races has been frequently debated. NASCAR has been challenged on the types and frequency of caution flags, with some critics suggesting the outcome of races is being manipulated, and that the intention is not safety, as NASCAR claims, but closer racing.

Reasons cited for its decline include the aforementioned track changes, the introduction of the

Changes in stock car style

Beginning in the early 2000s, NASCAR researched and worked on a new model to introduce towards the end of the decade. One particular area of scrutiny was driver safety;
Dale Earnhardt Ralph Dale Earnhardt Sr. (; April 29, 1951February 18, 2001) was an American professional stock car driver and team owner, who raced from 1975 to 2001 in the former NASCAR Winston Cup Series (now called the NASCAR Cup Series), most notably dri ...

, and the safety of the cars used at the time was questioned. The Car of Tomorrow (CoT) was first tested in December 2005, and was first revealed to the public in 2006, with numerous safety improvements being touted. The CoT made its debut at the 2007 Food City 500, and was almost immediately criticized by both fans and drivers alike. Many fans disliked the large and boxy design, its more generic appearance and the use of a detached wing.

Busch was not the only driver to vent his frustrations;

, and overall brought dramatic safety improvements and reduced costs of car maintenance. Despite the overall safety improvements, one point of contention was that the rear wing increased the severity of on-track accidents by causing cars to be more prone to flipping over or going airborne at higher speeds. After three such incidents between 2007 and 2010, NASCAR switched to a more traditional rear spoiler instead. In a retrospective interview in 2015, Brian France believed that the introduction of the model as his biggest failure, due to the lack of manufacturer identity, as well as its perceived effects on its racing. Even after the implementation of the Generation 6 model, some fans still cite the CoT for causing the decline of NASCAR. Writer Christopher Smith of Car Throttle wrote that, "...NASCAR rules pretty much require all the race cars to be the same - no individuality aside from stickers that differentiate the models. NASCAR television ratings and fan interest has been decreasing for years, and as far as I’m concerned, this is the main reason." The Generation 6 cars themselves, while somewhat better received than the CoT (Generation 5) cars were at the time, have received some blow-back.

NASCAR later faced criticism over the Generation 6 cars over the change to high

due to hearing loss caused by engine noise. According to the article, a NIOSH engineer suggested putting mufflers on the cars in order to reduce the noise, but a NASCAR spokesperson stated that they already tried that in the 1960s, and it did not work as intended.


Business structure and decision-making policies

Since its founding in 1947 by
William France Sr. William Henry Getty France (September 26, 1909 – June 7, 1992), also known as Bill France Sr. or Big Bill, was an American businessman and racing driver. He is best known for founding and managing NASCAR, a sanctioning body of US-based stock ca ...
, the overall NASCAR organization has been majority owned by the France family, ensuring that the family controls a majority of the revenue that the sport generates. NASCAR is also criticized for its reluctance to promote some aspects of safety that it would have to pay for (''e.g.'', traveling safety crew), and other allegedly monopolistic aspects such as merchandising and race-track ownership. In addition, due to its influence and lack of drivers' say, NASCAR has been described as a "benevolent dictatorship", with a top-heavy command structure that tends to keep dissenters in line. Examples of such influence included the cancellation of the

NASCAR has taken to penalizing drivers in recent years, with fines, point penalties, and lap penalties in races for drivers or mechanics who use obscene language in interviews to the media. Because of Fox Sports' heavy affiliation with NASCAR, a fair amount of the network's programming is NASCAR-related. The charter system, introduced in 2016 with the involvement of

, has also been criticized as increasing entry barrier for new teams to enter the Cup Series while favoring larger, established teams with multiple cars and allowing smaller ones possessing charters to stagnate on-track. Following the announcement that Leavine Family Racing was shutting down at the end of the 2020 season, team owner Bob Leavine claimed that the team did not get the most of the charter for what he paid for it.


