1. Overview

The automotive industry encompasses the design, development, manufacturing, marketing, and servicing of motor vehicles. It is one of the largest global industries and a major driver of technological innovation and economic growth.

2. Main Components

Powertrain System: Includes the engine, transmission, driveshafts, and axles—responsible for generating and transmitting power to move the vehicle.

Chassis System: Provides structural support and includes the frame, suspension, steering, and braking systems.

Electrical & Electronic Systems: Manage lighting, infotainment, sensors, ECUs (Electronic Control Units), and vehicle networks (CAN, LIN, etc.).

Body & Interior Systems: Cover the exterior design, safety structures, and comfort features such as seats, climate control, and trim.

3. Key Technologies

Internal Combustion Engines (ICE): Traditional petrol and diesel engines with ongoing improvements for efficiency and emission control.

Electric & Hybrid Vehicles: Use electric motors and batteries to reduce fuel consumption and emissions.

Autonomous Driving: Involves sensors, AI, and machine learning to enable self-driving features.

Connectivity: Integration of IoT, GPS, and telematics for real-time monitoring and smart mobility.

Advanced Safety Systems: ABS, ESP, airbags, lane assist, adaptive cruise control, and collision avoidance systems.

4. Environmental & Economic Impact

Environmental: Major contributor to CO₂ emissions; shift toward sustainable mobility and renewable energy sources.

Economic: Provides millions of jobs globally, supports industries like steel, electronics, and rubber, and influences GDP growth.

5. Future Trends
