American autocross is a form of autocross, an individual motorsport in which drivers compete to set the fastest time on a temporary course. Events are usually held on large paved areas, such as parking lots or airfields. Courses consist of turns, offsets, and slaloms marked by traffic cones; new courses are typically created for each event.
Autocross is a timed competition in which drivers navigate one at a time through a defined course on either a sealed or an unsealed surface. It is a form of motorsports that emphasizes safe competition and active participation. Autocross differs from road racing and oval racing in that generally there is only one car on the track, driving against the clock rather than other cars. As an entry-level motorsport it provides a stepping stone for drivers looking to move into other more competitive and possibly expensive forms of racing.

Autograss racing a form of amateur motor racing in Britain. Races are held at venues throughout the UK and Ireland. Its origins can be traced back to the 1960s.

AutoSolo in the United Kingdom is a form of Motorsport-based around the principles of autotesting, the main differences being that the tests are run in a forward direction only and are usually slightly faster and more open than traditional Autotests. Courses are usually larger than those for Autotesting, and as the courses are laid out to run in one direction, it is common for more than 1 car to be on the course at the same time. Autosolos are similar to the popular American motorsport of autocross also formerly-known as Solo2. Solo2 is a registered service mark of the Sports Car Club of America (SCCA). SCCA now refers to this sport simply as "Solo". The generic term used in the US is "Autocross".
Bandolero car racing is a type of entry-level racing in the United States and Canada. Many bandolero car drivers move into Legends racing. Cars can reach in excess of 70 mph, but do not accelerate very quickly. The most wins in Bandolero race cars used to be held by Joey Logano but was broken in 2016 by Clay Thompson. The cars are built like miniature stock cars, with a tube frame and sheet metal cage. Drivers enter through the roof of the vehicle. Most drivers range from 8 to 14 years old, but older drivers can also race. The cars race on 1/4 mile, 3/8 mile and 4/10 mile ovals and also road courses and dirt tracks. Currently, there are two divisions in Bandolero racing.

Banger racing is a tarmac, dirt, shale and chalk track type of motorsport event popular in countries such as the United Kingdom, Ireland, Belgium and the Netherlands. Old scrap vehicles are raced against one another, with the winner being the first to the checkered flag after a set number of laps. Contact to damage an opponent's car is sometimes permitted and encouraged within the formula, with cars progressively becoming more damaged throughout the meeting. Races are held at an oval or tri-oval circuits that are up to 1⁄4 mile long; however, on certain occasions, races are held in a figure of eight configurations. Banger racing is often confused with stock car racing, although there are differences between the two, despite often racing at the same tracks.
Classic trials, or colloquially mud plugging, is one of the oldest forms of rallying or off-road motor sports, dating from the beginning of the 20th century. Originally, the challenge was just to complete a long (challenging) road course. All three Motor Cycling Club long distance trials in the UK – the Land's End, the Exeter and the Edinburgh – date from that time, and are still held today.

Crosskart or off-road kart is a type of kart racing that takes place on autocross, rallycross, dirt oval or ice racing tracks instead of on paved tracks.
Demolition derby is a motorevent usually presented at county fairs and festivals. While rules vary from event to event, the typical demolition derby event consists of five or more drivers competing by deliberately ramming their vehicles into one another. The last driver whose vehicle is still operational is awarded the victory. Demolition derbies originated in the United States and quickly spread to other Western nations. For example, Australia's first demolition derby took place in January 1963.
Desert racing is the act of racing through the desert in a two- or four-wheeled off-road vehicle. Races, which generally consist of two or more loops around a course covering up to 4,660 miles (7,500 km), can take the form of Hare and Hound or Hare scramble style events, and are often laid out over a long and harsh track through relatively barren terrain.
Drag racing is a type of motor racing in which automobiles or motorcycles compete, usually two at a time, to be first to cross a set finish line. The race follows a short, straight course from a standing start over a measured distance, most commonly 1⁄4 mi, with a shorter distance becoming increasingly popular, as it has become the standard for Top Fuel dragsters and funny cars, where some major bracket races and other sanctioning bodies have adopted it as the standard. The 1⁄8 mi is also popular in some circles. Electronic timing and speed sensing systems have been used to record race results since the 1960s.

Endurance racing is a form of motorsport racing which is meant to test the durability of equipment and endurance of participants. Teams of multiple drivers attempt to cover a large distance in a single event, with participants given a break with the ability to change during the race. Endurance races can be run either to cover a set distance in laps as quickly as possible, or to cover as much distance as possible over a preset amount of time.

Figure 8 racing is a form of stock car racing in which automobiles race on a track that purposely intersects itself, increasing the risk of collisions. Figure 8 racing is most common and popular in the United States and Canada. Because of the risk of collisions, figure 8 racing bears some similarity to the chiefly European sport of banger racing.

