|The Sprint Cup Series
(often shortened to Sprint Cup
or the Cup Series
) is the top racing series of the National Association for Stock Car Auto Racing (NASCAR). It was formerly known as the Strictly Stock Series
(1949) and Grand National Series
(1950-1970). While leasing its naming rights to R. J. Reynolds Tobacco Company, it was known as the Winston Cup Series
(1971-2003). When a similar deal was made with Sprint Nextel Corporation, it became the NEXTEL Cup Series
(2004-2007).  It is sometimes erroneously referred to as simply, NASCAR.
The drivers' champion is determined by a point system where points are given according to finishing placement and laps led. The season is divided into two segments. After the first 26 races, the 12 highest ranked drivers are seeded based on their total number of wins and compete in the last 10 races with the difference in points greatly equalized. This is called the Chase for the Championship.  In 2008, Jimmie Johnson became the only driver besides Cale Yarborough to win 3 consecutive Sprint Cup championships. Johnson was awarded a $7 million check, and for the 3rd time, the Sprint Cup.
The series holds strong roots in the Southeastern United States with half of its 36-race season in the former Confederate States. However, it has grown to become one of the six most popular professional sports leagues of the United States. The Daytona 500, its most prestigious race, had a television audience in the U.S. of about 16 million viewers in 2009.  Previously, races have been held in Canada, and exhibition races were held in Japan and Australia.
Sprint Cup Series cars are unique in automobile racing. The engines are powerful enough to reach speeds over , but high weight makes for poor handling. Their bodies and chassis are strictly regulated to ensure parity, and electronics are generally spartan in nature.

Strictly Stock & Grand National
In 1949, NASCAR introduced the Strictly Stock division, after sanctioning Modified and Roadster division races in 1948. Eight races were run, on seven different dirt ovals
and the Daytona Beach
beach/street course. 
The first NASCAR "Strictly Stock" race ever was held at Charlotte Speedway
on June 19 1949
. The race was won by Jim Roper
after Glenn Dunnaway
was disqualified after the discovery of his altered rear springs. The first series champion was Red Byron
. The division was renamed to "Grand National" for the 1950 season, reflecting NASCAR's intent to make its part of the sport more professional and more prestigious. It would retain this name until 1971.
The 1949 Strictly Stock season is treated in NASCAR's record books as the first season of GN/Cup history. Martinsville Speedway
is the only track on the 1949 schedule that remains on the current schedule.
Rather than a fixed schedule of one race per weekend with most entrants appearing at every event, the Grand National schedule included over sixty events in some years, often with two or three on the same weekend, and occasionally with two races on the same day in different states.
In the early years, most GN races were held on dirt-surfaced short oval tracks
(from under a quarter-mile to over a half-mile lap length) or dirt fairgrounds ovals (usually a half-mile to a mile lap length). 198 of the first 221 Grand National races were on dirt tracks. Darlington Raceway
opened in 1950 and became the first completely paved track on the circuit over one mile long. In 1959, when Daytona International Speedway
was opened, the schedule still had more races on dirt racetracks than paved ones. Through the 1960s, as superspeedway
s were built and old dirt tracks were paved, the number of dirt races was reduced. 
The last Sprint Cup Series race on a dirt track was held on September 30
at the half-mile State Fairgrounds Speedway
in Raleigh, North Carolina
. It was won by Richard Petty
in a Plymouth
that had been sold by Petty Enterprises
to Don Robertson and rented back for the race.
From 1971 through 2003, NASCAR's premier series was called the Winston Cup Series. It was sponsored by R. J. Reynolds Tobacco Company
cigarette brand Winston
. In its later years, RJR's sponsorship became more controversial in the wake of U.S. legislation that sharply restricted avenues for tobacco advertising.
