renaissance scientist Georgius Agricola show gear trains with cylindrical teeth. The implementation of the involute tooth yielded a standard gear design that provides a constant speed ratio. The pitch circle of a given gear is determined by the tangent point contact between two meshing gears; for example, two spur gears mesh together when their pitch circles are tangent, as illustrated. The pitch diameter d {\displaystyle d}

1656-743: 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 . The Audi R8 and the Ferrari 458 Italia debuted in the 50th anniversary of the race in 2012. From the era of the IMSA GTO and GTU until the 2015 rule changes, 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

1728-527: The 1969 24 Hours of Daytona. The winning car was the Penske Lola T70 -Chevrolet of Mark Donohue and Chuck Parsons . 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." 1970 saw the race with drivers strapped into their cars, and at the start, drove away. Since 1971, races begin with rolling starts. In 1972, because of an FIA rule,

1800-459: The 1970s. Nowadays, four drivers compete typically because of the longer night driving. In the professional-based DPi Prototype and ACO GTE classes, all four drivers are usually professionals. In the ACO LMP2 and SRO Group GT3-based classes, many of these additional drivers are known as "amateur drivers," under current FIA specifications. Amateur drivers are sportsman drivers that have built a career in

1872-485: The Fords, the Ferrari P series prototypes staged a 1–2–3 side-by-side parade finish at the banked finish line in 1967. The Ferrari 365 GTB/4 road car was given the unofficial name Ferrari Daytona in celebration of this victory. 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 tire failure in the banking, his teammate Rolf Stommelen supported

1944-690: The GTLM class, using LM GTE cars, similar to the WEC. In 2022 the GTLM class was replaced by GTD Pro, using the same cars as GTD. A single GTLM car, the Corvette C8.R, was also permitted to compete in the class with its performance adjusted to the GTD cars. The 2013 race was the first and only year for the GX class. Six cars started in the event. The class consisted of purpose built production Porsche Cayman S and Mazda 6 racecars. Mazda debuted their first diesel racecar there which

2016-415: The airdam height, rear spoiler angle, gear ratios , shocks, tire pressures, cambers and more. Driving physics are realistically modeled in the game. The adjustable variables have a significant effect on handling, and the tires themselves will grip differently depending on wear and temperature. Tires are modeled in much detail. The game keeps track of 3 temperatures for each tire, reflecting temperatures at

2088-437: The angular rotation of all the gears in the gear train are defined by the angle of the input gear. The input torque T A {\displaystyle T_{A}} acting on the input gear A is transformed by the gear train into the output torque T B {\displaystyle T_{B}} exerted by the output gear B . Let R A B {\displaystyle R_{AB}} be

2160-520: The basic organization 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 ." 1966 also saw Suzy Dietrich enter the 24 Hours event, driving a Sunbeam Alpine with Janet Guthrie and Donna Mae Mims . The trio finished 32nd and, along with another women's team in the race, became the first women's teams to finish an international-standard 24-hour race. After having lost in 1966 at Daytona, Sebring and Le Mans to

2232-408: 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. 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

2304-510: The car for a specific number of hours. Most often, the fourth driver in all classes is a Daytona-only professional driver of renown that most often has won a major professional championship, such as Scott Dixon , Jeff Gordon , Fernando Alonso , Shane van Gisbergen and Kyle Busch . Unlike the Le Mans event, the Daytona race is conducted entirely over a closed course within the speedway arena without

2376-429: 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 third place, with only Mitter being left out. Lola finished 1–2 in

2448-535: The car's simple aerodynamics reduce the development and testing costs. The DPs began racing in 2003 with six cars in the race. 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 Cadillac , Lexus , Ford , BMW , and Porsche . 2017 saw the introduction of the DPi prototypes. These cars were based on LMP2 chassis with

2520-404: The center, inner, and outer edges. Numerous variables can influence tire temperatures. For example, an underinflated tire will tend to heat more at the edges rather than the center. An incorrect camber setting can cause one edge to heat more than the other. Temperatures are also influenced by many other factors such as weight distribution, toe-in, driver behavior, and the cornering characteristics of

