Motorsport, motor sports or motor racing is a worldwide popular term used to cover the category of sporting events that feature the use of advanced motorized vehicles, often for competition or non-competitive activity. The modern definition of the term has evolved over the years, taking into consideration the ever-evolving motorsport activities and the development of new technological advancements. In recent years, it has come to be defined as an event that showcases competitive driving skills in a race car environment. It can also be defined as an event that involves any form of vehicle driving, be it road vehicles or aircraft.

The motorsport term is often used in international contexts, particularly when referencing events that take place in different countries, such as Formula One, rallying, motor racing, motorbike racing and NASCAR. The definition given for each event may vary slightly from one country to another, depending on the nature of the event in question and the nature of the country hosting the race. In addition to the countries mentioned, there are many international motor sports organizations that have developed their own definitions of the sport. For instance, the Geneva Motor Show, which is one of the largest gatherings of automobile and motorcycle makers across the world, defines motorsport as a competition of automobile driving in which the vehicles are driven by professional drivers in a set environment, usually without modifications. In addition, various international standards have been developed in order to set benchmarks against which cars, trucks, bikes, planes and even hovercraft can be compared.

The significance of motorsport as a lifestyle and business proposition has become undeniable over the past few decades. The popularity of Formula One races on the national stage and the growing recognition of supercar manufacturers as global brands have contributed to the surge of interest in motorsport and the branding of cars, trucks and drivers with prominent logos. Brands that have been associated with Formula One include Ferrari and BMW, who have both used their association with the sport to solidify their place in the hearts and minds of enthusiasts. Additionally, NASCAR, which is the National Association for Stock Car Auto Racing, has made great strides in establishing itself as a credible title sponsor and in building an image that carries tremendous respect among drivers and fans.