The changes that resulted from RJR's involvement, as well as the reduction of the schedule from 48 to 31 races a year, established 1971 as the beginning of NASCAR's "modern era". The season was made shorter, and the point system was modified several times in the next four years. Races on dirt tracks
were removed from the schedule, as were oval track races shorter than 250 miles (402.336 kilometers). NASCAR's founder, Bill France, Sr.
, turned over control of NASCAR to his oldest son, Bill France Jr.
. In August 1974, France Jr. asked series publicist Bob Latford to design a point system with equal points awarded for all races regardless of length or prize money. 
This system ensured that the top drivers had to run all the races to become series champion. It was used without change from 1975 until the Chase for the Championship was instituted for 2004.
Since 1982, the Daytona 500
has been the first non-exhibition
race of the year.
Sports aired partial or full live telecasts of Grand National races from Talladega, North Wilkesboro, Darlington, Charlotte, and Nashville in 1970. These events were less exciting than many GN races, and ABC abandoned live coverage. Races were instead broadcast, delayed and edited, on the ABC sports variety show "Wide World of Sports
In 1979, the Daytona 500
became the first stock car race that was nationally televised from flag to flag on CBS
. The leaders going into the last lap, Cale Yarborough
and Donnie Allison
, wrecked on the backstretch while dicing for the lead, allowing Richard Petty
to pass them both and win the race. Immediately, Yarborough, Allison, and Allison's brother Bobby
were engaged in a fistfight on national television. This underlined the drama and emotion of the sport and increased its broadcast marketability. Luckily for NASCAR, the race coincided with a major snowstorm along the United States' eastern seaboard, successfully introducing much of the captive audience to the sport.
Starting in 1981, an awards banquet has been held the first Friday evening in December, at New York City's Waldorf-Astoria
Hotel, initially in the Starlight Roof. In 1985, the ceremony was moved to the much larger Grand Ballroom, where it would be held until 2001. In 2001, the banquet portion was dropped in favor of a simpler awards ceremony. In 2002, the awards ceremony was moved to the Hammerstein Ballroom
at the Manhattan Center
. In 2003, the banquet format returned, as the ceremony moved back to the Waldorf's Grand Ballroom.
In 1985 Winston introduced a new award program called the Winston Million
. From 1985 to 1997, any driver who won three of the four most prestigious races in the series was given $
1 million. This prize was only won twice during it's existence. Bill Elliott
won in 1985 and Jeff Gordon
won in 1997. 
It was replaced with a similar program, the Winston No Bull 5, in 1998 which awarded $1 million to any driver that won a prestigious race after finishing in the top-5 of the most previous prestigious race. 
The series underwent a large boom in popularity in the 1990s. 
In 1994, the NASCAR held the first Brickyard 400
at Indianapolis Motor Speedway
. Between 1997 and 1998, the winner's prize money for the Daytona 500 tripled. This coincided with a decline of popularity in American Championship Car Racing
In 1999, NASCAR agreed to a new broadcasting agreement with Fox Broadcasting
, Turner Broadcasting
. This particular television contract, signed for eight years for Fox and six years for NBC and Turner, was valued at $2.4 billion. 
NEXTEL & Sprint Cup
In 2003, RJR dropped its sponsorship of the top series, and NASCAR obtained a sponsorship from NEXTEL
, a telecommunications company. In 2004, the series became known as the NEXTEL Cup Series.
The 2005 merger between Sprint and NEXTEL resulted in the cup series being renamed the Sprint Cup
, beginning with the 2008 season.
The Sprint Cup trophy
is designed by Tiffany & Co.
, and is silver with a pair of checkered flags in flight. 
In 2009 it has become clear that the popularity boom of the 1990s is over. Television ratings have been more or less stagnant. Long time fans feel the series had lost its traditional appeal by abandoning tracks in the Southeastern United States
in favor of new markets. There is discontent over Toyota
's presence in the series. 
, Brian France
, has become a prime target for criticism among fans. 