2592-502: 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. 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

2664-433: The distant gears larger to bring them together. Not only do larger gears occupy more space, the mass and rotational inertia ( moment of inertia ) of a gear is proportional to the square of its radius. Instead of idler gears, a toothed belt or chain can be used to transmit torque over distance. If a simple gear train has three gears, such that the input gear A meshes with an intermediate gear I which in turn meshes with

2736-419: The drive gear ( A ) must make 1.62 revolutions to turn the output gear ( I ) once. It also means that for every one revolution of the driver ( A ), the output gear ( I ) has made 13 ⁄ 21 = 1 ⁄ 1.62 , or 0.62, revolutions. The larger gear ( I ) turns slower. The third gear in the picture ( B ) has N B = 42 {\displaystyle N_{B}=42} teeth. Now consider

2808-403: The driver and driven gear. If the driver gear moves in the clockwise direction, then the driven gear also moves in the clockwise direction with the help of the idler gear. In the photo, assume the smallest gear (Gear A , in the lower right corner) is connected to the motor, which makes it the drive gear or input gear. The somewhat larger gear in the middle (Gear I ) is called an idler gear. It

2880-440: The game also provides a few prefabricated setups for each track. Vehicles cannot lift into the air. The graphics system always renders them with all 4 wheels on the ground, although the physics system may attribute wheels with varying amounts of downforce (potentially resulting in no traction). The Doppler effect is simulated. Vehicles approaching at high relative speed will emit a higher frequency engine sound, which will shift to

2952-413: The game's title sequence, saying, "I'm Ned Jarrett. From Papyrus, this is NASCAR Racing ". These were the only spoken words heard in the game as there was no in-race commentary or communication from the crew chief . Music for the game was provided by members of Skid Row , including bass player Rachel Bolan who also appeared in the game as a driver of a green-and-purple No. 00 car with the letters "RB" on

3024-403: The gear ratio and speed ratio of a gear train also give its mechanical advantage. The mechanical advantage M A {\displaystyle \mathrm {MA} } of a pair of meshing gears for which the input gear A has N A {\displaystyle N_{A}} teeth and the output gear B has N B {\displaystyle N_{B}} teeth

3096-412: The gear ratio for the subset consisting of gears I and B , with the idler gear I serving as the input and third gear B serving as the output. The gear ratio between the idler ( I ) and third gear ( B ) R I B {\displaystyle R_{IB}} is thus or 2:1. The final gear ratio of the compound system is 1.62×2≈3.23. For every 3.23 revolutions of the smallest gear A ,

3168-415: The gear ratios of the two subsets are multiplied: Notice that this gear ratio is exactly the same as for the case when the gears A and B engage directly. The intermediate gear provides spacing but does not affect the gear ratio. For this reason it is called an idler gear. The same gear ratio is obtained for a sequence of idler gears and hence an idler gear is used to provide the same direction to rotate

3240-424: The gear train is defined as the ratio of its output torque to its input torque. Using the principle of virtual work , the gear train's torque ratio is equal to the gear ratio, or speed ratio, of the gear train. Again, assume we have two gears A and B , with subscripts designating each gear and gear A serving as the input gear. For this analysis, consider a gear train that has one degree of freedom, which means

3312-524: The gear train. The speed ratio R A B {\displaystyle R_{AB}} of the gear train can be rearranged to give the magnitude of angular velocity of the output gear in terms of the input gear velocity. Rewriting in terms of a common angular velocity, The principle of virtual work states the input force on gear A and the output force on gear B using applied torques will sum to zero: This can be rearranged to: Since R A B {\displaystyle R_{AB}}

3384-458: The gears will come into contact with every tooth on the other gear before encountering the same tooth again. This results in less wear and longer life of the mechanical parts. A non-hunting gear set is one where the teeth counts are insufficiently prime. In this case, some particular gear teeth will come into contact with particular opposing gear teeth more times than others, resulting in more wear on some teeth than others. The simplest example of