Hillclimbing is a branch of motorsport in which drivers compete against the clock to complete an uphill course.

Historic motorsport or vintage motorsport, is motorsport with vehicles limited to a particular era. Only safety precautions are modernized in these hobbyist races. A historical event can be of various types of motorsport disciplines, from road racing to rallying.

Lawnmower racing is a form of motorsport in which competitors race modified lawnmowers, usually of the ride-on or self-propelled variety. The original mower engines are retained, but blades are removed for safety. The sport attracts all ages, and is usually entered into in a spirit of fun rather than extreme competitiveness, though many participants do take it seriously.

Legends car racing is a style of auto racing designed primarily to promote exciting racing and to keep costs down. The race car bodyshells are 5/8-scale replicas of American automobiles from the 1930s and 1940s, powered by a Yamaha XJ1250, FJ1200, or starting in 2018, FZ09 (water-cooled) engine. The worldwide sanctioning body for legends car racing is INEX.

Modified stock car racing, also known as modified racing and modified, is a type of auto racing that involves purpose-built cars simultaneously racing against each other on oval tracks. First established in the United States after World War II, this type of racing was early-on characterized by its participants' modification of passenger cars in pursuit of higher speeds, hence the name.
Oval track racing is a form of closed-circuit motorsport that is contested on an oval-shaped race track. An oval track differs from a road course in that the layout resembles an oval with turns in only one direction, and the direction of traffic is almost universally counter-clockwise. Oval tracks are dedicated motorsport circuits, used predominantly in the United States. They often have banked turns and some, despite the name, are not precisely oval, and the shape of the track can vary.

Pickup truck racing is a form of auto racing which involves modified versions of pickup trucks on racing circuits, mostly oval tracks. Race pickup trucks are mechanically similar to coupé-shaped stock cars, with the main difference being the more boxy shape of the cab, which does not have as good aerodynamics as stock cars.

Rally raid, also known as cross-country rallying, is a form of long distance off-road racing that takes place over several days. The length of the event can be as short as 2–3 days for a cross-country baja to as long as 15 days with marathon rallies like the Dakar Rally; with other cross-country rally events lasting 4–5 days. With skill in navigation being key, the driving skill and endurance of riders, drivers, co-drivers, and machines are put to the test. The total distance covered can be anywhere between 600 km to over 5,000 km with terrain ranging from sandy dunes, forest roads, mountain roads, and dry river beds; among others.

Rallycross is a form of sprint style automobile racing, held on a closed mixed-surface racing circuit, with modified production or specially built road cars, similar to the World Rally Cars. It is mainly popular in the Nordic countries, the Netherlands, Belgium, France and Great Britain. An inexpensive, entry level type of rallycross is the Swedish folkrace or its Norwegian counterpart, the so-called bilcross. The folkrace is most popular in Finland where it was founded back in late 60's. In Europe, rallycross can also refer to racing 1:8 scale off-road radio-controlled buggies.

Rally is a form of motorsport that takes place on public or private roads with modified production or specially built road-legal cars. It is distinguished by not running on a circuit, but instead in a point-to-point format in which participants and their co-drivers drive between set control points, leaving at regular intervals from one or more start points. Rallies may be won by pure speed within the stages or alternatively by driving to a predetermined ideal journey time within the stages.
Road racing is a form of motorsport racing held on a paved road surfaces. The races can be held either on a closed circuit or on a street circuit utilizing temporarily closed public roads. Originally, road races were held almost entirely on public roads however, public safety concerns eventually led to most races being held on purpose built racing circuits.

Short course off road racing is a form of auto racing involving the racing of modified vehicles on a dirt road closed course of a short length. It is distinct from long course desert racing such as the Baja 1000, which consists of racing at least hundreds of kilometers / miles over a quasi linear (non-closed) course from one point to another.

Sports car racing is a form of motorsport road racing which utilises sports cars that have two seats and enclosed wheels. They may be purpose-built (Prototype) or related to road-going models. Broadly speaking, sports car racing is one of the main types of circuit auto racing, alongside open-wheel single seater racing, touring car racing and stock car racing. Sports car races are often endurance races that are run over relatively large distances, and there is usually a larger emphasis placed on the reliability and efficiency of the car than in some of the other types of auto racing. The FIA World Endurance Championship is an example of a sports car racing series.

Supermodifieds are a class of open wheel race car that compete on paved short tracks throughout the United States of America and Canada. The class was founded in the 1950s and is especially popular in the Western states, the Northeast and Great Lakes regions.

Touring car racing is a motorsport road racing competition with heavily modified road-going cars. It is popular in Argentina, Australia, New Zealand, Brazil, Britain, Germany, Sweden and Denmark. It has both similarities to and significant differences from stock car racing, which is popular in the United States.

Truck racing is a form of motorsport road racing which involves modified versions of heavy tractor units on road racing or oval track circuits.
