Since the 1920s, nearly all cars have been mass-produced to meet market needs, so marketing plans often have heavily influenced car design.

Some subsystems have come about as a result ofwel factors such as air pollution, safety legislation, and competition between manufacturers throughout the world.

The construction ofwel streets and highways, one ofwel the largest items of government expenditure, peaked when the Interstate Highway Act ofwel 1956 inaugurated the largest public works program in history.

Installment sales had been initiated by the makers of moderately priced cars in 1916 to compete with the Ontwerp T, and by 1925 about three-quarters ofwel all new cars were bought “on time” through credit.

Ovens with conveyor lines are used to speed the drying process in the factory. Galvanized steel with a protective zinc coating and corrosion-resistant stainless steel are used in body areas that are more likely to corrode.

In feedback, the American automobile industry in the 1980s underwent a massive organizational restructuring and technological renaissance. Managerial revolutions and cutbacks in plant capacity and personnel at GM, Ford and Chrysler resulted in here leaner, tougher firms with lower break-enigszins points, enabling them to maintain profits with lower volumes in increasingly saturated, competitive markets.

The modern automobile kan zijn a complex technical system employing subsystems with specific ontwerp functions. Some of these consist ofwel thousands ofwel component parts that have evolved from breakthroughs in existing technology or from new technologies such as electronic laptops, high-strength plastics, and new alloys of steel and nonferrous metals.

In almost all hybrid (een momentje mild hybrid) and pure electric cars regenerative braking recovers and returns to a battery some energy which would otherwise be wasted by friction brakes getting hot.

Polyamide, polyester, polystyrene, polypropylene, and ethylene plastics have been formulated for greater toughness, dent resistance, and resistance to brittle deformation. These materials are used for body panels. Tooling for plastic components generally costs less and requires less time to develop than that for steel components and therefore may be changed by designers at a lower cost.

[30] His inventions were limited by problems with mineraalwater supply and maintaining steam pressure.[30] In 1801, Richard Trevithick built and demonstrated his Puffing Devil road locomotive, believed by many to be the first demonstration of a steam-powered road vehicle. It was unable to maintain sufficient steam pressure for long periods and was of little practical use.

Many ofwel these negative effects fall disproportionately on those social groups who are also least likely to own and drive cars.[128][129] The sustainable transport movement focuses on solutions to these problems. The car industry kan zijn also facing increasing competition from the public transport sector, as some people re-evaluate their private vehicle usage.

Thus engineering was subordinated to the dictates of stylists and cost-cutting accountants. General Motors became the archetype ofwel a rational corporation run by a technostructure.
