Automotive industry

The automotive industry comprises a wide range of companies and organizations involved in the design, development, manufacturing, marketing, selling, repairing, and modification of motor vehicles. It is one of the world's largest industries by revenue (from 16% such as in France up to 40% in countries such as Slovakia).^{[failed verification]}

The word automotive comes from the Greek autos (self), and Latin motivus (of motion), referring to any form of self-powered vehicle. This term, as proposed by Elmer Sperry^{[need quotation to verify]} (1860–1930), first came into use to describe automobiles in 1898.

The automotive industry began in the 1860s with hundreds of manufacturers pioneering the horseless carriage. Early car manufacturing involved manual assembly by a human worker. The process evolved from engineers working on a stationary car to a conveyor belt system where the car passed through multiple stations of more specialized engineers. In the 1960s, robotic equipment was introduced, and most cars are now mainly assembled by automated machinery.

For many decades, the United States led the world in total automobile production, with the U.S. Big Three General Motors, Ford Motor Company, and Chrysler being the world's three largest auto manufacturers for a time, and G.M. and Ford remaining the two largest until the mid-2000s. In 1929, before the Great Depression, the world had 32,028,500 automobiles in use, of which the U.S. automobile enterprises produced more than 90%. At that time, the U.S. had one car per 4.87 persons. After 1945, the U.S. produced around three-quarters of the world's auto production. In 1980, the U.S. was overtaken by Japan and then became a world leader again in 1994. Japan narrowly passed the U.S. in production during 2006 and 2007, and in 2008 also China, which in 2009 took the top spot (from Japan) with 13.8 million units, although the U.S. surpassed Japan in 2011, to become the second-largest automobile industry. In 2024, China produced more than 31 million vehicles in a year, after breaking 30 million in 2023, reaching 29 million for the first time in 2017 and 28 million the year before. In 2024, China produced the most passenger cars in the world, with Japan, India, Germany, and South Korea trailing. This was achieved by Chinese car companies signing joint ventures with foreign manufacturers. From 1970 (140 models) to 1998 (260 models) to 2012 (684 models), the number of automobile models in the U.S. has grown exponentially.

Safety is a state that implies being protected from any risk, danger, damage, or cause of injury. In the automotive industry, safety means that users, operators, or manufacturers do not face any risk or danger coming from the motor vehicle or its spare parts. Safety for the automobiles themselves implies that there is no risk of damage.

Safety in the automotive industry is particularly important and therefore highly regulated. Automobiles and other motor vehicles have to comply with a certain number of regulations, whether local or international, in order to be accepted on the market. The standard ISO 26262, is considered one of the best practice frameworks for achieving automotive functional safety.

In case of safety issues, danger, product defect, or faulty procedure during the manufacturing of the motor vehicle, the maker can request to return either a batch or the entire production run. This procedure is called product recall. Product recalls happen in every industry and can be production-related or stem from raw materials.

Product and operation tests and inspections at different stages of the value chain are made to avoid these product recalls by ensuring end-user security and safety and compliance with the automotive industry requirements. However, the automotive industry is still particularly concerned about product recalls, which cause considerable financial consequences.
