. The car is considered an essential part of the developed economy. Cars have controls for driving, parking, passenger comfort, and a variety of lights. Over the decades, additional features and controls have been added to vehicles, making them progressively more complex. These include rear-reversing cameras, air conditioning, navigation systems, and in-car entertainment. Most cars in use in the early 2020s are propelled by an internal combustion engine, fuelled by the combustion of fossil fuels. Electric cars, which were invented early in the history of the car, became commercially available in the 2000s and are predicted to cost less to buy than gasoline cars before 2025. The transition from fossil fuels to electric cars features prominently in most climate change mitigation scenarios, such as

History

The first working steam-powered vehicle was designed—and quite possibly built—by Ferdinand Verbiest, a Flemish member of a Jesuit mission in China around 1672. It was a scale-model toy for the Kangxi Emperor that was unable to carry a driver or a passenger. – Note that the vehicle pictured is the 20th century diecast model made by Brumm, of a later vehicle, not a model based on Verbiest's plans. It is not known with certainty if Verbiest's model was successfully built or run.
Nicolas-Joseph Cugnot Nicolas-Joseph Cugnot (26 February 1725 – 2 October 1804) was a French inventor who built the world's first full-size and working self-propelled mechanical land-vehicle, the "Fardier à vapeur" – effectively the world's first automobile. B ...

He also constructed two steam tractors for the French Army, one of which is preserved in the French National Conservatory of Arts and Crafts. His inventions were, however, limited by problems with water supply and maintaining steam pressure. In 1801,

It was unable to maintain sufficient steam pressure for long periods and was of little practical use. The development of external combustion engines is detailed as part of the history of the car but often treated separately from the development of true cars. A variety of steam-powered road vehicles were used during the first part of the 19th century, including

patented his Benz Patent-Motorwagen; he is generally acknowledged as the inventor of the car. In 1879, Benz was granted a patent for his first engine, which had been designed in 1878. Many of his other inventions made the use of the internal combustion engine feasible for powering a vehicle. His first ''Motorwagen'' was built in 1885 in Mannheim, Germany. He was awarded the patent for its invention as of his application on 29 January 1886 (under the auspices of his major company, Benz & Cie., which was founded in 1883). Benz began promotion of the vehicle on 3 July 1886, and about 25 Benz vehicles were sold between 1888 and 1893, when his first four-wheeler was introduced along with a cheaper model. They also were powered with four-stroke engines of his own design. Emile Roger of France, already producing Benz engines under license, now added the Benz car to his line of products. Because France was more open to the early cars, initially more were built and sold in France through Roger than Benz sold in Germany. In August 1888, Bertha Benz, the wife of Carl Benz, undertook the first road trip by car, to prove the road-worthiness of her husband's invention. In 1896, Benz designed and patented the first internal-combustion flat engine, called ''boxermotor''. During the last years of the 19th century, Benz was the largest car company in the world with 572 units produced in 1899 and, because of its size, Benz & Cie., became a joint-stock company. The first motor car in central Europe and one of the first factory-made cars in the world, was produced by

By 1895, about 30 vehicles had been built by Daimler and Maybach, either at the Daimler works or in the Hotel Hermann, where they set up shop after disputes with their backers. Benz, Maybach, and the Daimler team seem to have been unaware of each other's early work. They never worked together; by the time of the merger of the two companies, Daimler and Maybach were no longer part of DMG.

. This was a production of a small number of vehicles for Jellinek to race and market in his country. Two years later, in 1902, a new model DMG car was produced and the model was named Mercedes after the Maybach engine, which generated 35 hp. Maybach quit DMG shortly thereafter and opened a business of his own. Rights to the ''Daimler'' brand name were sold to other manufacturers.

Negotiations between the two companies resumed several years later when these conditions worsened, and in 1924, they signed an Agreement of Mutual Interest, valid until the year 2000. Both enterprises standardized design, production, purchasing, and sales and they advertised or marketed their car models jointly, although keeping their respective brands. On 28 June 1926, Benz & Cie. and DMG finally merged as the Daimler-Benz company, baptizing all of its cars Mercedes Benz, as a brand honoring the most important model of the DMG cars, the Maybach design later referred to as the 1902 Mercedes-35 hp, along with the Benz name.

