    Study Notes

    Car Design Process

    • Many people contribute to the creation of a new car, including design engineers, production engineers, and researchers.
    • Car manufacturers research the market to find out what drivers want before releasing a new model.
    • Designers use paper sketches, wireframe images, and full-size clay models to develop a car's design.
    • Industrial designers create detailed technical drawings using computer-aided design (CAD) programs.
    • CAD programs show the final shape of the car and allow manufacturers to make changes to the design easily.

    Prototype Development

    • Once the design is set, a manufacturer builds a prototype full-size model of the car.
    • The prototype is tested for safety, comfort, roadholding, engine response, and overall performance.
    • The prototype helps manufacturers see how all the different parts of the car fit together.

    Modern Motoring

    • Modern car manufacturing is dominated by computer technology.
    • Computer-controlled engines monitor performance and keep the car working with maximum efficiency.
    • Sensors detect information such as fuel and air intake, engine temperature, and other data.
    • The onboard computer makes continual adjustments to the car's running based on this data.
    • The computer also controls features like airbags and anti-lock braking systems (ABS) to ensure safety.

    Car Manufacturing Statistics

    • By 2014, there were over one billion vehicles on the world's roads.
    • More than 50 million new cars are added to the roads every year.
    • The huge number of cars on the road contributes to air pollution and city center congestion.

    Environmental Concerns

    • Manufacturers are making cars with engines that create less pollution.
    • Computer controls help cut down exhaust emissions.
    • Smart sensors in the engine control unit monitor fuel consumption to ensure emissions are kept within an acceptable range.
    • Modern cars are built with streamlined, aerodynamic shapes to reduce drag and air resistance.
    • The shape of the car is tested in a wind tunnel to ensure minimum drag.
    • Smooth, long, low cars push through the air more easily, reducing fuel consumption and emissions.