Driver competition in multiple series

NASCAR has long allowed drivers to compete in as many series and events as they like, with few restrictions. However, in recent years, many Cup Series drivers have competed in and dominated the lower tier Xfinity Series races on a regular basis, earning Cup drivers the nickname " Buschwhackers" (derived from the 1984–2007 sponsorship of NASCAR's second-highest series by

). The situation is compounded by the close timing of the races in the two series: a typical NASCAR weekend has an Xfinity race on Saturday followed by a Cup race on Sunday at the same track. Some have wondered why "major league" Cup drivers are allowed to compete in the "minor league" races with such frequency, and whether Xfinity is an adequate developmental series. Sportswriter Bob Margolis noted that much of this is due to the similarities between the cars used in the two series (they are mostly alike except for the engines and the wheelbase), and the desire for Cup drivers to get as much practice time as possible to learn about the track and car setup before the main race. In the aforementioned 2008 meetings between NASCAR and Detroit automakers, the automakers also called for the Xfinity Series to become strictly a developmental series, with Cup drivers prohibited from running in the junior series. The request was rejected at that time. However, in late 2010, media reports began to indicate that NASCAR may institute a slightly modified version of this rule for 2011, with Cup drivers allowed to run in Xfinity races but not to compete for the series championship. In January 2011, ''NASCAR.com'' confirmed this, adding that drivers will now be allowed to compete for the championship in only one national series in a given season, a change that also affects the

. In October 2016, NASCAR announced new participation guidelines for its three national series, limiting the number of Xfinity Series and Truck Series races that full-time drivers in its premier series will be allowed to compete in, starting in 2017.


Environmental effects


Fuel consumption

According to NASCAR, about 6,000 U.S. gallons (~23,000 litres) of fuel are consumed during a typical Cup Series weekend. For the 2006 season, which included 36 points races, the total for the season would have been 216,000 U.S. gallons (818,000 000 litres). One environmental critic recently estimated NASCAR's total fuel consumption across all series at 2 million U.S. gallons (7,570 000 litres) of gas for one season. At race speeds, Cup Series cars get 2 to 5 miles per gallon. Consumption under caution can be estimated at 14-18 mpg, based on comparable engines generally available to the public. The ''rate'' of fuel consumption tends to be the same regardless of the actual speeds of the cars, as teams change gear ratios for each race to ensure that the engine always operates in its optimum power band; however, the fuel ''mileage'' will vary for each race, depending on the maximum speeds attained. The fuel consumption criticism dates to 1974 and the

Lead is a well-known environmental risk, but the performance needs of race engines (in particular, the high compression ratios and sustained/repeated operation at high rpm and load) once made it difficult to switch to un leaded fuel. In the United States, the commercial use of leaded fuel has been phased out since the early 1970s, when catalytic converters were required to be installed on new cars, making unleaded fuel a requirement (leaded fuel will destroy a

The engine failures of both Earnhardt and Truex were attributed in part to the lack of a lead additive, but also to centrifugal force causing improper distribution of oil between the left and right sides of the engine. Evernham Motorsports has not disclosed the reason behind Kahne's engine failure. The 2008 season marked the first season all 36 races used unleaded racing fuel. 2011 marked one of the largest "green initiatives" in the fifty plus year history of NASCAR when all fuel sources were to include Ethanol in a blend called E15. One unintended consequence of the conversion was higher horsepower and therefore slightly lower fuel economy. It is argued however, that the reduction in fuel economy and the resultant increase in fuel use may offset any environmental impact savings by reduced emissions. Although not connected to the fuel blend, a new "Dry Break" self-venting fuel supply can was also adopted in part for safety (reduced the number of people working on the racecar during a pit stop) but also in part to reduce the amount of fuel spilled during a pit stop, which has both environmental and safety implications. In 2012 a complete technology change and shift in thinking occurred when NASCAR switched the Monster Energy NASCAR Cup Series to

Criticism of tracks


Changes in traditional tracks

In 1965 90.9% of the NASCAR schedule was in the South Region of the US and it stayed above 70% until 1989. The Northeast Region started out with a high percentage of races in the early NASCAR years, but from the 1960s until the mid 1980s contained 10% or less of the schedule. The Midwest Region had 21.1% of the races in 1950, but many years before 1970 had no races. The NASCAR schedule had usually contained a few races in the West Region but never more than 10% until the late 1990s. From the late 1990s, and into the early 2000s, a number of new tracks were built and became part of the NASCAR schedule, in places such as