Chase for the Championship
.When NEXTEL took over NASCAR's premier sponsorship for the 2004 season, the formula for declaring a series champion was rewritten using the USAR Hooters Pro Cup Series
as a model to develop major changes in scoring. 
After the first 26 races, a cut is made, with the twelve highest drivers and teams (plus ties) placed in the Chase for the Championship
(or simply "The Chase"). The Chase participants have their points increased to a level mathematically unattainable by anyone outside this field (roughly 1800 points ahead of the first driver outside of the Chase). Each driver who makes the Chase will receive 5,000 points, plus 10 additional points for each race he won during the first 26 races. Race layouts remain the same and points are scored the same way in the final 10 races. Whoever leads in points after the 36th race is declared the Sprint Cup champion.
To encourage continued competition among all drivers, a number of awards are given to drivers finishing outside the Chase. The highest finishing non-Chase driver (in 2007, 13th place at the end of the season) is awarded a bonus (approximately $
1 million) and a position on stage at the postseason awards banquet. The awards banquet now focuses solely on the Chase with all of the series' sponsored and contingency awards were moved to a luncheon at Cipriani the day before the banquet.
This playoff system was implemented primarily to make the points race more competitive late in the season, and indirectly, to increase television ratings during the NFL
season, which starts around the same time as the Chase begins. Furthermore, the Chase also forces teams to perform at their best during all three stages of the season—the first half of the regular season, the second half of the regular season, and the Chase. 
Previously, the champion may have been decided before the last race (or even several races before the end of the season) because it was mathematically impossible for any other driver to gain enough points to overtake the leader.
From 2004-2006 the Chase was shown in the United States on NBC
. In 2007, ESPN on ABC
telecast all ten races of the Chase as part of the new NASCAR television contracts that came in effect.

Sprint Cup Owner's Championship
The Sprint Cup Owner's Championship operates in the same manner as the Driver's Championship, but awarding points to each individual car (even if an owner enters more than one car, they are viewed and scored as separate entities). The points awarded are identical to the drivers' list, but with one addition - in the event of more than 43 cars attempting to qualify for a race, owner's points are awarded to each car in the following manner: the fastest non-qualifier (in essence, 44th position) receives 31 points, three less than the 43rd position car. If there is more than one non-qualifying car, owners' points continue to be assigned in the manner described, decreasing by three for each position.
There is a separate "chase for the championship" for the owners' points.
A 2005 rule change in NASCAR's three national series affects how the owner's points are used. The top 35 (Sprint Cup), or top 30 (other series) full-time teams in owner points are awarded exemptions for the next race, guaranteeing them a position in the next race. These points can decide who is in and out the next race, and have become crucial since the exemption rule was changed to its current format. At the end of each season, the top 35 in owner's points are also locked into the first five races of the next season.
In some circumstances, a team's owners' points will differ from the corresponding driver's points. In 2005, after owner Jack Roush
fired Kurt Busch
during the next-to-last race weekend of the season, the #97 team finished in eighth place in owner's points, while Busch ended up tenth in driver's points. In 2002, when Sterling Marlin
was injured, the #40 team finished eighth in owner's points, while Marlin was 18th in driver's points, because of substitute drivers Jamie McMurray
and Mike Bliss
, who kept earning owner points for the #40.

NASCAR does have a Manufacturer's Championship in their national series, although the Driver's Championship is considered more prestigious. In the past, manufacturer's championships were very prestigious because of the number of manufacturers involved, and the manufacturer's championship was a major marketing tool. In the Nationwide Series, the championship is known as the Bill France Performance Cup.
Points are scored in a 1960-1990 Formula One system, with the winner's manufacturer scoring nine points, six for the next manufacturer, four for the manufacturer third among makes, three for the fourth, two for the fifth, and one point for the sixth positioned manufacturer. This means that if Chevrolets place first through tenth in a given race and a Ford is 11th and a Dodge 12th, Chevrolet earns 9 points, Ford 6 and Dodge 4.