3456-639: The hood. Several mods were made available through various websites, including updated NASCAR seasons and car shapes, the 24 Hours of Daytona cars (with three car shapes), classic NASCAR seasons, touring cars and more. Users created versions of Daytona International Speedway , Las Vegas Motor Speedway and Texas Motor Speedway – edited from versions produced by Papyrus for later NASCAR Racing releases such as NASCAR 3 – for use in NASCAR 2 . Numerous utilities were developed for NASCAR Racing too, including AI editors, season editors and track editors. NASCAR Racing

3528-437: The idler gear was the output gear. The input gear A in this two-gear subset has 13 teeth ( N A {\displaystyle N_{A}} ) and the idler gear I has 21 teeth ( N I {\displaystyle N_{I}} ). Therefore, the gear ratio for this subset R A I {\displaystyle R_{AI}} is This is approximately 1.62 or 1.62:1. At this ratio, it means

3600-468: The input torque. Conversely, if the output gear has fewer teeth than the input gear, then the gear train reduces the input torque; in other words, when the input gear rotates slower than the output gear, the gear train reduces the input torque. A hunting gear set is a set of gears where the gear teeth counts are relatively prime on each gear in an interfacing pair. Since the number of teeth on each gear have no common factors , then any tooth on one of

3672-585: The largest gear B turns one revolution, or for every one revolution of the smallest gear A , the largest gear B turns 0.31 (1/3.23) revolution, a total reduction of about 1:3.23 (Gear Reduction Ratio (GRR) = 1/Gear Ratio (GR)). 24 Hours of Daytona The 24 Hours of Daytona , also known as the Rolex 24 At Daytona for sponsorship reasons, is a 24-hour sports car endurance race held annually at Daytona International Speedway in Daytona Beach, Florida . It

3744-469: The names of several sponsors over the years. Since 1992, the Rolex Watch Company has been the title sponsor of the race, replacing Sunbank , which replaced Pepsi in 1984. Winning drivers of all classes receive a Rolex Daytona watch. The race is known as a leg of the informal Triple Crown of endurance racing along with the 24 Hours of Le Mans and 12 Hours of Sebring . Shortly after

3816-436: The number of teeth N {\displaystyle N} : The thickness t {\displaystyle t} of each tooth, measured through the pitch circle, is equal to the gap between neighboring teeth (also measured through the pitch circle) to ensure the teeth on adjacent gears, cut to the same tooth profile, can mesh without interference. This means the circular pitch p {\displaystyle p}

3888-485: 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. Starting in 2014 the GT Daytona class was restricted exclusively to Group GT3 cars. Alongside this came

3960-490: The output gear B , then the pitch circle of the intermediate gear rolls without slipping on both the pitch circles of the input and output gears. This yields the two relations The speed ratio of the overall gear train is obtained by multiplying these two equations for each pair ( A / I and I / B ) to obtain This is because the number of idler gear teeth N I {\displaystyle N_{I}} cancels out when

4032-442: The pitch circle, between one tooth and the corresponding point on an adjacent tooth. The number of teeth N {\displaystyle N} per gear is an integer determined by the pitch circle and circular pitch. The circular pitch p {\displaystyle p} of a gear can be defined as the circumference of the pitch circle using its pitch radius r {\displaystyle r} divided by

4104-418: The player to see the track. Heavy impacts will damage a wheel or even blow the engine. Damage can be repaired in the pit stop, except for blown engines which are not repairable. Damaged sheet metal is removed, making for an imperfect repair with impaired aerodynamics. The vehicle's sensitivity to crash impacts was increased in a patch to the game. In the readme file attached to this patch, Papyrus explained that

4176-416: The primary motivation for this change was multiplayer mode, where violent players had previously been able to achieve faster lap times by deliberately hitting walls. Repairs require a considerable amount of time (generally 1 minute or longer) to complete. This combined with the impaired performance means that damaged vehicles will not contend for a high finish, but can still race for points which accumulate in

4248-487: The race track. Tires in the game perform optimally at elevated temperatures, but if they heat excessively this effect is lost. The player can view current tire temperatures using an in-game keyboard command. Dedicated players can spend a great deal of time optimizing the car's setup to perform at its best on a particular race track. This testing process is normally performed using the game's Practice or Testing modes. The player's setup can be saved to disk for future recall, and

