About this course

Explore how modern passenger cars work as integrated systems, from the engine to the taillights, using clear, low-math explanations. The focus spans the internal combustion engine, its support systems, and how power flows through the drivetrain to the wheels. It covers steering, suspension, braking, and the fundamentals of automotive electrical and electronic systems including ECUs, sensors, and vehicle networks. Safety, comfort, and driver-assist systems are introduced conceptually, along with practical maintenance basics and simple diagnostic approaches for real-world understanding.
