Pinks is a franchise series of television programs on Speed Channel based on drag racing. The original debuted in 2005, with the spinoff Pinks: All Out following in 2006. The name of the show, and the tagline "Lose the race - lose your ride", refer to common slang of pink slips representing a vehicle's title document recording ownership, and the derivative street-racing phrase, "racing for pinks," meaning a race in which the winner earns the loser's car. (In California, until recently, the vehicle title was on a pink slip of paper.)

The series airs on the Speed Channel in the United States and Canada, and also airs on Fox Sports 3 in Australia.

Competitors compete in a drag race (although in the original Pinks, there was a stepladder shifter kart race in Series 1) in the franchise. The formats differ between the franchise's formats - Source

The Grand American Road Racing Association was established in 1999 and is located in Daytona Beach, Florida, near the homes to NASCAR, International Speedway Corporation (ISC), and Daytona International Speedway. Although originated by some members of the NASCAR community, Grand-Am centers on different styles of racing including sports car racing, touring car racing, and motorcycle racing on road racing circuits throughout North America.

On September 4, 2008, NASCAR Holdings announced their buyout of the Grand American Road Racing Association in an attempt to merge communications, research, and marketing resources into a single entity, while allowing each organization to continue to control their own racing series

The premiere series of Grand-Am is the Rolex Sports Car Series which originated in 2000 as a successor to the defunct United States Road Racing Championship. Combining classes of Sports Racing Prototypes and Grand Touring-style production-based cars, the series is centered around the 24 Hours of Daytona but includes a wide variety of American, Canadian, and Mexican tracks.

Since 2003 the series has replaced their Sports Racing Prototypes with new Daytona Prototypes, a custom-built class built specifically for the Rolex Series. These cost-effective race cars offer a relatively economical racing environment in which technology is carefully controlled to ensure close racing and approximate parity between different chassis and engines.

The GT classes have also been simplified over the years, allowing for a variety of American, European, and Japanese manufacturers to participate including Chevrolet, Pontiac, BMW, Porsche, and Mazda. Rules allow for tuned production cars or custom tube frame chassis to be used, letting participants save cost if necessary.

DPs and GTs usually share the track although do occasionally race separately, typically at shorter circuits.

MotoGP, the premier class of GP motorcycle racing, has changed dramatically in recent years. From the mid-1970s until 2002 the top class of GP racing allowed 500cc with a maximum of 4 cylinders, regardless of whether the engine was a two-stroke or four-stroke.

Consequently, all machines were two-strokes, due to the greater power output for a given engine capacity. Some two- and three-cylinder two-stroke 500s were seen, but though they had a minimum-weight advantage under the rules, typically attained higher corner speed and could qualify well, they lacked the power of the four-cylinder machines.

In 2002, rule changes were introduced to facilitate the phasing out of the two strokes, probably influenced by what was then seen as a lack of relevance: the last mass-produced 500cc 2-stroke model had not been available to the public for some 15 years. The rules permitted manufacturers to choose between running two-strokes engines (500cc or less) or four-strokes (990cc or less). Manufacturers were also permitted to employ their choice of engine configuration.

Despite the significantly increased costs involved in running the new four-stroke machinery, given their extra 490cc capacity advantage, the four-strokes were soon able to dominate their two-stroke rivals. As a result, by 2003 no two-stroke machines remained in the MotoGP field. The 125cc and 250cc classes still consist exclusively of two-stroke machines. In 2007, the MotoGP class had its maximum engine displacement capacity reduced to 800cc for a minimum of 5 years.

Kart racing or karting is a variant of open-wheel motor sport with simple, small four-wheeled vehicles called karts, go-karts, or gearbox/shifter karts depending on the design. They are usually raced on scaled-down circuits. Karting is commonly perceived as the stepping stone to the higher and more expensive ranks of motorsports.

Karts vary widely in speed and some (known as Superkarts) can reach speeds exceeding 160 mph (250 km/h), while go-karts intended for the general public in amusement parks may be limited to speeds of no more than 15 mph (25 km/h). A KF1 kart, with a 125 cc 2-stroke engine and an overall weight including the driver of 150 kilograms has a top speed of 85 mph (140 km/h). It takes a little more than 3 seconds to go from 0 to 60 mph with a 125 cc shifter kart (6 gears), with a top speed of 115 mph (185 km/h) on long circuits. - Source

In North American auto racing, particularly with regard to NASCAR, a short track is a racetrack of less than one mile (1.6km) in length. Short track racing, often associated with fairgrounds and similar venues, is where stock car racing first got off of the back roads and into organized and regulated competition. Many traditional fans and purists still see short track racing as the "real" NASCAR, because the lower speeds make "paint swapping," where the bodies of the cars actually rub against one another, practical without a very high likelihood of serious accidents. In fact, NASCAR sanctions such "club" racing, offering the Whelen All-American Series as a national championship for the drivers, and an invitational race for club racers, the Toyota All-Star Showdown, a 150-lap race featuring the common Super Late Models with NASCAR-established rules. In 2007, NASCAR is increasing marketing of the short tracks with the "NASCAR Home Tracks" campaign, with Greg Biffle, Elliott Sadler, and Carl Edwards featured in advertising to market short track racing. In some cases a Sprint Cup star or two will race in a weekly short-track event held usually on a short track near that week's race, or in a midweek special, such as the Slinger Nationals at Wisconsin's Slinger Super Speedway, a quarter-mile track (but is not NASCAR-sanctioned).

Ken Schrader, Tony Stewart, and Dale Earnhardt, Jr. all own short tracks, most of them being dirt. Stewart owns the Eldora Speedway, which features Sprint Cup stars and other nationally recognised drivers in the "Prelude to the Dream" dirt late model race. Dale Earnhardt, Jr. is a partner in the Paducah (Kentucky) International Speedway.

In recent years, there has been a gradual push away from short track venues for Sprint Cup (the highest level of NASCAR) in favor of longer tracks. This is due to larger venues having accommodations for more fans (although the short track in Bristol, Tennessee, Bristol Motor Speedway, now has over 160,000 seats) and higher speeds - Source