4320-598: The race was shortened to six hours, while the energy crisis led to the cancellation altogether in 1974. The Sports Car Club of America sanctioning was replaced by the International Motor Sports Association in 1975. In 1982 the race continued on as part of the IMSA GT Championship instead of WSC . In 2014 , the race saw a dramatic crash involving Memo Gidley who was driving the pole-sitter DP and Matteo Malucelli, an amateur driver in

4392-749: The ratio of the magnitude of their respective angular velocities: Here, subscripts are used to designate the gear, so gear A has a radius of r A {\displaystyle r_{A}} and angular velocity of ω A {\displaystyle \omega _{A}} with N A {\displaystyle N_{A}} teeth, which meshes with gear B which has corresponding values for radius r B {\displaystyle r_{B}} , angular velocity ω B {\displaystyle \omega _{B}} , and N B {\displaystyle N_{B}} teeth. When these two gears are meshed and turn without slipping,

SECTION 60

#1732858542140

4464-421: The ratio of the tooth counts. In a sequence of gears chained together, the ratio depends only on the number of teeth on the first and last gear. The intermediate gears, regardless of their size, do not alter the overall gear ratio of the chain. However, the addition of each intermediate gear reverses the direction of rotation of the final gear. An intermediate gear which does not drive a shaft to perform any work

4536-428: The same tooth and gap widths, they also must have the same circular pitch p {\displaystyle p} , which means This equation can be rearranged to show the ratio of the pitch circle radii of two meshing gears is equal to the ratio of their number of teeth: Since the angular speed ratio R A B {\displaystyle R_{AB}} depends on the ratio of pitch circle radii, it

4608-428: The season standings. This game uses a scoring system similar to what NASCAR was using at the time, where all finishing positions earn a varying number of points. The engine will fail if over-revved, and it can also fail from overheating (but such a scenario is rare). Yellow flags can also be turned off and players can run any race distances of their choosing. The speed of computer opponents is also adjustable, providing

4680-401: The speed ratio, then by definition Assuming the gears are rigid and there are no losses in the engagement of the gear teeth, then the principle of virtual work can be used to analyze the static equilibrium of the gear train. Because there is a single degree of freedom, the angle θ of the input gear completely determines the angle of the output gear and serves as the generalized coordinate of

4752-458: 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. After several ownership changes at IMSA which changed the direction the organization followed, it was decided by the 1990s that the Daytona event would align with the Grand-Am series,

4824-415: The track opened, on April 5, 1959, a six-hour/1000 kilometer USAC - FIA sports car race was held on the road course. Count Antonio Von Dory and Roberto Mieres won the race in a Porsche , shortened to 560.07 miles (901.35 km) due to darkness. The race used a 3.81-mile layout, running counter-clockwise. This event is not considered to be part of the lineage of the eventual 24-hour race. In 1962,

4896-417: 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. 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,

4968-462: The velocity v {\displaystyle v} of the tangent point where the two pitch circles come in contact is the same on both gears, and is given by: Rearranging, the ratio of angular velocity magnitudes is the inverse of the ratio of pitch circle radii: Therefore, the angular speed ratio can be determined from the respective pitch radii: For example, if gear A has a pitch circle radius of 1 in (25 mm) and gear B has

In the United States, NASCAR Racing (bundled with its Track Pack add-on) was the 24th best-selling computer game of 1998, with another 225,737 units sold. Its revenue for that year was estimated at $ 2.28 million. NASCAR Racing and its sequel shipped above 2 million copies globally by March 1998. Gear ratio A gear train or gear set

5112-410: Was the case in the initial 1962 Daytona Continental (then 3 hours), in which Dan Gurney 's Lotus 19 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

5184-459: Was the first time a diesel fuel racecar ever started at the Daytona 24. Throughout the race the Caymans were dominant, while all three Mazdas suffered premature engine failure and retired from the race. By a 9 lap lead, the #16 Napleton Porsche Cayman, driven by David Donohue , was the GX winner. Porsche has the most overall victories of any manufacturer with 23, scored by various models, including