Today, the South makes up only 50% of the NASCAR schedule, while the Northeast has 19.4%, the Midwest has 16.7%, and the West has 13.9% of the schedule. A consequence of NASCAR maintaining its current 36-race schedule is that the inclusion of these new tracks in the schedule results in some of the more traditional tracks in the

), compared to the 12.9% (4 races) in 1996. Before NASCAR cut the number of races down for the 1972 season, tracks under 1 mile made up more than 55% of the races. After the changes for the 1972 season, tracks under 1 mile made up only 29% of the races in 1972 and then had 10 races, around 33% of the races, until the mid 1980s. After losing 2 races at Nashville in 1985 and 2 races at North Wilkesboro after 1996 the NASCAR schedule had only 17.6% of races under 1 mile. Tracks with a length between 0.5 and under 1 mile had the highest percentage of the schedule from NASCAR's first season in 1949 until the mid 1990s when tracks between 1.000 and 1.499 miles equaled them in percentage. Tracks between 1.000 and 1.499 miles had the most races in the late 1990s until 1.5–1.999-mile tracks passed them in the early to mid 2000s after the loss of races at Rockingham and Darlington. Today 1.5–1.999-mile tracks have over 30% of the races. The counterargument is that these "traditional" venues are in markets whose support for racing had long declined – Darlington failed to sell out races until it was cut to one date in 2005 while North Wilkesboro had no infrastructure and little ability to expand beyond 50,000 seats, and Rockingham failed to sell out its races for over five years. The 2008 NASCAR–Detroit meetings also saw two automakers call for the addition of at least two new road races. One of these manufacturers also favored reducing the total number of races by at least four while at the same time increasing the number of road races from its current two to at least four. The most obvious way to achieve these goals would be to reduce the number of tracks that host two events a year. These demands were rejected.


Decline of road courses (1970s to 2020)

Since the seventies, NASCAR has increasingly focused its emphasis on oval courses. Such a plan was questioned as a key detriment to NASCAR, generating the stereotype of drivers and the sport as "a bunch of hillbillies driving in circles for three hours." Previously, some races were held on road courses, but by 1990 only two road courses were in use:
Sonoma Raceway Sonoma Raceway (originally known as Sears Point Raceway from 1967 to 1980 and 1982 to 2002, Golden State International Raceway in 1981 and Infineon Raceway from 2002 to 2012) is a road course and dragstrip located at Sears Point in the southe ...

Also notable is the establishment of NASCAR layouts at Sonoma and Watkins Glen: the former omitted the Carousel section of the layout from 1998 to 2018 while the latter omits the Boot, again due to handling issues. In the 2010s, NASCAR began refocusing on road courses, with the Xfinity Series competing at

, marking the first time in 13 years the Truck Series visited a road course. Due to the popularity of these races, NASCAR has been adding more road courses to the championship season schedule with races also taking place in rain. In 2021, the Cup Series schedule included seven road courses, with such tracks comprising approximately 19 percent of the calendar compared to eight percent in the past.


Manipulating the outcome of races and championships

NASCAR uses caution flags, triggered by race administrators, in which drivers are limited to certain maneuvers. The general purpose of this event is to reduce risk when track conditions deteriorate (for instance, if there is debris on the track, one or more cars crash and emergency vehicles and tow trucks need to be on track, or a car spins and is given the opportunity to catch up with the field). Generally, when a caution occurs, race cars must tightly pack before a restart. The number of cautions per race in the NASCAR Cup Series increased from 7.4 in 2001 to 9.6 in 2007 (an increase of almost 30%), while the number of actual crashes per race has only increased from 5.6 to 6.7 (an increase of about 20%). This is likely due to increased caution periods for cleaning debris from the track. In 2015, the number of cautions per race averaged at 8.2, showing a gradual decline since then. Fans and competitors alike speculate whether some of these cautions are used to keep the cars tightly packed in an effort to keep a race close. An unnecessary caution at a specific time could affect a driver's strategy and the outcome of the race, while providing a potential opportunity for other drivers to close the gap and prevent a runaway victory. In April 2007, then two-time champion