. Selden applied for a patent for a car in 1879, but the patent application expired because the vehicle was never built. After a delay of 16 years and a series of attachments to his application, on 5 November 1895, Selden was granted a US patent () for a two-stroke car engine, which hindered, more than encouraged, development of cars in the US. His patent was challenged by Henry Ford and others, and overturned in 1911. In 1893, the first running, gasoline-powered American car was built and road-tested by the Duryea brothers of Springfield, Massachusetts. The first public run of the Duryea Motor Wagon took place on 21 September 1893, on Taylor Street in Metro Center Springfield. Studebaker, subsidiary of a long-established wagon and coach manufacturer, started to build cars in 1897 and commenced sales of electric vehicles in 1902 and gasoline vehicles in 1904. In Britain, there had been several attempts to build steam cars with varying degrees of success, with Thomas Rickett even attempting a production run in 1860.

The assembly line forced workers to work at a certain pace with very repetitive motions which led to more output per worker while other countries were using less productive methods. In the automotive industry, its success was dominating, and quickly spread worldwide seeing the founding of Ford France and Ford Britain in 1911, Ford Denmark 1923, Ford Germany 1925; in 1921, Citroën was the first native European manufacturer to adopt the production method. Soon, companies had to have assembly lines, or risk going broke; by 1930, 250 companies which did not, had disappeared. Development of automotive technology was rapid, due in part to the hundreds of small manufacturers competing to gain the world's attention. Key developments included electric ignition and the electric self-starter (both by

Sloan who established the idea of different makes of cars produced by one company, called the General Motors Companion Make Program, so that buyers could "move up" as their fortunes improved. Reflecting the rapid pace of change, makes shared parts with one another so larger production volume resulted in lower costs for each price range. For example, in the 1930s, LaSalles, sold by Cadillac, used cheaper mechanical parts made by Oldsmobile; in the 1950s, Chevrolet shared bonnet, doors, roof, and windows with Pontiac; by the 1990s, corporate

says that, in countries that mandate low sulfur gasoline, gasoline-fuelled cars built to late 2010s standards (such as Euro-6) emit very little local air pollution. Some cities ban older gasoline-fuelled cars and some countries plan to ban sales in future. However, some environmental groups say this phase-out of fossil fuel vehicles must be brought forwards to limit climate change. Production of gasoline-fuelled cars peaked in 2017.

User interface

Cars are equipped with controls used for driving, passenger comfort, and safety, normally operated by a combination of the use of feet and hands, and occasionally by voice on 21st-century cars. These controls include a steering wheel, pedals for operating the brakes and controlling the car's speed (and, in a manual transmission car, a clutch pedal), a shift lever or stick for changing gears, and a number of buttons and dials for turning on lights, ventilation, and other functions. Modern cars' controls are now standardized, such as the location for the accelerator and brake, but this was not always the case. Controls are evolving in response to new technologies, for example, the electric car and the integration of mobile communications. Some of the original controls are no longer required. For example, all cars once had controls for the choke valve, clutch,

Electronics and interior

Cars are typically equipped with interior lighting which can be toggled manually or be set to light up automatically with doors open, an entertainment system which originated from car radios, sideways windows which can be lowered or raised electrically (manually on earlier cars), and one or multiple auxiliary power outlets for supplying portable appliances such as mobile phones, portable fridges,

Lighting

Cars are typically fitted with multiple types of lights. These include

Interior lights on the ceiling of the car are usually fitted for the driver and passengers. Some vehicles also have a boot light and, more rarely, an engine compartment light.


Weight

During the late 20th and early 21st century, cars increased in weight due to batteries, modern steel safety cages, anti-lock brakes, airbags, and "more-powerful—if more efficient—engines" and, , typically weigh between . Heavier cars are safer for the driver from a crash perspective, but more dangerous for other vehicles and road users. The weight of a car influences fuel consumption and performance, with more weight resulting in increased fuel consumption and decreased performance. The

, a typical city car, weighs about . Heavier cars include SUVs and extended-length SUVs like the Suburban. Some places tax heavier cars more: as well as improving pedestrian safety this can encourage manufacturers to use materials such as recycled aluminium instead of steel. It has been suggested that one benefit of subsidizing charging infrastructure is that cars can use lighter batteries.


Seating and body style

Most cars are designed to carry multiple occupants, often with four or five seats. Cars with five seats typically seat two passengers in the front and three in the rear.
Full-size car Full-size car—also known as large car—is a vehicle size class which originated in the United States and is used for cars larger than mid-size cars, it is the largest size class for cars. In Europe, it is known as E-segment or F-segment. ...
s and large sport utility vehicles can often carry six, seven, or more occupants depending on the arrangement of the seats. On the other hand, sports cars are most often designed with only two seats. The differing needs for passenger capacity and their luggage or cargo space has resulted in the availability of a large variety of body styles to meet individual consumer requirements that include, among others, the sedan/saloon, hatchback, station wagon/estate, and minivan.