Sprint Cup cars
Sprint Cup Series cars (often called "Cup cars") adhere to a front engine rear-wheel-drive
design. A roll cage
serves as a space frame chassis
and is covered by a 24-gauge sheet metal
body. They have a closed cockpit, fenders, a rear wing, and an aerodynamic splitter. Fielding a car for one season usually costs $
10-20 million 
. Each team may build their own cars and engines (per NASCAR's specifications) or purchase cars and engines from other teams.
They are powered by carbureted
V8 engines, with cast iron blocks
, and a pushrod valvetrain
actuating two-valves per cylinder, and limited to 358 cubic inches (about 5.8 liters) displacement
. However, modern technology has allowed power outputs near in unrestricted form while retaining the conventional basic engine design. In fact, before NASCAR instituted the gear rule
, Cup engines were capable of operating in excess of 10,000 rpm. 
A Sprint Cup Engine with the maximum bore
of 4.185 inches (106.3 millimeters), and stroke
of 3.25 inches (82.55 millimeters) at 9,000 rpm has a mean piston speed
of 24.75 m/s (roughly that of a Formula One engine
The front suspension
is a double wishbone
design, while the rear suspension is a two-link live axle
design utilizing trailing arm
s. Brake rotor
s must be made of magnetic cast iron or steel and may not exceed 12.72 inches (32.3 centimeters) in diameter. 
The only aerodynamic components on the vehicles are the front splitter
, rear wing
(with endplates), NACA duct
s in the windows only, and side skirts. The use of rear diffusers
, vortex generator
s, wheel well vents, hood vents, and undertrays is strictly prohibited. While the cars may reach speeds of about 200mph (321.8 km/h) on certain tracks, Russ Wicks drove a stock car built to NASCAR's specifications 244.9mph (394.1 km/h) during a speed record attempt at the Bonneville Salt Flats
in October 2007. 
The electronic systems on Sprint Cup Cars remains rudimentary. Since the engines are carbureted
and the ignition system is mechanically timed
there is no need for an electronic control unit
. This prevents teams from using traction control
, anti-lock brakes
. During free test sessions, NASCAR's regulations involving electronics are relaxed allowing teams to utilize technologies such as telemetry, oxygen sensor
s, pitot tube
s, throttle position sensor
s, and many other devices to measure vehicle performance.
Evolution of Sprint Cup cars
driven by Dick Linder
in the 1951 Daytona Beach Road Course
When the series was formed under the name, strictly stock
, the cars were just that, production vehicles with no modifications allowed. The term stock car
implied that the vehicles racing were unmodified street cars. Drivers would race with factory installed bench seat
s and AM radio
s still in the cars. To prevent broken glass from getting on the race track, windows would be rolled down, external lights
would be removed or taped over, and wing mirror
s would be removed. Before the mid-1960s, cars were typically based on full sized cars such as the Chevrolet Impala
and Ford Galaxie
. Beginning in 1966, mid-size car
s including the Ford Fairlane
and Plymouth Belvedere
were adopted and soon became the norm.
's Plymouth Superbird
NASCAR once enforced a homologation
rule that at various times stated as few as 500 cars had to be produced, or as many as one car for every make's dealership in the nation had to be sold to the general public to allow it to be raced. Eventually, cars were made expressly for NASCAR competition, including the Ford Torino Talladega
, which had a rounded nose, and the Dodge Charger Daytona
and Plymouth Superbird
which had a rear wing raised above roof level and a shark shaped nose-cap which enabled speeds of over . Beginning in 1970, NASCAR rewrote the rules to effectively outlaw such outlandish aerodynamic devices.