Safety

Traffic collisions are the largest cause of injury-related deaths worldwide. Mary Ward became one of the first documented car fatalities in 1869 in Parsonstown, Ireland, and Henry Bliss one of the US's first pedestrian car casualties in 1899 in New York City. There are now standard tests for safety in new cars, such as the Euro and US NCAP tests, and insurance-industry-backed tests by the Insurance Institute for Highway Safety (IIHS).


Costs and benefits

The costs of car usage, which may include the cost of: acquiring the vehicle, repairs and auto maintenance, fuel, depreciation, driving time, parking fees, taxes, and insurance, are weighed against the cost of the alternatives, and the value of the benefits—perceived and real—of vehicle usage. The benefits may include on-demand transportation, mobility, independence, and convenience, and emergency power. During the 1920s, cars had another benefit: " uples finally had a way to head off on unchaperoned dates, plus they had a private space to snuggle up close at the end of the night." Similarly the costs to society of car use may include; maintaining roads, land use, air pollution,

Environmental effects

Cars are a major cause of urban air pollution, with all types of cars producing dust from brakes, tyres, and road wear, although these may be limited by vehicle emission standards. While there are different ways to power cars most rely on
gasoline Gasoline (; ) or petrol (; ) (see ) is a transparent, petroleum-derived flammable liquid that is used primarily as a fuel in most spark-ignited internal combustion engines (also known as petrol engines). It consists mostly of organi ...
or diesel, and they consume almost a quarter of world oil production . Both gasoline and diesel cars pollute more than electric cars. Cars and vans caused 8% of direct carbon dioxide emissions in 2021. , due to greenhouse gases emitted during battery production, electric cars must be driven tens of thousands of kilometers before their lifecycle carbon emissions are less than fossil fuel cars; however this varies considerably and is expected to improve in future due to lower carbon electricity, and longer lasting batteries produced in larger factories. Many governments use fiscal policies, such as

s. High fuel taxes or cultural change may provide a strong incentive for consumers to purchase lighter, smaller, more fuel-efficient cars, or to not drive. The lifetime of a car built in the 2020s is expected to be about 16 years, or about if driven a lot. According to the International Energy Agency fuel economy improved 0.7 per cent in 2017, but an annual improvement of 3.7 per cent is needed to meet the Global Fuel Economy Initiative 2030 target. The increase in sales of SUVs is bad for fuel economy. Many cities in Europe, have banned older fossil fuel cars and all fossil fuel vehicles will be banned in Amsterdam from 2030. Many Chinese cities limit licensing of fossil fuel cars, and many countries plan to stop selling them between 2025 and 2050. The manufacture of vehicles is resource intensive, and many manufacturers now report on the environmental performance of their factories, including energy usage, waste and water consumption. Manufacturing each kWh of battery emits a similar amount of carbon as burning through one full tank of gasoline. The growth in popularity of the car allowed cities to sprawl, therefore encouraging more travel by car resulting in inactivity and

Autonomous car

Fully autonomous vehicles, also known as driverless cars, already exist as robotaxis but have a long way to go before they are in general use.


Open source development

There have been several projects aiming to develop a car on the principles of
open design The open-design movement involves the development of physical products, machines and systems through use of publicly shared design information. This includes the making of both free and open-source software (FOSS) as well as open-source hardwar ...
, an approach to designing in which the plans for the machinery and systems are publicly shared, often without monetary compensation. None of the projects have succeeded in developing a car as a whole including both hardware and software, and no mass production ready open-source based designs have been introduced. Some car hacking through on-board diagnostics (OBD) has been done so far.


Car sharing

Car-share arrangements and

produces by far the most (20 million in 2020), followed by Japan (seven million), then Germany, South Korea and India. The largest market is China, followed by the US. Around the world, there are about a billion cars on the road; they burn over of gasoline and diesel fuel yearly, consuming about of energy. The numbers of cars are increasing rapidly in China and India. In the opinion of some, urban transport systems based around the car have proved unsustainable, consuming excessive energy, affecting the health of populations, and delivering a declining level of service despite increasing investment. Many of these negative effects fall disproportionately on those social groups who are also least likely to own and drive cars. The sustainable transport movement focuses on solutions to these problems. The car industry is also facing increasing competition from the public transport sector, as some people re-evaluate their private vehicle usage.

Other meanings

The term ''motorcar'' was formerly also used in the context of electrified rail systems to denote a car which functions as a small locomotive but also provides space for passengers and baggage. These locomotive cars were often used on suburban routes by both interurban and intercity railroad systems.