In 1971, NASCAR phased in a rule to lower the maximum engine displacement
from 429 cubic inches (7.0 liters) to its present 358 cubic inches (5.8 liters). NASCAR handicapped the larger engines with a restrictor plate
. The transition was not complete until 1974 and coincided with American manufactures ending factory support
of racing and the 1973 oil crisis
s at Richmond International Raceway
The downsizing of American cars in the late 1970s presented a challenge for NASCAR. Rules mandated a minimum wheelbase of 115 inches, but after 1979, none of the models approved for competition met the standard, as mid-sized cars now typically had wheelbases between 105 and 108 inches. After retaining the older models (1977 for the GM makes, and 1979 for Ford and Dodge) through 1980, for the 1981 season the wheelbase requirement was reduced to 110 inches, which the newer model cars could be stretched to meet without affecting their appearance. The Buick Regal with its swept-back "shovel" nose initially dominated competition, followed by the rounded, aerodynamic 1983 Ford Thunderbird
. The Chevrolet Monte Carlo
and Pontiac Grand Prix
adopted bubble back windows to stay competitive. Amid its financial woes, and after dropping its rear-drive coupes, Chrysler Corporation
left NASCAR entirely.
marked an unfortunate milestone for Sprint Cup cars. During the 22nd lap of the Winston 500
, driver Bobby Allison
had a tire fail in the middle of Talladega Superspeedway
. Allison’s car hit the catch fence and tore a hole in the fence approximately long. Several spectators were injured in the accident, including one woman who lost an eye. 
In the aftermath of the crash, NASCAR mandated the use of a restrictor plate at Talladega Superspeedway and Daytona International Speedway
to reduce speeds.
By 1989, GM had switched its mid-sized models to V6 engines and front-wheel-drive, but the NASCAR racers only kept the body shape, with the old V8 rear-wheel-drive running gear, rendering obsolete the "stock" nature of the cars. When the Ford Thunderbird
was retired, without Ford having any two-door intermediate bodies, the four-door Ford Taurus
body was used (although NASCAR racers actually have no opening doors).
While the manufacturers and models of automobiles used in racing were named for production cars (Dodge Charger R/T
, Chevrolet Impala SS
, Toyota Camry
, and the Ford Fusion
), the similarities between Sprint Cup cars and actual production cars were limited to a small amount of shaping and painting of the nose, headlight and tail light decal
s, and grill areas. Until 2003, the hood, roof, and decklid were still required to be identical to their stock counterparts.
's 2007 Ford Fusion
at Texas Motor Speedway
It was in this time that NASCAR engaged in the practice of mandating rule changes during the season if one particular car model became overly dominant. This often led to claims that some teams would attempt sandbagging
in order to receive more favorable handicaps.
Because of the notorious manner of the Ford Taurus
race car and how the manufacturer turned the car into an "offset" car (the car was notoriously asymmetrical
in race trim because of its oval shape), NASCAR ended this practice to put more emphasis on parity and based new body rules in 2003, similar to short track racing, where offset cars had become a burden for race officials, resulting in the "Approved Body Configuration" design.
Car of Tomorrow (2007-present)
In 2007, NASCAR introduced a radically new vehicle specification known as the "Car of Tomorrow" (CoT). Its debut was at Bristol Motor Speedway
in March. Initially, the CoT was only used at 16 selected events. 
While NASCAR originally planned to wait until the start of the 2009 season to use the CoT in every race, they changed that date to the start of the 2008 season. Many drivers still had complaints about the CoT, but this new timeline was intended to help teams save money by giving them only one car specification to work on.
The design of this car has focused on cost control, parity, and driver safety.
The car's width has been increased by 4 inches (10 centimeters), the bumpers have been re-designed render bump and run
tactics less effective, and the height of the car has increased by 2 inches (5 centimeters) to accommodate taller drivers and increase aerodynamic drag
. The driver's seat was moved closer to the center of the car. The most noticeable change to fans will be the addition of a rear wing replacing the familiar spoiler
. The wing may be adjusted between 0-16 degrees and are used with multiple configurations of end plates. NASCAR owns all wings distributes them randomly at each event.
New rules for the car eliminate the asymmetrical bodies on cars which had run rampant since the 1998 Taurus release. However, almost all advantages of using one car over another have been nullified. NASCAR requires all CoTs to conform to common body templates
, regardless of make and model.
The automobiles' suspension, brakes, and aerodynamic components are also selected to tailor the cars to different racetracks. A car that understeer
s is said to be "tight", or "pushing," causing the car to keep going up the track with the wheel turned all the way left, while one that oversteer
s is said to be "loose," or "free," causing the back end of the car to slide around which can result in the car spinning out if the driver is not careful. The adjustment of front and rear aerodynamic downforce
, spring rate
s, track bar
geometry, brake proportioning, the wedge (also known as cross-weight), changing the camber angle
, and changing the air pressure in the tires can change the distribution of forces among the tires during cornering to correct for handling problems. Recently, coil bind
setups have become popular among teams.
These characteristics are also affected by tire stagger (tires of different circumference at different positions on the car, the right rear having the most influence in left turns) as well as the rubber compounds used in tire construction. These settings are determined by NASCAR and Goodyear
engineers and may not be adjusted by individual teams.
Changing weather conditions may also effect a car’s handling. In a long race, it is sometimes advantageous to prepare a car to handle well at the end of an event while surrendering speed at the start. Without electronic controls, the carburetor
must be tuned manually for the expected air temperature and barometric pressure. Rain will force a race to be halted immediately as there is no current provision for rain tire
s. While rain tires were developed for the series in the late 1990’s, NASCAR abandoned them as there were not enough road course
s on the schedule to justify the cost making more tires to replace them as they aged. Sprint Cup cars have used these tires in practice sessions, but only the Nationwide Series
has used them in race conditions. There was, however, one case of a Sprint Cup race being held in the rain. In 1956 a race at Road America
was held in rain and won by Tim Flock

Richmond International Raceway
Michigan International Speedway
Daytona International Speedway
Phoenix International Raceway
Sprint Cup races are not conducted on identical tracks. As of 2009 there are 20 oval track
s and 2 road course
s on the schedule. Oval tracks vary in length from 0.526 miles (847 m) (Martinsville Speedway
) to 2.66 miles (4.28 km) (Talladega Superspeedway
). While some tracks are true ovals (Bristol Motor Speedway
, Dover International Speedway
), many are tri-ovals (Kansas Speedway
, Daytona International Speedway
). Other configurations are quad-oval (Lowe's Motor Speedway
, Atlanta Motor Speedway
, Texas Motor Speedway
), D-oval (California Speedway
, Michigan International Speedway
, Richmond International Raceway
), oval with unequal ends (Darlington Raceway
), triangular (Pocono Raceway
), and almost-rectangular (Indianapolis Motor Speedway
). Courses also differ in degree of banking on the curves, with differences in degree of banking and course length contributing to different top speeds on various courses. New Hampshire Motor Speedway
and Phoenix International Raceway
are considered "flat" tracks as they have only 7 and 11 (respectively) degrees of banking in the turns. Infineon Raceway
and Watkins Glen International
are complex shaped road courses. While the series has a reputation for being oval centric, there has always been at least one road course on the schedule since its inception.
Race speeds vary widely based on the track. The fastest track is Talladega Superspeedway where the record race average speed is 188 mph (303 km/h) with the record qualifying lap of 212.809 mph (342.483 km/h) set by Bill Elliott
in 1987. 
The slowest tracks are Infineon Raceway, a road course, with a record race average speed of only 81 mph (130 km/h) and qualifying lap of 99 mph (159 km/h); and Martinsville Speedway, a very short, nearly flat "paper clip" shaped oval, with a record race average speed of 82 mph (132 km/h) and a qualifying lap of only 98 mph (156 km/h). The average speed is figured out based upon the winner's race time throughout the entire race, from the waving of the green flag
to the waving of the checkered flag
, including laps spent under caution, divided by the distance of the race. Time during red flag
periods is not added into the calculation of the average speed.
